Reviews a study which examined the effects of types of feedback and diagnostic testing on learning from text aided by a diagnostic/prescriptive instructional strategy. Significant differences in instructional time and learning efficiency were observed from participating undergraduates (n=150) which were not linearly related to feedback complexity.…

Reports on a study that assesses the effects of the application of visual information-processing theory to the design of a laboratory manual for chemistry. Focuses on the effects on content learning, practical skill mastery, and attitudes of university students enrolled in a general chemistry course. Contains 41 references. (DDR)

Identifies and describes the differences in the problem-solving methods used by faculty teaching introductory chemistry and students enrolled in an introductory chemistry course. Results indicate that students correctly solve algorithmic-mode problems more frequently. Contains 33 references. (DDR)

Examines congruence between science content structure of instructional materials and students' structural representations before and after science instruction. Eighth-grade science students (N=30) were given concept-structuring tasks before and after studying instructional materials to assess changes in student structural representations.…

Reports on students' study and drawing of five electronic circuit diagrams. Concludes that the success of the students depended upon the amount of detail in the instructional diagrams. (RT)

Uses two studies to examine developmental and task effects in estimation problems. Results are discussed in terms of student and task characteristics and the implications of such variables on information processing model of learning. Implications for science teaching, learning problem diagnostics, and science curricula are also discussed. (TW)
