Cites research findings to refute Piaget's contention of stages of cognitive development. Advocates continuous cognitive differentiation as a model. (CP)

Advocates the educational theories of David Ausubel as a basis on which to build science and mathematics curricula and instructional procedures. Offers interpretations of Piaget's conservation tasks in Ausubelian theory. (CP)

Develops the thesis that science education should be extended beyond the scope of scientific discipline to its applied aspects, namely, technology and its interphase with society. Suggests that curricula be developed which fosters scientific and technological literacy for all students. (JN)

Sixty-one Japanese kindergarten children were pretested on their concept of speed; approximately half of the children (experimental group) were then given a demonstration of visual speed, and the entire group was posttested. Concludes that the experimental group could acquire the concept of speed significantly better than the control group. (MLH)

Describes the development of six science teaching attitude scales, using the procedures similar to those of the Scientific Attitude Inventory. Included are field test results obtained from the elementary teachers of an inservice summer project. (CC)

Discusses insightful learning, trace system,'' and laws of perception and Pragnanz in connection with problem solving and critical thinking in science teaching. Suggests 19 guidelines for sequencing curriculum and identifying activities for use in science classes. (CC)

Describes the presence of high correlations between pooled scores on two test formats when administered to 170 students in an introductory physics course. Concludes the gradability of machine scorers is comparable to that of manual grading in this repeated-measures design. (CC)

Compared student performance on test of subject-matter after a 7 day unit on evolution taught by either individual study, group discussion, large-group instruction, or by a combination of these three methods. Found no significant difference among groups when pretest score used as dovariate. (AL)

Considers several components of the relationship between science, society, and science education. Discusses and draws conclusions regarding data gathered in these areas: public perceptions about science, science-related social problems, scientific methods and values, confidence in science, and support for science research. (CS)

Describes the use of interviews with children ranging in age from 6 to 13 to identify patterns of children's beliefs in the area of heat and temperature. Also discusses how this knowledge might be used in an instructional setting. (HM)

An ex post facto study of 1,486 education majors reported that 53.5% of participants were at the formal operational stage and 43.9% were at the transitional stage. Students with more science courses in grades 10-12 had significantly higher scores for cognitive development and science process skills. No significant differences were found in…

Investigates what two teachers learn from each other as they engage in the three-month coteaching of an engineering curriculum to Grades four and five. Provides direct and indirect evidence of teachers' knowledgability. Contains 34 references. (DDR)

Examines relationships between students' motivational and epistemological perspectives--or personal frameworks for science learning--and their cognitive engagement with peers during collaborative knowledge-building tasks. Contains 91 references. (DDR)

Examines student perceptions of gender-appropriate science courses through completion of the Course Selection Sheet (CSS) to select courses for themselves and members of the opposite sex. Contains 117 references. (DDR)

Describes a study that investigated whether scientific and nonscientific understandings in the same content area are linked. Finds that students' (n=107) explanations indicate that they were using an "if-then" type of reasoning which linked scientific and nonscientific conceptions. Contains 39 references. (Author/WRM)
