Abstract

This study aimed to examine the effects of argument-based chemistry laboratory investigations using the Science Writing Heuristic (SWH) approach on students' use and embedding of multimodal representations in summary writing. Participants of this study were thirty-nine freshman students majoring in science education at a National University in Korea. Argument-based chemistry laboratory investigations using the SWH approach were implemented for twenty-three students enrolled in one cohort, and the traditional chemistry laboratory teaching was implemented for 16 students enrolled in the other cohort. Summary writing samples were collected from students before and after the implementation. Summary writing samples produced by students were examined using an analysis framework for examining the use and embeddedness of multimodal representations. Summary writing was categorized into one of verbal mode, symbolic mode, and visual mode. With regard to the embedding of multi-modal representations, summary writing samples were analyzed in terms of 'constructing understanding,' 'integrating multiple modes,' 'providing valid claims and evidence,' and 'representing multiple modes.' Data analysis shows that the students of the SWH group were better at utilizing and embedding multimodal representations in summary writing as they provided evidence supporting their claims. This study provides important implications on pre-service science teacher education.

이 연구의 목적은 논의가 강조된 일반화학실험이 학생들의 글쓰기에서 나타난 다중 표상 및 다중 표상의 내재성에 미치는 영향을 알아보기 위한 것이다. 이를 위해 탐구적 과학 글쓰기 전략을 바탕으로 일반화학실험 프로그램을 개발하였고, 이 프로그램을 적용한 후, 학생들의 글쓰기에서 나타나는 다중 표상의 양식과 내재성을 비교하였다. 이 연구는 일반화학실험을 수강하는 학생들을 대상으로 화학교육과 1학년 23명을 실험집단으로, 물리교육과 1학년 16명을 비교집단으로 선정하여 총 5개의 주제를 적용하였다. 학생들이 작성한 Summary Writing에서 나타난 다중 표상의 양식과 내재성을 공변량 분석으로 비교한 결과, 양식과 내재성 모두에서 실험집단의 평균이 비교집단에 비해 통계적으로 유의미하게 높은 것으로 나타났다. 이러한 결과로부터 논의가 강조된 일반화학실험은 다중 표상 및 다중 표상의 내재성의 발달에 있어서 전통적인 실험방식에 비해 더 효과적임을 알 수 있었다. 또한 논의와 글쓰기를 지속적으로 수행하는 과정이 학생들의 과학적 개념에 대한 이해에 도움이 될 것이라 보이며, 연구 결과가 대학생을 대상으로도 효과가 있다는 것에서 프로그램의 적용 범위의 확대 측면에서 의미가 있다고 본다.
