Suggests that schools include technology in the curriculum; the emphasis should be on the analysis of real problems. (LS)

Describes various elementary school activities using a loaf of raisin bread to promote inquiry skills. Activities include estimating the number of raisins in the loaf by constructing histograms of the number of raisins in a slice. (MLH)

Discusses the fact that when the materials or interactions used as a basis for a science activity posses a high degree of familiarity, the student may rely on past experience rather than on gathering data to use in making judgments. In such cases, a simple request for observed evidence should be made. (MLH)

Suggests introducing values clarification into the classroom as a way to help students learn to make value judgements on contemporary issues. (BR)

An approach which is designed to help students better understand the utility of models in understanding and doing physics, specifically in a course in light and color, is described in this paper. Explanations are given and illustrations are provided of an analogue model of waves which assist in the creation of an abstract model to deduce Snell's…

Evidence from video tapes of experts thinking aloud and using analogies in scientific problem solving is presented. Four processes appear to be important in using an analogy: (1) generating the analogy; (2) establishing confidence in the validity of the analogy relation; (3) understanding the analogous case; and (4) applying findings to the…

This paper discusses some means by which one might answer the question of "What makes problem solving hard?" In order to facilitate the investigations required to answer this question, a model of problem solving is needed. From some simulated solutions to a physics problem, several problem solving processes used by students are…

Seventy-one college general biology students were taught a unit in Mendelian genetics by the traditional lecture method. Emphasis was placed on meiotic formation of gametes, dominance, segregation, and independent assortment. The Punnett square model was used for all practice problems. While using this model, students were asked to: (1) identify…

This study investigated how students processed information obtained by reading a passage related to inertial reference frames. Two groups of 10th-grade students (one group consisting of students identified as potential National Merit Scholars and another consisting of students enrolled in level-I biology) read a science text passage and answered a…

Outlines a model which describes the processes that a learner goes through in attempting to solve problems, and suggests ways to assist students in reaching a solution when they are confronted by an apparent impasse. (JR)

Traces the historical development of the university instructional laboratory. Describes the basic components of a problem-oriented laboratory program and identifies four forces that may dictate instructional change in the future. (GS)

The theme of the seventh yearbook of the Association for the Education of Teachers in Science (AETS) involves the relationship of psychology of teaching thinking and creativity as this activity is performed in a science education context. Eleven chapters follow a foreword by Jean Piaget and the reproduction of Part I of "The Central Purpose of…

A problem is presented that teaches the engineering student or practicing engineer the behavior of Hooke's joint, a widely used mechanism for transmitting rotary power in mechanical equipment. Also provided by this problem is an exercise in analog programing which utilizes nonlinear computer elements. (Author/CS)

This teacher's guide contains activity modules designed to help explain present energy use patterns and basic concepts in energy use. Also covered in the manual are suggestions for energy-related field trips and strategies for successfully conducting such trips. The activities are presented according to grade level, including primary,…
