In a series of three experimental studies, the effectiveness of three-dimensional computer simulations to aid the understanding of chemical structures and their properties was investigated. Arguments for the usefulness of three-dimensional simulations were derived from Mayer's generative theory of multimedia learning. Simulations might lead to a…

Results of various studies suggest that multimedia "case methods" (activities associated with case documentaries) have many benefits in university-based teacher education contexts. They can, for example, help to "bridge the gap" between perspectives and practices held by academic teacher educators and those held by student-teachers--who may adhere…
