Chemistry courses remain a challenge for many undergraduate students. In particular, first-semester organic chemistry has been labeled as a gatekeeper with high attrition rates, especially among students of color. Our study examines a key factor related to conceptual understanding in science and predictive of course outcomes-knowledge structures.…

As faculty, our goals for students are often tacit, hidden not only from students but from ourselves as well. We present a conceptual framework for considering teaching goals--what we want our students to achieve--that encourages us to think more broadly about what we mean by achieving in our knowledge domains. This framework includes declarative…

One potential approach to the authentic assessment of what students know and can do in science is concept mapping. A concept map is a graph consisting of nodes representing concepts and labeled lines denoting the relation between a pair of nodes (concepts). The external concept map constructed by the student is interpreted as representing…
