Malunggay Bark Extract As Alternative Source

Malunggay Bark Extract As Alternative Source The 21st century trend is an era in which technologies become part of human lives. In this age, efforts and time are exhausted by many individuals or groups in order to create technologies that can be utilized in any human endeavour. Conversely, for most of these innovations and inventions to function, electricity is required. In the Philippines, a country that is abreast with technologies, majority of the electricity requirement is derived from electric power plants that are run by fossil fuels such as petroleum and coal. Moreover, batteries which are portable source of the said energy are also in use. However, due to rapid increase in technologies that require electricity, some problems arise. At present, since there is a huge demand for electricity, fuel required to generate such energy becomes scarce. People have realized that most of processes and materials for electricity generation have negative effect on the environment and on health of human. Hence, researches are conducted to discover green (clean, natural, derive from biological source), low cost, and readily available alternative source of electricity. In line with this view, Filipinos actively participate to achieve this purpose by introducing malunggay (Moringa oleifera) as an important source of not only nutrition and medicine but of electricity as well. Malunggay is a tree that preferably grows in countries with tropical climate such as the Philippines. This tree can be easily propagated since malunggay can be grown from seeds or mature stem cuttings. In the country, this tree is commonly found in household backyard, aligned with perimeter fences, since the edible and nutritious flowers, fruits, and leaves of malunggay are part of the diet of Filipinos. Aside from the nutritional value of some parts of malunggay, all parts of this tree are used in herbal medicine to cure some diseases. Given that this tree can serve several purposes, malunggay becomes in demand. In light of the discussion of the environmental problems and characteristics of malunggay, a group of researchers conducted a study entitled MOB Electricity: Malunggay Bark Extract as Alternative Source of Electricity, to show that malunggay (Moringa oleifera) bark extract is a viable alternative source of electricity; consequently, providing an environment friendly, inexpensive and accessible source of electricity. At this point in time, since there is a strong desire to improve way of living, great attention is given to technologies. Due to this interest, innovations and inventions which require electricity are continuously developed. Thus, electricity must be continuously generated. On the contrary, most of the processes and materials for electricity generation pose hazards to the environment and human health. Therefore, a clean, low cost, and readily available source of electricity is needed, a reason that motivated the researchers to engage in this investigatory project. B. Statement of the Problem This study entitled MOB Electricity: Malunggay Bark Extract as Alternative Source of Electricity intends to investigate the feasibility of Malunggay (Moringa oleifera) bark extract as an alternative source of electricity. Specifically, this study sought to answer the following questions: 1. Is there a significant difference on the amount of voltage measured from liquid form of malunggay bark extract obtained through crude and ethanol extraction? 2. Is there a significant difference on the amount of voltage measured from jelly form of malunggay bark extract obtained through crude and ethanol extraction? 3. Is there a significant difference on the amount of voltage measured from liquid and jelly form of malunggay bark extract obtained through crude and ethanol extraction? 4. Is there a significant difference on the amount of voltage measured from varying amounts of malunggay bark extract? C. Hypotheses 1. Ho: There is no significant difference on the amount of voltage measured from liquid form of malunggay bark extract obtained through crude and ethanol extraction. Ha: There is a significant difference on the amount of voltage measured from liquid form of malunggay bark extract obtained through crude and ethanol extraction. 2.

Ho: There is no significant difference on the amount of voltage measured from varying amounts of malunggay bark extract. Ha: There is a significant difference on the amount of voltage measured from varying amounts of malunggay bark extract. D. Significance of the Study This study will provide the energy sector in the country a green alternative source of electricity which will reduce the use of materials that have hazardous effects to human and environment. Hence, minimizing occurrences of diseases and slowing the rate of environment degradation. Furthermore, the positive result of this study could also assure people with inexpensive and accessible source of electricity. Moreover, this study introduces a new application of malunggay, thus, further increasing the demand for this tree. In this effect, farmers in the country could have extra income by providing the needed supply of malunggay. E. Scopes and Limitations The focal point of this study is the feasibility of malunggay (Moringa oleifera) as an alternative source of electricity. In order to assess the said feasibility, malunggay bark extract obtained through crude and ethanol extraction was utilized. Subsequently, voltage was measured for different set-ups and treatments. However, the researchers were unable to determine the component of the extract responsible for electricity generation since the material was not subjected to chemical analysis. This restriction might be an additional recommendation for future researches. The researchers conducted this study from January 9, 2012 to August 23, 2012. All experiments and observations were done at JICA laboratory of Sapang Palay National High School. F. Operational Definition of Terms Gelatin Powder used to create a firm form of extract. Carbon Rod -served as the positive electrode (anode) of the external circuit connected to malunggay bark exract. Zinc Plate served as the negative electrode (cathode) of the external circuit connected to malunggay bark extract. Multi-tester used to measure the amount of voltage from malunggay bark extract. CHAPTER II REVIEW OF RELATED LITERATURE I. Introduction In the onset of the 21st century, negative effects of environmental issues such as pollution, ozone depletion, and global warming become notable. Thus, these problems gained the attention of people around the world. Among these negative effects are development and widespread of diseases, development of skin cancer, increase in temperature, heavy rains, heavy floods, strong typhoons, and climate change. In response, organizations are created, and conventions and researches are conducted to deal with these issues. Today, as data are continuously gathered;various human activities that involve emission of gases, chemicals, and radiations are considered as one of the large contributor to environmental degradation. Such human activities include generation of electricity. However, since electricity is vital in operating technologies which advances human lives, search for clean alternative source of electricity should be conducted to prevent further degradation of the environment. II. Electricity Generation Electricity is the form of energy that has the highest demand at this point in time. This energy form is required to operate technologies that people created for life advancement. Thus, energy industries are in continuous search to supply the needed demand of electricity. Today, there are different sources from which this energy is derived. These sources include fossil fuels (petroleum and coal), nuclear energy, hydropower, solar energy, and wind energy. These sources are used to drive turbines in electric power plants which will generate electricity. Electricity generated from these sources is the one supplied in wall sockets of houses and buildings. Another source of electricity is battery, a source that is in portable form. (Bose, 2010) In the Philippines, a country that is abreast with technologies, majority of the required electricity is derived from electric power plants that are run by fossil fuels such as petroleum and coal. Moreover, batteries which are portable source of the said energy are also in use. However, emissions from such electric power plants are composed of gases which cause air pollution and contribute to global warming. Likewise, batteries have chemical components that can leak and pollute land, water and air. In addition to these negative effects to the environment, human can also acquire diseases due to said contamination. (Petrina, 2007) III. Green Electricity People are now aware of the harmful effects of conventional electricity generation to human health and environment. Consequently, efforts and time are spent in order to discover alternative green clean, natural, biological sources of electricity, an action that would minimize presence of harmful chemicals and gases in the environment. In connection to this notion, researchers have considered different plants, different parts of plants, and organisms as potential source of green electricity. (U.S Environmental Protection Agency, 2012) Basic example of green energy is electricity from fruits and vegetables. Many people, during childhood, have done classroom experiments to derive electricity from lemon and potato. Results of these experiments proved that these materials can generate electricity because juices of fruits and vegetables act as electrolytes which initiate reaction to free and move electrons. (Renico, 2012) On the other hand, another related research was conducted by scientists of Stanford University which harness electricity from algae. The concept behind this project is the process of photosynthesis involved in food production of plants. According to the scientists, in this process, electrons from water are given with high energy by sunlight. These electrons are the one the scientists captured using electrodes. (Stanford University, 2010) Lastly, researchers of Arizona State University study the possibility for bacteria to generate electricity through the use of a microbial fuel cell (MFC) which contains waste water and bacteria dwelling on the material. In this research, the persons involve relate electricity generation to metabolic activity of bacteria. (Arizona State University, 2008) IV. Malunggay Tree Malunggay (Moringa oleifera) tree, which commonly grows in tropical countries such as Philippines, is characterized by long, straight, white trunks; small, green, compound leaves; and seasonal white flowers that yields long pods. This tree propagates easily and does not require much attention. In fact, malunggay seeds or matured stem cuttings can be planted in any kind of soil and does not require regular maintenance. (Asia Green Group, 2012) In the Philippines, malunggay can be found in most household backyards because edible parts of this tree (flowers, pods, and leaves) are part of Filipino cooking. Moreover, these parts of malunggay tree provide people with vitamins and minerals needed by the body. Aside from providing nourishment, this tree also has medicinal value. Based on numerous studies, malunggay contains chemicals that have antibacterial, anticancer, and anti-inflammatory properties. (Fahey, 2005) CHAPTER III METHODOLOGY Gathering of Materials/Equipments Among the materials gathered by the researchers were malunggay (Moringa olifera) bark, gelatin powder, ethyl alcohol, filter paper, gloves, face mask, and old batteries. Equipment as well was borrowed from the school laboratory. These equipments include beakers, reagent bottles, funnel, stirring rod, thermometer, mortar and pestle, alcohol lamp, triple beam balance, strainer, tripod, and wire gauze. Collection of Zinc Plate and Carbon Rod Researchers collected old batteries. Subsequently, these batteries were uncovered and electrolyte inside was removed. Since electrolyte component of battery is composed of slightly toxic chemicals, researcher wore gloves and face mask. In this manner, zinc plates and carbon rods were obtained. Preparation of Malunggay Bark Extract A. Crude Extraction Malunggay barks were collected and cut into small pieces by the researchers. Afterwards, the barks were placed in a blender. Finally, in order to obtain pure extract, minced barks were placed in soft cloth and squeezed. B. Ethanol Extraction Malunggay barks were collected and cut into small pieces. Then, barks were placed in a blender to mince the material. Next, minced barks were oven-dried for 5 minutes and were pulverized with mortar and pestle. After this process, 100 grams of pulverized bark was placed in a reagent bottle in which 250 ml of ethyl alcohol was poured afterwards. Lastly, extract which was rested for 10 hours for purification purpose was filtered through a funnel with filter paper. Varying the Amount of Bark Extract Amount of bark extract obtained through crude and ethanol extraction was varied for each treatment. 5 ml of extract was allotted to Treatment I, 10 ml for Treatment II, and 15 ml for Treatment III. Preparation of Jelly Form of Malunggay Bark Extract In a beaker, constant volume (5 ml) of water was poured and heated to 70oC. When water reaches the specified temperature, constant amount (10 g) of gelatin powder was added into the water. Then, the solution was continuously stirred. Before the solution solidifies, the assigned amount of extract per treatment was poured without stopping the stirring process. Material was immediately removed from heat. Measuring Voltage Zinc plate and carbon rod were installed to each treatment. From these electrodes, multitester was connected to measure voltage. Measurement was done for five times. Subsequently, voltage measured from each treatment was recorded. METHODOLOGICAL FLOWCHART CHAPTER IV RESULTS AND DISCUSSIONS The researchers conducted several experiments. Subsequently, data and results obtained from these experiments were recorded in tabulated from in this chapter. After each table of data, interpretations of these results were discussed. In the aid of these interpretations, the researchers could have initial assessment of the hypotheses presented in this paper. Table 2.0 shows that jelly form of extract from crude extraction yielded higher amount of voltage than jelly form of extract from ethanol extraction. However, more uniform voltage reading is obtained from jelly ethanol bark extract than jelly crude bark extract; as the amount of extract increases, amount of voltage reading increases. Table 3.0 shows that both form of crude bark extract generated relatively high amount of voltage. Even so, jelly crude bark extract yielded fluctuating amount of voltage as the amount of extract increases. Table 3.1 shows that as amount of liquid ethanol bark extract increases, amount of measured voltage decreases. For jelly form of bark extract from ethanol extraction, voltage reading increases, as the amount of said extract increases. CHAPTER V SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS Summary: This study entitled MOB Electricity: Malunggay Bark Extract as Alternative Source of Electricity aspires to prove if malunggay bark extract could be a possible source of electricity and to ascertain if there would be a significant difference when the method of extraction, form of extract, and amount of extract are varied. In order to test the feasibility of malunggay bark extract as alternative source of electricity, the researchers prepared two different set-ups and under each set-up there are three treatments. For the second set-up, amount of gelatin powder and amount of water used in each treatment were controlled. Then, voltage was measured in each treatment per set-up for five times using a multi-tester. The results obtained from different set-ups were analyzed using Two-Factor ANOVA with Replication. The results are summarized as follows: On the first set-up, statistical analysis showed that there is significant difference in the amount of voltage measured from liquid form of malunggay bark extract when method of extraction and amount of extract were varied. On the second set-up, statistical analysis showed that there is significant difference on the amount of voltage measured from jelly form of malunggay bark extract when obtained through different extraction method. Furthermore, statistically significant difference also exists on the amount of voltage reading when the amount of said form of extract was varied. Statistical analysis of Tables 3.0 and 3.1 indicate that there is significant difference on the amount of voltage measured when the form of extract and amount of extract were varied. Conclusion: Based on the results of statistical analysis and observations, the researchers conclude that malungggay bark extract could be a viable alternative source of electricity. Moreover, the people behind this study were able to discover that the 15 ml liquid form of extract obtained through crude extraction yielded the highest and most stable amount of voltage among all the treatments done. Recommendations: In this study the researchers encountered some hindrances which limited the scope of the investigation. Hence, only test for the feasibility of malunggay bark extract as an alternative source of electricity was conducted. Nonetheless, the study does not end with this objective. There are other factors related to electricity generation in malunggay bark extract that should be considered. Researchers would like to propose the following to other people who consider pursuing this project: Further increase volume of extract in order to obtain higher voltage reading. Convert the extract in a form that will facilitate easier and more stable voltage measurement. Subject the extract to chemical analysis to determine the component responsible for electricity generation. Develop a way to harness electricity from the extract.

Audio Linguaal in Study English

I. INTRODUCTION English is the most common foreign language that has been studied for all of student in our country. English has been learned since in elementary school until stand in University to get degree. In University, English become the common communication through the students. English uses in international communication, not only in oral form but also in written form. It has been known that student in school often get hard to understand English, they just know a little bit simple vocabulary and they are very lazy to practice it.Sometimes they do those things because they don’t have interest in studying English; they just study English in their school with old method and make them bored. Actually, they want to practice English but they not have capability on it, they just learn it but don’t understand, and do not know how to use it. Even in their school they have to be mastered the 4 skills in English; they just have capability in reading with their bad pronunci ations. Teacher must know exactly the condition of their student, and after that they have to do something to solve that problem.In this era, learning program not able to give satisfactory result. It is seen when the process of learning happen, the atmosphere seemed like the boring class. Teachers are busy to deliver the material without care to their students, are they understand the lesson or not. Most of teachers, always monotone and lack of variations they almost stuttering technology, are not able to use media in learning process. Teachers, consciously plan a systematic teaching activity by use all of things that can increase interest in study.Teacher must have creative idea to make their student better in English; on the contrary, they teach their student but their student never understand what they are studied. So they must find other way to teach their student and make them interested in study English. Actually, to know about student interest it is very easy, we must know wh at kind of method that can make them interested in the lesson. Sometimes they can ask the teacher to provide the new method in teaching and their teachers have to open their mind also aware what the students need in their learning process.Improved learning quality is one of the fundamental improvement in educations a whole, improve the quality of education be an integral part to improve the quality of people. Both aspects of ability, personality and responsibility as a human in the earth. Quality of education depends on the quality of the teachers and learning process. As a result, increasing quality in learning process is a fundamental issue for the improvement of the quality of education in a rational way. Sometimes, to make interesting lesson we can use media and teachers must know how to operate it. People in general are influenced by what is seen, in its feel and hear.In other words, it is not possible when there is a help in the learning process. The above statement can be sup ported by Munadi (2008), in his book that many states that helps the human senses in the acquisition of knowledge and experience is the sense of hearing and the sense of sight. Based in the explanation above, teachers must realize their position in learning process because they have big deal in the goal of learning. Author knows that in the process of learning student always take low participation and to make it high teacher must teach them in various way and make invention in teaching.If the student has interest in, there is a thirst for knowledge, learning becomes a pleasure, a pursuit, and a kind of enjoyment; if students lose interest in learning, then learning becomes the bitterest errand under the sun naturally positive achievement will not be desirable. When they are study, students can also learn about audio-visual aids and they are perfectly know how to use it. So when they are study or have their own presentation they can imitate their teacher and can make their own way to study. II. AUDIO-VISUAL A. AudioThe word â€Å"audio† is very familiar in our ear, because everyone knows that audio is a sound. We also know that Audio equipment is used for recording and reproducing sound. In daily life people always use audio to communicate or may other function from it. According to Rouse (2005), audio is sound within the acoustic range available to humans. Badan standar pendidikan nasional conclude that sound or audio is Sound is a wave of energy (vibration) that propagate through elastic media arrive at the ears and vibrate the eardrum, causing hearing process (2006).Audio media according to Sadiman (2005: 9) is a medium to convey the messages that have to be delivered in a symbol additive for, either verbal (spoken language) and non-verbal. The dictionary defines â€Å"audio† as â€Å"audible sound reproduced mechanically†. In Oxford Learners Pocket Dictionary (2008) the definition of audio is â€Å"hearing or sound†. We always he ar the word â€Å"audio† in our daily life. Sound from humans month (such as at time chatting, singing, laughing, and crying) (artikata. com, 2011). We also found the meaning of audio in pengertianmultimedia. nfo Voice or Sound is: a)Physical phenomena produced by the vibration of the object b)Vibration of an object in the form of analog signals with amplitudes that vary continuously with time From the explanation above, we can conclude that audio or sound is something that heard by humans and produced a vibration from the object, and causing hearing process in human body. Sometimes audio use to record and reproducing sound, when the sound produced it make a vibration in the air and directly through human’s ear. A. Visual Based on yourdictionary. om â€Å"Visual describes something that is seen† adjective (2012) and A visual is a film clip or image used to illustrate a story or a message noun (2012). According to the freedictionary. com visual is a picture, char t, or other presentation that appeals to the sense of sight, used in promotion or for illustration or narration. Often used in the plural:  an ad campaign with striking visuals; trying to capture a poem in a cinematic visual noun (2012) and as an adjective visual is something that Seen or able to be seen by the eye (2012). AudioEnglish. et stated that visual is â€Å"relating to or using sight and able is also one part of the learning activity. Where the activity of learning itself consists of: somatic (learning by moving and doing), auditory (learning by taking and listening), intellectual (leaning by problem solving and reflection), and visual (learn by seeing, observing and describing). Earns the fourth activity must be controlled so that learning can take place optimally. Based on Wikipedia (2012), â€Å"The visual system is the part of the central nervous system to be seen† (2012).Visual closely related to eye or vision. Which enables organisms to process visual detai l, as well as enabling several non-image forming photo response functions. It interprets information from visible light to build a representation of the surrounding world†. In Kamus Besar Bahasa Indonesia, â€Å"visual is visible to the sense of sight†. Hakim stated that, â€Å"Visual is a necessary condition for introducing a brand to the costumer†. But Olivia stated that â€Å"visual is one way of organizing thoughts and thinking skills and improve communication†.The definitions of visual have been found from many researcher and they elaborate that into several points: a)Visual is an important part in cultural dialog process ( Sachari ) b)Visual is the act of seeing ( Herwono ) c) Visual is a person who prefers to use vision in receiving information (Royan) d)Visual is to learn by observing and describing (Meier) Visual Media (Daryanto, 1993: 27), meaning that all props used in the process of learning that can be enjoyed through the eyes of the five sens es.Additional information from internet stated that â€Å"visual media is a tool or means communication that can be seen of sight (eyes)†. Visual combine art, typography, drawing, graphic design, illustration, and color in delivery process because visual contain of many important aspect. In conclusion, visual is all of things that can be seen by people and contain of many aspect like picture, videos, graphic and many else. Visual can be understood by message, because when people see something in their eyes, they can catch some new idea from the things that they look.Like a painting, someone can see what the meaning of the painting and can understand it by themself. From something visual people can learn about many things because they try to observing and describing the things that they saw (Meier). B. Audio-Visual In English dictionary for learners Collins (2003),† Audio-visual equipment and materials involve both recorded sound and pictures†. The same idea stated in Yourdictionary. com (2012), â€Å"an audiovisual is something that has components that appeal to both sight and hearing†.Also in Merriam-Webster Dictionary inform that â€Å"Audiovisual relating to, or involving both hearing and sight† (2012). â€Å"Audiovisual use both audible and visible†, The Free Oline dictionary by Farlex (2009). Based on Wordink. com, â€Å"audiovisual is relating to materials, such as films and tape recordings, that present information in audible and pictorial form:  a corporation's audio-visual department†. People use some equipment for audio visual, â€Å"Audio visual equipment can be any equipment that is used to engage the senses of sight and sound.Audio equipment may be used separately from visual equipment, but often they are used together† (ehow. com). Almost same information stated in Wikipedia (2012), â€Å"The term Audio-Visual (AV, or A/V) may refer to works with a sound and a visual component, the producti on or use of such works, or the equipment used to create and present such works†. Additionally, in AudioEnglish. com inform that â€Å"Involving both hearing and seeing (usually relating to teaching aids)† (2012). There are many experts that have idea about audio visual, such as: a. The combination of computer and video (Rosch,1996) . The combination of three element : sound, images, and text (McComick,1996) c. Combination at least two media input or output. Can be either audio ( voice and music), animations, video, text, graphics and images (Turban et al, 2002) d. Tool that can create dynamic and interactive presentations that combine text, graphics, animation, audio and video ( Robin;Linda, 2001) According to (Hermawan, 2007), â€Å"audio visual media is a modern instructional media that accordance with the time (the development of science and technology), included the media that can be seen and heard†.Almost same information, â€Å"audio visual is a modern in structional media in accordance with the times (the development of science and technology), that can be seen and heard† (Rohani, 1997: 97-98). From all of the explanation we can conclude that, audio visual is the using both of sight and sound. In audio visual have a media to support it, the equipment can be used in one time or separately. Many scientists also stated about audio visual, most of them have the same opinion about it. They think that audio visual is combination 2 media or 2 things that used to make an input or output, such as: video, animation, images or many else. III.LANGUAGE LEARNING A. Language Language  may refer either to the specifically  human  capacity for acquiring and using complex systems of  communication , or to a specific instance of such a system of complex communication (Wikipedia: 2012). In American Heritage Dictionary (2012) the definition of language is communication of thoughts and feelings through a system of arbitrary signals, such as voice sounds, gestures, or written symbols. Based on Dictionary. com â€Å"Language is a body of word and the systems for their use common to a people who are of the same community or nation, the same geographical area, or the same culture tradition† (2010).Besides that, another expert (Albert Einstein) stated that Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone. According to Ensiklopedia of Britania (2012) Language is a system of conventional spoken or written symbols by means of which  human beings, as members of a  social group  and participants in its  culture, express themselves. The functions of language include  communication, the expression of identity, play, imaginative expression, and emotional  release. Additionally, there are many expert stated about language.Such as: a) Bill Adams Language is a system of individual psychological development in a context of inte r-subjective b) Wittgenstein Language is a form of thinking that can be understood in touch with reality, and has the logical form and subject c) Ferdinand de Saussure Language is the most differences between people because with language people can differentiate their self to others. d) Plato Language is the essentially a statement of one’s mind trough the medium of oomata (names of something) and rhemata (speech) which is a mirror of their idea e) Bloch ; TragerLanguage is a system of symbols that are arbitrary and the system is social group working together Language used in humans life, they used it for communication. Language can be known by rule or systems. As Owen  in Stiawan  (2006:1) stated language can be defined as socially shared combinations of those symbols and rule governed combinations of those symbols. Same with information before, Mackey (1986:12) said language may be form and not matter. Thus, language is something that people use to communicate with othe rs. Sometimes known by a rule or system and also thinking of people in daily ife. Language can be spoken or written and there are many others type of language. It also known by the most fundamental ideas in science. B. Learning Based on Wikipedia (2012) Learning is acquiring new, or modifying existing, knowledge, behaviors, skills, values, or preferences and may involve synthesizing different types of information. In learning process we heard about new information and we reinterpretation it in our life, like Ramsden (1992: 26) said that Learning involves comprehending the world by reinterpreting knowledge.According to Winkel, Learning is all mental or psychic activity that takes place in an active interaction in the environment, which produces changes in the management of the understanding. Another opinion comes from Ernest R. Hilgard in (Sumardi Suryabrata, 1984:252) learning is a process that was done intentionally, which then caused the change, which was different from the change s brought about by others. Same information comes from Gayne, in his book (The Conditions of Learning, 1977) a similar study demonstrated changes in behavior change and support by idea from Moh.Surya (1981:32), the definition of learning is a process of individual efforts to acquire a new behavior change overall, as a result of the individual's own experience in interacting with the environment. Thursan Hakim (2005:1), learning is a process of human personality changes, and the changes of revealed in the form of increased quality and quantity of behavior such as increased skills, knowledge, attitudes, habits, understanding, skills, intellect, and so other capabilities.Slameto (2003:13) believes that, learning is a process of one's efforts to acquire a new behavior changes as a whole, as a result of his own experience in interaction with their environment. While other expert Skinner in Dimyati and Mudjiono (1999:9), learning is the relationship between stimulus and responses are crea ted through a process of behavior. Many experts found the definition by themselves by done he research, and here are their opinions: a.Learning may be defined as the process by which behavior originates or is altered through training or experience. † (Whittaker, 1970:15). b. †Learning is shown by change in behavior as a result of experience. † (Cronbach, 1954:47) c. Learning is the process by which behavior (in the broader sense) is originated or changed through practice or training. † (Kingsley, 1957:12) d. Witherington (1952): â€Å"learning is a change in personality that is manifested as patterns of response that a new form of skills, attitudes, habits, knowledge and skills†. e.Hilgard (1962): â€Å"learning is the process by which an emerging behavior or behavior change due to appear in response to something the situation† From all the explanation, can be concluded that all mental or psychic activity that done by people can cause changes of behavior before and after learning. So learning process make many changes in personal life, not only behavior, manner, knowledge, but also all of things that connect with humans every individual. C. Language Learning Based on sil. org (2012) a language learning method is an overall plan for learning a second language, based on the theoretical  approach  selected.It involves the design of a syllabus for the course, which in turn consists of learning objectives and  techniques  for achieving those objectives. But another opinion comes from eu. wiley. com state that (2012) Language learning  is a scientific journal dedicated to the understanding of language learning broadly defined. It publishes research articles that systematically apply methods of inquiry from disciplines including psychology, linguistics, cognitive science, educational inquiry, neuroscience, ethnography, sociolinguistics, sociology, and anthropology.Language learning based on cognitivealtas. org (2012) la nguage learning is the process by which humans acquire the capacity to perceive, produce and use words to understand and communicate, this capacity involves the picking up of diverse capacities including syntax, phonetics, and an extensive vocabulary, the language might be vocal as with speech or manual as in sign. But according to Scribd. com (2012) language learning is an obligation for all those who want to â€Å"conquer† the world. Language today becomes a culture that should be preserved existence.By learning a language means also learned to cultivate them, develop them, make them change into a great people. Actually, people studied about foreign language and they study it in school and other place. There are some opinion about foreign language learning based on expert, those are: 1. Thomson (1993) â€Å"The process of learning a foreign language is extremely difficult, but at the same time, surprisingly easy. When I think about the difficulties of it, I am amazed that someone can actually do it at all. Fortunately, all the difficulties of this process are in your sub-conscience and you don't even know about them.The objective then becomes to steer the sub-conscience in the right direction. Then and only then does learning to speak a foreign language become simple! † 2. Robert W. Blair (Creator of the Power-Glide Method) â€Å"With few exceptions, language-learning methods have not changed much in the past 50 years. What you typically find today is the old ‘listen-and-repeat' methods done with new technology: tapes, CDs, computers, etc. , packaged and worded to make them seem new. But they usually aren't new at all. They are the same old ‘uglies' of language learning repackaged to look new.The essence hasn't changed. † 3. Ivan R. Dihoff (Professor of Language and Linguistics) â€Å"In short I am very impressed by the thoughtful and insightful work that Dr. Zilberman has placed in these important language teaching material s. He and I have discussed at length how his materials would function in self-instruction as different from the classroom. My conclusion is that they are perfect for self-instruction, and would work extremely well in the classroom once the instructor is trained and learns to use them as adjunct to classroom conversations in the language. In conclusion, language learning is the process of producing and receiving information about language, included word, linguistic, and syntax. From language learning people can communicate with other people and study how to write or speak correctly. In language learning, use a syllabus of course that consists of learning objectives and  techniques  of receiving information process. IV. DISCUSSION Audio-visual is fundamental things in our life, with audio visual we can communicate with other people and also make something interesting that can be seen and learned by other people.Without audio-visual, learning process can be monotone and not interes ting enough for student. When they are study with old style, they cannot catch the lesson directly and easily, sometimes they must study it by themself in their own house. The using of audio-visual in learning need some media to support it, almost all of the media are the electronic tools and need new technology to make it more interesting and more update. New technologies provide the means to help reshape both the content and processes of language education.As seen from the above three case studies, appropriate use of new technologies allows for a more thorough integration of language, content, and culture than ever before and provides students with unprecedented opportunities for autonomous learning. Computer technologies not only help teachers and students to transcend linguistic, geographical, and time barriers but also to build bridges between bilingual, ESL, and foreign language programs. The use of new technologies allows students to engage in the types of online communicatio n and research which will be paramount for success in their academic and professional pursuits.Nowadays, students very like to playing games, watching movie or many else. They like that because all of that have interesting part in their packaging, like film and game it give us interesting site with the visualization and the sound or audio. Picture can make them have their own imagination and sometimes we can add funny pictures and can make them focus on the lesson. Audio and visual make they left brain work and increase their study attention, left brain studying is more effective because they can remember the lesson in a long time.Visual also give student some adrenaline to analyze what they are seen the visual media that given by their teacher. In this case, teacher in the modern era, have to know how to use audio-visual aids to support their lesson. Sometimes teacher just know about Microsoft word, all of us know that this kind of software just used to make a text and from some re search that students rarely like to read the text because they just feel sleepy and do not want to recall back to their old lesson.Teacher is the people that have the biggest influence to their students, because children get more lessons from them than their home. The key to successful use of technology in language teaching is our human capacity as teachers to plan, design, and implement effective educational activity. Language learning is an act of creativity, imagination, exploration, expression, construction, and profound social and cultural collaboration. If teacher use computers to fully humanize and enhance this act, rather than to try to automate it, they can help bring out the best that human and machines have to offer.Studied by using audio visual have a lot of benefits, because the use of audio visual can gain more experience, impressive, more clear and concrete. Besides audio-visual media have the potential subject according idger dale as follows (Ali Pandie: 1984): a. Pr ovide concrete foundations for thinking a. Make lessons more interesting b. Allow a longer lasting learning outcomes c. Provide real experiences d. Develop the regularity and continuity of thought e. Can provide experiences that are not acquired any other way to make learning more efficient and diverse depth. . Audio visual media can be repeated Some studies have shown that learning is absorbed through the medium of vision (visual media), as well as the auditory (audio media), can accelerate the absorption of learners in understanding the lessons presented. One of the advantages of learning the use of audio visual media is looks can be made as attractive as possible, so that children are interested to learn. For example, the animation – animated cartoon about a living creature in the forest that can be directly liked by students or children.Audio-visual aids in the classroom can enhance teaching methods and improve student comprehension. Today's technology offers many choices to the informed educator who wishes to capitalize on a new generation's appetite for multimedia presentations. Lesson plans that incorporate the use of audio-visual aids should be consistent with curriculum objectives and not segued improperly. Audio-visual in language learning also have the disadvantages, those are: 1. Forced stressed the importance of the material rather than the process of development and still looked upon as an audio-visual aids in teaching teachers. 2.Too much emphasis on the mastery of the material of the development process and still looked upon as audio visual aids teachers in the learning process. Have orientation in the real media. 3. Audio-visual media tend to use one-way communication model. 4. Audio-visual media cannot be used anywhere and anytime, because audio-visual media tend to remain in place Thus, audio visual system in language learning especially English is really needed because trough audio visual student can learn something by themselves eas ily. This kind of method can make student pay more attention to the lesson and they can analyze all of things in their lesson.There are so many advantages in audio visual learning that can help student and teacher in the learning process. On the contrary, there are a few of disadvantages of audio visual learning, most of them just have technique program, such as cost, tools, and also the maintain of the tools. This method also has a problem in the way of learning but it just a piece of cake to repair it. The significant problem of audio visual learning is not serious enough; it can solve and covered by all of the benefits of the method. V. CONCLUSION A. ConclusionLearning English in school is quite hard because student cannot pay attention to the lesson, they thinks that the lesson is seems boring and make them cannot catch the idea of what the teacher explain before. With this condition, teacher as a people who have more influenced to the student need to know the media that can imp rove their student interested in study. They can use audio visual media as a teaching media, because with audio visual their student can be more attractive and interested with the lesson. Student very crazy about movie, game or other media lately, and this entire media connected to their audio and visual.If the teachers use this media, student can catch the material easily with their own understanding. They are very imaginative, so when the teacher teach them with what they are like and understand about, they can memorized it every time. Audio visual media help student in learning process because this media have a sound, color, picture or many else that can balanced their brain. Picture and many interesting things that student like is connect to the left brain studying, because when student study with left brain style their lesson can be memorable.Language learning is an act of creativity, imagination, exploration, expression, construction, and profound social and cultural collabora tion. If the tecaher use audio-visual to fully humanize and enhance this act, rather than to try to automate it, they can help bring out the best that human and machines have to offer. C. Suggestion Learning process is quite difficult for students, teacher must be respected to their student and give the interesting lesson. so that, they can accept the lesson directly. Teachers have to up to date about technology, because technology very useful in language learning.Many technologies can be operated by teacher easily if they understand how to use it. Teacher have to change their teaching style become more interesting to increase their student interest to the lesson, teachers can follow the computer course or other creativity course to find the way to make the lesson memorable. The teacher must to do the best for the student because succeed of student is come from the teacher. BIBLIOGRAPHY Atoel, Roby. Media Audio Visual. Blogger, 10 May. 2011.

Conversation Analysis

Conversation Analysis Conversation is absolutely instilled throughout every corner of every day for the totality of our lives. Whether it is on your favorite morning talk show, a casual encounter with a roommate, or admitting an undying love to your significant other, our lives, along with our realities, are entirely shaped by the conversations we allow ourselves to become continually engulfed in.With so much of our daily lives revolving around the conversations in which we are a part of it becomes clear that the underlining meanings, or messages, of these conversations could very well be the motor that keeps our realities in a state of progress. Conversation is interactional, philosophical, emotional, and entirely necessary in order to fulfill and express any type of accomplishment. When these conversations, these parts of our lives, are put under a trained mental microscope with the motive of finding a better understanding of the interaction taking place, it is referred to as Conve rsation Analysis (CA).Conversation Analysis’ method is aimed at determining the methods and resources that the interactional participants use and rely on to produce interactional contributions while also making sense of the contributions of others (Schegloff, 2007). What follows in this essay is an in-depth look at the practices and methods of Conversation Analysis showing that a better understanding of one’s conversation(s) will ultimately lead to a better understanding of one’s reality; while also showing that every utterance fulfilling some kind of act, or task, and is entirely motive driven toward the accomplishment of one of these tasks.Conversation Analysis is the study of social interaction, embracing both verbal and non-verbal cues and conduct. As a field of study, Conversation Analysis was developed in the late 1960’s by Sociologist Harvey Sacks with the help of his associates Emanuel Schegloff and Gail Jefferson. Harvey Sacks is commonly regarde d to as the ‘father’ of the particular study. Conversation Analysis is frequently embodied into the works of sociology, anthropology, linguistics, speech communication, and psychology just to name a few.Although similar, Conversation Analysis differs from Discourse Analysis because its focus is squarely on the processes involved in social interaction, and does not include the work of written texts (Sidnell, 2010). To create an accurate analysis of conversation the interaction should not be viewed from a far or from a perspective that is external to the participants own reasoning and understanding of their circumstances and communication (Sidnell & Stivers, 2012).The analysis in which we are going to use as an example for the remainder of the essay focuses primarily on the functions of turn taking, adjacency pairs, repair, and speech acts; all common perspectives in the field of Conversation Analysis. The format of a conversation can be relatively easy to understand; one party communicates, the remaining parties respond in somewhat of a positive feedback loop; meaning that the feedback loop of the conversational system is continually going around with the addition of new information and new utterances, thus a positive feedback loop.This way of conversation is simply called ‘turn-taking’ implying that it is not a lecture style of communication with primarily one party conducting the conversation, rather an interaction where one party’s conversation is influenced and working together with a separate party’s. After establishing the turn taking method of conversation we are able to take it one step deeper and analyze the chosen utterances. While turn taking the two parties will be exchanging what are called ‘adjacency pairs;’ adjacency pairs are composed of two utterances, one after the other.The first pair provokes a response from the second party, such as: ‘Hello, how are you? † could provoke a resp onse such as: â€Å"Fine, how are you? † That is an adjacency pair. When the conversation fails to provide a relevant response to the pair; for example: If â€Å"Hello, how are you? † were to be responded to with â€Å"My favorite color is purple. † The responder has failed to provide a relevant response and has done what is considered to be a breach of conversational maxim, or the maximum of relevance. If such a breach were to happen one can resort to what is called ‘Repair. Repair is a self-righting mechanism that describes how parties in conversation deal with problems in speaking, hearing, or understanding. If the previous example of â€Å"My favorite color is purple† was said due to a misinterpretation of the required response to repair the conversation they might immediately say, â€Å"Oh, I’m terribly sorry I must have misheard you, I’m doing well how are you? † Lastly, this essay will focus on what are called ‘Spee ch Acts;’ the main goal of the utterance, the underlining message of the conversation.For example, telling someone that you will meet them at 7:00 is creating a commitment, a promise, making an arrangement; it isn’t simply just words pieced together. Speech acts include promising, ordering, responding, greeting, warning, inviting, asking, congratulating, etc. , and are the task in which the conversation is attempting to achieve. These perspectives of conversation analysis are just a few of the many factors that go into the structuring and fulfillment of a successful conversation.Turn taking is one of the easier factors of conversation analysis to point out to one who has yet to gain much experience in the field of communications. In the following transcript T is asking E why he has set up his laptop to record what they are talking about: [0:00 – 0:30] T: Takin’ pics? E: No. I’m just recording what we’re saying. T: Does it matter what we say? E: No, doesn’t matter. T: We can say whatever the f*ck we want? E: Uh-[huh] T: [just like that? ]E: Yeah, haha, we don’t even have to be, like, talking the whole time, just has to be 20 minutes worth of time. T: Soo what is this for? E: I get extra credit for my communications class T: you just get conversation from us? E: uh-huh! haha T: What’s up Commi’s?! This is an example of turn taking because T is not lecturing E about something, he is seeking information from E that is relevant to the conversation, and relevant to T’s reality. The two conversers are using adjacency pairs while speaking to each other in order to keep the onversation flowing in a positive feedback loop, while also not breaching the maxim of relevance. The conversation holds adjacency pairs because the utterances from the two conversing follow one another, and anything E said would not be relevant to the reality of T without T first asking E what was going on with the laptop. T had an underlining task of seeking information through his conversation; he successfully used a Speech Act in order to gain the information in which he sought, thus having a clearer understanding of his reality at the time of the conversation.Repair comes into a conversation when the feedback loop of those conversing becomes skewed; a misunderstanding of an utterance from one party to another can alter the outcome and flow of the conversation until the party that misunderstood an utterance and altered the feedback of the conversation has done repair work to reposition the conversation back into a positive feedback loop. The example in the transcript comes into play when E walks into T and J’s room when J is trying to study.E realizes that his presence in the conversation that T and J were having about the material they were studying is beginning to interrupt the flow of their conversation. E begins his repair work to the conversation: [12:00-13:47] J: I’m going to g o study T: good old study sesh J: You can leave that in our room if you want, while we study haha E: I’ll walk back and fourth (p 3. 0) Did you end up selling those clubs dude? T: Yeah, Yogi bought them E: Dam[n] T: [It would] have been a good deal E: (p 8. 0] Connor how was your day?C: Sick! I did a lot of studying. Now I’m helping out with some extra credit J: Excellent! E: Your day was excellent Jack? J: No! my day was pretty shitty, shitty. E: haha (p 7. 0) You want this door closed? J: Yeah, thanks. E: alright sorry guys, peace J: Give him an A! E: I need an A! haha bye guys Once E realizes that his two roommates, T and J, are studying and that he has interrupted their concentration with the video on the lap top he begins to start the repair process of the conversation, and his present reality.E realizes that he shouldn’t be intruding on T and J and by uttering ‘Do you guys want this door closed† he is implying that the interruption is understoo d and he is going to repair the situation by leaving them alone and closing the door on his way out. The repair work is understood by J and he thanks E for the notion and sends him off by telling the camera that E should get an A for his extra credit work that was mentioned in the previous transcription.Repair work is vital to a misunderstanding in a conversation, if a situation arises where repair work is needed but goes unnoticed, the misunderstanding of the conversation will lead to a further misunderstanding of the present reality. Speech acts are the underlining meanings of our conversation; they are the tasks in which we are trying to fulfill through our interaction. Speech acts can be broken down into three categories: locutionary, illocutionary, and perlocutionary acts.Locutionary is the actual utterance and its phonetic meaning, ilocutionary is its intended significance, and perlocutionary is the actual effect on the conversation and present reality. In the following transc ript E goes back into T and J’s room to try and find information about golf clubs. He is not just trying to strike up a conversation; he is seeking information and is attempting to accomplish a task: [16:47 – 19:30] E: Jack do you have any old golf clubs? J: Naah, only the ones I use. E: Does Nick? J: Nope. E: fuckT: John has old ones, but they’re pretty nice. And I don’t think, I can [ask him] E:[Yeah, if he’s looking to sell them] E: definitely let me know, ‘cause I’m trying to go. T: If he does I can definitely let you know. E: awesome thanks, I’m trying to go. The locutionary meaning of E’s utterance is easy to understand; he is seeking a way to buy golf clubs from his roommates if they happen to have an old set. The illocutionary in this particular example matches the meaning of the locutionary as its intended significance is to find some new golf clubs.The actual effect on the conversation, the perlocutionary act, c auses J and T to respond to E with their answers, as it would be in their better interest to sell some old golf clubs. E uses speech acts to try and acquire the information in which he sought. The topic of golf clubs did not just happen to come up in conversation, but was purposely brought into the realities of T and J by E through E’s search for information. Speech acts revolve around every conversation and interaction taking place throughout our lives.Even in random day-to-day gossip speech acts are the motor that drive these interactions in a forward motion of gaining new information. When one better understands the underlining meanings of the conversations throughout their day there is no doubt that that better understanding of communication leads directly to a better understanding of one’s reality. Our realities are entirely shaped by and understood through the words in which we use to describe them.The motives behind our interactions are what shapes the conversat ions into what they become; whether we are trying to be humorous and crack a joke, give a serious speech, show empathy toward someone, argue our opinions back and fourth, or seeking information these certain motives are what craft our interactions with one another. When one better understands these motives they will better understand their conversation, have a better understanding of how to accomplish tasks through their conversation, and ultimately lead to a better understanding of one’s present reality.

The Red Cross And Home Fire Prevention Campaign - 915 Words

The Red Cross in Hawaii responds to disasters every four days. More than 90 percent of them are fire-related. The American Red Cross home fire prevention campaign aims to reduce the number of fire deaths and injuries in the U.S. by 25 percent within five years. This is done by educating people about the risk of home fires and by installing free smoke alarms in their homes. â€Å"Since we are responding to fires after they happen, putting a lot of resources to respond to fires before they happen is a much better use of resources, Preparedness Manager Disaster Services with the Hawaii State Chapter Carole Kaapu said. Smoke alarms cut the risk of death from fire in half. â€Å"The fatalities are preventable. It s just like why is it important to have seat belts in your car? Not everybody is going to have an accident, but because they have seat belts, people s lives are saved. The smoke alarms are probably not gonna save your house. It s not gonna save the belongings in your house, but it will save the lives of the people in the house,† Kaapu said. Nationwide the program is for seniors (anyone older than 65), any home with children younger than 17, anybody who is from a low income area, a targeted area – meaning that there has been fires in that neighborhood – and native population. â€Å"Those five things are 95 percent of the state of Hawaii. So for us it s easier to say seniors because they are used to self identifying.
