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)

Describes a writing program that addresses adult students' limited access to computers and the program's effect on a pilot group of students. Offers some preliminary conclusions about the effects of computer availability on teaching methodology. (MS)

Solves the problem of the reproduction of rabbit pairs utilizing the Fibonacci sequence. Examines modified versions of the problem, and presents a vignette of one modification based on the author's experience in using the approach with preservice middle school teachers. Extends the approach to other related problems. (MDH)

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…

Discusses the use of computer visualization to motivate and support mathematical dialogues. Describes the "Scientific Visualization Software Suite," a set of public domain visualization tools from the National Center for Supercomputing Applications. (Author/MDH)

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…

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.…

The Socratic method of teaching, which uses open-ended questions asked in a logical sequence, is discussed. Suggestions for structuring curriculum content around seven adult learning principles and Socratic process analysis systems for student motivation are included. (SLW)

Described is the use of story telling as a context to introduce mathematical concepts by providing a model, offering problem-posing situations, stimulating investigation, and illustrating concepts. Examples of appropriate stories are given for the primary and low secondary levels. (MDH)

A method was developed using a deck of cards to teach Japanese fifth graders to calculate the area of a parallelogram. Investigations with 59 male and 45 female students demonstrate the superiority of the method to that previously used in terms of recall at one week. (SLD)

Describes an activity that demonstrates a teaching-learning model in which students ask yes or no questions to determine an unknown number on a number line. Provides a sequence of five steps to carry out the activity and suggestions for extending and expanding the activity for different grade levels. (MDH)

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)

This study formulated and tested a mathematical model to predict learning in which the amount of correct information recalled from an audio learning task is a function of the rate of oral communication. (Contains 36 references.) (MDH)

Describes a simulation exercise developed for an introductory biology course for nonmajors. The simulation focuses on the control of western spruce budworms in forests of the western United States. A nonlinear, multivariate simulation model is used. (PR)
