Since computer programs have been available for estimating and testing linear causal models, these models have been used increasingly in the behavioral sciences. This paper discusses the problem that very different causal structures may fit the same set of data equally well. (Author/LMO)

Presents questions to consider when selecting a computer gradebook program. Questions cover (1) attendance, (2) academic progress, (3) reports, (4) design features, and (5) customer support. (CH)

This annual article reviews the progress and pitfalls experienced by the automated library system marketplace during 1985. Marketplace activity is represented by events in four segments: turnkey systems; library-developed software; software designed to run exclusively on microcomputers; and production of computer output microform catalogs. List of…

Association for Educational Communications and Technology (AECT) officials who travelled to People's Republic of China present a first-hand view of China's interest in and use of educational technology. Discussion includes China's educational environment, nationwide education goals, microcomputer and computer software suppliers and educational…

The problem of controlling the grizzly bear population at Yellowstone is described. The results are presented in graphical form and discussed. A computer program is included. (MNS)

Discusses number and type of microcomputer software programs useful to libraries and types of hardware on which they run, as identified by Nolan Information Management Services. Highlights include general application programs, applications designed to support library technical processes, producers of library software, and choosing among options.…

Describes how microcomputers, together with an in-house developed expert system, are assisting Sweden's Linkoping University library staff, who possess beginning programing skills and computer expertise, in improving library performance. An example illustrating how the dimensional flowcharting improved the interlibrary loan operation is presented.…

Presents complete listing and documentation for an Applesoft program which stores test grades for every student, handles 10 different classes, calculates cumulative grade points and percentage grades, grades, drops lowest test grades, generates hard-copy reports, adjusts test scores for a class, and calculates test mean and standard deviation. (JN)

Presented are instructions for activities in which a calculator is used to investigate algebraic concepts. Also presented are short computer programs involving topics taught in prealgebra and an activity in which a trapezoid is transformed into a circle. (JN)

Methods to make computer searching as simple and efficient as possible have led to the development of various data structures. Data structures specify the items involved in searching and what can be done to them. The nature and advantages of using "self-adjusting" data structures (self-adjusting binary search trees) are discussed. (JN)

Discusses modifications in the fatty acid monolayer experiment to reduce the inaccurate moleculary data students usually obtain. Copies of the experimental procedure used and a Pascal computer program to work up the data are available from the authors. (JN)

Computers may help students delve farther into social studies research topics. The role of the computer in database management is explored in this article. (DF)

Demonstrating petroleum engineering concepts in undergraduate laboratories often requires expensive and time-consuming experiments. To eliminate these problems, a graphical simulation technique was developed for junior-level laboratories which illustrate vapor-liquid equilibrium and the use of mathematical modeling. A description of this…

Describes five categories of computer programs useful for content area reading instruction: utility programs, word processing, simulations, telecommunications for access to a database, and story architecture. (HOD)
