Abstract

In this case study, we analyzed the processes of STEAM lessons conducted by preservice secondary science teachers. Three preservice science teachers at a college of education in Seoul participated in this study. After the workshop for STEAM education, they planned and practiced STEAM lessons. All of the teaching-learning materials were collected before lessons, and their lessons were observed and videotaped. Semi-structured interviews were also conducted before and after their lessons. The processes of STEAM lessons were analyzed while focusing on PCK and PDC. Their difficulties, needs, and views on STEAM education were also studied. It was found that they have taken much efforts to reflect the objectives and characteristics of STEAM education, and prepared teaching-learning materials by searching on the internet and arranging creative contents. Their great difficulty was to determine topics for STEAM lessons. While one preservice teacher satisfied with her lesson perceived STEAM education positively, the others perceived that it would be very difficult to practice STEAM lessons in school. For their STEAM lessons to be successful, the workshop needs to include some specific information on grades, proper topics for each grade, ways of making materials, and tips for effective STEAM lessons. In addition, it will be effective if the workshop is carried out after their study on constructivist learning theory and if they experience successful STEAM lessons.

이 연구에서는 중등 예비과학교사의 STEAM 수업 시연 과정에서 나타나는 특징을 사례 연구를 통해 분석하였다. 서울 소재 사범대학의 예비과학교사 3명이 연구에 참여하였고, 이들은 STEAM 교육에 대한 워크숍을 받은 후 STEAM 수업을 계획하고 실행하였다. 수업 실행전에 예비교사들이 제작한 모든 교수-학습 자료를 수집하였고, 수업을 관찰하면서 모든 수업 장면을 녹화하였으며, 수업 전후에 반구조화된 면담을 실시하고 녹음하였다. 예비교사의 STEAM 수업 시연 과정에서 나타나는 특징은 PCK와 PDC의 측면에서 중점적으로 분석하였고, 어려움과 교육요구, STEAM 교육에 대한 견해도 조사하였다. 연구결과, 예비교사들은 STEAM 교육의 목표와 특징을 수업에 충분히 반영하려고 노력하였고, 인터넷으로 검색되는 교수-학습 자료나 창의적인 내용을 배치하여 수업 자료를 구성하는 것으로 나타났다. 예비교사들이 가장 어렵다고 느낀 것은 STEAM 수업의 주제를 선정하는 것이었다. 또한 자신의 수업에 만족한 1명의 예비교사는 STEAM 교육에 대해 긍정적 생각을 갖고 있는 반면, 나머지 2명의 예비교사는 학교현장에서 STEAM 수업이 적용되기 어려울 것이라는 생각을 갖고 있는 것으로 나타났다. 학교 현장에서 STEAM 수업이 성공적으로 실행되기 위해서는, 예비교사를 위한 워크숍에서 수업을 효과적으로 진행할 수 있는 대상 학년과 그에 맞는 주제, 수업 자료 제작 방법, 수업 실행 시 주의할 점 등에 대한 구체적 정보를 안내할 필요가 있다. 또한 워크숍은 예비교사가 구성주의 학습 이론을 접한 후에 진행하고, 워크숍에서 예비교사가 성공적인 STEAM 수업을 경험하도록 하는 것이 효과적일 것이다.
