The author presents an analysis of alternative views about why students should learn science, shares some anecdotal impressions about the heuristic potential of the concept "curriculum emphases" in a practical setting, and examines some problems related to teaching science to early adolescents. (Author/PB)

Compares the effectiveness of an Extended Discretion (ED) laboratory approach (exercising independent judgment) to a BSCS Green Version laboratory program. Results from 10 classes taught by five teachers, each teaching one experimental and one control group, favor the ED approach on a number of measures. (Author/JN)

Reports long-term effects of intensive instruction in the cue attendance or hypothesis generation on open-exploration behavior of 120 ninth graders. Five dependent measures included: number of observed details; number and quality of hypotheses; and number and diversity of questions. Results suggest long-term benefits. (Author/JN)

Describes materials from various science programs having confluent attributes (merging cognitive and affective aspects of teaching and learning). Presents guidelines and instructions for preparing eight confluent activity cards suitable for use outdoors. (SK)

Describes research focusing on factors that might predict success in a Basic Science Skills course for preservice elementary teachers (N=113). (DS)

Determined the effect of using previsit instructional materials on student learning for a museum field trip experience. Ten earth science classes were assigned to experimental (instruction over field trip) and control (normal class instruction) groups. Found previsit instructional materials significantly increased student test scores. (DS)

A model is given of the Comprehensive Assessment and Program Planning System (CAPPS) in Indiana. The purpose of diagnostic/prescriptive teaching is discussed within the context of this model. (SA)

Reported is the production of an instructional methodology harmonizing with Piagetian theory and enabling teenage students, including those initially mismatched to the task, to understand the mole, as revealed by their performances on a test of basic skills considered fundamental to that concept. (DS)

Presented are critical comments on the British Schools Council, Science Committee, Programmes of Work 1980-82, and financial allocations to various curriculum and instructional projects. The author's personal frustrations while serving on the Science Committee are also given. (JN)

Describes a number of laboratory experiments using woodlice as experimental animals. Includes topics such as physiology of water relations, behavior, and rhythmic activity. (CS)

Describes methods for collection, culture, observation, and making permanent stained preparations of the protozoan vorticella. Suggestions are made for experiments to investigate growth, reproduction, settlement, ecology, feeding, and osmoregulation. (CS)

In Bossier Parish, Louisiana, a part of the bayou country is used as a classroom and laboratory for the district's schools. Through collecting live specimens and asking questions of the tour guide instructor, students (grades K-12) learn about science and the environment and enjoy the nature center's recreation facilities.

Faculty of the New York University School of Education, Health, Nursing, and Arts Professions describe curricular changes since World War II in subjects that have traditionally been included in high school studies: English, math, social studies, science, the arts, and foreign languages. (Editor)

Explored the relationship between high school students' (N=37) performances on the Tomlinson-Keasey and Campbell paper-and-pencil test of formal operations and a set of traditional, individually administered, Piagetian developmental tasks. Correlations between the traditional, formal operations tasks and paper-and-pencil tests were low. (Author/DS)

Describes several consumer science activities useful for introducing process skills for the middle/junior high school student. Activities described include testing laundry detergent effectiveness for stain removal, comparison of quantities in fast foods, and various activities concerning tests of product claims. (DS)
