Beyond textbook illustrations: Hand-held models of ordered DNA and protein structures as 3D supplements to enhance student learning of helical biopolymers

| Summary: | Textbook illustrations of 3D biopolymers on printed paper, regardless of how detailed and colorful, suffer
from its two-dimensionality. For beginners, computer screen display of skeletal models of biopolymers
and their animation usually does not provide the at-a-glance 3D perception and details, which can be
done by good hand-held models. Here, we report a study on how our students learned more from using
our ordered DNA and protein models assembled from colored computer-printouts on transparency film
sheets that have useful structural details. Our models (reported in BAMBED 2009), having certain distinguished features, helped our students to grasp various aspects of these biopolymers that they usually
find difficult. Quantitative and qualitative learning data from this study are reported. |
