Reviews Piaget's stages of development and describes types of educational activities which are appropriate for specific levels of cognitive development. (CP)

The wealth of language and lore about frogs can be used to enrich learning in language arts, science, social studies, and the arts, as well as to investigate values and develop thinking skills. Activities are suggested and a list of appropriate books is provided. (MT)

Children in grades two and five explained such weather phenomena as wind, clouds, thunder, lightning, rain, snow, and rainbows during interviews. Results indicate that most students in both grades were at a stage of nonreligious finalism and do not use true causality in explanations. Implications for teaching are discussed. (DH)

Investigated whether instructing children in the component skills underlying Piagetian transitivity tasks would increase their performance on both transitivity-related tasks and on reasoning tasks not directly related to transitivity. Results indicate that incorporating the quantification of certain abstract symbols, training can influence…

This study focused on misconceptions related to light and vision. Researchers administered diagnostic tests about light, vision, and color before and after instruction to 227 fifth-grade students over a 2-year period. They also conducted 11 clinical interviews. The tests and interviews revealed that almost all students shared certain…

Describes an activity center where students work independently on problem-solving tasks. Participants keep records of their work and share ideas of activities with the class. Includes a list of tasks for the activity center. (MA)

This study explored questions about the effect of lesson structure and cognitive development on science achievement of 42 students in grades four and five in British Columbia. Increased lesson structure did not significantly increase achievement, and interaction effects were generally nonsignificant. Conservation ability significantly affected…

Reports findings of a study on children's perceptions and alternate conceptions about the human circulatory system. Summarizes the responses of fifth and eighth grade students on questions dealing with the heart and blood. Offers examples of hands-on activities and confrontation strategies that address common misconceptions on circulation. (ML)

The results of a study conducted with elementary school students in Tanzania are presented. A number of alternative conceptions were revealed. The role of sociocultural beliefs in forming these conceptions is described, and the implications of these findings for science teaching and teacher education are discussed. (Author/CW)

Presented are the instructions and suggested variations on a card game designed to help children learn to match shapes. A set of cards which may be photocopied for use are included. (CW)

Offers perspectives on how conceptual changes actually take place in students. Proposes that elements of Kuhn's concept of scientific paradigms and Wittgenstein's concept of the "language-game" be considered in an analysis of conceptual change. Explains how components of these models relate to science learning. (ML)

Presents criteria that science teachers can use to decide where a given classroom activity falls in a continuum from concrete to abstract. The system is intended as a way of selecting appropriate tasks for children based on their previous experiences and their level of development. (JM)

The fields of science education and science studies and their respective academic communities, while appearing to have many potential points of contact, remain surprisingly separate, with little apparent recognition of the relevance to the interests of each to work done within the other traditions. As a field of study science education deals with…

Investigated developmental and/or sex components of energy attitudes using Kuhn's Energy Opinionnaire. Results indicate that changes in student attitudes through grade levels are consistent with cognitive and affective development literature and that sex differences are more pronounced in older students (with females having a more external world…

Describes classroom activities to help children determine cause and relate the changes to the substances being changed. Advocates the use of "change jars" and making daily observations to teach the concepts that certain conditions promote change. Includes ideas using temperature, moisture, rotting, and sprouting to teach the concept of change. (CW)
