This study examines thought, language, and related action in sixth-graders working to understand concepts related to mass, volume, and density. Students from a heterogeneous urban classroom worked in various social contexts including individually, in pairs, in groups of four, and as a class. Their work was examined via videotapes, field notes,…

The Philadelphia Collaborative for Excellence in Teaching Education (CETP) helps develop, implement, and evaluate a new model for science and mathematics K-12 teacher preparation. It involves collaboration of two colleges and a school district. One of the collaborative's main objectives is to redesign the content and pedagogy of core mathematics…

The Plant Information Center (PIC) is a project funded under the Institute of Museum and Library Studies that aims to provide global access to both primary and secondary botanical resources via the World Wide Web. Central to the project is the development and employment of a series of applications that facilitate resource discovery, interactive…

In order to identify the IS (Information Systems) skills in greatest demand in Connecticut and the New England region, classified ads for business-oriented IS positions appearing in the region's major newspapers during the summer of 1998 were analyzed. This paper highlights these findings and compares them to the skills employers from other…

This study examines the underlying structure of the teacher language arts and science questionnaires from a project studying the impact of the Maryland School Performance Assessment Program (MSPAP). The dimensions of the questionnaire concerning practices and attitudes related to the MSPAP were studied, as well as the extent to which the on-grade…

This paper present a case study on how the teaching methods in a number of modules in the Department of Information Science at the University of Pretoria (South Africa) have been transformed from traditional classroom presentations to a learner-centered approach supported by material on the World Wide Web and by e-mail and listserv interaction.…

A central premise of the discovery-learning and progressive education movements was that the child's own questions are the most appropriate starting point for instruction. Recent advances present new opportunities for discovery-oriented learning. This project has been attempting to create a classroom environment which affords students the…

For each of two years, 50 Hispanic and Black eighth graders were selected for a field-based, environmental science summer program designed to nurture math and science talent and encourage bright, minority youth to persist in school. Students were selected on the basis of participation in an outreach program, essays, grades, recommendations, and an…

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 used naturalistic inquiry methods to examine reasons why some members of minority groups, despite discouraging odds, persist in the sciences or science related disciplines. Interviews were conducted with 10 African American upperclassmen majoring in natural science or science related disciplines at a predominately white coeducational…

This study is second in a series demonstrating that achievement tests are multidimensional and that using psychologically meaningful subscores in national educational surveys can enhance test validity and usefulness. National Education Longitudinal Study 1988 (NELS:88) 8th- and 10th-grade science tests were subjected to full information item…

This paper reports the results of a 2-year longitudinal study of the development of primary teachers' understanding of science concepts (specifically, "force" and "energy") following inservice education, and the extent to which movement towards the scientific view was achieved and maintained. The approach to inservice education…

Educational computing based on the primacy of human agency is explored, considering ways in which power can be apportioned and exercised in order to enhance educational computing. Ideas about power and control are situated epistemologically. A first consideration is educating for human control of computer technology. Research suggests that…

Policy and practices in the use of computers in education in Greece and in education for computer use are reviewed. Given the centrally controlled and funded educational system in Greece, major decisions that involve major funding must be considered at the highest levels of decision-making. Computers began to be introduced in Greek schools at the…

This paper discusses the ongoing prototype of the Software Collaboration Model designed to meet the needs of both public and higher education. The model is based on instructional design principles and proposes that both public and higher education institutions can benefit through the collaboration of senior software design students and inservice…
