The concept of the mole and its relationship to chemical algebra is difficult for many high school chemistry students to master. This paper describes a study of the use of proportional reasoning when teaching mole relationships and its effect on developing critical thinking skills. The Test of Logical Thinking (TOLT) was used as a pre- and…

The purpose of this research was to provide information about gender-related worldview structures, among college students, that can inform the instructional decision making process. Information was generated in a logico-structural investigation of the interrelationship of gender, interest in science, and concept of nature. The strength of the…

Six tips for increasing student problem-solving skills are offered in this teacher fact sheet. Puzzles and simulations matched to student mental maturity and general knowledge are recommended as activities for helping students think more flexibly and practice higher order thinking skills. In addition, four suggestions are given for controlling…

The hypothesis for this study assumed that subjects who received a diagram representing the structural relationships of a story would be more likely to solve a new and analogous problem than subjects who received two analogs without a diagram. The 151 graduate students who acted as subjects were randomly assigned to one of four treatments: one or…

Because analogical reasoning plays a major role in content area reading comprehension, teachers should learn to teach analogy-solving skills and to identify the kinds of difficulties some elementary students will have in solving them. Analogies are statements of relationships wherein one term is similar to another term. Relationships in analogy…

This paper takes the position that logical knowledge is distinct from conceptual and procedural knowledge and can make a unique contribution to the understanding of knowledge acquisition. This view of logical knowledge departs from the traditional Piagetian view of stages and the overriding view of logic as the sole means of constructing new…

This paper focuses specifically on the reasoning skill called proportional reasoning. Areas addressed include: (1) a definition (providing examples of direct and indirect proportional reasoning); (2) the development of proportional reasoning (discussing survey results of students logical reasoning abilities); (3) planning for the future (proposing…

Reported are the findings of five descriptive studies in which the Group Assessment of Logical Thinking (GALT) was used as measure of logical thinking. Specifically, an attempt was made to determine how reliably the GALT measured logical thinking abilities and how well it predicted academic achievement. The reliability coefficients on the GALT for…

One approach to the study of problem solving is to observe how people with different skills (novices and experts) solve problems by collecting and analyzing protocols and formulating models to obtain solution processes. Individual differences are subsequently explained by the differences in the knowledge possessed, as embodied by the sets of…

Conducted in Swaziland in 1984 and 1985, this research study explored children's logical thinking skills. One of the primary elements examined was the relationship between previous preschool experience and the child's ability to perform logical thinking tasks. The study consisted of six Piagetian tasks given to 400 children, preschool through…

An analysis is presented of the latest findings from psychology and education on how children acquire complex thinking skills and learn to reason, and how the schools can teach such skills more effectively. This paper reviews previous research, highlights successful learning strategies, and makes specific recommendations about problems and…

A broad range of well-structured problems--embracing forms of diagnosis, catalog selection, and skeletal planning--are solved in expert computer systems by the method of heuristic classification. These programs have a characteristic inference structure that systematically relates data to a pre-enumerated set of solutions by abstraction, heuristic…

The purpose of this study was to describe student perceptions within high school classes in biology and chemistry over the course of a school year. The sample consisted of 435 high school college preparatory science students who were enrolled in 44 different biology and chemistry classes in central New York State. Measurements of attitude toward…

The level of thinking that is characteristic of the typical college freshman and the skills needed by college science courses are addressed, and the Development of Reasoning in Science project (Project DORIS) at California State University, Fullerton, is described. While the typical college freshman functions at the concrete level of thinking,…

A thinking-skills course at Montana State University is described, along with recent issues concerning the potential effectiveness of such courses. Advantages and disadvantages of different designs for studying the effects of thinking-skills training are also considered. The focus of the course is: hypothesis formation and evaluation, problem…
