Abstract

The purpose of this study are to develop the TEP activity for learning experimental apparatus at elementary school and to test the effects of the TEP activity. This study consists of two steps. First through literature research on the difficulties and needs of experimental apparatus education developed the form that how to educate the experimental apparatus at elementary school. Second, applied the TEP activity and figured out the effects as two aspect(knowledge about experimental apparatus and actual using skill during lesson). This worksheet was applied to 3rd grade students in elementary school about 4 experimental apparatuses(Beaker, Electronic scale, Glass rod, Spatula). The results of this study are as follows: There is no specific time to teach what is and how to use experimental apparatus by regular curriculum. So many students and teachers need method and time to learn them. Also they want to lots of opportunities to use them. With that needs given previously, TEP activity developed by 3 steps. 1. Trigger interest 2. Explore experimental apparatus: learned knowledges about experimental apparatus focused on appearance(name, purpose, directions for use, precautions) 3. Practice experimental apparatus: actual using time to acquire skills. After that did the survey of knowledge and observation of students' behavior during usual class to confirm the effects. According to the results, TEP activity helped the students to improve there awareness of the experimental apparatus and actual using skills.

본 연구에서는 초등학생의 실험기구 교육을 위한 TEP 활동(Trigger interest; 흥미 유발-Explore experimental apparatus; 실험기구 탐색-Practice experimental apparatus; 실천적 사용)을 개발하고 이를 적용하여 그 효과를 알아보았다. 과학을 처음 접하는 초등학교 3학년을 대상으로 교과서에 제시되어있는 실험기구 중 4가지(비커, 전자저울, 유리막대, 약숟가락)를 선별하여 연구를 진행하였다. 그 결과 TEP 활동을 통해 단편적인 사용법이나 주의사항만을 알고 있던 학생들이 실험기구의 생김새에 따른 특징과 연관 지어 실험기구에 대한 설명을 할 수 있게 되었다. 또한 실제로 사용해보는 활동을 통해 실험기구 사용 능력이 향상되었다. 평소 과학 수업에서의 모습을 관찰한 결과 실험기구에 대해 학습한 내용을 떠올리며 적절하게 사용하려는 학생들이 많아졌으며 반복적인 활동을 통해 그 수가 증가함을 알 수 있었다. 초등학교에서 처음 배우게 되는 실험기구에 대한 지식적 이해와 사용 능력은 초, 중, 고등학교를 지나 실험이 주로 이루어지게 되는 대학교까지 영향을 미친다. 잘못된 용도와 사용법으로 실험을 하게 된다면 실험 결과의 신뢰도가 떨어질 뿐만 아니라 안전사고의 확률 또한 높아진다. 이러한 관점에서 본 연구를 통해 실험기구에 대한 교육을 초등 과학 교육과정에서 더욱 중요하게 다루어져야 하며 실제 교육을 해야 하는 교사들을 위해 다양한 교육 자료나 교수법이 개발되어야 함을 확인할 수 있었다.
