In two experiments, high school students read and listened to either a signaled or nonsignaled expository passage. Signals consisted of preview sentences, underlined headings, and logical connective phrases. Results indicated a pattern in which the signaled groups performed better on recall of conceptual information and on generating high quality…

Subjects listened to a short science passage one, two, or three times. Overall amount recalled increased with number of presentations, but recall of conceptual principles and related information increased sharply with repetition, whereas recall of formal equations and concrete analogies did not. Advance organizers functioned similarly. (Author/PN)

This study concerns the role of structural properties of scientific prose: description of relations and explanation of mechanisms. The latter is isolated as a characteristics related to creative problem solving. (Author/GK)

Discusses five instructional strategies for increasing the meaningfulness of technical or scientific information. These include organization of prose, use of concrete analogies as advance organizers, use of inserted questions in prose, elaboration activities such as note-taking and discovery learning. (JN)

Techniques are provided for distinguishing explanative information from other types of information in science prose, including the structural method, the logical method, and the empirical method. Research is then provided concerning techniques which increase the subjects' recall of explanative information, and thus the subject's problem solving…

Five instructional techniques for increasing the meaningfulness of technical or scientific information are summarized: (1) organization of prose; (2) use of concrete analogy and advance organizers; (3) use of inserted questions in prose; (4) elaboration activities such as note taking; and (5) discovery learning. Research on each technique is…
