This paper argues that the introduction of the scientific method in the very rich environments of the natural sciences or human sciences may disguise the process and create difficulties for students because of the multiplicity of variables involved, whereas the variables present in a mathematical context can be readily manipulated and their…

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…

The Information Age has been shaping the conception of thinking in education through the capability of computerized problem solving, through the resulting application of the information processing model to human thinking, and through the theories emerging from other cognitive science research in metacognition, construction of knowledge, and…

Compares experts', advanced students', and novice students' use of genetics knowledge to generate and test hypotheses while solving genetic pedigree problems. Reports that experts identified more critical cues, tested more hypotheses, were more rigorous in the falsification of alternative hypotheses, and were more flexible to their solving…

Implications for science curricula and instructions of new perspectives on scientific knowledge, on nature of evidence, and on how knowledge changes are considered. Argues that much of science education is mired in positivist assumptions and suggests ways in which science instruction can promote a more appropriate epistemological attitude and…

Some central issues in discussions of creative processes in science are: (1) the mechanism(s) by which hypothesis formation takes place; (2) the sources of new knowledge during hypothesis formation; and (3) the "Eureka" versus steady accumulation (accretion) issue concerning the pace of change during hypothesis formation. This paper…

This document focuses on evidence from problem solving case studies which indicate that analogy, extreme case analogies, and physical intuition can play an important role as forms of nonformal reasoning in scientific thinking. Two examples of nonformal reasoning are examined in greater detail from 10 case studies of "expert" problem solving.…

Examines the rise of the general science course and its implications for the reform of secondary science education. Concludes that while recent reforms emphasize the personal and social character of science and the use of the scientific method, they will not necessarily make students more scientifically literate or train them to think about…

Documents the educational use of spreadsheets through a description of exploratory work which utilizes spreadsheets to achieve the objectives of Conway's Game of Life, a scientific method game for the development of problem-solving techniques. The implementation and classroom use of the spreadsheet programs are discussed. (MBR)

Criticizes the Mitchell and Lawson (1988) report from the viewpoint of individual interview method. Provides Lawson's reply to the comment by showing differences in research philosophy and methods. (YP)

A number of studies have reported that there is a strong tendency to ignore base-rate information in favor of individuating information, except when the former can readily be incorporated into a causal schema. In this study, students in eight undergraduate classes were given problems in which the base-rate information was either causal or…

One of the difficulties encountered by novice problem solvers in introductory physics is in the area of problem solving. It has been shown in other studies that poor problem solvers are affected by the surface aspects of the problem in contrast with more efficient problem solvers who are capable of constructing a mental model of the physical…

The purpose of this study was to determine whether an electronic geoboard, a computer-software program, could be used to assess youngsters' ability to discover facts and relationships in an unlabled and ambiguous situation. Subjects--108 children, ages 6 to 12--were enrolled in grades 1 to 6 in Norwood, New York. The electronic geoboard served as…

During the summer of 1986 a conference funded by the National Science Foundation (NSF) was organized to assess the current state of cognitive research on the psychology of physics problem solving, and to examine the needs of physics instructors and instructional designers that must be addressed by a psychological theory of physics problem solving.…

The Test of Integrated Process Skills (TIPS) was administered to 667 students in grades 9-12 who were registering to participate in a regional science Olympiad on a southern university campus in February 1988. Each student's score on the test was correlated with subsequent performance in one or more of the 11 Olympiad events. Of the 667 students…
