Presents an exercise to get students more intimately involved in the three dimensional nature of basic units by constructing models. Uses balsa wood, glue, sandpaper, and a square. Studies seven crystals: cubic, hexagonal, monoclinic, orthorhombic, rhombohedral, tetragonal, and triclinic. Plans are available for a Macintosh computer. (MVL)

Reports that young children in the pedestrian accident prone age range of four-eight years hold a variety of naive conceptions regarding speed. Proposes a primary science unit using a conceptual change approach. (MVL)

Proposes an approach to educational change that is nondisruptive to the present system, produces meaningful and lasting learning outcomes, and is cost-effective. Identifies the elements involved in creating this approach: learning and thinking models, technology integration, shared vision of the future, professional practice, interdisciplinary…

Three preservice teachers of students with severe disabilities were trained on systematic instruction skills, focusing on appropriate use of positive consequences and instructional prompts. Results indicated that immediate feedback was more effective with two student teachers and delayed feedback was more effective for the third. Teaching skills…

Conditions influencing conduct and impact of state-level program evaluation are explored. A model is offered as a guide for assessing conduct and impact, and its use is demonstrated by a case study contrasting the approaches of two states examining an issue raised by the Federal Health Care Financing Agency. (SLD)

Argues that the strategic differentiation between education and schooling is fundamental to the maintenance and development of an African-American cultural orientation and ideology. A conceptual model is presented to link schooling with perpetuation of existing relations of power and political culture in the United States. (SLD)

Action research, in which classroom teachers engage in systematic inquiry to develop new alternatives for approaching problematic classroom situations, is presented as a dimension of collaboration that has the potential to reduce teachers' resistance to changes in teaching practice as they work to accommodate diverse classroom populations.…

Describes an alternative method for identifying exemplary practices in early childhood education programs. In this approach, parents and practitioners identify exemplary practices after coming to know the practices and the context in which they operate through observation, interview, and document review. Discusses methodological issues raised by…

Describes the design and use of SCORE (Sales and Customer Service Occupational Readiness Education), courseware developed by AT&T to provide midliterate adult customer service representatives with computer-assisted instruction. Topics addressed include job simulations; skills in reading, writing, math, problem solving, and critical thinking;…

A framework is proposed for evaluating the learning ecology and processes created by information technology in schools and developing an ecological model for research. The evaluation of Project Comptown, an intervention with extensive use of computers in two Israeli communities (with over 6,000 students), illustrates the framework. (SLD)

Options are presented for accountability in Chapter 1 schools and identification of low-performing schools. Two options are suggested that could move Chapter 1 toward more local control or toward more national control. In either case, the shortcomings of using normal curve equivalent gains on standardized tests should be recognized. (SLD)

Presents an empirical model, previously used to examine characteristics associated with perceived quality in schools of library and information science, that may be utilized in future studies. Variables and their correlation with a discriminant analysis function are listed, and a histogram depicts score distribution. (four references) (EA)

Presents an activity that models the changes in the concentration of carbon dioxide gas in the atmosphere during the last 200 years as determined from glacial records. (PR)

Offers a model for choosing among CD-ROM, end user access, mediated online searching, or locally mounted files as alternatives for extending online catalogs and replacing printed indexes. Estimates of demand and comparisons of costs made at Trinity and Clemson Universities provide a quantitative framework for selection. (Contains four references.)…

Reviews concerns related to diagnoses in delivery of mental health services, specifically, application of the principles of the Diagnostic and Statistical Manual of Mental Health Disorders (DSM-III-R) to African-American children. An alternative diagnostic model is proposed, and recommendations are made for enhancing the diagnostic process. (SLD)
