Discusses when one can infer children's use of a rule, the mechanisms underlying the development of rule use, and the relation between understanding and execution. Contrasts relational complexity theory with cognitive complexity and control theory. (Author/KB)

This study examined language and fluency characteristics of single-utterance (SU) and multiple-utterance (MU)conversational turns produced by 15 preschoolers who stutter and 15 nonstuttering peers. Results suggest that MU turns are demanding for young children because they evoke relatively long and complex utterances and that clinicians should…

Strategy use, task performance, and perceptions of difficulty were studied for 34 mildly retarded children and 34 who were not retarded. Results showed that retarded children rated tasks more difficult than nonretarded students and responded less well to brief task training. Metacognitive variables predicted recall performance independently of…

Results of three experiments support the conclusion that tasks involving the localization of objects or events from mirror images are not direct indices of self-recognition among children between 14 and 22 months of age. Rather, they indicate the skill of infants in using the mirror as a perceptual tool. (RH)

Tests the effects that many photographers believe color and complexity have on how people process the information in photographs. Finds that images with color and more complex elements were easier to remember, and that complexity did not result in more (reported) mental effort. (SR)

Describes a framework for designing an electronic performance support system (EPSS) that reduces the requirement for more traditional forms of training. An intervention summary table is provided that includes five types of interventions, user access, user type (expert and/or novice), purpose, and difficulty. (Author/LRW)

In this article, the author talks about the texts of Jacques Derrida and Dewey. The texts of Jacques Derrida seem inextricably connected to the word deconstruction, yet, Derrida insists, "The word "deconstruction," like all other words, acquires its value only from its inscription in a chain of possible substitutions." The author argues that…

The Common European Framework of Reference (CEFR) posits six levels of proficiency and defines these largely in relation to empirically derived difficulty estimates based on stakeholder perceptions of what language functions expressed by 'Can-do' statements can be successfully performed at each level. Though also containing much valuable…

Confidence-accuracy (CA) calibration was examined for absolute and relative face recognition judgments as well as for recognition judgments from groups of stimuli presented simultaneously or sequentially (i.e., simultaneous or sequential mini-lineups). When the effect of difficulty was controlled, absolute and relative judgments produced…

The objective of this study was to explore factors that affect the difficulty of counterfactual reasoning in 3-5-year-old children and to shed light on the reason why counterfactual reasoning relates to understanding false belief [Cognitive Development, 13 (1998) 73-90]. Using travel scenarios, the difference between simple scenarios, in which…

Learning mathematics has been recognized by many as important. It does not only develop students' ability to think in quantitative terms but can also enhance skills such as analytical and problem solving skills. However, to enable us to tell our students how important mathematics is we have to understand students' beliefs in learning mathematics…

This document is one of eight reports prepared to support the development of a new learning system, a development effort that is the first step in a major initiative undertaken by the Stupski Foundation. This report synthesizes recent research and theoretical literature on effective pedagogy for the Stupski Foundation's 2009 initiative of…

This article examines nonmathematical linguistic complexity as a source of differential item functioning (DIF) in math word problems for English language learners (ELLs). Specifically, this study investigates the relationship between item measures of linguistic complexity, nonlinguistic forms of representation and DIF measures based on item…

In this paper the academic English reading proficiency of 578 Norwegian university students was quantitatively examined. Self-assessment items were used to measure reading proficiency in Norwegian and English and validated using an International English Language Testing System Academic Reading Module. The study found that about 30% of the…

The purpose of this qualitative case study was to examine the uses of informational texts within an ethnically diverse, second grade classroom and how the teacher carefully scaffolded students' developing understandings about these texts. A community of practice theoretical framework was employed to better understand the ways in which…
