Individuals can partly recreate the "wisdom of crowds" within their own minds by combining nonredundant estimates they themselves have generated. Herzog and Hertwig (2009) showed that this accuracy gain could be boosted by urging people to actively think differently when generating a 2nd estimate ("dialectical bootstrapping").…

The standard error of equating quantifies the variability in the estimation of an equating function. Because common items for deriving equated scores are treated as fixed, the only source of variability typically considered arises from the estimation of common-item parameters from responses of samples of examinees. Use of alternative, equally…

Utilizing planned missing data (PMD) designs (ex. 3-form surveys) enables researchers to ask participants fewer questions during the data collection process. An important question, however, is just how few participants are needed to effectively employ planned missing data designs in research studies. This article explores this question by using…

There are two primary challenges for instructors in offering a high-quality course at large scale. The first is scaling educational experiences to such a large audience. The second major challenge encountered is that of enabling adaptivity of the educational experience. This thesis addresses both major challenges in the way of high-quality…

Within the framework of foreign language teaching and learning, reading strategies, depth of vocabulary knowledge and text inferencing skills have not been researched extensively. This study tries to fill this gap by analyzing the effects of reading strategies used by Turkish EFL learners and their depth of vocabulary knowledge on their text…

Readers differentially adopt an agent's perspective as a function of pronouns encountered during reading. The present study assessed the reliability of this effect across narrative contexts and self-reported variation in levels of engagement during reading. Experiment 1 used an extended sample (N = 263) and replicated an interactive influence of…

In this investigation, we used Texas statewide data to determine the extent to which inequities were present in the assignment of school disciplinary consequences. Specifically examined were the assignment of in-school suspension, out-of-school suspension, and disciplinary alternative education program placement to grade 6 Black, Hispanic, and…

This study relates to the results obtained in the development of reading comprehension (RC) and self-concept as a reader in students who participated in "Llegim en parella" ("Reading in pairs"), a Catalan peer tutoring programme. The research combines a quasi-experimental design with the use of comparison groups and…

This article describes a cooperative writing response initiative designed to develop writing skills in foreign/second-language contexts (hereafter L2). The strategy originated from my desire to cater for my learners' need to become better writers in English within a constrained educational environment in Argentina. In this article I describe this…

We investigated component language and cognitive skills of oral language comprehension of narrative texts (i.e., listening comprehension). Using the construction--integration model of text comprehension as an overarching theoretical framework, we examined direct and mediated relations of foundational cognitive skills (working memory and…

As widespread as Science, Technology, Engineering, and Math (STEM) initiatives and reforms are today in education, a rudimentary problem with these endeavors is being overlooked. In general, education programs and school districts are failing to ensure that elementary teachers who provide children's early academic experiences have the appropriate…

The purpose of this paper is to illustrate alpha's robustness and usefulness, using actual and simulated educational test data. The sampling properties of alpha are compared with the sampling properties of several other reliability coefficients: Guttman's lambda[subscript 2], lambda[subscript 4], and lambda[subscript 6]; test-retest reliability;…

Close reading is the methodical investigation of a complex text through answering text dependent questions geared to unpack the text's meaning. Close reading directs students to examine and analyze the text through a series of activities that focus students on the meanings of individual words and sentences as well as the overall development of…

Our goal in the present study was to evaluate the claim that category labels affect children's judgments of visual similarity. We presented preschool children with discriminable and identical sets of animal pictures and asked them to make perceptual judgments in the presence or absence of labels. Our findings indicate that children who are asked…

The study tests the hypothesis that conditional probability judgments can be influenced by causal links between the target event and the evidence even when the statistical relations among variables are held constant. Three experiments varied the causal structure relating three variables and found that (a) the target event was perceived as more…
