The Influence of Computer-Assisted Instruction Emphasizing the Particulate Nature of Matter on High School Students' Conceptual Understanding in Chemistry

Abstract

This study examined the influences of computer-assisted instruction (CAI) upon high school students' conceptual understanding about gas laws. The CAI programs were designed to supply animated molecular motions for emphasizing the particulate dynamic nature of matter. The CAI and the control groups (2 classes) were selected from a girls high school in Seoul, and taught about gas laws for four class hours. After the instructions, students' conceptions were measured by the Chemistry Conceptions Test (CCT). Data analysis indicated that the CAI group had better conceptual understanding than the control group. Several misconceptions concerning target concepts were identified.98년도 서울대학교 사범대학 발전기금 연구과
