Statistical tables present information on characteristics of professional staff members in public elementary and secondary education in California. Included are certified personnel employed full or part time, and noncertified personnel serving in supervisory positions. The professional staff characteristics listed are racial or ethnic group,…

This report provides an analysis of microcomputer software available for elementary and secondary level instruction in 1989 as compared to 1984. Data from the Resources in Computer Education (RICE) database are used to compare distribution of software programs by grade level; hardware manufacturer; application type (drill, tutorial, simulation,…

The purpose of this study was to investigate whether parents were more likely to purchase home computers for sons than for daughters, and whether elementary and secondary students reflect sex differences in their attitudes toward computer use. The survey instrument was constructed to provide face validity in order to investigate whether computer…

Monte Carlo methods were employed to assess the relative power of the paired samples t test and Wilcoxon's signed-ranks test under ten population shapes. Results of the study indicated that: (1) each of the two statistics was more powerful than the other in given situations; (2) the power advantages of the t test under normal theory were small;…

The term "cluster analysis" refers to a set of statistical methods that classify entities with similar profiles of scores on a number of measured dimensions, in order to create empirically based typologies. A 1980 Minnesota House Research Report employed cluster analysis to categorize school districts according to their relative mixtures…

This statistical profile provides current demographic data for Washington State and its counties, incorporated cities and towns. Seventeen tables show population by age and sex; population for counties, incorporated cities and towns, and the state; components of population change; a rank order of total persons in incorporated cities and towns;…

In this study four research strategies used in previous studies of the socialization of cognitive skills were first contrasted and then assessed in terms of five criteria. (The data base for this study was 32 videotapes of mothers preparing their 7- or 9-year-old children to take a memory test.) The four strategies (frequency coding, fine-grained…

Three methods for estimating reliability are studied within the context of nonparametric item response theory. Two were proposed originally by Mokken and a third is developed in this paper. Using a Monte Carlo strategy, these three estimation methods are compared with four "classical" lower bounds to reliability. (Author/JAZ)

Student/Teacher Ratios are calculated by dividing the fall enrollment count by the number of full-time equivalent teachers. Full-time equivalency (FTE) is the amount of time required to perform an assignment stated as a proportion of a full-time position, and computed by dividing the amount of time employed by the time normally required for a…

This study investigated the use of media by distance learners enrolled in the NTI distance education programme. Two hundred and fifty five distance learners drawn from Oyo State, Nigeria, completed a questionnaire to determine the use of media, and factors militating against their effective use by distance learners. Research data were analyzed…

A statistical model is presented for processing quantitative admission data that weights equally two or more quantitative elements to ensure that the N most consistently high scorers qualify for the N available positions. The quantitative elements considered are overall grade point average (GPA), GPA in selected courses, and standardized test…

Explores the use of citation data in evaluating research performance of academic programs and individual faculty members based on a 10-year analysis of the School of Library and Information Science at Indiana University. The use of three methods conjointly for allocating citational credit to multiauthored works is discussed. (Contains 35…

Equal percentile (EP) and partial credit (PC) equatings for raw scores from performance-based assessments with free-response items are compared through the use of data from the Maryland School Performance Assessment Program. Results suggest that EP and PC methods do not give equivalent results when distributions are markedly skewed. (SLD)

Computer simulations were run to measure the relationship between testlet validity and factors of item pool size and testlet length for both adaptive and linearly constructed testlets. Making a testlet adaptive yields only modest increases in aggregate validity because of the peakedness of the typical proficiency distribution. (Author/SLD)

Studies sex bias portrayed in 25 picture books published during 5 decades between 1940 and 1980, particularly the use frequency and characterization of males and females. Frequency of depiction has become more evenly distributed, but girls are shown to be as passive dependent as found 50 years ago. (JB)
