Suggests decision making techniques that can be used to estimate the consequences of choosing alternative courses of action, to select an optimum strategy, or to determine how sensitive predicted outcomes are to particular assumptions. Microcomputer use, quantitative techniques, and examples involving item reordering and adoption of word…

INSTAN, a computer program designed to aid in appropriate media selection for classroom teaching, comprises three interrelated sections which focus on instructional objectives, the instructional environment, and instructional material selection. INSTAN is not described as an all-inclusive media selection model, but as a paradigm for further…

Explores use of uniquely developed microcomputer programs at Purdue University Undergraduate Library which provide reference service when reference personnel are unavailable. These programs, which allow patrons to query specific subjects of interest, also generate statistical summaries used for development of library instruction programs,…

Highlights major happenings in educational computing in developed nations worldwide including Australia, Canada, France, Germany, Great Britain, Japan, Russia, and Sweden. The topics discussed include approach to computer education, each country's use of microcomputers in vocational schools, software development, and teacher education. (MBR)

The use of a microcomputer as the basis of a multichannel analyzer (MCA) system is described. Principles of microcomputer MCA, choice of microcomputer, input-output port, data display, MCA program, and interrupt routine (with flowchart) are the topic areas considered. (JN)

Equipped with simple sensors and software, a microcomputer can become a microcomputer-based laboratory (MBL). Discusses the value of MBL's and provides three programs which preview the new MBL kits available for science classes. A list of commercially available MBL's (with product names, current prices, and other information) is also included. (JN)

The use of trial-and-error strategies to solve problems is endorsed. Types of problems with which trial and error is effective are discussed, with examples of how it is used, and teaching considerations are briefly considered. A computer program for one problem is included. (MNS)

Three numerical coefficients for analyzing the validity and reliability of ratings are described. Each coefficient is computed as the ratio of an obtained to a maximum sum of differences in ratings. The coefficients are also applicable to the item analysis, agreement analysis, and cluster or factor analysis of rating-scale data. (Author/BW)

Presents detailed components of a six-hour inservice workshop to familiarize teachers with microcomputers. (MD)

Presents methodological considerations in developing an automatic cheap algorithm for computerized path diagraming, gives some plotted results, and describes a program which produces the plots from an input matrix of path coefficients on a standard line printer. The program accommodates unidirectional and reciprocal causation and represents…

Examines two language arts computer innovations that are based on the process view of reading and writing rather than on the "reductionist" or individual skills view. The first is a software program called "Puzzler," the second is the application of word processing in composition. (HTH)

Describes The Electric Poet, a computer program which uses color graphics to free the poet from mundane mechanics and allow new possibilities of form in writing verse. Its applications in working with hearing impaired and learning disabled students and use in studying works of the great poets are discussed. (MBR)

Explores current status of archival automation on both the national and local levels, and discusses its implications for control and access of historical documentation. Development of Selected Permutation Index by National Archives and Records Service, automation at Library of Congress (LC) Manuscript Division, and planning for automation are…

Describes the first library-sponsored Electronic Bulletin Board System (BBS), begun in November 1981 at North-Pulaski Branch of Chicago Public Library. Examples of logon routines, menu displays, recent features of the People's Message System, and censorship statements are included. BBS sources (noting address and price) and a nine-item…

The instructional computer program LOGO enables children to construct their own programs. This article presents an evaluation of LOGO and use of computers in education. The author discusses reasons why computer science belongs in high school rather than elementary school. (DF)
