Summarizes a study that manipulated the race and sex of teacher applicants and organizational representatives to produce demographically similar and dissimilar pairings. Varied recruitment messages to reflect different groupings of homogeneous attributes related to economic incentives, work environment, or work itself. Racially similar pairings…

Provides evidence from a small northern U.S. city for Canadian raising, a Canadian phenomenon that heightens the onset of diphthongs in /ai/ and /au/ relative to the low central onset in neighboring dialects. Findings suggest that the Canadian diphthong varieties may not be conforming to the U.S. norm, but instead that the two varieties are…

Describes how a teacher used the "hypothesis-test" approach in elementary and junior high classrooms, teaching alone or team teaching, to be proactive about students needs instead of reactive to their disruptions or silence, to help kids who need it before they cry out, and to introduce them to the sweet taste of success before they encounter…

Proposes a research model to test the dependence of a field list of internationally visible journals on the initial set. Outlines applications of the experiment and hypothesizes on the validity of the Institute of Scientific Information's (ISI) impact factors. Suggests that in some cases lists of journals selected by linguistic or geographic…

Tested hypotheses linking global/analytic cognitive styles and aspects of researchers' problem-solving and related information-seeking behavior, based on a longitudinal study conducted in the United Sates and the United Kingdom that investigated the processes of mediated information retrieval searching during human information-seeking processes.…

Describes Project THEORIA, which was developed at Carnegie Mellon University to design interactive simulation environments for testing hypotheses and theories of the arts and human morals. Three projects in various stages of design and development are described: (1) "A Right to Die?; (2) "Art or Forgery?"; and (3) "Birth or…

A modification index is presented to aid in reformulating hypothetical models rejected after analysis of empirical data. This index is an improvement over the one in the LISREL V computer program in that it takes into account changes in all parameters of the model when one parameter is freed. (SLD)

Four measurement designs are presented for use with correlation coefficients corrected, in one variable, for attenuation due to unreliability (partially disattenuated). Associated asymptotic variance/covariance expressions are presented. Empirical simulation results illustrate the satisfactory Type I error control and statistical power of the…

Describes the Context Information System, a prototype retrieval system designed for online searching in an educational environment. Use of the system in Israeli high schools to encourage the development of research skills is discussed, emphasizing the use of databases for hypothesis testing and comparative analysis of data. (six references) (LRW)

Based on Luria-Das information processing theory, hypothesized that 26 educable mentally retarded children would score significantly less well on relatively pure measures of planning ability than would 13 younger average ability students after students were matched on cognitive processing ability. Hypothesis was not supported by study. (Author/NB)

Functional and structural relationship alternatives to the standard "F"-test for analysis of covariance (ANCOVA) are discussed for cases when the covariate is measured with error. An approximate statistical test based on the functional relationship approach is preferred on the basis of Monte Carlo simulation results. (SLD)

Describes study that was conducted to investigate the relationship between locus of control and user attitude toward computer based information systems (CBIS) used at work. The impact of user involvement is examined, the hypotheses tested are described, and implications for introducing CBIS into organizations are discussed. (14 references) (LRW)

Twenty-seven elementary-level special educators used frequent curriculum-based measurement to test their a priori hypotheses about the relative effectiveness of different teaching strategies. The teachers became less dogmatic in their beliefs about effective teaching strategies and were more accepting of the premise that teaching strategies are…

Compares experts', advanced students', and novice students' use of genetics knowledge to generate and test hypotheses while solving genetic pedigree problems. Reports that experts identified more critical cues, tested more hypotheses, were more rigorous in the falsification of alternative hypotheses, and were more flexible to their solving…

Hypothesis-formation skills were assessed for 40 graduate counseling students randomly assigned to training in either a divergent or convergent hypothesis-formation strategy. Findings suggest that trainees using a divergent strategy were able to formulate more comprehensive and multidimensional clinical hypotheses. Implications for training and…
