광원 모양에 따른 빛의 직진에 대한 초등학생의 학년별 이해비교

Abstract

In order to understand the optical part properly, it is necessary to have a precise understanding of the light source called “all light sources are a collection of point light sources” which is the basis of this, but it is not covered in the current 2009 revision elementary curriculum. This study compares the degree of comprehension of elementary school students according to grade level to find a grade level suitable for introducing the concept of straightness of light according to the shape of light source, which can help to understand the light source correctly. To do this, we developed the teaching and learning materials and the conceptual checklists according to the shape of the light source suitable for elementary school students, and conducted classes for each of the 3, 4, 5, and 6 grades. And we analyzed according to the response type. The results of this study show that 6th grade students have the highest level of conceptual change. In addition, in the elementary science curriculum, students are expected to form clear scientific concepts related to light concept from elementary school by introducing the straight propagation of light according to the shape of light source, and it is expected that research that determines grade level of education contents in curriculum becomes more active do.
