The Design And Development Of Test System Of The Students' Knowledge Structure

As is known that, it is very important to know the knowledge structure in both study and teaching. According to the feedback information in test, students can promptly acknowledge their own cognition flaw to help them study initiatively.At the same time, the teacher can promptly know about students' study condition and the cognition flaw, and keep abreast of student's study situation and carry on pointed teaching which suits students' particular case, thus, it can achieve truely"teaches students in accordance with their aptitude".In 1985, Doignon and Falmagne proposed the knowledge space theory, it is a kind of the psychology theory to describe the students'state-of-the-art and the knowledge structure.The design and development of the study test system is an attempt based on the demonstration of the knowledge in the fourth chapter of logic operation and judgment selection control in the book"C Language Programming"by Tan Haoqiang, taking the knowledge space theory as the instruction.This process carries on the deletion or the retention to the current knowledge condition according to the students'current answer situation, and then in terms of the rest knowledge condition and the question rule, the system can choose students' suitable topic, Finally, when the only knowledge condition is left, setting question stops. At last the only knowledge condition is namely the possible knowledge structure of the students, the system gives studying advice with which students can improve knowledge structure.After system design and initiative development, the black box test method is used to test all the function surfaces of system, and the test result proved that the system function is consistent with the expectation result.
