Describes the design and development of a case-based reasoning (CBR) knowledge repository, including its case library and the search engine to support the technology integration community. The process and results of ormative evaluation following the concept of participatory design are reported to set the context for further research and…

Teachers can capitalize on young children's natural curiosity about the world around them by including science learning in the preschool curriculum. Science activities provide a rich knowledge base and foster skills in receptive and expressive language, skills in self-regulation, and skills in problem identification, analysis, and solution. (TJQ)

Outlines student involvement with a conservation project that aims to develop a Regionally Important Geological/Geomorphological Site network (RIGS) at a county level in the United Kingdom. Emphasis is placed on identifying, describing, evaluating, and documenting land forms of educational, research, historical, and/or aesthetic value. (MJP)

Provides examples of using real time data sources from the Internet and the World Wide Web to enable students to collect the data that leads scientists to scientific paradigms, expand the scope of instruction to regional and global perspectives, and integrate science with other curriculum areas. (DDR)

Describes two intuitive rules underlying students' conceptions in mathematics and science that are not always compatible with usually accepted scientific ideas. The intuitive rules are: "More of A, more of B" and "Subdivision processes can always be repeated." In teacher education, it is important to raise instructors'…

Describes several exploratory sites where peacemaking is becoming an integral part of teacher education and reeducation within a university, research site, and student teaching practicum. The paper introduces a peacemaking school, highlighting shared learning of an experienced and a student teacher who wrote, read, talked, listened, and problem…

Described is a student-produced bulletin board that illustrates that mathematics is a universal language and that mathematics is being created around the world. Presented are two approaches for resolving a problem involving three equations and three unknowns. (KR)

Outlines an issue-centered approach to teaching aesthetics, where students identify and analyze possible solutions before learning an aesthetician's viewpoint. Suggests that teachers acquire basic aesthetic knowledge but also be willing to accept planned uncertainty as an educational principle. Presents a fictional art forgery scenario to…

Twenty learning-handicapped and 20 nonhandicapped intermediate-grade children worked on a mathematics problem-solving task on a microcomputer. Their social and instructional interactions were compared as group configuration (individual, homogeneous dyad, and heterogeneous dyad) and task difficulty changed. The computer's effect on the conversation…

Presents a two-day lesson from the Alberta (Canada) Education Curriculum for upper elementary or middle school students designed to explore ethical decisions when confronted with value conflicts. Outlines goals, materials, and procedures. Indicates instructional objectives are analysis of conflicts in terms of moral and ethical values; and…

Describes a study that examined the effect of computer programing experience on the mathematical problem solving achievement of high school students. The variables studied are discussed, including gender, ability, socioeconomic status, prior math experience, and access to a home computer, and a path analysis model is explained. (34 references)…

Discusses cooperative problem solving among Open University physics and math students and describes three studies that investigated how to design effective computer-based support for collaborative learning in distance education. The value of peer interaction for learning and problem solving is discussed, and students' attitudes to group work are…

Describes the development and evaluation of an interactive videodisc designed for Open University students in a physics course that explores the physical properties of water. The user interface is discussed; software is described; videodisc production is explained; and results of an evaluation of student attitudes from questionnaire responses is…

Describes responses of fifth to eighth grade students to different types of test items requiring estimation. Reports that performance differed by item format, types of numbers and operations in the items, and grade level of students. (Author/YP)

Described is a year-long study of the way a group of six 12-year-old children went about solving a special class of geometric problems using a computer and a limited set of LOGO programing tools. Examines solution strategies deciding whether those strategies led to insights about mathematical relations. (Author/MVL)
