Abstract

In order to find out Elementary pre-service teachers' reflective thinking and experiment performance ability related with Photosynthesis Experiment in the Korea Elementary School Science Textbook, the research is conducted targeting Elementary pre-service teachers. They are asked to carry out the experiment and write their own report about the difficulties and solutions of exploration process. This study aims to analyze Elementary pre-service teachers' reflection and experiment performance ability on Photosynthesis experiment based on 10 groups' reports and presentation materials. Reflective thinking extracts 108 statements which is associated with the four types of the sentence 'Knowledge, Procedure, Orientation, Attitude' in 10 reports. There are many sentences about reflective thinking acquired through analysis of the photosynthesis experiment. reflective thinking about the newly discovered type or changed concepts through experimentation in Knowledge is at the highest frequency. 56 sentences in relation to the ability to perform experiments are extracted by adding 4 different types of reflective thinking in 10 groups shown the highest frequency group and the lowest frequency group's report through analyzing 4 steps 'Experimental preparation and safety accident prevention', 'Experiments performance', 'Experimental results and generalization', and 'Experimental results and feedback.' Results of the analysis showed that there are the biggest difference between the two groups in 'experiment results supplement and feedback step.' In the lowest group's report, there's no contents related with 'Computer-assisted information processing' in the 'Experimental results summary and generalization stage', 'Alternative reagents and materials research', and 'Devising alternative experiment methods'.

본 연구는 초등학교 과학교과서에 수록된 광합성 실험을 초등 예비교사들이 직접 수행하고 그 실험결과와 자신의 반성을 담은 탐구과정상의 어려움과 해결책을 탐구보고서에 작성하도록 하였다. 10개조의 탐구보고서와 발표자료를 바탕으로 초등 예비교사들의 반성적 사고와 실험 수행 능력을 분석하였다. 반성적 사고에 대해서는 10편의 탐구보고서에서 '지식', '과정', '지향', '태도' 4가지 유형과 관련된 총 108개의 진술 문장을 추출하였다. 분석 결과 광합성 실험을 통해 획득한 '지식'에 대한 반성적인 사고에 대한 내용이 가장 많았다. 지식유형에서도 실험을 통해 새롭게 알게 된 것이나 기존의 개념이해가 변화한 내용에 대한 반성이 가장 높은 빈도를 보였다. 실험 수행 능력은 10개조 중 반성적 사고 4가지 유형을 합산하여 가장 높은 빈도를 보인 한 개 조와 가장 낮은 빈도를 보인 한 개 조의 탐구보고서를 '실험준비 및 안전사고 예방', '실험 수행', '실험결과 정리 및 일반화', '실험결과 보완 및 피드백' 4단계에 따라 분석하여 56개의 문장을 추출하였다. 분석 결과 '실험결과 보완 및 피드백' 단계에서 두 조 간에 가장 큰 차이를 보였다. 최하위 조의 경우 '실험결과 정리 및 일반화' 단계의 '컴퓨터를 이용한 정보 처리', '대체 시약 및 재료 탐색', '대체 실험법 고안' 능력과 관련된 내용은 탐구보고서에서 찾을 수가 없었다.
