Trends for kindergarten through second-grade children were identified from data collected in a longitudinal study of how children develop science concepts. The study involved approximately 325 children from three school districts. A heuristic model of science learning was developed representing children's entering ability, home background, home…

Findings from two studies of fourth grade children learning the concept of mathematical equivalence are presented. The questions studied were: (1) Can knowledge conveyed in gesture but not in speech be tapped by a recognition technique; and (2) Does having implicit knowledge that is expressed in gesture but not in speech have implications for…

This research describes the evaluation of a science curriculum newsletter called BioRAP which serves as a vehicle to teach current health science content. The research objectives were to estimate the relationships of socioeconomic status, ethnic group, gender, grade, student ability, and classroom use characteristics with student knowledge and…

The goal of the Toledo, Ohio, Support Teacher Programs has been to improve the learning of math and science concepts at the junior high school level. This goal involves some basic changes in the way teachers interact with each other and with their students. The greatest changes have been in the movement away from the…

Mental retardation, learning disabilities, and intellectual giftedness have long been separated as different fields. In the past decade research findings suggested a continuity within the general intelligence spectrum which place the gifted on one extreme and the retarded on the other, as well as a two dimensional taxonomy of intellectual…

This paper addresses the role experiments can play in concept development. The study used a qualitative phenomenography research methodology. The interactions of one student with an instructor in a series of eight sessions on electric circuits is reported. The first three session focused on diagnosing the students' prior conceptions of electric…

Frame of reference theory (Marsh, 1990) proclaims that students make both internal ability comparisons across academic domains and external ability comparisons relative to peers in determining academic self-concept. The validation of this theory with academically able students seems crucial to their appropriate placement in specialized program…

Science and technology are often presented and taught as two separate essences. When this is done, students as well as teachers are forced to attempt to develop the appropriate linkages. This book is one of a series designed to help teachers develop their science and technological education in ways that are both satisfying to themselves and…

In recent years researchers have had a keen interest in scientific misconceptions and conceptual change. This paper describes approaches that can be used to provide a greater understanding of how students understand reality. The objective is to map belief space or terrain of belief regarding nature, i.e., to map the qualitatively different…

To determine if a significant relationship exists between the conceptual systems of principals and academic achievement, nine hypotheses were formulated stating that there is no statistically significant relationship between student achievement and the complexity of school environment, emphasis on academic achievement, professional training…

This research was designed to investigate several primary questions in comparing the Logo floor turtle to the Logo screen turtle: (1) Do young children gain different geometric concepts from experiences with the floor turtle than they do with the screen turtle? (2) Do young children learn to use the four basic Logo commands more efficiently with…

This study compares the concept of human nature in Germany, Java, and the United States. The study assumes cross-cultural similarities in the formal structure of the concept of human nature, while hypothesizing variation in content, for example, in the value systems. Four components of the concept of human nature were presented (personality…

This paper addresses two distinctive issues concerning animistic and anthropomorphic thought in the context of constructivist science education. The first concerns the extent of such ways of thinking, both within science itself and within school science. The second concerns the implications of this for theories of instruction in science education.…

Problems concerning conceptual change from existing knowledge (accumulated from everyday experiences or earlier teaching) to new scientific knowledge concerning natural phenomena are fundamentally the same for Western and non-Western students. However, difficulties experienced by non-Western students are magnified by factors such as their cultural…

An experiment examined whether children of different developmental stages expressed different levels of fear while viewing episodes of the television program, "The Incredible Hulk." Preoperational (3 to 5 years old) and concrete operational (9 to 11 years old) children were shown short videotaped segments taken from the program. Using…
