Describes a study of 61 undergraduates that investigated the effects of hypermedia content-structure focusing on learner's structural knowledge acquisition, retention, and disorientation. Use of a Completely Randomized Multivariate Analysis of Variance design for hypothesis testing is explained and implications for hypermedia design are discussed.…

This study compared the effects of intrinsic relevance with embedded, extrinsic relevance-enhancing strategies based on the ARCS (attention, relevance, confidence, and satisfaction) model of instruction on perceived motivation and the learning outcomes of identification, terminology, comprehension, and drawing. Both intrinsic and extrinsic…

The first of three articles reports the effectiveness of a feature-matching approach to computer retrieval of graphic information. The second discusses the use of multivariate techniques to measure perceived complexity of database searching by users. The third explores the limitations of user consultation in database design.

Analyzes a sample of over 4,700 orders for library materials at the University of California, Berkeley, in terms of the probability that the material will arrive and the factors that determine arrival. Models to evaluate the book ordering process are presented, and variables that may affect arrival time are discussed. (six references) (Author/LRW)

Describes a study conducted at the University of Calgary (Alberta) that investigated student perceptions of an audio-teleconferencing course and compared them with instructor perceptions from an earlier study. The Q-Sort instrument used in the study is explained, and results of cluster analysis are discussed. (Contains 10 references.) (LRW)

Discussion of the writing process of elementary students with learning disabilities focuses on studies of a HyperCard stack that was developed to help beginning writers and their teachers. Texts created with the hypermedia are compared with texts created using paper and pencil and word processing. (Author/LRW)

Variance formulas of H. E. Daniels and M. G. Kendall (1947) are generalized to allow for the presence of ties and variance of the sample tau correlation. Applications of these generalized formulas are discussed and illustrated using data from a 1965 study of contraceptive use in 15 developing countries. (SLD)

Reports on a set of three studies that compared responses to commonly used attitude and personality questionnaires administered by computer with those administered in written form. Subjects' affective reactions to the two modes of administration were also examined. Overall the differences between the two conditions were negligible. (25 references)…

The general-information-theoretic approach was used to identify informational overlap and asymmetry between variables, using affective, cognitive, and behavioral measures. Using the chi-squared test, no significant differences were found in response rates, demographics, or patronage frequency of three stores between numerical (n=453) and graphic…

This study examined whether differences exist in the adjustment of young adults in community settings across levels of mental retardation for four dependent variables, using parametric multivariate analysis of variance, nonparametric multivariate analysis of variance, multiple nonparametric analyses of variance, and multinomial logistic…

Discussion of the use of technology in distance education courses focuses on the evaluation of a two-week teaching trial between two college campuses in Australia that used compressed data interactive videoconferencing technology. Results for the adequacy of the physical presentation and student and staff perceptions are detailed. (14 references)…

Applying multivariate statistical techniques to a nationally representative sample of 687 students at historically black colleges and universities (HBCU) and 742 students at traditionally white institutions, this study finds that HBCU may have an educational justification, in that African American students at HBCU are more likely to pursue…

Objective: The aim of this paper is to examine some of the factors that facilitate and hinder interagency collaboration between child protection services and mental health services in cases where there is a parent with a mental illness and there are protection concerns for the child(ren). The paper reports on agency practices, worker attitudes and…

This study examined the relations between school climate and school adjustment among 101 lesbian, gay, and bisexual (LGB) high school students and the moderating influence of social support on those relations. Students completed surveys to assess three aspects of the school climate (the school's exclusion/inclusion of LGB people, personal…

There is limited research on the relationship between adolescent smoking and related social and psychological factors, but it is known that adolescent tobacco users are at higher risk for behavioral disorders and substance abuse. Of great interest to those who work in youth tobacco prevention is expanding knowledge about those factors that lead to…
