Dinh University of Technology Education EGP: English for General Purposes ESP: English for Specific Purposes z CHAPTER 1: INTRODUCTION 1.1 Rationale Learning English in Vietnam today is quite popular and its popularity is increasing day by day This is due to the fact that Vietnam has recently adopted an open-door policy which encourages broadening and improving its relationship and cooperation with other countries in many aspects of life such as diplomatic, economic, cultural, scientific and technological areas English is not only a means but also a key to gaining access to latest scientific and technological achievements for a developing country like Vietnam, where modern science and technology is badly needed Recognizing the necessity of this global language, most of the schools, colleges and universities in Vietnam consider English as the main, compulsory subjects that students must learn In the English language learning and teaching process, evaluating a test is significant Test is a part of teaching and learning process because it also provides feedback about the achievement of teaching and learning objectives for those who are involved in the education system Moreover, the use and necessity of knowing a person’s language ability is through a language test In education, especially at the Faculty of Foreign Languages at Nam Dinh University of Technology Education (NUTE), testing the students’ achievement toward teaching objectives is needed Without an achievement test, it is difficult to see how rational educational decisions can be made NUTE is a technological university and students’ learning English ability is really low Evaluating a test is also one of the methods to improve students’ learning process and results Although there were many theses mentioned this problem but at NUTE it is still new and very necessary because how to evaluate the test after each semester still receives little attention and up to now the process of test analysis after each examination hasn’t been fully investigated Consequently, students’ results are getting worse and worse As a teacher myself, I see that we, teachers at NUTE, just stop at experienced level of test making procedure, test administration, test marking procedure during and after examination We not care testing evaluation from other teachers and students, so the results of test are not still improved z Moreover, test’s validity can be seen as an attempt for improving the test quality Being a measure of students’ achievement toward learning objectives, final examinations must be valid Validity is one of the characteristics of a qualified test Therefore, “Evaluating the validity of the final achievement test for second – year non – major students at Electronic – Electrical Engineering Department, Nam Dinh University of Technology Education” is chosen with the hope that the study will be helpful with the author, the teachers, the test-takers and everyone who is concerned with language testing in general and validity of an achievement test in particular Due to limit time in collecting students’ scores, this study is different from the previous study The author only focuses on the face validity of this test The author hopes that the result of the study can then be applied to improve the current test and to create a new really reliable item bank It is also intended to encourage both teachers and learners in their teaching and learning 1.2 Scope of the study The scope of this thesis is limited to a research on teachers’ and test-takers’ evaluation of the existing achievement test in terms of its face validity for the second-year non-English major students at Electronic – Electrical Engineering Department, NUTE due to the limitations in time, ability and availability of data Moreover, it is impossible for the author to cover all used final achievement tests as well as design a sample achievement test for second-year students Instead, only a test specification for test 12 in semester is presented 1.3 Aims of the study Following the scope of the research above, the aims of this research are: To indentify the English teachers and students’ evaluation of the final existing achievement test (test 12) at NUTE in terms of face validity To provide suggestions for test designers 1.4 Methods of the study In order to achieve the above aims, the study has been carried out as follows: First, the author goes to library to read theory about assessment and testing, achievement test with characteristics of a good achievement test and test validity with a special focus on face validity and some measures to increase it From her critical reading, many reference materials have been gathered, analyzed, and synthesized to draw out a z theoretical basis to evaluate the current test being used for the 3rd semester students in terms of its face validity Then, qualitative methodologies involving data collected through survey questionnaires and interviews were employed from both teachers and students at NUTE 1.5 Research questions This study is implemented to find answers to the following research questions: What are the teachers’ and test takers’ (students’) perceptions of the final 3rd semester English achievement test at NUTE in terms of its face validity? What are suggestions to improve face validity of the final 3rd semester English achievement test at NUTE? 1.6 Design of the study The thesis is divided into four major chapters: Chapter 1: Introduction presents basic information such as: the rationale, the scope, the aims, the method, the research questions and the design of the study Chapter 2: Literature review reviews theoretical backgrounds on evaluating a test, which includes relationship between teaching, learning and assessment, purposes of formative and summative assessments, achievement tests, characteristics of good EGP and ESP tests, face validity and some measures to increase face validity Chapter 3: The study is the main part of the thesis showing the context of the study and the detailed result obtained from collected tests and findings in response to the research questions Then, the author gives some solutions to improve the final achievement test Chapter 4: Conclusion offers conclusions and proposes some suggestions for further research on the topic z VI A Adequate B Not enough C Abundant Do you have measures to prevent cheating in the exam?

for an electric current All metals are conductors However, some metals not conduct well Maganin, for example, is a poor conductor Copper is a good conductor, therefore it is widely used for cables A non-metal which conducts well is carbon Salt water is an example of a liquid conductor A material which does not easily release electrons is called an insulator Rubber, nylon, porcelain and air are all insulators There are no perfect insulators All insulators will allow some flow of electrons However, this can usually be ignored because the flow they permit is so small Semiconductors are midway between conductors and insulators Under certain conditions, they allow a current to flow easily but under others, they behave as insulators Germanium and silicon are semiconductors Mixtures of certain metallic oxides also act as semiconductors These are known as thermistors The resistance of thermistors falls rapidly as their temperature rises They are therefore used in temperature-sensing devices …… All good conductors are non – metals …… Copper does not allow an electric current to flow easily …… Rubber provides an uneasy path for an electric current …… Porcelain is not a perfect insulator …… The resistance of a thermistor is higher at low temperature than at high temperature z X II Give the correct passive forms of the verbs in brackets (2.5 pts) A pn junction is formed if two crystals of a semiconductor material, one of p-type and one of n-type (join) together Radio frequency waves (use) to carry audio frequency waves over long distances through the air For a long time, hi-fi

another conductor, an electromotive force (will enduce) in that conductor III Translate into Vietnamese (3.0 pts) A typical radio tuner circuit consists of an inductor and capacitor connected in parallel The side of the aerial inductance coil can be kept small by winding it on a ferrite rod core The RF waves fed to the tuner cause the circuit to oscillate The impedance of the circuit is smaller and the oscillator is greatest at a particular frequency known as the resonant frequency This frequency is determined by the values of the inductance and the capacitance By using a variable capacitor, the circuit can be tuned to the required radio frequency and the selected RF wave passed on to the RF amplifier IV Translate into English (2.0 pts) Động điện máy biến đổi điện sang thành
