A problem-solving approach is developed for secondary or college students to estimate the number of piano tuners in a large city. The answer and method are analyzed for appropriateness. Four similar problems are suggested. (DC)

Describes a project which aims at improving human interaction in a deductive logic course via the use of a proof-checking computer program. Shows that the use of computers in education need not separate teachers from students, but rather can provide information concerning student needs and supply opportunities for addressing those needs both…

Examines successful/unsuccessful distinctions between novices and experts in problem solving in terms of genetic knowledge, use of production rules, strategy selection, use of critical cues, use of logic, understanding of probability, and the thinking process itself. Suggests five implications for genetics instruction and provides three problems…

Discusses the implications of Wallis Suchting's comprehensive search for a definition of the nature of scientific thought for helping students develop scientific thinking skills and an adequate understanding of the nature of science. Discusses implications that relate specifically to the science education community's current conceptions of science…

Students (n=46) were assigned to one of three instructional groups (descriptive, question design, and hypothesis testing) to test the hypothesis that descriptive learning cycles are not sufficient to stimulate students to reason at a formal operational level. Analyses indicated that the hypothesis-testing group exhibited a significant increase on…

A study examined the effects of rationale emotive psychoeducational procedures on aspects of mental health with 22 Australian fourth grade girls and 14 control subjects who received an attention control intervention. Rational emotive education increased perceptions of internal locus of control and rationality but did not reduce trait anxiety.…

A study at Cleveland State University (Ohio) compared the effectiveness of conventional mathematics instruction given to 190 students with an alternative course in mathematical reasoning given to 120 students as preparation for a required course in real analysis. Results show the alternative method effective in raising both pass rate and grades in…

This study examined the problem-solving protocols of 21 students in a grade 11 enriched physics course as well as 3 adult "experts" in physics. Experts and high performing students made more correct metastatements and more references to prior knowledge than did average performing students. (DB)

The soliciting-and-reacting-moves questioning technique used in science classrooms is described. The importance of using both higher-order and lower-level questions during a lesson is discussed. An example of a dialogue between a student and teacher using this technique is included. (KR)

A primary math activity teaches students counting and classifying using a book about a mother and child who tour a farm at midnight. An intermediate math activity teaches logical reasoning through a story problem in which students must use information from a story to figure out an answer. (SM)

Focuses on the significant connection between logic and information retrieval. Introduces the formalisms used in logical models for information retrieval, shows the use of logic to build the models, and presents a brief overview of some of the current logical models in information retrieval. (Author/AEF)

Compares two groups of preschool children to assess the effect of children's counting ability on their ability to reason about numbers. Describes the research design and the set of expected possible outcomes. Reports results in light of these predictions, concluding that counting ability is not necessary for number-relevant operations. (DSK)

Twenty-nine children with learning disabilities (LD) in grades 2 and 4 through 7 were compared with children without LD for their development of proportional structures of thought. Significantly fewer children with LD had constructed second-order logical structures necessary to act on problems using multiplicative and preproportional reasoning.…

Asserts that becoming adept at understanding the logic of subjects, issues, and questions is a competency that, once learned, becomes a foundation for highly skilled and practical teaching and learning. Promotes the model of teaching students to seek the logic of things through the logic of science. (VWC)

This study investigated whether rotating virtual reality (VR) three-dimensional (3D) objects had a positive effect on the ability of 21 deaf and hard-of-hearing children to use inductive processes when dealing with shapes. Results indicated that practice with VR 3D spatial rotations significantly improved inductive thinking when compared with a…
