Physical and life science disciplines emphasize how basic structural units influence function, yet it is challenging for students to understand structure-function relationships, particularly at molecular scales. Undergraduates in our biology capstone course struggled to connect mutations in a gene encoding a key protein in a cell development…

Visual demonstrations of abstract scientific concepts are effective strategies for enhancing content retention (Shmaefsky 2004). The concepts associated with gene regulation of growth and development are particularly complex and are well suited for teaching with visual models. This demonstration provides a simple and accurate model of Hox gene…

Presents a simple pedagogical model to teach the importance of antiparallel complementarity in nucleotide pairing when replication, transcription and coding are initially introduced. (HM)

During three series of molecular genetics experiments, our students engage in ungraded discussions of research articles related to their experiments. The research articles are selected less for their relevance to students' laboratory experience than for their focus on experimental design and the clarity of data presentation. By discussing these…

Discusses the use of Post-it Notes as effective teaching devices. Presents activities that use Post-it Notes including concept mapping, molecular modeling, group activities illustrating multi-step biological processes, and genetics activities. Highlights the use of the constructivist approach. (JRH)
