Three analyses of pretest and posttest data are considered: (1) posttest only designs; (2) two-way repeated measures of analysis of variance (ANOVA); and (3) one-way analysis of covariance (ANCOVA). Conditions that ensure legitimacy of inferences about the equality of treatment effects on the latent variable theta are discussed. (SLD)

Examines the effect of feedback on helping poor readers improve their comprehension. Compares the effects of instruction about text-based inferencing using explicit, process-explaining feedback to effects of using feedback that did not describe how to draw inferences. Finds that both instructional conditions boosted overall comprehension, but…

A Bayesian alternative to interpretations based on classical reliability theory is presented. Procedures are detailed for calculation of a posterior score and credible interval with joint consideration of item sample and occasion error. (Author/SLD)

Compares preschool and first grade children's ability to make three types of inferences: script-based inferences, invited inferences, and logical inferences. Finds preschoolers better able to make script-based inferences and first graders better able to draw script-based and invited inferences. Suggests that children's ability to draw inferences…

Results of four studies confirmed the hypothesis that three year olds would have less difficulty inferring that another person holds an odd belief about a matter of taste or value than they have in inferring that another person holds a false belief about a matter of verifiable fact. (RH)

Examines whether vocabulary acquisition in a foreign language by inferring the meaning of a word from its context makes an important contribution toward the retention of the word in question so long as the meaning is correctly guessed. (49 references) (GLR)

Five experiments involving 173 college students show that people frequently do not apply the category inclusion rule when evaluating categorical arguments involving natural categories and a single nonexplainable predicate. Judgments tended to be proportional to the similarity between premise and conclusion categories. (SLD)

Investigates conscious understanding during narrative comprehension as revealed through use of think-aloud methodology. Presents an analytical model of conscious understanding. Identifies three working memory operations in the protocols--operations which are functionally necessary to inferences in the protocols. Discusses data and current models…

Investigated the validity of inferences from A. Jensen's method of studying group differences on cognitive tests (1985) and compared the validity of inferences to inferences based on multi-group confirmatory factor analysis using constructed population covariance matrices. Results show the insensitivity of Jensen's method and the superiority of…

Two experiments examined toddlers' ability to use cues to infer meaning of novel action words. Toddlers were taught labels for similar or dissimilar pairs of videotaped actions, with behavioral cues or eye gaze related to agents' intentions distinguishing similar events. Results showed that in year 2, children begin to consider…

Three studies examined the capacity of 4-year olds, kindergartners, second- and fifth graders, and adults to use trait labels (nice, mean, shy, not shy) as tools for making inferences about mental states. Findings suggested that even for 4-year olds, trait labels can serve as a basis for making non-obvious inferences. (Author/KB)

Examined 7- to 10-year-olds' ability to acquire a domain-general processing strategy--Control of Variables Strategy (CVS)-- and make valid inferences. Found that with explicit training within domains and probe questions, children could learn and transfer the CVS. Probes without direct instruction did not improve CVS and inferential thinking…

Four studies compared preschoolers' fast mapping of new proper and common names following indirect exposures requiring inference with their learning new names following ostensive cues. Found that inferential learning of names and learning by direct instruction were largely equivalent: learning from a situation with clear joint references…

Using Microsoft Excel, several interactive, computerized learning modules are developed to demonstrate the Central Limit Theorem. These modules are used in the classroom to enhance the comprehension of this theorem. The Central Limit Theorem is a very important theorem in statistics, and yet because it is not intuitively obvious, statistics…

Children's acquisition of vocabulary is essential for gains in reading comprehension and reading development. Struggling readers often do not make gains in their reading comprehension because they have a limited reading vocabulary. Enhancing the vocabulary development and growth for children who are experiencing reading difficulties enables them…
