Describes an expert system designed to simplify evaluation of teacher-authored high school matriculation examination forms for official recognition. Because conventional knowledge-engineering methods were inadequate, a learning-by-example model called the Ordinal Learning Model was utilized. Responses from the system's users during a two-year beta…

Describes two QuickBASIC programs that provide students direct experience with interpreting correlation scatter-plots. Maintains that the programs can be used in classroom exercises to highlight factors that influence the size of a Pearson correlation coefficient. (CFR)

Describes a QuickBASIC program for demonstrating the differences between main effects and interactions in factorial designs. The program can be used in conjunction with a traditional lecture to improve student understanding and develop skills in recognizing main effects and interactions from graphic displays. (CFR)

Presents five charts and graphs drawn from the latest "Bowker Annual" that show the average cost of books, periodicals, textbooks, videocassettes, and cassette tapes for elementary and secondary school libraries from 1979-89. (LRW)

Alternate reasons for conducting program evaluation in community health care (CHC) settings and their relationships with information needs were explored in a survey of 136 CHC decision makers. Major reasons for conducting program evaluation included accreditation, true evaluation, and pseudoevaluation. Information needs were predictors of true…

Examines the adaptation of a set of library performance measures derived from a UNESCO manual to Swedish libraries. The basic principles of the measurement process and general library objectives are identified, and the difficulties encountered during the study are explained. The Swedish results are compared to the ideal measures presented in the…

Examines the effects of writing assignments on more than 250 undergraduate students' attitudes and on their classroom performance. The experimental writing group perceived both the subject matter and the course requirements more favorably, and also scored somewhat higher on average for the final examination, though not significantly higher than…

Describes the application of expert systems to provide computer-assisted instruction support to students to facilitate their learning of both fundamental and advanced statistical concepts. Provides examples of both a modular system and an integrated system which utilize VP-Expert, an expert system development shell. (14 references) (Author)

Reports on the Public Library Association's data collection project for 1987-91. Statistics show most libraries are progressing in terms of financial support and use, although not dramatically. Data on the role selection process and output measures are included. (Contains seven references.) (EAM)

The Level-11 vocabulary subtest of the Iowa Tests of Basic Skills was analyzed using a two-stage latent trait approach and data set of 2,356 examinees, approximately 11 years of age. It is concluded that the nonparametric approach leads to efficient estimation of the latent trait. (SLD)

Examines economic-attainment patterns of foreign-born male workers in the U.S. in 1980 to determine the influence of individual-level factors such as educational attainment, labor market experience, etc. Results indicate that, although microlevel characteristics are not complete answers, they are important for most foreign-born populations in…

Describes the use of a student-designed questionnaire to generate data for teaching statistical procedures and concepts. Maintains that students learn firsthand that data analysis is an integral part of the research process. Concludes that students find real data more interesting. (CFR)

The influence of positive achievement motivation was tested by analyzing data for 594 Norwegian sixth graders and 21 previously published studies, with simultaneous categorization of subjects on positive achievement motivation and test anxiety/fear of failure. Analysis of variance and multiple regression analysis indicate that positive achievement…

D. Freedman and others and W. Clark and P. Morrison misunderstand case law in the voting rights area and have unrealistic standards of precision that, if adopted, would make it virtually impossible for minority plaintiffs to succeed. Ecological regression, when used with care, is a reliable tool. (SLD)

Identifies current challenges to children's library services including inequality in access to information; integration of information skills in the classroom; rising costs, low budgets, and increasing demands; the state of book collections; and the need for research at state and national levels. Local examples of successful solutions are…
