Elementary School Students' Conceptual Change on Electric Current by Drill and Practice Type CAI Program.

The purposes of this study were to investigate what kinds of idea the children have after formal instruction in school, and to investigate what is the children's conceptual change on electric current after implementation of drill and practice type CAI program about electric circuit. The CAI program was developed by KEDI research project team the author of this article was joined. The subjects were 20 eleven yaers old(elementary fifth year) children sampled from a elementary school in Seoul, Korea. They had already learnt about electric circuits for two years before implementing this CAI program according to the formal science curriculum. The pretest were accomplished before implementing the CAI program, and posttest were accomplished a week after implementation of the CAI program. The results of this study are as follows: Even though they had studied electric circuits, only 5% of the students had scientific ideas before pretest, and even after drill and practice type CAI program only 30% of the students have changed their misconceptions into scientific conceptions.
