Statistical tables associated with named probability distributions and their families, such as the standard normal, Student's t, and chi-square tables, among others, have been utilized for years and are still widely used today, especially for mathematics and statistics education. While such tables can be found in many statistics textbooks and even…

The evidence that teacher preparation programs have an impact on teacher quality is often limited. Progress in research on this topic will remain rather limited in its influence on practice until more proximal measures of teacher education outcomes can be established. The dearth of variables to measure the impact of teacher preparation programs on…

The fourth in a series of articles on the evaluation of microcomputer software for information storage and retrieval, conducted by the Netherlands Association of Users of Online Information Systems (VOGIN), presents test results for six indexing and full-text retrieval programs--Ask-It, KAware, Texplore, TextMaster, WordCruncher, and ZYindex. (13…

This second in a series of articles on a software evaluation project conducted by the Netherlands Association of Users of Online Information Systems (VOGIN) lists and compares specifications, properties, and test results for nine microcomputer-based software programs that fall into the category of classical information retrieval systems. (26…

This discussion of library software packages includes guidelines for library automation with microcomputers; criteria to aid in software selection; comparison of some features of available acquisitions, circulation and overdues software; references for software reviews; additional information on microsoftware; and a directory of producers and…

Lists and compares specifications, properties, and test results of eight microcomputer software programs for information storage and retrieval by endusers. This is one of a series of articles that have reported the results of a software evaluation project conducted by The Netherlands Association of Users of Online Information Systems (VOGIN). (22…

The procedures required to obtain the approximate posterior standard deviations of the parameters in the three commonly used item response models for dichotomous items are described and used to generate values for some common situations. The results were compared with those obtained from maximum likelihood estimation. It is shown that the use of…

Reports on tests evaluating nine microcomputer software packages designed for information storage and retrieval: BRS-Search, dtSearch, InfoBank, Micro-OPC, Q&A, STN-PFS, Strix, TINman, and ZYindex. Tables and narrative evaluations detail results related to security, hardware, user features, search capability, indexing, input, maintenance of files,…

Discusses results of a 1997 "CMC News" readers' survey of the top 10 CD-ROM titles used by schools. Compares results of previous surveys (1993 and 1995). Four tables and figures show number of users for each of the 10 CD-ROMs, top-10 rankings for year 1993, 1995, and 1997, increase in ownership of 7 of the 10 titles, and total respondents owning…

Comparison of three microcomputer statistical packages, SPSS, SAS, and BMDP, focuses on ease of use, ease of learning, documentation, accuracy, similarity to the mainframe version, and speed. The results of eight statistical multivariate analyses used to evaluate their performance are given. (LRW)

Presents the results of a comparative evaluation of four CD-ROM retrieval software packages using the Revised Richards-Brown CD-ROM Software Evaluation Model. CD Answer, SPIRS, KAware2, and ROMware are evaluated, and results indicate that SPIRS and CD Answer are the favored packages. (LRW)

Presents results of searching seven World Wide Web (WWW) databases with the same three questions and evaluates the performance of each database in answering the questions. Tables show search results and basic database information. Sidebars list WWW databases not studied and address the future of Web searching and fee-based WWW databases. (JMV)

Describes the development of computer-based searching methods to support literature-based discoveries in medical literature through a replication of the discovery of a connection between Raynaud's disease and dietary fish oil. Topics include the logic of literature-based discovery, information retrieval methods for text analysis, and statistics…

Describes an evaluation of educational software that compared software produced in Taiwan with software produced in the United States. Results showed a surprisingly small number of cultural differences other than language; article suggests that multimedia guidelines for international audiences would be helpful. (LRW)

Discusses the results of an ongoing research study to measure college students' microcomputer literacy before taking a microcomputer course. A brief review of the literature on computer literacy is provided, a comparative analysis of results is given, and a microcomputer literacy index is described that measures literacy and ranks students.…
