In a previous study (Watson, 1960), college students were told that a three-number string ("2, 4, 6") conformed to a rule and that they had to guess the rule by proposing other three-number strings; they were then told whether each guess was right or wrong. However, it was suspected that, since the subject's hypothesis was falsified by…

Vygotsky argued that children's development is most likely to occur when, in the course of collaboration, assistance is provided within their zone of proximal development--the distance between what a child can achieve independently and what he or she can do with the assistance of a more competent member of their culture. This paper reports the…

Presents four guidelines for teaching quantitative problem-solving based on research results: analyze difficulties of students, develop a system of heuristics, select and map key relations, and design instruction with proper orientation, exercise, and feedback. Discusses the four guidelines and uses flow charts and diagrams to show how the…

Reports a study to determine if the formal capabilities of 81 elementary education preservice teachers would be enhoused from problem solving instruction with manipulative feedback or with pictorial feedback. Results indicate the manipulative mode was clearly superior in student attitudinal responses and achievement. (SL)

The authors investigated whether guidance and reflection would facilitate science learning in an interactive multimedia game. College students learned how to design plants to survive in different weather conditions. In Experiment 1, they learned with an agent that either guided them with corrective and explanatory feedback or corrective feedback…

Two studies were conducted to clarify the influence of experiences and aptitudes on male-female differences in formal thought. Participants were 788 seventh-, ninth-, and eleventh-graders in three school districts differing in location, socioeconomic composition, and course offerings. Formal thought was measured with tasks involving proportional…

Reports on a study that investigated the effects of various instructional practices on programming proficiency focusing on characteristics of Pascal classes. States that instructional practices involve extensive on-line access, explicit instruction, and extensive feedback. (ML)

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)
