The application of technology in classroom settings has equipped educators with innovative tools and techniques for effective teaching practice. Integrating digital technologies at the elementary and secondary levels helps to enrich the students' learning experience and maximize competency in the areas of science, technology, engineering, and…

Described is the Cognitive Acceleration through Science Education (CASE) project in Great Britain. The project is investigating the possiblilty of accelerating the rate at which secondary pupils' logical thinking develops by using the science curriculum. A pilot project and parts of the curriculum are discussed. (RH)

Determined is the logical reasoning necessary to construct line graphs including a straight line with a positive or negative slope and an exponentially increasing curve. The responses of subjects (grades 6-12) were classified into one of nine categories fitting with Piagetian operational structures. (Author/YP)

Discusses the human brain's specialized perception/expression and information processing systems as they relate to student learning. For high school students in the formal reasoning stage, it is suggested that teachers provide instruction based on mental exercises to develop problem-solving insight. (DH)

Reviews findings from three diagnostic studies which focused on the problem of tautological explanations. Includes a report on a teaching intervention strategy which resulted in the improvement of pupil performance. Suggests that avoidance of tautology can be taught. (ML)

Math and science instruction now often includes more brief, informal writing exercises, sometimes completed in class, as a means of helping college students think more clearly. While writing skills are not emphasized, student writing often improves as a by-product. (MSE)

Presents an activity using logic mystery stories that students solve by asking yes-or-no questions. Helps students discover the reasoning behind good questioning and provides for practice with instant feedback from the teacher. Includes sample stories. (MKR)

Investigates the effect that manipulation of the extent of formal reasoning required for solving chemistry problems has upon student performance, and presents a cognitive model for the qualitative analysis of that effect. Concludes that the developmental level of students is the most important predictor of problem-solving success given significant…

Characteristics of successful and unsuccessful problem solvers in categorization tasks are examined in this study of undergraduate students. Findings are reviewed of the categorization and solution tasks undertaken by a group (N=21) of science majors at a private university. The subjects were classified as either successful or unsuccessful in…

Proposes that there is a universal method for all realms of knowledge. Reviews Descartes's definition of the universal method, the engineering definition, and the philosophical basis for the universal method. Contends that the engineering method best represents the universal method. (ML)

Describes a model that teaches a problem-solving process and provides students with the opportunity to practice, develop, and enhance their thinking skills. States that applying learning to real problems is needed to increase a student's thinking ability. Provides diagrams of the problem-solving cycle and levels of thinking. (RT)

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…

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…

Discusses a study which compared differences in ratio construction made by high school freshman and junior students. Reports that more freshmen than juniors selected solutions involving one variable, whereas juniors chose solutions that coordinated two variables in a mathematical or verbal rule. Reviews implications in problem solving and concept…

This study was developed to provide advice to teachers on how to use rules in teaching experimental design in science classes. A review is presented on the use of rule in science teaching and the effects of instructional treatments are assessed on Canadian high school students' skills of experimental design. (ML)
