The effectiveness of the Dwyer heart materials in facilitating learning and retention of information related to the heart under normal research conditions was investigated. Previous studies have focused on the manipulation of stimulus dimensions and not the effectiveness of the materials themselves. Data from three previous studies were compared…

Two methodological reviews of the Children's English and Services Study (CESS), a congressionally mandated estimate of the number and needs of limited English proficient children, are presented. Such reviews are needed because the CESS is the only national study of its kind which administered a language proficiency test to determine the language…

A 20-year study to monitor moral developmental stages is summarized with a focus on the invariant sequence and internal consistency of each stage. It is theorized that an individual passes through several stages in attaining moral judgment. As children grow older, they are able to integrate diverse points of view on a moral conflict. Each stage…

Along with cost, and hence availability of hardware and quality educational courseware, the major barrier to full implementation of microcomputers is the lack of knowledge possessed by researchers and educational practitioners alike regarding the nature of the knowledge, skills, and attitudes a teacher must have to successfully use microcomputers…

The theoretical background of the interdisciplinary Turko-Danish Fairytale Project is discussed in this paper. The paper first offers support for the working hypotheses of the Fairytale Project, which was designed to determine (1) if there are aesthetic principles that are universal and that guide the reader's experience of literary works; (2)…

This paper examined the rank transformation approach to analysis of variance as a solution to the Behrens-Fisher problem. Using simulation methodology four parameters were manipulated for the two group design: (1) ratio of population variances; (2) distribution form; (3) sample size and (4) population mean difference. The results indicated that…

A total of 72 children (including 24 educable retardates, 24 equal CA normals and 24 equal MA normals) were compared on a stimulus task under three modality switching conditions and two response modes. Error magnitudes for each testing situation are compared and implications of the results are stated. (SDH)

Program Evaluation and Review Techniques (PERT) is a network composed of events and activities, and a viable tool in developing a program for institutional research. The model contains three segments: internal and external research activities, and a system of data collection and retrieval. (Author/AJ)

The view is widely held that there exists a distinct set of social differences between youth and adults. This study examined perceptions of high school students in urban and rural centers in Alberta regarding the generation gap. (Editor)

The testing of research hypotheses is directly comparable to the dichotomous decision-making of medical diagnosis or jury trials--not ill/ill, or innocent/guilty decisions. There are costs in both kinds of error, type I errors of falsely rejecting a null hypothesis or type II errors of falsely rejecting an alternative hypothesis. It is important…

Exploratory research with large numbers of variables and even larger numbers of relationships is likely to result in frequent Type II errors; that is falsely accepting an incorrect null hypotheses. There are three ways of reducing Type II errors: (1) choosing a lower significance level, which then increases the probability of Type I error; (2)…

Hans-Georg Gadamer's development of the hermeneutic question points to the need for a hermeneutic consciousness in the United States appropriate for human communication research. Communication studies in the United States have taken a route very different from hermeneutics. They are based on attempts to understand the subjective intentions of a…

This handbook was produced to address some of the questions raised at a workshop for producers, programmers, performers, researchers, and writers in the field of Canadian children's television. Three main areas are covered. The first section provides an indication of some of the information that research can supply for the improvement of…
