Studied the effects of general referral information about a client on subsequent clinical inferences. Nursing students (N=54) were randomly assigned to "referral information" or "no referral information" conditions before being presented with additional data. Clinical inferential tasks included the assessment of maladjustment, client stress,…

Describes teaching students how to evaluate materials containing judgments based on a modification of a model by J. E. Sparks and C. Johnson called the pyramid of reading power. (EL)

This study considered differences in induction of biological properties between children and preadolescents based on differences in stimuli processing in these two groups. Two experiments tested predictions that young children, but not preadolescents, base their inductive inference on aggregating information from different sources rather than…

When studies are conducted over a period of time, the sample size typically decreases. In a study of the effects of exercise therapy and education with recovering congestive heart failure (CHF) patients (Brubaker, Witta, & Angelopoulus, 2003), the sample size decreased from over 40 to 9 participants after an 18-month time span. Although the…

Examined children's ability to settle causal relations and their capacity to make conclusions based on certain experiences and representations. Found that preschool children have a solid explanatory basis for their everyday life, within which facts are not generally accepted but are interpreted through a certain "logic," and the motives…

Contends that talking about texts in a conversational environment, during and after reading, allows students to think about a text and think about their thinking. Explains "conversation sparks," which push students to make a variety of type of comments that include predictions, questions, clarifications, and inferences. Concludes that giving…

Procedures based on latent trait models and the Rasch model are described for computation and asymptotic statistical inference for two decision consistency indexes often used in mastery or competence testing. Simulations were conducted for typical mastery testing situations to illustrate the procedures. (SLD)

Description of common errors found in the statistical methodologies of research carried out by librarians, focuses on sampling and generalizability. The discussion covers the need to either adapt library research to the statistical abilities of librarians or to educate librarians in the proper use of statistics. (15 references) (CLB)

Examines the usefulness of the Salience Imbalance Theory of metaphor processing to aid in understanding how children comprehend metaphors in written text. Supports the prediction that the measure of salience of features is affected by the topic order and vehicle (asymmetry), but also reports children's responses not explained by the theory. (KEH)

Describes the use of a simulated learning environment (SLE) as an instructional aid in teaching multivariate statistics, particularly inferential statistics. A prototype microcomputer-based SLE called MVWORLD developed at Drexel University for upper level statistics courses is explained, and implementing a statistics laboratory for multivariate…

The use of hierarchical models in social science research is discussed, with emphasis on causal inference and consideration of the limitations of hierarchical models. The increased use of Gibbs sampling and other Markov-chain Monte Carlo methods in the application of hierarchical models is recommended. (SLD)

A mental model analysis was conducted with 27 graduate and 29 undergraduate students in the statistical hypothesis testing domain to determine the nature of relevant mental models that can be taught to novices. Results suggest the efficacy of using separate and diagrammatic strategies in teaching novices introductory hypothesis testing. (SLD)

Aggressive and nonaggressive Latino and African-American adolescents read scenarios describing negative outcomes initiated by a hypothetical peer and made judgments about their reactions to the outcomes and about the peer's intentions. Data supported a model in which emotion mediates aggressive behavior. (BC)

The use of sampling weights in deriving population estimates for the National Assessment of Educational Progress (NAEP) and the effects of nonresponse and undercoverage on those estimates are described. The estimation of sampling variability from complex sample surveys is also reviewed, concentrating on the jackknife repeated replication…

Possible interpretive arguments for licensure and certification test scores are examined, and evidence to support each type of argument is analyzed. Particular attention is given to a competency-based argument that involves a sequence of inferences from test scores to statements about competence and then to conclusions about expected performance.…
