Illustrates different types of opportunities for using computer assisted instruction (CAI) on personal computers in the teaching of economics with four examples of currently available software. Describes the difficulties in providing and supporting CAI, and concludes with an analysis of the difficulties caused by the "public goods character" of…

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)

Describes a variety of computer software. Subjects reviewed include history simulations and wordprocessing programs. Some of the eleven packages reviewed are Thog, North Utilities, HBJ Writer, Textra, Pro-cite, and Simulation Construction Kit. (BSR)

Learning about the physical environment from computer simulation models is discussed in terms of three stages: exploration, experimentation, and calibration. Discusses the effective use of models and presents two computer simulations written in BBC BASIC, STORFLO (for catchment hydrology) and SLOPEK (for hillslope evolution). (Author/GEA)

Reviews the uses of DEMOS, a set of demographic computer simulations which can be used to improve instruction in introductory sociology courses. Gives examples of both interactive and noninteractive exercises, concluding that DEMOS is easy to use and enjoyable, with approximately 90 percent of students recommending its continued use. (GEA)

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)

Presents various exercises and programs to demonstrate how low-resolution graphics (for Apple microcomputers) can be utilized in the mathematics classroom. (JN)

Presents the listing for a TRS-80 Model III program which illustrates the first law of robotics (all robots must be programed so that none of their actions will be harmful to man). Also discusses the rational for and development of the program. (JN)

Discusses Newton's method for approximating the roots of functions, indicating that students who program in BASIC can learn and appreciate the method by writing their own programs. Includes a hypothetical dialogue between teacher and student about the topic; sample program listings; and problems assigned to students who have written programs. (JN)

Discusses high resolution (hi-res) graphics programing on the Apple microcomputer, emphasizing its use in the mathematics classroom. Sample programs to plot dots and diagonals as well as programs for creating more complex visuals and patterns are included. (JN)

Describes an interactive simulation model which can be used to demonstrate population growth with discrete or overlapping populations and the effects of random, constant, or density-dependent mortality. The program listing (for Commodore PET 4032 microcomputer) is included. (Author/DH)

Offers suggestions for five computer-oriented classroom activities. They include uniting a writing class by having them collectively write a book using a word processor, examining FOR/NEXT loops, using a compound interest computer program, and developing a list of facts about computers. Includes four short programs which erase monitor screens. (JN)

Presents a program that provides a structured listing of BASIC computer programs in a text file. Indents for-next loops for better appearance and easier understanding. Lists program and provides for several versions of BASIC. (MVL)

The Bock and Aitkin Marginal Maximum Likelihood/EM (MML/EM) approach to item parameter estimation is an alternative to the classical joint maximum likelihood procedure of item response theory. This paper provides the essential mathematical details of a MML/EM solution and shows its use in obtaining consistent item parameter estimates. (TJH)
