Modeled after the program "Mastermind," this program teaches students the art of protein sequencing. The program (written in Turbo Pascal for the IBM PC, requiring 128K, a graphics adapter, and an 8070 mathematics coprocessor) generates a polypeptide whose sequence and length can be user-defined (for practice) or computer-generated (for…

This paper investigates three methods for comparing medians rather than means in studying two independent treatment groups. The method that gave the best results is based on a normal approximation of the distribution of the sample median where the variance is estimated using results reported by Maritz and Jarrett.

Dicusses three education "anchors" weighing students down: adherence to print, overreliance on facts, and one-way transmission of information. Appropriate computer software can enliven a boring classroom by streamlining repetitive tasks (like revising and editing) and encouraging interactive construction of ideas. (MLH)

Presents a classification system of four microcomputer simulation types developed to evaluate their instructional processes: structured questions and graphics, variable-assignment exercises, diagnostic simulations, and group-interactive simulations. How this taxonomy contributes to three tasks associated with classroom use of software is…

Studies at the Curry School of Education (University of Virginia) have demonstrated that microcomputer-based simulations of classroom interactions increase participants' use of appropriate instructional techniques with computer-generated pupils. Performance feedback from the system resulted in significant decreases in inappropriate management…

How the microcomputer can be used to reinforce basic statistical concepts and techniques is presented. The methods for achieving this include specific statistical problems, projects, games, and simulations for use with microcomputers. (MNS)

Describes an Educational Products Information Exchange (EPIE) study which evaluated 163 elementary and secondary education microcomputer courseware programs for intent, content, methods and approach, and evaluation, to discover whether trends existed across areas and courseware types, and to determine strengths and weaknesses of available…

Describes graphical solutions of equations for stirred-tank reactors in series; data management software for producing and searching customized mass spectral libraries; least squares and chromatography programs; a low-cost data acquisition system for Apple microcomputers; nuclear magnetic resonance interpretation with graphics; chemical bonding…

Describes a computer-based instructional unit in cardiovascular physiology. The program (which employs simulated laboratory experimental techniques with a problem-solving format is designed to supplement an animal laboratory and to offer students an integrative approach to physiology through use of microcomputers. Also presents an overview of the…

An equating design in which two groups of examinees from slightly different populations are administered a different test form with a subset of common items is widely used. This paper presents standard errors and a simulation that verifies the equation for large samples for an equipercentile equating procedure for this design. (Author/BS)

Project SERAPHIM activities that are discussed include identifying, producing, and disseminating materials; reviewing computer-based instructional materials; distributing software; holding workshops on microcomputer use; holding symposia to determine direction microcomputer use is taking; and operating the SERAPHIM/-Chem Con Interface Project,…

Lists 12 science-oriented computer programs (indicating program name, source, RAM needed, compatible computers, and current cost). Also considers the use of these programs in educational and home settings. (JN)

Strategic differences in spatial tasks are explained in terms of different cognitive coordinate systems that subjects adopt such as standard versus arbitrary, task-defined axes. A theoretical account of mental rotation of individuals of low and high spatial ability solving problems from psychometric tests is instantiated as computer simulation…

Describes: Apple stereochemistry program; CNDO/2-INDO mini-computer calculations; direct linear plot procedure for enzyme kinetics calculations; construction of nonlinear Scatchard plots; simulation of mass spectral envelopes of polyisotopic elements; graphics with a dot-matrix printer; MINC computer in the physical chemistry laboratory; hallway…

Presents background information and the listing for a LOGO computer program which investigates an ancient mathematical riddle (related to the square root of seventeen). The simulation, written for Apple II microcomputers, can be easily adapted to other microcomputers. (JN)
