An attempt is made to elaborate on the connections and differences between the objective and subjective elements of mathematical knowledge using case study analysis relative to how an epistemological perspective about probability and randomness impacts upon a short classroom teaching episode.

The relationships and possible effects of various personal home and school variables on the acquisition of functional biological, chemical, and physical scientific knowledge by tenth grade Israeli students (n=544) was investigated. Biology was the only subject in which functional knowledge was significantly related to nonformal science activities.…

Presents five activities to help students construct meaning for multiplying fractions through real-world problem contexts, physical or pictorial models, the recognition of patterns, and the use of calculators. In the context of a garden plot, worksheets examine various aspects of parts of plots, patterns in plots, and a maximization problem.…

Describes the use and rationale of "Silent Teaching," a teaching technique in which the teacher remains silent as students generate and evaluate hypotheses while trying to understand an as-yet undiscovered concept. (MDH)

A longitudinal study followed Brian from grade five through grade seven to examine his representation and development of mathematical knowledge. Some observations over the four years were that Brian liked to figure things out, responded poorly to suggestions not fitting the representation he constructed, and changed attitudes from purposeful and…

Evaluates the effectiveness of a course using a constructivist approach in reducing Dutch secondary school students (n=190) misconceptions about force. Concluded that the lessons were effective in changing students' ideas in regard to forces in rest situations and frictional forces and that learning effects were equally distributed over student…

The purposes of this study were to: (1) investigate the process of development of young children's ideas when (and if) they appropriate science from the conceptual area (i.e., light) during whole-class and small-group interactions; and (2) advance understanding of relationships between a collaboratively designed learning and teaching model and…

This study reports on an effort to improve the teaching and learning of physical science for prospective elementary teachers. As part of the effort, a new constructivist science curriculum model was introduced for field testing at a large midwestern university. The purpose of the study was to build a research base to guide future science teaching…

This paper reports research from four studies of how teachers come to learn professional knowledge based on theoretical frameworks of the developmental theories of Piaget (cognitive development), Kohlberg (moral development), Loevinger (ego development), and Hunt (conceptual development). Studies proceed on the assumption that a perspective of…

This summary of research in science education continues a long tradition of review and analysis of research in science education by the ERIC Clearinghouse for Science, Mathematics, and Environmental Education. The summaries provide an overview of recent research, provide research information in a succinct form for practitioners and development…

By the age of 4, children typically have separate schema for relating events in the physical world and for relating events to associated mental states. Generally, these schema cannot be coordinated until around 6 years of age, when the ability to use them together yields a structure for assigning intentionality. This intentional structure develops…

"Seeing Fractions" is an instructional unit for teachers in California that was trial tested in about 30 classrooms, grades 4 through 6 with diverse student populations, and designed to help students become aware of the variety of ways in which fractions are commonly used. The Introduction includes an overview of fractions and what…

The intent of this publication is to consolidate and critique research findings related to teaching and learning in the sciences as they were reported in 1990. The purposes of this and previous summaries include: (1) providing an overview of recent research activity for scholars in the field; (2) providing research information in succinct form for…

This study compared the acquisition of an initial place value skill when presented in a concrete, semiconcrete, abstract teaching sequence to acquisition of the same skill when presented at the abstract level only. The 24 subjects were elementary and middle school students (ages 8-13) with learning disabilities who were randomly assigned to…

A review of literature on the use of wordless picture books to develop language skills is presented as background for the relatively brief description of a project in which wordless picture books were used with Latino children. The project is a collaborative one between Bloomsburg University, Kutztown University, and Thomas Ford Elementary School…
