The study investigated retention of gains in reading/language skills after one year by 378 eighth-grade students in 18 health studies classrooms. Six classrooms were assigned to each of three groups, two experimental and one control, taught by health science teachers who were: (1) trained in reading/language techniques; (2) not trained in…

This field experiment begins to build a theoretical framework for exploring the effects of media characteristics on subjects' understanding and integration of information. Students in two eighth-grade science classes wrote term papers with one class using a print encyclopedia and the other an electronic encyclopedia to conduct their research. A…

Focusing on the achievement and motivational effects of analogies of varying enrichment levels when used with abstract, unfamiliar, and difficult content, this study examined their effects on instruction at the recall and application levels using content consisting of both concepts and principles. The subjects were 123 eighth-grade science…

This field study examined learning effects attributable to instructional design characteristics when eighth-grade science students used a print encyclopedia or a videotex version of the encyclopedia to write term papers. Results suggest that specific effects of instructional design characteristics of a delivery system are of a limited nature. (MBR)

This study examined the effects of the type of adjunct questions (use-a-generality, remember-a-generality, and remember-an-instance) and the position of these questions either before the relevant text passage (pre-questions) or after it (post-questions) on the three corresponding performance levels of learning. The subjects were 74 eighth-grade…
