This study describes strategies fifth- and sixth-grade children used to solve the problem of determining how to control a "vehicle" they "drove" by pressing particular keys on a computer. The problem involves identifying or discovering a set of cause-effect relationships. (Author/JN)

Explores the differences between deep and surface approaches to learning science. Findings indicate that the deep-surface learning differences fall into five categories: (1) generative thinking; (2) nature of explanations; (3) asking questions; (4) metacognitive activity; and (5) approach to tasks. Suggests that teachers can encourage a deep…

Reviews an investigation of the effects of problem format and the number of independent variables on the responses of students to a control of variables reasoning task. Results indicate that adding independent variables to a control of variables reasoning problem leads to an overload of working memory which affects performance. (ML)

Describes the use of an intervention stressing the metacognitive, regulatory, and strategic aspects of knowledge co-construction. Finds that eighth grade students who received the intervention gained in metacognitive knowledge about collaborative reasoning and ability to articulate their collaborative reasoning processes compared to students in…

Investigates the effect of increase of the M demand of chemistry problems, having the same logical structure, on performance of students having different functional M capacity, cognitive style, and formal operational reasoning patterns. (Author/YP)

Presents data which leads to the construction of a response to the question of how different phases of the learning cycle influence physics students' content achievement and attitudes. Discusses the importance of the learning cycle in science instruction and the strength of using contrasting techniques (qualitative and quantitative) in research.…

Reviews the neural modeling principles of learning, perception, cognition, and motor control, discusses their applications to sensory-motor problem solving, and explores possible relationships between that pattern of problem solving and aspects of higher order formal operational problem solving. Cites implications for science education. (ML)

Explores the influences of text structure on students' conceptual change. Case studies were conducted and results showed that individuals used refutational text to change their alternative conceptions and acquire new concepts. Findings indicate that refutational text does cause cognitive conflict. While refutational text is effective for groups,…

Examines the hypothesis that there are preliminary stages in problem solving that are often neglected in teaching chemistry. Discusses correlations calculated between the student's ability to handle disembedding and cognitive restructuring tasks in the spatial domain and ability to solve chemistry problems. (TW)

Presents study findings which explored the effect of teacher reasoning level and teaching style preference on improvement in student-reasoning ability. Reports that students of concrete operational teachers and of inquiry teachers showed greater gains in reasoning ability than students of formal operational teachers and of expository teachers. (ML)

Examined are two aspects of science education--the nature of science and curriculum reform. Contemporary views on the tentative nature of science and a generative model of learning are synthesized. (KR)

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)

Discusses the value of studying errors made by students in the process of learning science. Addresses 20 research questions dealing with student learning errors. Attempts to characterize errors made by students and clarify some terms used in error research. (TW)
