기원론적 접근법에 따라 개발한 과학사 프로그램이 학생들의 입자론적 물질관 및 과학의 본성에 대한 이해에 미치는 영향

Abstract

this study, science history program was developed to enhance student’s concepts toward the particulate nature of matter and the understanding about the nature of science. And the effects of its application was investigated in the lesson of Composition of Matter in middle school science class. This science history program was based on genetic approach and included the contents from the old Greek natural philosophers to Avogadro. Before instruction, the test of understanding about nature of science was administered, and the science scores of the previous course were obtained, which were used as covariates. During 24 class hours, this study was conducted with two classes(experimental and comparison group) in a middle school in Seoul. The experimental group was received lessons by science history programs and the comparison group was received traditional lessons. After instruction, the scientific concept test, the test of understanding about nature of science were administered. The result of this study indicates that the scientific concept scores of experimental group were significantly higher than comparison group at p<.01 level of significance. It means that the students in experimental group has more sound conceptions about the particulate nature of matter and less misconceptions about matter than the students in comparison group. However, there was no significant difference between two groups in the score of understanding about the nature of science.
