significance of the study, the research questions, the scope of the study, the methods used in the study and the organization of the study Rationale for the study Due to the current status of English as a global language of science, technology, and international relations, Vietnam considers the teaching of English a major educational priority Teachers of English have made great efforts to make use of the multimedia technology and to integrate this technology in their classroom teaching to improve their English language teaching Applying Information Technology (IT) into teaching and learning is one of the essential tasks of the National Education Service at present IT application to English as a second language (ESL) teaching is, therefore, a need and the most important one to make the more effectiveness The advantages of using the technology-assisted teaching in the language classroom have been recognized by many researchers in applied linguistics The main one is considered to be its ability to present and immerse learners into complete communicative situations (Lonergan, 1984) According to Hutchen (2004), the use of technology-assisted instruction is widely applied in education to improve student performance, learning and satisfaction Another advantage is the ability of the technologyassisted teaching to cover non-verbal aspects of communication and its cross-cultural comparison potential (Stempleski & Tomalin, 1990) In addition, using IT tools in the classroom allows differentiation of teaching and learning according to students‟ abilities, learning styles and personalities To teach English more effectively, teachers and students need to approach various types of IT tools such as computers, overhead-projectors, multimedia projectors and some popular softwares in teaching as: Power point, Word processor,Window media The powerful IT tools, which can help teachers to expand the four walls of the tradditional classroom and rebuild the class with many useful controlled and free activities for communicative competence, are increasing in both quality and quantity I myself enjoy teaching English, especially teaching listening skill with the help of IT tools and I find that students are interested in the lessons with the application of IT I have also tried using the technology-assisted teaching for the teaching of listening skill and found it rather promising However, there have still been some questions such as how much does the technology-assisted teaching actually motivate students to learn? To what extent does it affect students‟ listening comprehension in classroom? How should the technology-assisted teaching be used in listening lessons to improve students‟ listening comprehension? These questions motivated me to carry out the study on “The effect of technologyassisted teaching on 10th form students’ listening comprehension” With this study, the researcher mainly focused on carrying out a quasi-experimental research to investigate the effectiveness of using the technology-assisted teaching on improving students‟ listening competence The technology-assisted teaching or IT tools, which are mentioned in this study, are computers, Multimedia Projectors to show the Powerpoint presentations In applying IT, almost teachers in the author‟s school context understand IT as the use of PowerPoint, which is introduced to them in the course of applying IT in foreign language teaching Objectives and significance of the study The first and foremost aim of the study is to find out the effects of technology-assisted teaching on improving the students‟ performance in English listening skill, so as to change their attitude to listening as well as to enhance the students‟ participation in English listening classes of the 10th form students at Ngoc Hoi High School (NHHS) The second one is to discover the benefits of technology-assisted teaching that students perceive in listening comprehension Last but not least important, some effective ways for teaching listening comprehension are recommended with a view to improve students‟ listening comprehension The study is done in a hope that it will help better the situation of teaching and learning English listening comprehension at NHHS Thus, it will help enhance students‟ English competence Research questions To achieve the aims which are mentioned above, this study was designed to test the following hypothesis: - Hypothesis: Technology-assisted teaching helps to improve students‟ listening comprehension In order to draw the conclusion on how hypothesis would be accepted, the following research questions are raised: 1, To what extent does technology- assisted teaching help to improve students’ listening comprehension as measured by the difference between their pretest and posttest scores ? 2, How much students perceive the benefits of technology- assisted teaching to their listening comprehension ? It is hoped that the findings of the study will be of benefit to the teachers at NHHS, especially those who are engaged in teaching listening The study can highlight some effects that technology- assisted teaching can bring about to improve students‟ listening comprehension and some benefits of technology- assisted teaching that students perceive in listening comprehension The findings of the study will also contribute to our understanding of the role of technology in language teaching and learning in general Scope of the study The research limits its scope to the teaching of listening skill in English using the regular English text book 10 and to its participants of 10th form students at NHHS The choice of participants is simply a matter of convenience the researcher is teaching listening for 10th form students at NHHS In this study, the term “technology” is used in a very narrow sense In fact, „technology‟ in this study refers to the use of the Powerpoint as a support to the teaching and learning of listening comprehension in the researcher‟s school She is fully aware that technology is not synonymous with the Powerpoint, but she decided to use the term in this restricted sense because this is a common way that technology is meant in her context Method of the study To realize the objectives of the study , the main research method employed in this study is a quasi- experimental design which according to Seliger and Shohamy (1989:136) involves the three basic components of experiments: the population (the 10th form students at NHHS), the treatment (Technology-assisted teaching) and the measurement of the treatment (t-test) The data for the study were obtained through the following instruments: XVIII - Receive the Handout - => Leads in the new lesson: Cuc Phuong National Park Discussion: -Ask Ss to work in groups and ask and answer questions - Shows questions on the screen 1.where is Cuc Puong National Park?
