Many studies in the field of chemical education have emphasized the fact that students at secondary level have considerable difficulties in mastering organic chemistry contents. As a result, they choose to learn these contents in a "rote" way. Taking this fact into consideration, the first aim of our study was to help students in…

In order to investigate the effects of sequence and synthesis in the teaching of taxonomically-related concepts, a study was conducted in which 27 students from Syracuse University were asked to examine printed instructions dealing with kinds of sailboats and then to respond to a test based on those instructions.

This study investigated the effects of different structures of a synthesizer and formats of the generality component on the application and remember levels of learning. Seventy-three undergraduates participated. Four treatment groups were formed by combining two types of structure (complete versus partial) with two types of format in generality…

For teaching such skills, two questions have not been adequately investigated: (1) how the operations comprising the skill should be sequenced, and (2) the relationships among the operations that need to be taught. This investigation entailed four studies on different types and lengths of basic…
