part of the paper will be dedicated to introducing the rationale for the study, the aims and objectives of the study as well as the research questions It will also present the scope of the study, method of the study and the design of the whole study Statement of the Problems and Rationale of the Study Vocabulary has a significant position in the process of mastering a language Linguists and researchers quotes Wilkin, D (1972:10): “Without grammar, very little can be conveyed, without vocabulary, nothing can be conveyed” as the affirmation of the role of vocabulary Within the current English teaching context in Vietnamese schools in the recent years, teachers and students are getting more complete awareness of the important role of vocabulary Therefore, they started to pay greater attention to vocabulary development Teachers have applied many teaching approaches, methods and techniques to improve the students‟ vocabulary acquisition The efforts from both teachers and students have made certain progress As a high school English teacher, I am especially interested in developing students‟ vocabulary Having had several years of experience in teaching English to the students gifted in science at Hanoi – Amsterdam high school, I am concerned a lot about the needs to improve their vocabulary on science and technology In my points of view, the number of reasons that makes it necessary to improve the students‟ vocabulary on science and technology can be divided into external and internal ones External reasons - There is no specific English textbook for the science gifted students at high school level all over the country - At Hanoi-Amsterdam high school, the textbook “Tiếng Anh 10” issued by the MOET is used to teach all students including science gifted students This is a compulsory course TIEU LUAN MOI download : skknchat@gmail.com -2- book of general English for all students in the country, so not much knowledge and English vocabulary for specific purposes such as science and technology can be found in it Internal reasons - Almost all students at Hanoi-Amsterdam high school have equipped themselves with good basic practical general English knowledge Many of them started learning English from the primary school or even earlier In order to be able to enroll to this school, they had to gain high marks at the entrance examinations including their majoring subjects, Maths, Vietnamese and English That is why for them, the “Tiếng Anh 10” is rather simple Beside the textbook and workbook, students are regularly given supplementary and intensive exercises compiled by their classroom teachers - However, from my observations, the vocabulary, especially the vocabulary on science and technology had been undervalued in comparison with grammar in the previous years of their basic high school Many students have difficulties in expressing their own ideas because of the vocabulary deficiency Most students are unfamiliar to the vocabulary on science and technology, as well as English scientific literature - In results, when students want to extract useful information related to their field in English, or have chance to attend the international examinations, camps or workshops on science and technology, the students often face with the lexical gaps and this significantly affects their progress and active participation - In fact, many students have realized the vital role of English vocabulary on science and technology for their future study as well as carrier They devote a great deal of time to building up this kind of vocabulary In the process of trying different vocabulary teaching strategies and techniques, I found that reading is a suitable way for students to enhance their vocabulary on science and technology The advantage of learning and developing vocabulary through reading is that students can understand word meaning in the concrete context The idea of testing the TIEU LUAN MOI download : skknchat@gmail.com -3- supplementary readings as a means of improving their students‟ vocabulary came to my mind It became an impulse for me to a study on the impact of supplementary reading on the development of English vocabulary on science and technology in grade 10 classes for the science gifted students In terms of students‟ benefits, this program will provide opportunities for students to develop their vocabulary and get ready for further reading in their future specialty Aims and Objectives of the Study This study is firstly aimed at investigating the students‟ needs to develop English vocabulary on science and technology Secondly, it is aimed to experiment the impacts of supplementary reading program on the development of grade 10 students‟ vocabulary on science and technology The main objectives in this study are as follows: - To identify students‟ perceptions of the need to develop their English vocabulary on science and technology and their willingness to spend time on supplementary reading program - To introduce the supplementary reading program and examine its effects on grade 10 students‟ English vocabulary acquisition - To share the findings with teachers and students who are interested in this field of English vocabulary teaching - To make some recommendations for further study Research Questions In order to achieve the above-mentioned aims and objectives, the answers to the following research questions are needed to be found What are the students’ perceptions of the need to develop their English vocabulary on science and technology? TIEU LUAN MOI download : skknchat@gmail.com -4- To what extent are the students willing to take part in the supplementary readings? Is there a relationship between supplementary reading and the development of English vocabulary on science and technology? Scope of the Study Given the time constrain, the study was conducted on the grade 10 students in two classes gifted in science only Taking into account that the participants are only beginners of science and technology aspects, the vocabulary given through reading passages is mainly English for General Science Method of the Study To find out the answers to the above research questions, a quasi-experiment design has been adopted - The pre-experiment questionnaire was applied as an instrument to investigate what students think of the need to develop their English vocabulary on science and technology and how they are willing to take up the additional readings - The pretest and posttest were conducted with 60 students divided into two randomly selected groups to measure the differences in students‟ vocabulary acquisition Design of the Study The study is divided into three parts as follows: Part one presents an overview of the study in which the rationale for the research, the aims and objectives, the research questions, the scope of the study, the research method as well as the design of the study were briefly mentioned TIEU LUAN MOI download :

make it get harder to choose healthy food over time Juanmonino/iStockphoto It sounds like a science experiment designed by Willy Wonka: Take a lot of junk food, feed it to some rats, and see what happens Scientist Paul Johnson of the Scripps Research Institute and his team did just that But their science experiment was no fiction They had a serious goal: to try to understand how parts of the brain play a role in obesity (Obesity is the condition of being very overweight, which has been linked to a variety of health problems.) The scientists observed that the more junk food the rats ate, the more they wanted to eat—a behavior very similar to that of rats addicted to heroin, a dangerous drug Johnson told Science News the experiment shows that the brain chemistry of obesity and drug addiction may be quite similar In their experiment, Johnson and his team studied the ―pleasure center‖ of rats’ brains The pleasure center is a complicated network of nerve cells Together, these cells work as the body’s reward system If the animal exercises or eats, the cells reward the animal by TIEU LUAN MOI download : skknchat@gmail.com -XIV- releasing chemicals into the body that make it feel good And when the body feels good, the animal—or person—will want to the behavior again Pleasure centers can release these chemicals in less healthy ways, too Drugs like heroin can cause the pleasurable chemicals to be released For the experiment, Johnson fed foods like cheesecake, bacon and Ho Hos to one group of rats These foods are all high in calories and high in fat Another group of rats received a regular, nutritious diet The rats that ate junk food started to eat more and more ―They’re taking in twice the amount of calories as the control rats,‖ says Paul Kenny, also at Scripps Research Institute Kenny worked with Johnson on the study Kenny and Johnson wanted to know what was going on in the brains of rats that were overeating To find out, they came up with a simple reward system They first devised a way to deliver a small electrical charge to the rats’ brains This electrical charge would stimulate the pleasure centers to release pleasure-causing chemicals The rats could control how much stimulation—and how much pleasure—they received by running on a wheel The more the rat ran, the more pleasure it received The rats that had been eating junk food started running more and more This behavior suggested that the junk-food–eating rats needed more brain stimulation to feel good compared with rats on a normal diet In other words, their pleasure centers were becoming less sensitive and the junk food didn’t make them feel good unless they ate more and more The same process happens in the brains of drug addicts As the pleasure center becomes numb, the addict has to consume more of the drug to feel good ―They lose control,‖ Kenny says ―This is the hallmark of addiction.‖ Kenny and Johnson also found out that the effects are hard to reverse After they took away the junk food and offered the rats a nutritious diet, the fat rats refused to eat ―They starve themselves for two weeks afterward,‖ Kenny says Experiments like this one could help scientists understand how chemicals in the brain contribute to obesity With that information, they may be able to help people avoid obesity—and all of its health problems—in the first place Not bad for a bunch of rats with Ho Ho’s in their paws TIEU LUAN MOI download : skknchat@gmail.com -XV- WORKSHEET List 5-10 kinds of junk food Number is done for you Bacon 10 Give the Vietnamese meaning of the following words in the text Find the adjective or verb forms of these words (Look at dictionary if necessary) Word Meaning Vietnamese in Adjective form Verb form Experiment Obesity Observation Pleasure Addiction Variety Release Stimulation Find more words with over- prefix (for example: Overweight) ……………………………………………………………………………………………… ……………………………………………………………………………………………… What did the scientists find when observing the junk-food-eating rats?
