Abstract
The main purpose of this study is to propose a new educational method for constructivistic understanding of science and to test the validity of the method proposed. For this purpose, the author let students try the KJ method before and after the lecture on nature of science and its related issues. The task for students on applying the KJ method is "to choose and categorize the words necessary for describing and explaining science". There are two aims at applying the KJ method to this study. One is to investigate the change of students' view of science caused by lectures, the other is to let students understand science in constructivistic way by writing a composition compared science with the KJ method. From analizing the change of the words for sciece which students wrote down before and after the lecuture and the compositions, we can estimate to what extent students understand science in constructivistic way.
