In this article, we describe and evaluate a Web-based interactive tutorial used to present hypothesis testing concepts. The tutorial includes multiple-choice questions with feedback, an interactive applet that allows students to draw samples and evaluate null hypotheses, and follow-up questions suitable for grading. Students either used the…

The present research evaluated an intervention, derived from the "extended contact hypothesis," which aimed to change children's intergroup attitudes toward refugees. The study (n=253) tested 3 models of extended contact among 5- to 11-year-old children: dual identity, common ingroup identity, and decategorization. Children read friendship stories…

On the basis of predictions from social comparison theory (L. Festinger, 1954) and informed by findings from the social comparison and eating disorder literatures, hypotheses were tested regarding the social comparison behaviors of women with eating disorder symptoms and their asymptomatic peers. Results indicated differentiating social-cognitive…

Eight experiments investigated the effects of visual, spatial, auditory, and executive interference on the symbolic comparison of animal size and ferocity, semantic goodness of words, and numbers. Dynamic visual noise (DVN) and the reading of visually presented stimulus items were shown to selectively interfere with response times on the animal…

In recent work by Tsimpli (2003) and Tsimpli and Dimitrakopoulou (to appear) an explicit claim is made about the nature of end-state grammars in older second language (L2) learners: uninterpretable syntactic features that have not been selected during first language (L1) acquisition will not be available for L2 grammar construction. Interpretable…

A survey of the collections of the libraries at the State University College at Buffalo (New York) was conducted to determine the physical condition of books and bound periodicals. The methodology of prior surveys at Yale (Connecticut) and Syracuse (New York) Universities was used and the following hypotheses were tested: (1) the methodology used…

The Mantel-Haenszel procedure (MH) is a practical, inexpensive, and powerful way to detect test items that function differently in two groups of examinees. MH is a natural outgrowth of previously suggested chi square methods, and it is also related to methods based on item response theory. The study of items that function differently for two…

A Monte Carlo Study was conducted to evaluate six models commonly used to evaluate change. The results revealed specific problems with each. Analysis of covariance and analysis of variance of residualized gain scores appeared to substantially and consistently overestimate the change effects. Multiple factor analysis of variance models utilizing…

Utilizing data derived from 277 rural, male respondents initially enrolled in Lenawee County, Michigan high schools, the Rotter's Internal-External Locus of Control Scale was employed to test the hypothesis that locus of control will have interactive rather than additive effects on the process of status attainment. Locus of control was defined as…

IN ORDER TO EXAMINE THE RELATIONSHIP BETWEEN FORMAL LIBRARY EDUCATION AND EFFECTIVENESS IN ANSWERING REFERENCE QUESTIONS, FIELD STUDIES WERE CONDUCTED IN WHICH 9 PAIRS OF REFERENCE STAFF MEMBERS IN MEDIUM-SIZED PUBLIC LIBRARIES WERE ASKED A SET OF TEST REFERENCE QUESTIONS AND OBSERVED WHILE THEY ANSWERED THEM. MAJOR CONCLUSIONS WERE THAT--(1) THE…

Studies pertaining to community growth have dealt with the community's territorial expansion, economy, government's functions, and institutions. Since researchers usually use the dimension that they have been taught (economists use economic measures, and social scientists use sociological measures), two problems have resulted: (1) How should…

A study was conducted to (1) Analyze the context, structure, and performance of two community junior colleges in Florida, and (2) Determine the extent that the relationships established were consistent with Hage's axiomatic theory of organizations and Pugh's multivariate analysis of 52 organizations. A survey of authoritative literature and…

Outlines six activities for grades six through nine designed to illustrate the processes used by archaeologists. These processes include observation, comparison, classification, communication, use of numbers, and hypothesis formation. (AM)

Compared the results of the adult learning of English as a Foreign Language (EFL) using an inductive approach as opposed to a deductive one based on explicit contrastive analysis (CA) input. It is suggested that a deductive approach that uses CA input in EFL teaching and learning materials is more effective in minimizing error rates. (54…

Presents a model that suggests the cognitive style and personality traits that are likely to affect programming stages and empirically investigates 1 portion of that model with 192 college students. Correlations between results from the Group Embedded Figures Test and design and coding tasks are discussed. (LRW)
