ON OPEN-ENDED AND CLOSED-ENDED QUESTIONS IN DIDACTIC TESTS OF MATHEMATICS

Since educational assessment of pupils is one of the most important activities in educational process the topic of didactic tests is currently very discussed by teachers and pedagogical experts. There exist a lot of factors that have effect on quality of the didactic test. One of them is a kind of test questions (open-ended or closed-ended). In the case of closed-ended questions a pupil has to choose an answer from given variants. These questions are the most frequented form in the world and they are also quite commonly used at Czech schools. There are described the methods as well as process and results of research connected with this problem in mathematical education at elementary school there. The aim of the research was to answer the question: Are pupils more successful solving the test with open-ended or closed-ended questions? Using statistic test of significance there was validated hypothesis that the kind of questions does not play any significant role in the fruitfulness of solving the tests.
