Abstract

This study investigated the effects of varying visuals in drawing and writing as methods to assist students in connecting and integrating multiple external representations provided in learning the particulate nature of matter. Seventh graders (N=233) at a coed middle school were assigned to control, static drawing (SO), dynamic drawing (DD), static writing (SW), and dynamic writing (DW) groups. The students were taught about "Boyle's Law" and "Charles's Law" for two class periods. Two-way ANCOVA results revealed that the scores of a conception test for the two drawing (SD, DD) groups and the two writing (SW, DW) groups were significantly higher than those for the control group. Within the writing groups, students of lower spatial visualization ability in the DW group scored significantly higher than those in the SW group. However, no significant differences were found in the scores of the conception test for the two drawing (SD, DD) groups regardless of students' visualization ability. Researchers also found that most students in both DD and DW groups had respectively positive perceptions of dynamic visuals in drawing or writing.

이 연구에서는 물질의 입자성에 대한 개념 학습에 제공되는 다양한 외적 표상들 간의 연계와 통합을 촉진시키는 방안으로 고안된 그리기와 쓰기에서, 학생들에게 제공되는 시각적 정보의 형태(정화상/동화상)에 따른 교수 효과를 조사하였다. 남녀공학 중학교 1학년 233명을 통제 집단, 정적 그리기(SD) 집단, 동적 그리기 (DD) 집단, 정적 쓰기(SW) 집단, 동적 쓰기(DW) 집단으로 배치한 후, '보일의 법칙'과 '샤를의 법칙'에 대하여 2차시 동안 수업을 실시하였다. 개념이해도 검사 점수에 대한 이원 공변량 분석 결과, 그리기(SD, DO) 집단과 쓰기(SW,DW) 집단의 점수가 통제 집단의 점수보다 통계적으로 유의미한 차이로 높았다. 사각적 정보의 형태(정화상/동화상)에 따른 교수 효과를 비교한 결과, 쓰기에서는 정화상보다 동화상을 제공하였을 때 공간 시각화 능력이 낮은 학생들의 개념 이해도 검사 점수가 더 높았으며, 그 차이가 통계적으로 유의미하였다. 반면, 그리기에서는 공간시각화 능력에 관계없이 시각적 정보의 형태에 따른 개념 이해도 검사 점수 차이가 유의미하지 않았다. 수업에 대한 인식 검사 결과에서는 동화상을 사용하는 집단(DD, DW) 학생들의 대부분이 그리기나 쓰기에서 동화상을 제공하는 것에 대해 긍정적으로 인식하는 것으로 나타났다.
