Abstract

This study explores the application of constructionist learning principles through drawing to enhance undergraduate biology students' understanding of DNA replication. Using a pre-post design, 108 students in an introductory biology course engaged in instructor-led drawing sessions to illustrate concepts of DNA replication. Pre- and post-surveys assessed students' confidence in understanding various aspects of the process. Drawings were evaluated for accuracy and clarity using a standardized rubric. Results indicate significant improvements in student confidence across all surveyed topics. However, accuracy and clarity of drawings decreased for more complex concepts. The study demonstrates the potential of constructionist approaches like drawing to enhance comprehension of abstract biological concepts, while also revealing areas where additional instructional support may be needed for more challenging topics.
