Determined: (1) whether students thought of magnetic poles as exerting forces directly on electric charges and (2) the specific strategies students used to make predictions about the forces acting on electric charges in two problem situations. Implications for instruction are considered. (JN)

Acquisition of sentient-nonsentient distinction in 48 children between four- and seven-years-of-age occurred later than animate-inanimate distinction. The children's use of naturalistic or nonnaturalistic explanations depended on the logical nature of events in which objects were involved rather than familiarity with objects themselves. Ability to…

Examines the relationship of grade level to children's ability to make musical discriminations when elements are presented simultaneously. Utilized a brief instructional period, listening tests, and singing tasks. Results indicated significant differences between grade level, types of discrimination, and musical interactions. Includes statistical…

The strength of intuitive knowledge is illustrated by the difficulty that individuals have in trying to restructure student misconceptions. In order to harness this power, intuition must be developed within the context of each new concept to be taught. An experiment with one possible approach to this instructional problem is described and…

By varying task requirements within a common procedural framework, four experiments established conditions under which children exhibit different understandings of life. Overall, results suggested that even four- and five-year-olds know that people and other animals are alive and that almost all "inanimate objects" are not. (Author/RH)

Meta-analysis techniques were used to analyze the effects of different types of aids to learning science concepts from textual materials. The studies analyzed dealt with aids for selecting the important information contained in written materials and aids for building internal connections among the parts of printed materials. Studies pertaining to…

Sixteen concept words related to "matter" were described as simple textbook definitions and 16 multiple-choice items were constructed for each concept definition. These materials were used to compare the ability of 1,635 Tasmanian and 826 Indian students to recognize the concept definitions and their attendant verbal labels. (JN)

Approximately 500 nonscience major university chemistry students were surveyed to record their interpretations of specific chemical symbolism before presenting modern concepts of atomic and molecular structure, in an attempt to understand the thought processes entering students use as they interpret symbolism. Results are reported and discussed.…

The principles of cognitive psychology as they relate to rational number learning and instruction are discussed. Issues of knowledge acquisition, organization, retrieval and transfer are reviewed as they affect this area of the elementary school curriculum. Specific problems in learning about rational numbers and systematic student errors are…

Children's memory for stories was examined as a function of subjects' understanding of causal reasoning ability in stories. Results supported a developmental view in which recall performance was a complex interaction between characteristics of the learner and characteristics of the story. (Author/PCB)

Argues that Venn Diagrams are powerful probes of students' understanding of the meanings of terms and the relations between concepts. Examples of the various classroom contexts in which the diagrams can be used are provided. (JN)

Investigated the meaning that Hindi-speaking students (N=826) in India and English-speaking students (N=1,635) in Tasmania preferred when thinking about each of 16 key concept definitions associated with the theme "the nature of matter." Results show marked changes in the development of these preferences which raises issues for science…

What advanced 4- and 5-year-old children know about night and day in relationship to the earth and sun was studied to test the hypothesis that two teaching activities would help children to understand the cause of the phenomenon. Participants were 21 middle to upper class boys and girls enrolled in a part-time early childhood enrichment program…

Investigated (1) conceptions 40 African students used in solving floating/sinking problems; (2) nature of these conceptions; (3) kinds of arguments of epistemological commitment they displayed in their responses; and (4) if their conceptions differed from scientific conceptions. (JN)

Examines the development of metaphor by using structure-mapping theory to make distinctions among kinds of metaphors. Proposes that children can understand metaphors based on shared object attributes before those based on shared relational structure. Results indicate a developmental shift toward focus on relational structure in metaphor…
