Accounting for verbal reports requires explication of the mechanisms by which the reports are generated and influenced by experimental factors. We discuss different cognitive processes underlying verbalization and present a model of how subjects, when asked to think aloud, verbalize information from their short-term memory. (Author/GDC)

This study examined whether a relationship existed between field-dependence-independence and scientific attitudes of sixth-grade students in SCIS. Findings indicated that such a relationship was not statistically significant. (Author/DS)

Summarizes experiments indicating that a basic key to learning is the development of concepts of pattern recognition and the appropriateness of using a particular theorem. (Author/SK)

This discussion of information structures in written texts describes how linguistic analysis of short published reports leads to the presentation of an algorithm that depicts the problem-solving process in terms of a series of evaluative questions. (Author/CHC)

Research on levels of questioning and their effects on learning is reviewed. It is shown that higher level questions facilitate reproductive and productive knowledge, but the reasons why are not clearly understood. An information processing model which accounts for question level effects is discussed. (MH)

Compares the production of speech and sign: the approaches used in research, the cognitive processes involved, and the output timing mechanism. (AM)

The study examined 120 bilingual Mexican American and 24 monolingual Anglo American (pre-K-1) children's comprehension of 26 relational concepts by manipulating the natural language to separate and evaluate cognitive and linguistic variables. Six hypotheses were proposed as operating principles applicable to, but not necessarily limited to,…

Methods for teaching writing skills are described. Techniques include utilizing writing exercises as they present themselves in content courses, establishing an honor system, individualized instruction, and repeated practice sessions focusing on specific writing skills. (LH)

The author describes activities he uses with secondary school science students to learn about their reasoning. (Author/SA)

Ratcliff's theory of memory retrieval which posits parallel processing and Sternberg's serial processing explanation of memory scanning are reviewed and contrasted. Discrepancy between the two theories may arise because they focus on different aspects of the data. If scanning without comparisons takes place, the two views may be reconciled.…

Discusses the applications of Piaget's theory of cognitive development to elementary and junior high school science teaching. Topics include planning concrete experiences, inductive and hypothetical deductive reasoning, measurement concepts, combinatorial logic, scientific experimentation and reflexive thinking. (SA)

Investigates age differences in selective attention in a coded visual search task where subjects were given different types of information about target location before trial onset. (Author/SS)

Reviews the effects of source credibility and other variables in the communication process, showing how they work in cognitive response and attribution theories. Develops and posits a theoretical position that links the two types of theories. (RL)

A novel cognitive style distinction is introduced: the Assimilator, who stretches established principles to meet novel tasks, and the Explorer, who seeks novel solutions even when established principles would serve. The assets and liabilities of each problem-solving style are considered and results of a validation study presented. (Editor/SJL)

Findings reveal that students who are skillful in perceptual restructuring attain significantly higher mean achievement scores in science, in knowledge of science, and in the ability to apply what has been learned in unfamiliar contexts than students with low structuring ability. (Author/MA)
