Recent research in science education examines learning from four foci: (1) concept learning; (2) developmental; (3) differential; and (4) problem-solving. These perspectives provide a framework for identifying mechanisms of change in knowledge/thinking processes. In-depth coverage of several science topics may benefit students more than fleeting…

Empirical and theoretical evidence is presented to support the conclusion that improvement of learning ability is an important and viable educational goal. The improvement of learning ability necessitates development not only of specific learning skills, but also an executive control mechanism that automatically accesses and combines learning…
