A Study on the Strategy of Remolding Students' Misconception and Its Mechanism

This paper deals with students' misconc eption and the process that a new concept displaces it. Many students think that plants growing from bulk (e. g. tulip) have no seed in the flowers. To correct such misconception, the control group was given reading material describing the fact that tulip has seed in the flower and could be raised. The experimental group was given reading material describing the reason why a tulip was raised from a bulk while it had seed in the flower. The main results were as follows.(1) More Ss in the experimental group abandoned their misconception and acquired new concept than Ss in the control group.(2) The experimental group was more deeply interested in the given article than the control group. The obtained results were discussed from the viewpoint of the mechanism that a new concept displaces an old one. And a general description was made concerning the teaching strategy used in this experiment.
