Abstract

The goal of this study is to assess the effects of Scratch programming classes on preservice teachers by using computational thinking and cognitive evaluations based on Bloom's taxonomy. To pursue this research goal we measured preservice teachers' programming skills using cognitive evaluation items based on Bloom's taxonomy after preservice teachers took one-semester Scratch programming course. In addition, a survey focused on computational thinking (CT) concepts, CT practices, and CT perspectives was conducted. We also conducted artifact-based interviews to unpack preservice teachers' experiences of working on team projects and analyzed their experiences qualitatively. The results of this study are meaningful because we assessed preservice teachers' experiences comprehensively with both quantitative and qualitative methods. In addition, this study provides us with implications for evaluation perspectives in designing programming courses for preservice teachers by adopting Bloom's taxonomy scheme.

본 연구에서는 스크래치 프로그래밍 수업이 초등예비교사에게 미치는 영향을 컴퓨팅 사고력과 블룸의 텍사노미를 활용한 인지적 평가를 통해 확인하고자 하였다. 이를 위해 한 학기 동안 스크래치 프로그래밍 수업을 진행하고 예비교사의 객관적인 프로그래밍 능력을 평가하기 위해 인지적 평가 문항을 블룸의 텍사노미를 기반하여 측정하였다. 또한 초등예비교사들의 컴퓨팅 사고(Computational Thinking) 개념, 수행, 관점에 초점을 둔 설문을 실시하는 한편 팀프로젝트를 가지고 산출물 기반 인터뷰(Artifact-based Interview)를 실시하고 팀프로그래밍 경험을 정성적으로 분석하였다. 본 연구는 프로그래밍 수업을 통한 예비교사의 컴퓨팅 사고를 양적 및 질적으로 보다 포괄적으로 평가하였다는 점에서 의미가 있다. 또한 프로그래밍 능력을 블룸의 텍사노미 체계에 의해 객관적으로 평가해 봄으로써 향후 예비교사 프로그래밍 수업 설계에 대한 평가 측면의 시사점을 제시하고 있다.
