The purposes of this study investigated the effects of placement of analogy on the conceptual changes of air of elementary students, while learning the air conceptions.
The subjects consisted of 108 students who are in the sixth grade classes in an elementary school in Busan city. For this study, comparative group(37 members), experimental groupⅠ(37 members), and experimental groupⅡ(34 memgers) were selected.
A pre-test and a post-test on the air conception were done both for the comparative group and the experimental groups.
The results are as follows.
First, the averages of experiment group I and II are statistically higher than comparative group's. By the way, it just has a small gap between the comparative group and the experimental Ⅱ. In other words, activity of analogy does not keep always constant to change of air conceptions of elementary students. Therefore, it has a different reason that only before or after during the analogy.
Second, it shows that experimental group Ｉ has effected on a more change of air conceptions as compared with experimental group Ⅱ. Then, the first group’s result shows better than the other group’s result.
From this result, six grade students showed a change of air conceptions very well by analogy. It means if the analogy is given to students at the beginning state of chapter, they can understand scientific concepts easily.
