Abstract

The purpose of this study is to identify secondary chemistry teachers' abilities to carry-out experiment lesson successfully. As far as the research method is concerned, literature reviews, analyses of abilities to carry-out experimentation from science textbooks, and a survey of science teachers' perceptions of experimental ability were employed along with the progressive discussions among the authors. In order to identify secondary chemistry teachers' abilities to carry-out experimentation, we divided the experiment lesson into three stages of preparation, conduct and arrangement, and management of lab, and added the stage of safety. Each stage is classified into sub-areas, and the sub-area consists of subordinate elements. The safety stage was included separately to emphasize the importance of the safety issue in lab and experimental activities. The secondary chemistry teachers' abilities to carry-out experimentation are the abilities to perform experiments in person, presupposing the instruction of experiment, and can be featured with the use of reagent and measuring instruments, the preparation of sample, designing experiment, correct experimental habit and skillfulness, data processing, analysis and reasoning, and management of lab and safety.

이 연구는 중등 화학 교사 전문성 및 지향점 제공을 위한 기초 조사로서, 실험 수업을 성공적으로 진행하기 위하여 필요한 화학 교사의 실험 능력에 대한 규명을 목적으로 하였다. 문헌 연구, 교과서 실험 분석, 과학 교사 설문 조사의 결과에 기초한 연구팀의 지속적인 논의를 통하여 연구를 진행하였다. 화학 교사의 실험 능력 규명을 위하여 수집된 자료들을 정리하여 크게 네 개의 단계(실험 수업 준비, 실험 수행 및 정리, 실험실 관리, 실험실 안전 관리)로 나누고, 각 단계별로 실험 능력에 관련된 소영역과 세부 내용 요소를 선별 ․ 수정하여 재배치하였다. 실험실 안전 관리는 실험실 및 실험 활동에서 ‘안전’의 중요성을 강조하기 위해 별도의 단계로 구분하였다. 화학 교사가 갖추어야 할 실험 능력은 실험 수업 지도를 전제로 하여 교사 스스로 실험 수행을 할 수 있는가에 대한 능력으로, 시약 및 측정기기 사용, 시료 준비, 실험 설계, 바른 실험 습관 및 숙련도, 자료 정리, 분석 및 추론, 그리고 실험실 관리 및 실험실 안전 관리에 관련된 능력으로 특정지어 질 수 있다.
