In order to deepen students' understanding of natural phenomenon and how scientific knowledge is constructed, it is critical that science teachers learn how to engage students in productive scientific argumentation. Simulations for teachers are one possible solution to providing practice-based spaces where novices can approximate the work of…

The use of external representations has a potential to facilitate inquiry learning, especially in hypothesis generation and scientific reasoning, which are typical difficulties encountered by students. This study proposes and investigates the effects of a three-dimensional thinking graph (3DTG) that allows learners to combine in a single image,…

This quasi-experimental, mixed methods study examined the transfer of a well-established pedagogical strategy, Peer-Led Team Learning (PLTL), to an online workshop environment (cPLTL) in a general chemistry course at a research university in the Midwest. The null hypothesis guiding the study was that no substantive differences would emerge between…

Examines the effects of using interactive digital video on student learning and attitudes in an introductory physics course. Results indicate that sophisticated instructional video software can be perceived by students as easy to use and effective. The software can also be used to promote active learning. Contains 48 references. (Author/JRH)

Explores the effects of an integrated video media curriculum enhancement on students' achievement and attitudes in a high school chemistry course. Findings reveal significantly higher achievement scores for students who experienced the course enhanced with integrated video media.
