Goodman's logit analysis (the simplest form of log-linear models) was used with hypothetical school survey data to analyze and predict teachers' attitudes toward proficiency tests. Logit analysis can estimate the "main effects" and "interaction effects" of categorical explanatory variables on dichotomous-dependent variables in…

This study examines the year-to-year movement in the wage differential between skilled and unskilled workers, 1907-72, using union contract rates in the construction industry. The author examines a number of hypotheses that have been suggested as explanation for changes in the skill differential. (Editor/HD)

The study sought to determine whether a teacher could efficiently and effectively develop, execute, and evaluate a mathematics program that would adequately enable pupils to learn. (Author)

Where estimation of abilities in the lower half of the ability distribution for the Raven Progressive Matrices is important, or an increase in accuracy of ability estimation is needed, the multiple category latent trait estimation provides a rational procedure for realizing gains in accuracy from the use of information in wrong responses.…

Ways are suggested in which economists and applied mathematicians construct and use models to study the economy. Several models are developed, each accompanied by a BASIC computer program to test its assumptions. (DT)

To examine how conceptual knowledge about fraction magnitudes changes as students' learning progresses, 5th and 7th-grade students were asked to solve fraction magnitude problems that entailed finding a fraction between two given fractions and then to evaluate solutions for similar problems that were modeled for them. When the given fractions…

In this study, the reliability of the American College Testing (ACT) Program's "Survey of Academic Advising" (SAA) was examined using both univariate and multivariate generalizability theory approaches. The primary purpose of the study was to compare the results of three generalizability theory models (a random univariate model, a mixed…

By including district variables at a third level, this study extended previous two-level hierarchical linear modeling (HLM) of multivariate relationships among Texas school-level characteristics and within-school mean Scholastic Assessment Test (SAT) scores and score differentiating factors (L. L. Hargrove, M. X. Mao, and G. Barkanic, 1996;…

Any interstate comparison that does not take differences in the cost of education into account will give an incorrect impression of the relative levels at which different states support their schools. The lack of cost-adjusted statistics on state expenditures for elementary and secondary education interferes with policy analysis, resource…

The University of Maryland offers a physics course as part of the Maryland Collaborative for Teachers' Preparation (MCTP) project. One of the course aims is to promote the learning of the concept of a function through the learning of physics. Students learn in small groups through problem solving and with the aid of microcomputer-based…

Maximum likelihood factor analysis provides an effective method for estimation of factor matrices and a useful test statistic in the likelihood ratio for rejection of overly simple factor models. A reliability coefficient is proposed for analysis of factor solution. (Author/RK)

Teacher organizations may be accepting larger classes in return for higher salaries. (Editor)

In presenting lessons in music theory by computer-assisted instruction, response-sensitive programing results in greater achievement than response-insensitive programing. (Author)

Article examines the problem of individualizing the instructional sequence so that the learning of a second-language vocabulary occurs at a maximum rate. (Author)
