This article presents a study on the use of multimedia technology for the teaching of Form (Grade) One history, which is a form of narrative subject in nature. Specifically, it is to study the viability of multimedia materials in supporting active learning for subjects which are in narrative form. Due to the scarcity of interactive multimedia…

Purpose: There is much hype about academics' attitude to Wikipedia. This paper seeks to go beyond anecdotal evidence by drawing on empirical research to ascertain how academics respond to Wikipedia and the implications these responses have for the take-up of Web 2.0+. It aims to test the hypothesis that Web 2.0+, as a platform built around the…

With widespread adoption of computer-based distance education as a mission-critical component of the institution's educational program, the need for evaluation has emerged. In this research, we aim to expand on the systems approach by offering a model for evaluation based on socio-technical systems theory addressing a stated need in the literature…

Multinomial processing tree models are widely used in many areas of psychology. Their application relies on the assumption of parameter homogeneity, that is, on the assumption that participants do not differ in their parameter values. Tests for parameter homogeneity are proposed that can be routinely used as part of multinomial model analyses to…

An illustration of a test for independence was provided with a mixed set of variables. The matrix consisted of 10 tests of interest and four random deviates in which the relationship between sets was demonstrated to be minimal. The result was discussed for a situation in which factoring methods might be considered. (Author)

A longstanding belief has been that a distribution can be assumed symmetric if the mean and median are coincidental. Coincidence of mean and median is a necessary but not sufficient condition for symmetry. Two counter examples proving this point are provided. Plotting of the data and third moment computation are recommended alternatives.…

There are a variety of statistical problems which involve the use of the non-central t-distribution. The development of tables for the non-central t-distribution has been hindered by the number of parameters involved. Several approaches to this task have been made in the literature, characterized by either focusing attention on the subset of…

The kappa coefficient and the chi square statistic are used as indices of agreement between two judges' ratings of a set of stimuli on a nominal scale. In this article, the logic of these indices is extended to weighted multi-way cases. (Author/JKS)

It is shown that the rank-biserial correlation coefficient is a linear function of the U-statistic (Mann and Whitney), so that a test of group mean difference is equivalent to a test of zero correlation for the rank-biserial coefficient. (RC)

Exact conditional tests of independence in cross-classification tables are formulated based on chi square and other statistics with stronger operational interpretations, such as some nominal and ordinal measures of association. Guidelines for table dimensions and sample sizes for which the tests are economically implemented on a computer are…

Presents two experiments concerning confirmatory bias in the way counselors collect data to test their hypotheses. Counselors were asked either to develop their own clinical hypothesis or were given a hypothesis to test. Confirmatory bias in hypothesis testing was not supported in either experiment. (JAC)

An exact probability test for use with certain Likert-type scales is presented. The procedure assumes equally-spaced points, independence of subjects' responses, and that each point has an equal likelihood of response for each subject. Tables for critical values are presented. (Author/JKS)

A procedure is specified for testing the significance of predicted trends in k independent correlations. An example is also provided for illustrative purposes. (Author)
