传统的物理化学实验的修订版已经开发,以加强学生在实验室中的讨论,并提高学生的物理化学概念和真实的分子系统之间的联系。在这个实验中,学生探索2,4-戊二酮的酮-烯醇互变异构。然而,与以前的实验不同,学生们遵循一条关于数据收集和解释的调查路线。学生提供了许多结构化的机会,讨论和合作的数据分析。提供了一个实验的一般大纲,突出了学生的决策和基于探究的学习这个平衡系统的热力学领域。学生活动和成果的描述表明,学生有机会建立自己的理解,并对实验设计作出决定。
A revised version of a traditional physical chemistry laboratory experiment has been developed to enhance student discussion in the laboratory and to improve students’ connections between physical chemistry concepts and real molecular systems. In this experiment, students explore the keto–enol tautomerization of 2,4-pentanedione. However, unlike in prior versions of this experiment, students follow a line of inquiry about data collection and interpretation. Students are provided many structured opportunities to discuss and collaborate on the analysis of data. A general outline of the experiment is provided that highlights areas of student decision-making and inquiry-based learning about the thermodynamics of this equilibrium system. A description of student activities and outcomes shows that students are afforded a number of opportunities to build their own understanding and make decisions about experimental design.
