摘要

在指导性探究学习中,将动态和静态建模相结合,可以帮助学生从宏观、象征和微观层面理解化学概念。本研究旨在检验和解释在氧化还原反应概念的动态和静态建模指导下进行探究所教授的学生多重表征能力的差异。本研究采用描述性和准实验性设计。使用描述性和manova统计分析对数据进行分析。结果表明,采用动态建模与静态建模相结合的引导探究教学,学生的宏观水平能力是一致的。而采用动态建模指导探究教学的学生符号和微观层面的能力高于采用静态建模指导探究的学生能力。本研究的意义在于,动态建模的化学学习可以帮助学生更容易地构建化学概念,并获得完整的理解。

Dynamic and Static Modeling Embedded in Inquiry Learning to Improve Student’s Multiple Representation Ability
Integration of dynamic and static modeling on guided inquiry learning can help students to understand chemical concepts at macroscopic, symbolic and microscopic levels. This research aimed to examine and to explain the differences of students’ multiple representation ability that was taught by guided inquiry with dynamic and static modeling in redox reaction concept. This research used descriptive and quasi-experimental design. Data were analyzed using descriptive and manova statistics analysis. The results showed that the ability of students’ macroscopic level that was taught by guided inquiry with dynamic and static modeling is the same. While the student’s symbolic and microscopic level ability that was taught by guided inquiry with dynamic modeling higher than student’s ability that was taught by guided inquiry with static modeling. The implication of this research is chemistry learning with dynamic modeling can help students to construct chemical concept more easily and gain the complete understanding.
