Investigates effects of illustrations on 11-year-olds' comprehension of abstract and concrete passages. Reveals no significant effects due to the illustrations, although ability effects were found for literal, inferential, and total comprehension. (DF)

A student's understanding of a problem before he or she solves it is a critical component of successful problem solving. This understanding is based on how a problem is represented; that is, whether a problem is understood in terms of principles or solution methods or whether the focus is on features that are irrelevant to its solution. In this…

Bootstrap analysis, both for nonparametric statistical inference and for describing sample results stability and replicability, has been gaining prominence among quantitative researchers in educational and psychological research. Procedurally, however, it is often quite a challenge for quantitative researchers to implement bootstrap analysis in…

Used latent class analysis to test statistically Siegler's rule assessment methodology, the number of rules needed to fit a set of data. Found that rules can be identified, that some are different from those proposed by Siegler, the correct rule is not acquired by subjects, and that the rules in the transitional period are difficult to identify.…

Examines potential problems in the use of inferential statistics for single population proportions, differences between two population proportions, and quotients of two population proportions. Discusses hypothesis testing versus interval estimation. Emphasizes the importance of selecting the appropriate formula for the standard error and…

Discusses creativity, play, and nonconformity in children, including the illusion of thought disorder or abnormality, and aspects of everyday creativity, health, and survival. Describes creative divergence, chaotic amplification, the evolution of information, and primitive cognitive processes. Concludes with a discussion of cognitive styles,…

Research has shown that attributional styles are affected by the attributor's culture, inferential goals, and level of cognitive processing. This study compares the attributions made in sports articles and editorials of newspapers published in Hong Kong and the United States. Implications for the mixed model of social inference are discussed. (LSR)

Investigates relations among students' interest in texts, self assessments, and comprehension performance. States that 31 college students read expository texts and--after providing an interest rating and a confidence rating in answering inferences generated from passages on domains--rated texts and completed true/false comprehension questions.…

Distinguishes two conceptions of sample and sampling that emerged in the context of a teaching experiment conducted in a high school statistics class. Suggests that the conception of a sample as a quasi- proportional, small-scale version of the population is a powerful one to target for instruction. (Author/KHR)

Presents and discusses examples that illustrate the nature and scope of elementary and middle school students' reasoning when they are faced with tasks that involve making inferences and predictions from data. Shows that the range in thinking is not so much dependent on age as on the experiences students have in data exploration. (KHR)

Argues that, given a document and a query, users first judge the document against the individual concepts in the query and then use some inferencing process to derive a compound judgment for the entire query. The research examines the relative effectiveness of probabilistic and fuzzy models at predicting users' compound judgments. (23 references)…

Discusses three topics related to interpretation of discriminant analyses (DA's): (1) partial F ratios and partial Wilks's lambdas for predictor variables in standard, step-down, and stepwise DA's; (2) relation of goals of classification to definition/evaluation of classification rules; and (3) significance tests for total hit rates in internal…

Describes 45 third graders'"dramatic literacy" and the modal sources for inferences. Finds that (1) the more children used visual cues, the more they used verbal and psychological cues; and (2) inferences about the play's theme were related to aural recall of thematic dialogue and what children reported learning from the play. (SR)

Results of five studies suggest that the availability of an object concept in sentences that preceded an unexpected story outcome was a critical determinant of the occurrence of an object inference. The thematic prominence of the object influences the use of the object in an inference. (RH)

Discusses the extent to which computers can understand natural language. Considers assertions that computers can be described as literate, and considers more generally the purpose of designing machines which perform like humans. (RS)
