Instructions are given for building physical scale models of ordered structures of B-form DNA, protein [alpha]-helix, and parallel and antiparallel protein [beta]-pleated sheets made from colored computer printouts designed for transparency film sheets. Cut-outs from these sheets are easily assembled. Conventional color coding for atoms are used…

Describes a computer application that uses graphics, color, and animation to make the learning of statistical reasoning with uncertainty easier and more fun. Notes that the initial implementation focuses on the Dempster-Shafer model, although the design is a framework that can incorporate other models. Also discusses how the tool may be used to…

Describes five statistical simulation programs developed at Wichita State University--Coin Flip and Raindrop, which demonstrate the binomial, Poisson, and other related distributions; Optimal Search; QSIM; and RANDEV, a random deviate generation program. Advantages of microcomputers over mainframes and the educational uses of models are noted.…

"Bohr's Atomic Model" is a small interactive multimedia program that introduces the viewer to a simplified model of the atom. This interactive simulation lets students build an atom using an atomic construction set. The underlying design methodology for "Bohr's Atomic Model" is model-centered instruction, which means the central model of the…

A technique was developed to facilitate creating computer-based instruction (CBI) with a minimum of effort on the part of the author/coder, and the feasibility of using a structure which puts control of the lesson strategy into the hands of the student learner was investigated. A model which relieves the author of CBI strategy selection was…

Builds on a National Science Foundation (NSF) microcomputer based laboratory project to introduce system dynamics into the precollege setting. Focuses on providing students with powerful and investigatory theory building tools. Discusses developed hardware, software, and curriculum materials used to introduce model building and simulations into…

The Technology Edu-Camp described in this report was held in July of 1988 at Arkansas State Technical Institute. Purposes were: to provide vocational instructors an opportunity to expand their knowledge and understanding of the needs of technical occupations; to upgrade their technical skills; and to develop lesson materials for courses in…
