In order to achieve this aim, a combination of both qualitative and quantitative research methods were adopted. The findings indicate that there is a certain degree of unreliability in the final achievement computer-based MCQs test1 and there are two main factors that cause the unreliability including test item quality and test- takers performance. ’ Having carefully considered a thorough analysis of the collected data, the author made some suggestions in order to improve the quality of the final achievement test and the MCQs test 1 for the non-majors of English in the 4 th semester in Hanoi University of Business and Technology. Firstly, the test objectives, sections and skill weight should be adjusted to be more compatible with the course objectives and the syllabus. Secondly, a testing committee should be set up for the construction and development of a multi choice item bank including test items which are of good p-value and discrimination value. iii LIST OF ABBRIVIATIONS 1.

Rationale of the study Testing plays a very important role in teaching and learning process. Testing is one form of measurement which is used to point out strengths and weaknesses in the learned abilities of the students. Through testing, especially tests scores we may discover the performance of given students and of teachers. As far as students are concerned, test scores reveal what they have achieved after a learning period. As for teachers, test scores indicate what they have taught to their students. Based on test results, we may make improvement in teaching, learning and testing for better instructional effectiveness. Another reason for the selection of testing a matter of study lies in the fact that the current language testing at Hanoi University of Business and Technology (HUBT) has been under a lot of controversy among students and teachers. Testing is mainly carried out in the form of two objective tests on computers (named test 1 and test 2) which are administered at the end of each semester. The scores that a student gets on these tests are the main indicators of his or her performance during the whole semester. There are different comments on the results of these tests, especially the test 1 for the second-year non-English majors. Some subject teachers claim that these tests do not truly reflect the students’ language competence. Others say that these tests are appropriate to what students have learnt in class and compatible with the course objectives and therefore reliable. Also, among the students, do opposite ideas exist. Many think that these tests are more difficult than what they have learnt and studied for the exam, others say that these test items are easy and relevant to what they have been taught. Therefore finding out whether the tests are closely related with what the students have been learnt and what the teachers have taught, also, whether these tests are of reliability is indispensable. For the two reasons mentioned above, the author would like to undertake this study entitled A study on the reliability of the final achievement Computer-based MCQs Test“ 1 for the 4th semester non-English majors at Hanoi University of Business and Technology” with the intention to examine rumors about this test. In addition, the author hopes that the study results help to raise awareness among teachers as well as those who are interested in this field. At the same time, study results, in some extent, can be applied to improve the current testing situation in HUBT. 1.2.

The main different is that the test is delivered on computers and students simply click mouse for their chosen response among A, B, C, D This kind of test is different from computer adaptive tests which are tailored to the particular abilities of the candidate In 16 other words, a Computer- based MCQs test at HUBT is in fact an MCQs test delivered on computers The following chart illustrates testing guideline... different students and to reflect individuals’ performance of the same group 2.2 Achievement test 2.2.1 Definition Achievement tests are of extensive use at different levels of education due to their distinguished characteristics Researchers define the notion of achievement tests in various ways Henning (1987, p.6) held that: Achievement tests are used to measure the extent of learning in a prescribed... period of learning and it should attempt to cover as much of syllabus as possible 2.2.3 Considerations in final achievement test construction On the basis of its characteristics, Heaton (1990) put that covering much the contents of a syllabus or a course book is a requirement for designing a final achievement test Testers should avoid basing the test on their own teaching rather than on the syllabus... language tests and criteria of a good test are also discussed Section 2.2 classifies achievement tests into two types and mentions consideration in designing final achievement tests The definition, benefits and limitations of MCQs tests and principles of this type of test construction are dealt with in section 2.3 The final Section - 2.4 is concerned with test reliability, methods for estimating test... noted that the proponents of computer- based testing can point to a number of advantages First, just as paper-done MCQs tests, scoring of fixed response items can be done automatically and the candidate can be given a score immediately Second, the computer can deliver tests that are tailored to the particular abilities of the candidate This type of test, as also called computer- adaptive test, can provide . analysis of the final achievement computer- based MCQs test 1- 150 items, 349 examinees XII APPENDIX 5 Item indices of the final achievement computer- based. student’s attitude towards the final achievement Computer- based MCQs test 1? 1.3.
