Data from the National Research Council's Doctorate Records File extract prepared for UCLA indicated that source of support was the most important variable in predicting time to doctorate. Following source of support were postdoctoral plans, number of dependents, sex, and field of study. (Author/MLW)

This bibliometric investigation of literature on microcomputers in library and information services focuses on the years 1973-1986. Five printed reference tools and three online databases were searched to examine the number of publications, types of documents, contributing languages and countries, and the productivity of individual authors.…

Using St. Bonaventure's program as an example, claims that undergraduate journalism students can benefit from studying research theory and methodology and then applying it in their senior year. Indicates that these programs help overcome faculty inertia over quantitative analysis and that surveys and content analyses represent the most popular…

Using data from the High School and Beyond, this article presents statistical procedures to estimate the effect of dropping out of high school on cognitive achievement test scores. Each sampled dropout is matched to a student remaining in the same school. Methods for addressing the possible omission of covariates are described. (BS)

Between 1980 and 1984 SAT scores rose 8 points for whites and 15 points for non-whites, but the overall mean increased only 7 points. This article explains that this is not an arithmetic error, but an example of a statistical phenomenon called Simpson's Paradox. It describes how to avoid it. (JAZ)

The results of this issue's series of articles are summarized, and implications for theory, research, and practice are discussed. Initial academic achievement was the strongest predictor of student achievement. The impact of attentiveness, motivation, student background, sex, and time on task were also described. (GDC)

Hint, pegword experience, and hint plus pegword experience conditions were evaluated against three other conditions: (1) a no strategy control condition; (2) an instructional treatment to maximize elaborative strategy use; and (3) an instructional treatment to minimize elaborative strategy use. Results clarify the nature of elaborative production…

This paper presents two related studies describing the development and validation of the Teacher-Child Rating Scale (T-CRS), a brief objective socioemotional measure. Teachers rated K-6th graders on the T-CRS, and ratings were factor analyzed into three six-item problem and three six-item competence scales. (Author/LMO)

Using alternative models, wage and job competition predict different outcomes for an exogenous increase in supplies of educated labor. Regression studies based on the models account for very little variability in wages of new labor market entrants in 1966-1976. (Author/MSE)

Results suggest that while homework assignments, tests, and required texts increase the time students allot to a given course, and time allocated to a given course has a positive effect on course grades, the combination has a negative effect on course grade. High school performance is positively related to time given to a course but not to course…

ifferent evaluation models were applied to data from a high school career education program to investigate problems in statistical conclusion validity and program effectiveness judgments. If potential threats to internal validity are analyzed and protection strategies are developed, more confidence in unplanned ex post facto design using a…

The interrelationships of a variety of student aptitude and achievement measures are examined in a sample of 88 Australian undergraduate students, and the critial role of the data analyst in examining the relationships is discussed. (MSE)

This study of training needs utilized a questionnaire to assess participant's opinions of knowledge level that should exist and knowledge level that does exist in 25 content areas and analyzed the resultant data using three different approaches: mean difference analysis, multicomponent data analysis, and weighted need index. (MBR)

The purpose of this study was to determise the relative loss in statistical power of traditional methods of analysis when response-shift bias is present. Five methods of analysis (posttest scores only; postminus pretests; postminus retrospective pretest; postcovaried by pretest; postcovaried by retrospective pretest) were compared. (Author/BW)

The effectiveness of computer-assisted instruction to conduct pharmacy therapeutics case analysis exercises was compared with the traditional conference format. Pre- and posttest scores were compared statistically within and between groups to determine knowledge gained and comparative effectivness of teaching. (Author/MLW)
