Cluster Analysis of Students’ Understandings of Enzyme-Substrate Interactions

Previously in the Bretz Chemistry Research Group, misconceptions were found concerning enzyme substrate interactions by interviewing students to identify their understanding of representations. An Enzyme Substrate Interactions Concept Inventory (ESICI) was developed from the collected data. The inventory was a 15 multiple choice assessment that used multiple representations to identify students’ understandings of enzyme substrate interactions. The ESICI was distributed to 16 institutions across the United States, and a total of 707 biochemistry students completed the inventory. The ESICI data collected was subjected to cluster analysis in order to identify and distinguish predominant groups of students who share the same patterns in regards to their same misconceptions or correct thinking. MIkayla’s research was honored as Runner-Up for the best chemistry education research poster by an undergraduate at the American Chemical Society national meeting in New Orleans!
