Describes hypothesis validity as extent to which research results reflect theoretically derived predictions about relations between or among constructs. Discusses role of hypotheses in theory testing. Presents four threats to hypothesis validity: (1) inconsequential research hypotheses; (2) ambiguous research hypotheses; (3) noncongruence of…

Presents a didactic collection of covariance and mean structure hypotheses that can be tested using a widely applicable and easy to use structural equation modeling approach. The method is useful when the goal is to examine the observed multivariable structure or test hypotheses regarding interrelationships in measures and when large samples are…

Proposes a procedure for testing hypotheses regarding the dispersion of responses distributed over taxa that uses the distribution of the number of cells that are empty or are singly occupied. Presents a table showing the number of cases needed to achieve 0.10, 0.05, and 0.01 significance for excessive numbers of empty cells. (SLD)

Outlines an exploratory multidimensional scaling-based approach to profile analysis called Profile Analysis via Multidimensional Scaling (PAMS) (M. Davison, 1994). The PAMS model has the advantages of being applied to samples of any size easily, classifying persons on a continuum, and using person profile index for further hypothesis studies, but…

A model of cue-based probability judgment is developed within the framework of support theory. Cue diagnosticity is evaluated from experience as represented by error-free frequency counts. When presented with a pattern of cues, the diagnostic implications of each cue are assessed independently and then summed to arrive at an assessment of the…

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…

Our purpose is to offer children tasks so they can make drawings as diverse and different from each other whilst trying to avoid imitation. Achieving this goal involves the increase of children's creativity. The paper is theoretically based on the consideration of creativity as the ability to create "something new, original, and in accordance…

This paper explores the idea of perceived value of educational hypermedia by extending prior research in advertising and information systems. It proposes that the value of a course support site comes from both its information content and users' experience when they visit the site. The cognitive antecedents of a site's perceived value include…

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…

With research showing the benefits of self-directed learning, more activities are needed to provide learners opportunities for self-directed practice (Khomson, 1997; Lee, 1998; Phongnapharuk, 2007). A 12-week experimental study was performed with 80 EFL learners; one group contained 40 Communication Arts students and the other one consisted of 40…

This study explored career pathways for becoming an athletic director (AD) at National Collegiate Athletic Association (NCAA) Divisions I, II, and, III member institutions with consideration of gender and race/ethnicity. The study employed an exploratory, descriptive research design using a quantitative electronic survey tapping a census of all…

This paper reports a systematic literature review examining empirical studies on the effects of peer assessment for learning. Peer assessment is fundamentally a social process whose core activity is feedback given to and received from others, aimed at enhancing the performance of each individual group member and/or the group as a whole. This makes…

This article deals with reasons for the motivation to study in higher education. To find out about motives, around 200 A-level students in Germany and Great Britain were asked about their plans for the time after completion of their A-levels. Through socio-demographic data the authors could deploy facts about social backgrounds and the…
