Disciplines such as Biochemistry and Molecular Biology, which involve concepts not included in the high-school curriculum, are very challenging for many first year university students. These subjects are particularly difficult for students accustomed to surface learning strategies involving memorization and recall of facts, as a deeper…

As online education has exploded in the past decade, the number of physics and physics-related massive open online courses (or MOOCs, to use the industry lingo) has grown substantially as well. Several such courses aim at high school students, especially those involved in the AP Physics program. One of us (BK) was involved in creating two such…

Passive, lecture-based forms of instruction are often ineffective in helping students develop deep conceptual understanding of scientific concepts. Student-centered forms of instruction based in a constructivist framework, where students are guided toward actively constructing their understanding, have been met with greater success. However,…

Adopting a new teaching approach is often a daunting task especially if one is an early adopter in a limited-resource environment. This article describes the challenges encountered and the strategies used in pilot testing a blended instructional method in a large size class within the college of education at a medium-sized university. The main…

Discussion of structural knowledge assessment for large groups focuses on the features of a "KNOT" computer program which uses a network similarity index (NETSIM) to compare novice and expert concept maps. Treatment in three high school physics classes investigated reliability as well as content, construct, concurrent, and predictive…
