Lott, Gerald W. – Journal of Research in Science Teaching, 1983
Two areas of research were explored in this meta-analysis: comparison of inductive versus deductive approaches and use of advance organizers. The study involved 128 characteristics for 39 studies spanning the period from 1957 through 1980. Coding variables included 57 concerned with treatment features and 12 with outcome attributes.
