Discusses various types of transducers and explains the use of a photoresistor in sensing light. Describes various hardware and software combinations which can be used with photoresistors in science laboratory experiments. Presents general applications of this instrument in light-meter, solarimeter, and colorimeter experiments. (TW)

These FORTRAN programs and MATHEMATICA routines were developed in the course of a research project titled "Achievement and Assessment in School Science: Modeling and Mapping Ability and Performance." Their use is described in other publications from that project, including "Latent Traits or Latent States? The Role of Discrete Models…

A high-breakdown estimator is a robust statistic that can withstand a large amount of contaminated data. In linear regression, high-breakdown estimators can detect outliers and distinguish between good and bad leverage points. This paper summarizes the case for high-breakdown regression and emphasizes the least quartile difference estimator (LQD)…

This manual is intended as a guide and source of ideas for using single switches in adaptive software programming for people with disabilities who cannot use a traditional keyboard. The manual and associated program disk are comprised of over 100 programs, routines and files illustrating various uses of single switch and adaptive input devices.…

This reinforcement activity has been used by students from the elementary school level to the graduate school level who possess intermediate level ability in programming Logo. The activity, which consists of writing Logo programs that animate an object, can have several positive effects as it: (1) helps develop problem-solving skills; (2)…

This document contains the listings for 46 computer programs which are designed to teach various concepts in chemistry and physics. Significant time was spent in writing programs in which students would input chemical and physical data from their laboratory experiments. No significant time was spent writing drill and practice programs other than…

Discusses how computer-generated music can be used as a starting point to explore the science of sound. Listings for programs which focus on pitch (including a pitch matching game), beat, and frequency are included. (JN)

Describes how the International Futures Global Model (IFS) was developed for education and theory building. States that the model represents global demographic, agricultural, energy, and economic systems. Describes the two existing versions: a smaller one developed specifically for microcomputers and a larger one initially developed for mainframe…

Provides several algorithms that use extended precision methods to compute large factorials exactly. The programs are written in BASIC and PASCAL. The approach used for computing N considers how large N is, how the built-in limitation on exact integer representation can be bypassed, and how long it takes to compute N. (JN)

Presents an example of mathematics from an algorithmic point of view, with emphasis on the design and verification of this algorithm. The program involves finding roots for algebraic equations using the half-interval search algorithm. The program listing is included. (JN)

The original nine programs for semantic differential analysis have been condensed into three programs which have been further refined and augmented. They yield: (1) means, standard deviations, and standard errors for each subscale on each concept; (2) Evaluation, Potency, and Activity (EPA) means, standard deviations, and standard errors; (3)…

A microcomputer controlled interactive videotape program is described as one way to supply special education teachers with inservice and/or consultation services. The approach allows inservice teachers to strengthen classroom teaching skills outside of the classroom. Programing directions are offered written in the SuperPILOT Authoring Language on…

Reviews fourteen econometric and forecasting programs for the IBM PC family of computers. The comparison is based on analytical capabilities, cost, operating characteristics, and user-friendliness. Concludes that the programs do not differ enough to provide grounds for rejection of one program in favor of another. Includes names and addresses for…

Four articles discuss library uses of dBase III: (1) an interlibrary loan journal request file; (2) an acquisitions system; (3) customized multi-column output for reports; and (4) a circulation system. Program listings are included. (EM)

This article examines 16 selected examples of microcomputer software and videotape programs which may be used to achieve the goals of law-related education. (JDH)
