Description
Scale is defined as one of four benchmarks for science literacy and is also included in the NGSS framework for K-12 science curriculum. Despite these efforts, research has shown that undergraduate chemistry students have an underdeveloped understanding of scale. One effort to improve the scale literacy of undergraduate chemistry students was to implement a new sequence of laboratory experiments that highlight explicit themes of scale. Before each experiment students were given quizzes that tested specific scale concepts as they related to the experiment they were doing in laboratory that week as well as following up on the experiment done the previous week. Preliminary results for first semester general chemistry show that student quiz performance improves as a result of completing the experiment. Additionally, student responses to these quiz questions give important information to instructors as to what misconceptions students hold as they relate to understanding scale. The preliminary results of the analysis of these quizzes for second semester general chemistry will be presented.
