Previous work has shown that the formation of misconceptions remains one of the most significant barriers to progress for chemistry students. Determination and visualization of the shapes of molecules using valence shell electron pair repulsion theory (VSEPR theory) is an example of an abstract concept that students often find difficult to learn. Concepts may be better understood if the learning process were supported by innovative, interactive, learning resources. In order to address the conceptual difficulties that students may encounter when using VSEPR theory, an activity has been developed that is supported by simple molecular models. Activity cards give students the opportunity to work through the steps required to predict the shape of a molecule in an engaging manner that promotes social learning. Students were tested before and after the activity. A statistically significant improvement in scores (p = 0.001) was found, which indicates that the activity cards and molecular models could help students understand the topic.

预言!VSEPR游戏:使用卡片和分子模型构建来积极增强学生对分子几何的理解

先前的工作表明,误解的形成仍然是化学专业学生进步的最重要障碍之一。使用价壳电子对排斥理论(VSEPR理论)确定和可视化分子形状是学生经常发现难以学习的抽象概念的一个示例。如果学习过程得到创新的交互式学习资源的支持,则可能会更好地理解概念。为了解决使用VSEPR理论时学生可能遇到的概念上的困难,已经开发了一项活动,该活动得到了简单的分子模型的支持。活动卡使学生有机会以引人入胜的方式促进社交学习,完成预测分子形状所需的步骤。活动前后对学生进行了测试。得分有统计显着性提高(p = 0.001),表明活动卡和分子模型可以帮助学生理解该主题。
