Cover: Student Thinking and Student Success

In Students’ Concept-Building Approaches: A Novel Predictor of Success in Chemistry Courses, Regina F. Frey, Michael J. Cahill, and Mark A. McDaniel discuss the use of an online concept-building task to differentiate students based on their concept-building approach. Recent basic cognitive science research suggests that some learners tend toward rote concept learning (exemplar learners), whereas other learners tend to use abstraction concept learning (abstraction learners). Students in general and organic chemistry completed a concept-building task, and their subsequent course performances were tracked. Abstraction learners consistently outperformed exemplar learners, with performance differences most pronounced among students taking the higher-level course, Organic Chemistry 2. Performance patterns differentiated by concept-building approach were evident even when standard ability indices (college entrance exam scores and prior chemistry performance) were factored into the analysis. One implication is that as chemistry content demands more abstraction, the way students approach learning concepts becomes more critical for success in chemistry courses.
