Discusses children's conceptions of dynamics, comparing them to those of scientists and examining how they are acquired. Also discusses alternative aims of teaching dynamics at the elementary and junior high school levels, providing instructional strategies to achieve these aims. (JN)

Discusses a view of observational competence which consists of three proficiencies--proficiency in making observations well, in reporting them well, and in assessing correctly the reports of observations. The conception offers detailed sets of conditions for observing and reporting observations and a set of principles for assessing observational…

Describes a procedure for starting tree cuttings from woody plants, explaining "lag time," recommending materials, and giving step-by-step instructions for rooting and planting. Points out species which are likely candidates for cuttings and provides tips for teachers for developing a unit. (JM)

Presents a lesson plan format which enables teachers to incorporate simulations into their classroom activities. Particular attention is given to planning for the interactions students should have while engaged with the simulation. Includes cognitive and affective results obtained from trials of the format with elementary/middle school students…

Uses examples related to a head of cabbage to discuss: (1) sensory development in children; (2) the integration of sensory and cognitive involvement; and (3) a child's mode of exploring and discovering. Also discusses why science curricula need to be organized around a paradigm that is holistic. (JN)

Provides examples of science activities in which children use their senses in manipulating objects and ideas. Suggests that these and other activities be extended to help children deepen their understanding of scientific concepts. (JN)

Results from three cognitive tests revealed few sex differences among 11-year-old students (N=2065). Neither question style (multiple-choice or structured) nor content (masculine or feminine) has any great effect on sex differences in performance. However, boys performed markedly better than girls on tests of spatial ability and mechanical…

Presents a list of published (or soon to be published) computer assisted instructional programs for biology. The programs vary considerably in terms of intended age/ability level, complexity and depth, and in content. No attempt is made to judge the quality of items in the list. (JN)

Describes chemistry courses offered as part of a residential summer enrichment program held at the University of Northern Colorado. A list of elementary and advanced chemistry activities completed during the courses is included. (JN)

Investigated whether examining materials from several perspectives had greater effect on development of projective spatial abilities than examining materials from a single perspective. Results using 105 students (56 females, 49 males) favored the former approach. Also, sex was determined to have no direct effect on development of projective…

Discusses the need to adapt science education objectives to the objectives and expectations of students. Proposes a framework for the study of science which has a firm knowledge basis and gives a valid description of science in our contemporary society. (MLH)

Outlined are 10 experiments, demonstrations, and helpful hints for elementary science classes utilizing common, inexpensive materials. Topics include mixing colored lights, detergents, weightlessness, solar energy, and hydrogen gas. (SL)

Presented are objections to the introduction of integrated science curriculums in elementary and secondary schools. (SL)

Described is the integration of individual student inquiry investigations into a seventh grade life-science course. Student projects and problems encountered are discussed. (SL)

Presented is an annotated bibliography of reference materials on the maintenance of plants and animals. (SL)
