EVALUATION OF TEST QUESTIONS USING THE ITEM ANALYSIS FOR THE CREDIT TEST OF THE SUBJECT OF MATHEMATICAL METHODS IN ECONOMICS IN THE MOODLE LMS

The Moodle system has been used within the CULS in teaching for almost two years. This paper deals with its utilization in the subject of Mathematical Methods in Economics II. The Moodle course of this subject provides students with basic and organization information, figures and tasks for exercises, software for solving them if necessary, video-records of methods and, of course, tests. The aim of this contribution is to analyze one of these tests and to summarize recommendations for improving it. The item analysis is used for this purpose. First the definitions of the item analysis indicators are given. Then they are computing using the Moodle system. All of them were very different at particular questions and it means that single questions had a different quality. The quality even depended neither on the topic nor on the form of the question (it often happened that two similar questions were evaluated very differently). The proper analysis is shown on several particular examples of questions. The item analysis has shown to be a very efficient tool for evaluation of test questions and there is no other way how to get some of the information obtainable by this analysis.
