This article investigates two common methods of determining the line of best fit and then expands on the techniques used in these methods to find the line of best fit by graphing, estimating and using a microcomputer. (PK)

Provides mathematical activities in reproducible format for students in grades seven through ten. Intended to review and reinforce mathematical symbolism, concepts and relationships appropriate for middle school students. The game format is modeled after a television game show. (PK)

The hypothesis is examined that, in British Columbia, when variables measuring socioeconomic status, district resources, and basic district characteristics are controlled, no significant differences between aggregated student achievement will remain. Results suggest that districts are significant sources of achievement variation and that…

Discusses design and validation of a teacher-managed model employing programed-type learning materials for teaching college-level statistics which matches context of lessons to student background and interests. Current work in developing and field-testing a computer-assisted model of this type for teaching arithmetic concepts to elementary school…

Reports on the amounts and trends in spending on research and development in chemistry in the United States. Profiles industrial, federal, and academic sectors, both in applied and basic research. (JM)

Explores the great diversity of public and private support of education in various countries. Part I presents a theoretical model relating the relative size of the educational private sector to excess and heterogeneous demand. Part II applies this model to the United States, Japan, Holland, and India. Includes 18 references. (MLH)

In an experiment manipulating artificial data in a factorial design, model misspecification and varying levels of error in measurement and in model structure are shown to have significant effects on LISREL parameter estimates in a modified peer influence model. (Author/LMO)

Circulation time-series data from 50 midwest academic libraries were used to test 110 variants of 8 smoothing forecasting methods. Data and methodologies and illustrations of two recommended methods--the single exponential smoothing method and Brown's one-parameter linear exponential smoothing method--are given. Eight references are cited. (EJS)

Stepwise discriminant analysis coupled with logit regression analysis of freshmen data from Brandon University (Manitoba) indicated that six tested variables drawn from research on university dropouts were useful in predicting attrition: student status, residence, financial sources, distance from home town, goal fulfillment, and satisfaction with…

Compares classical multiple regression with Bayesian m-group regression, including cross-validation of both methods, in a study to predict first-quarter grade point average in various curricula for community colleges students who had completed developmental studies programs. Finds informal counselor prediction the largest contribution to…

Applies an economic model of occupational supply to librarianship to develop models that explain determination of number of accredited M.L.S. graduates and their starting salaries. Models are used to project graduates and salaries through 1990, then extended to project additions to supply of librarians from all sources. (36 references) (EJS)

A solution to the problem of specification error due to excluded variables in statistical models of treatment effects in nonrandomized (nonequivalent) control group designs is presented. It involves longitudinal observation with at least two pretests. A maximum likelihood estimation program such as LISREL may provide reasonable estimates of…

Secondary school teachers in southern Illinois were surveyed about their schools' course offerings in law-related education, their use of prepared project materials for those courses, and teacher preparation. Southern Illinois schools offered these courses in similar proportions to schools throughout the state. Teachers requested more education…

Recent federal legislation has dealt directly with medical school class size. This study examines the relationship between increases in entering class size in American medical schools and changes in a variety of educational variables. (LBH)

In recent years, there are more and more Chinese students going abroad for studying, and within them, the most students decided to study in the United States. But although in general the academic resource and quality of American universities is better than Chinese, the cost of studying abroad is much higher than studying in domestic colleges.…
