Reviews recent developments in quantitative and qualitative measures of information activities as they relate to sectoral studies (kinds of information, information institutions and services, messages, and communication technologies) and global studies (production and consumption of information, social change, information channels, policies, and…

Empirical Bayes methods are shown to provide a practical alternative to standard least squares methods in fitting high dimensional models to sparse data. An example concerning prediction bias in educational testing is presented as an illustration. (Author)

Data reported in this paper is part of a larger study which explored form five (14 to 16 year olds) students' ideas in probability and statistics. This paper presents and discusses the ways in which students made sense of task involving independence construct obtained from the individual interviews. The findings revealed that many of the students…

This study examined the predictive factors of persistence for African American students at historically black colleges and universities (HBCU) and at predominantly white institutions, and is based on John Bean's (1982) synthetic model, which incorporates background, organizational, environmental, attitudinal, and outcome variables. The hypotheses…

Examines the juvenile court system in the United States and traces its history and philosophy. Presents figures and statistics which pose questions involving the efficacy of the juvenile justice system. Presents some measures suggested by studies set up to establish uniform standards relating to treatment of the young. (Author)

Women's expectations of high rates of return to investment in higher education, particularly in nontraditional fields and in those requiring advanced degrees, are shown to be consistent with high levels of investment in these fields. Increasing workforce participation and decreasing fertility also contribute toward reducing the female-male…

Fall 1979 pharmacy school enrollments statistics are discussed. Enrollments reflect trends reported in previous years including: declines in total enrollments and the proportion of Black students in minority schools; little change in proportion of foreign students and students enrolled for the PharmD; and increases in females and underrepresented…

Studies show that wage differentials between men and women are widening, especially when race is considered, and women are still underrepresented in some fields. It is suggested that affirmative action for women, especially in professional occupations, might have far-reaching positive results in sexual equality and community leadership. (MSE)

The relative magnitudes of R-squared values computed through multiple regression models using grade equivalent scores, raw scores, standard scores, and percentiles as both predictor and criterion variables are compared. Grade equivalents and standard scores produced the highest R-squared values. (Author/JKS)

This article describes a meta-analysis of 75 comparative studies of an innovative method of college teaching, Keller's personalized system of instruction (PSI). The analysis establishes that PSI generally produces superior student achievement, less variation in achievement, and higher student ratings in college courses. (Author)

Simulated data typical of those from meta analyses are used to evaluate the reliability, Type I and Type II errors, bias, and standard error of the meta-analytic procedures of Schmidt and Hunter (1977). Concerns about power, reliability, and Type I errors are presented. (SLD)

One of the issues facing educational research workers today is the determination of the similarities and differences between countries and cultures in the factors that influence educational outcomes. The author of this article proposes a new approach to this problem. Usually when countries are compared, the complete student samples are taken into…

Introducing students to measurement concepts poses unique instructional challenges; yet, the importance of measurement issues for all data collection scenarios (e.g., the classroom, individual clients, sporting events) requires that students understand the value of basic measurement procedures. Illustrating the basic measurement topics of…

Statistics education is under review at all educational levels. Statistical concepts, as well as the use of statistical methods and techniques, can be taught in at least two contrasting ways. Specifically, (1) teaching can be theoretically and mathematically oriented, or (2) it can be less mathematically oriented being focused, instead, on…

School leaders are faced with the daunting task of anticipating the future and making conscious adaptations to their practices, in order to keep up and to be responsive to the environment. To succeed in a rapidly changing and increasingly complex world, it is vital that schools grow, develop, adapt and take charge of change so that they can…
