The derivation of the variance of similarity judgments is made from the 3-D process in nonlinear psychophysics. The idea of separability of dimensions in metric space theories of similarity is replaced by one parameter that represents the degree of a form of interdimensional cross-sampling. (SLD)

An experimental microteaching technique is discussed that uses a variety of components: modeling, lesson planning, teaching, and conferencing. Experiences with a group of trainees are reported. Evaluation checklists are included. (Contains 17 references.) (LB)

A strategy to encourage evaluation used by the Centers for Disease Control in the Division of Adolescent and School Health (DASH) is described. DASH personnel tried to make evaluation of human immunodeficiency virus education programs more attractive by providing materials and models for evaluation. (SLD)

This article presents a model for efficient assessment of young children with visual impairments or multiple handicaps. The approach has team members simultaneously observe various aspects of a child's functioning to gain an understanding of the child as a whole. (Author/DB)

Proposes that teaching methods be changed to move away from a positivist model toward an ecological model. Discusses three assumptions for future practice involving holism in environmental studies; the role of values in environmental studies; and the process of learning. (Contains 26 references.) (MDH)

Deals with an experiment in teaching elements of spherical geometry, contrasted with concepts of plane geometry, for students aged 10-15. Four sections list advantages of applying alternative models in education, describe the experiment, outline the theoretical background of alternative models, and offer conclusions about areas of application.…

The Atkinson-Shiffrin model of memory has three components: sensory, short term, and long term. Each memory process (such as encoding, storage, and retrieval) can be linked to specific teaching and learning strategies. (SK)

Discusses suggestions for the learning and teaching of mathematics based on a study examining the mathematics practices of carpet layers. Suggestions are made from the areas of (1) the school mathematics curriculum; (2) the methods used to teach school mathematics; and (3) research in mathematics education. (MDH)

Presents a lesson that introduces students to polarized light using a problem-solving approach. After illustrating the concept using a slinky and poster board with a vertical slot, students solve the problem of creating a polarized light show using Polya's problem-solving methods. (MDH)

Discusses the use of different medications for people with developmental disabilities and presents a paradigm for integrating behavior-analytic and psychopharmacological treatment interventions. The model is consistent with the least restrictive, yet effective, treatment philosophy and addresses assessment and treatment of medical issues,…

Presents the equations of motion governing the trajectory of a cricket ball subject to a linear drag force. Uses a perturbation expansion technique to solve the resulting trajectory equation for the range of a cricket ball struck into the outfield. (Author/ASK)

Describes the steps of the Pyramid Evaluation Model to evaluate programs and outcomes systematically and comprehensively through an impact model that examines goals, reviews program design, monitors program implementation, assesses outcomes and impact, and analyzes efficiency . (Author/JOW)

Presents two related theories for a new paradigm in teacher education. One uses the concepts of "episteme" and "phronesis" to introduce a new way of framing relevant knowledge. The other is a more holistic way of describing the relationship between teacher cognition and teacher behavior. (SLD)

Describes a model for schools searching for a project to provide focus for instruction across curriculum areas. Argues that schools can foster compassion in students and a desire to take action by selecting a theme that is both engaging and meaningful for students, and providing skills and knowledge from across the curriculum. (CCM)

Explains how a school developed a model for ensuring progression in experimental and investigative science. Provides progression steps and examples of models. (CCM)
