Focuses on the relationship between environmental opportunities for social interaction, experienced internal conflict, and upward stage change in moral reasoning. Also examines the extent to which the dilemmas which constitute Form A and Form B of Kohlberg's Moral Dilemmas produce comparable stage scores. (Author/MP)

Four studies tested the hypothesis that collection structures are easier than classes in numerical reasoning tasks. With perceptual input constant, the collection labels in contrast to the class labels promoted children's insight into certain numerical principles and facilitated the use of these principles in a variety of numerical tasks.…

Investigates the effect of various strategy-modeling techniques on the performance of both young children and elderly adults on the 20 Question Task. (Author/MP)

Presents some arguments for the importance of nature conservation which are intended for British science teachers. A study which investigates students' understanding of a concept is also included. (HM)

Discusses a study designed to determine whether early reading instruction constitutes a positive factor in the cognitive development of children. The subjects for this study were 25 children in a nursery school in Macerata, Italy. (CFM)

Replicated the Clarke-Stewart (1973) cross-dimensional study of mother-child interaction using different children at different ages and in a series of four different samples. Variables included measures of children's cognitive, language, and social development and mothers' attitudes, ability, and behavior, assessed in standardized tests,…

Discusses the cognitive outcomes of physics laboratory exercises and suggests three types of experiments which should be added to those normally used in physics courses. (HM)

Proposes that cognitive developmental stages can be accounted for in terms of information processing factors which limit the highest level of cognitive system which children can attain at any given age. Delineates four progressively more complex levels of cognitive mediation of the environment. Two experiments which support the developmental model…

Investigates how intellectual development, IQ, and achievement of 92 high school biology students were affected by inquiry teaching methods. A pre-post-test design of four parameters (Cognitive development, content achievement, inquiry skills achievement, and IQ) was used. Results show that inquiry teaching produces significant gains in all…

Presents specific guidelines which content-oriented science teachers can follow in order to develop subject-matter comprehension, decision-making skills, and values/moral clarification and reasoning processes in their students. (Author/HM)

This paper was presented at the Southeast Asian Workshop on new trends in the selection of content for chemistry curricula. The chemistry curriculum project developed by the Institute for the Promotion of Teaching Science and Technology (IPST) of Thailand was discussed. (HM)

A study of 11- and 12-year-old girls indicates that either of two training procedures, method training or dimension training, can aid in the transition from concrete operational to formal operational thought by promoting a hypothesis-testing attitude. (BH)

Discusses the importance of questioning as a means of achieving independent intelligence, critical thinking, and learning to learn. Advocates a science program that encourages investigation, discovery, and questioning. (MA)

A reasoning test was administered by all science teachers at a high school. This report presents the results of the test and explains how this information can be used to improve teaching. (BB)
