Urhahne, Detlef; Nick, Sabine; Schanze, Sascha – Research in Science Education, 2009
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…

Ferk, Vesna; Vrtacnik, Margareta; Blejec, Andrej; Gril, Alenka – International Journal of Science Education, 2003
The purpose of the investigation was to determine the meanings attached by students to the different kinds of molecular structure representations used in chemistry teaching. The students (n = 124) were from primary (aged 13-14 years) and secondary (aged 17-18 years) schools and a university (aged 21-25 years). A computerised "Chemical…
