Development of a Similar-question Generator to Support Peer Teaching

Abstract

We developed a similar-question generator that can produce a set of similar questions based on the content of an extensible markup language description file, including definitions of variables and a calculation formula for correct or incorrect answers and choices. For the evaluation of the generator, we installed it in our learning management system (LMS) and used the LMS in three general chemistry classes. The results of the recorded data compared with data from the control group showed that the exercise using similar questions among students activated more peer teaching than the exercise that offered identical questions for all students. With regard to term examinations, the scores for the questions in exercises that posed similar questions significantly increased compared with the scores for the questions in exercises that posed identical questions. Finally, according to the results of a questionnaire survey, the exercise offering similar questions was viewed favorably by 82% of respondents, especially those in the middle and low achieving students.
