Points out that 108 studies in the first 25 volumes of AV Communication Review used univariate analysis of variance to test experimental hypotheses, and suggests that researchers include omega-squared values in their reports to permit estimation of the relationship between x and y variables, and correlation data for comparing studies.

Three nonparametric alternatives to the parametric Bartlett test are presented for handling the K-sample equality of variance problem. The two-sample Siegel-Tukey test, Mood test, and Klotz test are extended to the multisample situation by Puri's methods. These K-sample scale tests are illustrated and compared. (Author/GDC)

A study was conducted to investigate the teaching methods valued and used by faculty in Arkansas public higher education institutions at the freshman and sophomore levels. The participants were 336 teachers who responded to a 21 item survey distributed to college teachers in Arkansas. The study sought to collect relevant demographic data and to…

This comparative study was designed to investigate how online and traditional face-to-face (FtF) students used different learning styles in a graduate educational course. A nonequivalent control group design was employed. The study involved 19 students in an experimental group (online section) and 25 students in a control group (FtF section) in a…

The purpose of this study was to examine students' levels of engagement in educational practices by enrollment status, time of enrollment, and size of college in community colleges. Specifically, this study assessed the quality of the undergraduate education through students' self-reported data about their academic and nonacademic activities. The…

Statistical significance is often inappropriately equated with evaluating result importance and evaluating result replicability, even though these are three somewhat different issues. The prudent researcher must separately assess each of these elements of the "research triumvirate" by using different methods. This paper focuses on two…

A general model is described which can be used to represent the four common types of meta-analysis: (1) estimation of effect size by combining study outcomes; (2) estimation of effect size by contrasting study outcomes; (3) estimation of statistical significance by combining study outcomes; and (4) estimation of statistical significance by…

This study compared three approaches to the two-factor experiment with repeated measures on one factor: (1) the conventional mixed model analysis of variance, (2) the Greenhouse-Geisser conservative analysis of variance, and (3) multivariate extensions of analysis of variance. Computer simulated data were used in a total of 96 sets of covariance…

THIS INVESTIGATION WAS DESIGNED TO PROVIDE DATA ABOUT THE CHARACTERISTICS OF SOCIAL-POLITICAL ACTION LEADERS AT ONE UNIVERSITY AND TO COMPARE THOSE CHARACTERISTICS WITH OTHER TYPES OR CATEGORIES OF STUDENT LEADERS. NINE RESEARCH HYPOTHESES IN NULL FORM WERE FORMULATED TO FACILITATE STATISTICAL TREATMENT OF THE DATA. FROM A TOTAL OF 559 ELECTED…

Five distribution-free alternatives to parametric analysis of covariance are presented and demonstrated: Quade's distribution-free test, Puri and Sen's solution, McSweeney and Porter's rank transformation, Burnett and Barr's rank difference scores, and Shirley's general linear model solution. The results of simulation studies regarding Type I…

This report compares findings from application data the End of Training surveys administered to Master Teachers (MTs) participating in the Classic version of Intel Teach to the Future and those who took part in the Expansion version of Intel Teach to the Future. Classic survey data were collected between March 2001 and July 2002. Expansion survey…

The ideal item in the criterion-referenced testing situation is the item with a nonsignificant discrimination index and a high difficulty level; items that discriminate negatively are clearly unacceptable; and items that discriminate positively usually indicate a need for revision. (Author)

The number of online education courses available to those seeking higher education have been increasing exponentially, offering opportunities to students who would not otherwise have been able to do so, as well as offering options for those who may have been able to attend classes on campus, but would prefer to pursue their course of study at…

This exploratory research study examined the impact of using feedback from weekly multiple-choice tests on final exam scores and students' IDEA course ratings. The teacher researcher taught two sections (N=33; N=34) of a graduate-level, semester-long, online course in advanced human growth and development. Each section had identical course…
