Interaction in the online learning environment has been regarded as one of the most critical elements that affect learning outcomes. This study examined what factors in learner-instructor interaction can predict the learner's outcomes in the online learning environment. Learners in K Online University participated by answering the survey, and data…

Objective: To evaluate relations among dietary habits, bone mineral density (BMD), visceral fat area (VFA), and arterial stiffness and recommend better dietary habits. Methods: One hundred and six men and 381 women (aged 18-84) received a health checkup and answered questionnaires, with subsequent measurements of BMD (speed of sound), VFA…

The main controversy as a result of the commercialisation of international education markets is that international students especially those from China are unable to perform as well as UK students in UK universities. So far, research has yet to identify the influence of placements on the academic performance of Chinese students from entry to…

Using logistic regression, this study sought to understand the relationship between district characteristics, district finances, levy characteristics, and campaign expenditures with new operating levy outcomes. We found that employee benefits as a percentage of the district's budget were negatively associated with levy outcomes, while salaries…

This paper explores the relationship between a peer-assessed reputation rating for each of the 247 doctoral universities and cross-institutional performance indicators for universities and their libraries. Using multiple regression, the variable of library expenditures, was the only consistently significant one using combinations of variables.…

Curriculum-based measurement of oral reading (CBM-R) is frequently used to set student goals and monitor student progress. This study examined the quality of growth estimates derived from CBM-R progress monitoring data. The authors used a linear mixed effects regression (LMER) model to simulate progress monitoring data for multiple levels of…

This paper aims to analyze the effects of certain characteristics of the educational systems on the social composition of schools. After accounting for significant effects of schools' social composition on student outcomes (this is confirmed on the basis of a multilevel analysis), we explore the impacts of distinct components of what we name…

This article examines the sociocognitive processes contributing to intention to use contraception and willingness to engage in unsafe sex, using extended versions of the theory of planned behavior (TPB) and the Prototype/Willingness model (Gibbons & Gerrard, 1995, 1997). Data were obtained from a questionnaire delivered to all the pupils in…

The testing of contemporary sociological theory often calls for the application of structural-equation models to data which are inherently collinear. It is shown that simple ridge regression, which is commonly used for controlling the instability of ordinary least squares regression estimates in ill-conditioned data sets, is not a legitimate…

A general class of regression models for ordered categorised data is developed and discussed. Thier properties are contrasted with log linear models and other methods of analysis. The general problem of fitting by maximum likelihood is discussed and solved. The models are shown to be multivariate extensions of generalised linear models and the…

The utility of several longitudinal data analysis models for use with educational attainment are discussed and illustrated on a large data set. Assumptions of the models, choice of scale units, and data transformations, as well as real-life implications are emphasized. (Author/JKS)

Analyzed the relative contributions of academic ability, music experience, and musical aptitude to predicting grades in college freshman music theory courses. Found that the best predictor of grades was the mathematics component of the Scholastic Aptitude Test (SAT). Data analysis revealed five factors that accounted for 78.6 percent of the…

In 1960, the New York City Public School System was decentralized into 32 school districts with limited authority over elementary and junior high schools. Locally elected district community school boards were provided for by State legislation. In this study factors relevant to predicting a candidate's success or failure in the 1975 and 1977 school…

The extent to which the Pharmacy College Admissions Test and other admissions criteria predict (1) academic performance during later years at Virginia Commonwealth University School of Pharmacy, and (2) scores on the National Association of Boards of Pharmacy Licensing Examination (NABPLEX), and a board of pharmacy law examination are assessed.…
