Experiment And Case Study Of The Effect Of Repetitive Exercises

Repetitive drill is a common educational means in Chinese schools. Students doing repetitive exercise for a long period of time without feedbacks or guidance. In this article, we compare the effect of repetitive drill on two different kinds of mathematic problems, which are named calculation question and ratiocination question. The current is consist with three parts:Experiment1, Experiment2, and the Case study. Experiment1compares the training effect of calculation question and ratiocination question. Experiment2compares the training effect of two kinds of problems under two conditions:with or without feedback. The case study is a follow-up study of a special student, in order to analysis the bad effect of long-term repetitive drill.The results shows that (1)The effect of repetitive drill is specific. In general, the training is effective for the maths problems of information extraction like calculation questions in this study, but not effective, even harmful for those problems needs students master well the relevant mathematical theorems underlying the problems, like the ratiocination questions in this study.(2) The current study also indicates that various types of students show a specific effect of the repetitive drill.(3) Feedbacks is necessary for ratiocination question. The accuracy increases under feedback condition, but decrease without feedback.(4) The Case study find that long-term repetitive drill will cause negative self-regulation and utilitarian view of study.
