Abstract

The purpose of this study is to analyze the questions generated by elementary school pre-service teachers when reading the teacher's guide for the refraction of light, and to analyze the difficulties in understanding the concept and in making instructional plans. A total of 592 meaningful questions were generated by 283 elementary school pre-service teachers after reading the teacher's guide of 'light and lens' unit in the 6th grade of the 2015 revised curriculum. Of these, 306 questions are for understanding the concept of physics and 286 are pedagogical questions. As a result of the analysis, in terms of understanding the concept of physics, the elementary school pre-service teachers encounter difficulties in understanding the concept of the 'cause' of the phenomenon suggested in the textbook, such as the cause of refraction, the reason for scattering light, and the cause of the image change depending on the focal length of the convex lens. In terms of instructional planning, it was followed by questions about how to explain concepts, questions about not being able to explain concepts to elementary school students and having to teach only phenomena, specific explanation methods for specific concepts, and experimental methods. Although the teacher's guide contains various explanations and supplementary materials to help teachers understand the concept, it can be seen that there are many elementary pre-service teachers who cannot answer questions about some concepts even after reading the guide. For concepts with a high frequency of questions, it is necessary to prepare a tutorial that is more understandable. In the instructional plan, there were many questions about teaching methods and experimental methods, so it is necessary to provide more examples and specific experimental methods for explaining concepts in the teacher's guide.

이 연구는 초등예비교사가 빛의 굴절 단원의 교사용 지도서를 읽을 때 생성한 질문을 분석함으로써 개념이해에 있어서의 어려움과 지도계획을 세울 때의 어려움에 어떤 것이 있는지를 분석하는 것을 목적으로 한다. 2015 개정 교육과정 6학년 1학기 '빛과 렌즈' 단원의 지도서를 읽고 초등예비교사 283명이 생성한 의미있는 질문은 총 592개였고 이 중 물리 개념이해를 위한 질문은 총 306개, 교육학적 질문은 총 286개였다. 분석 결과, 초등예비교사는 물리 개념이해 측면에서 굴절이 일어나는 원인, 빛을 산란시켜야 하는 이유, 볼록렌즈의 초점거리에 따른 상의 변화 원인 등 교과서에 제시된 현상이 일어난 '원인'의 개념 이해에 어려움을 가지고 있었다. 지도계획 측면에서는 개념의 설명방법에 대한 질문, 즉 초등학생에게 개념에 대한 설명을 하지 못하고 현상만을 지도하여야 하는 것에 대한 질문, 특정 개념에 대한 구체적인 설명방법, 실험 방법 등에 대한 질문 그 뒤를 이었다. 교사용 지도서에는 교사들의 개념이해를 돕기 위한 여러 가지 설명들과 보충자료가 포함되어 있음에도 불구하고 일부 개념에 대해서는 지도서를 읽고서도 의문이 해결되지 않는 초등예비교사가 많이 있다는 것을 알 수 있다. 질문의 빈도가 높은 개념에 대해서는 좀 더 알기 쉽게 지도서를 작성할 필요가 있다. 지도계획에 있어서는 교수법과 실험방법에 대한 질문이 많았기 때문에 교사용 지도서에서 개념의 설명방법에 대한 예시와 구체적 실험방법을 좀 더 제공할 필요가 있다.
