A substantial proportion of trial registrations are not linked to corresponding published articles, limiting analyses and new tools. Our aim was to develop a method for finding articles reporting the results of trials that are registered on ClinicalTrials.gov when they do not include metadata links. We used a set of 27,280 trial registration and…

Meta-analyses are an important tool within systematic reviews to estimate the overall effect size and its confidence interval for an outcome of interest. If heterogeneity between the results of the relevant studies is anticipated, then a random-effects model is often preferred for analysis. In this model, a prediction interval for the true effect…

Purpose: We report the results of a systematic review and meta-analysis investigating the relationship between perceptual anchoring and dyslexia. Our goal was to assess the direction and degree of the effect between perceptual anchoring and reading ability in typical and atypical (i.e., dyslexic) readers. Method: We performed a literature search…

We reviewed 14 experimental studies comparing different preference assessments for individuals with developmental disabilities that were published in peer-reviewed journals between 1985 and 2012. Studies were summarized based on the following six variables: (a) the number of participants, (b) the type of disability, (c) the number and type of…

Formality has long been of interest in the study of discourse, with periodic discussions of the best measure of formality and the relationship between formality and text categories. In this research, we explored what features predict formality as humans perceive the construct. We categorized a corpus consisting of 1,158 discourse samples published…

Previous work on the long-term effects of early reading focuses on whether children can read early (i.e. capability) not on whether this is beneficial (i.e. optimality). The Luke Effect is introduced to predict long-term reading development as a function of when children learn to read. A review of correlational, intervention, and comparative…

This article describes the ICAP framework that defines cognitive engagement activities on the basis of students' overt behaviors and proposes that engagement behaviors can be categorized and differentiated into one of four modes: "Interactive," "Constructive," "Active," and "Passive." The ICAP hypothesis…

In 1996, Californians overwhelmingly approved Proposition 209, which prohibited all state agencies from discriminating on the basis of race, ethnicity, or gender in university admissions, public employment, or competition for a state contract. Opponents of Proposition 209 predicted dire consequences for California's ethnic minorities and women if…

Explains chaos theory; compares a conventional instructional systems design (ISD) approach with chaos theory and dynamic nonlinear systems, including deterministic predictability and indeterministic unpredictability and negative and positive feedback; explores theoretical implications for developing an alternative ISD model; and recommends future…

This paper describes a critical study of the available forecasts and forecasting studies for the home video player market over a 15-year period which was undertaken to discover why so many forecasts were wrong about consumer adoption of home videocassette players and videodisk players, the reasons for these errors, and ways in which this knowledge…

Clarifies appropriateness of certain simulation approaches by distinguishing between different types of simulations--experimental, predictive, evaluative, and educational--on the basis of purpose, assumptions, procedures, and criteria for evaluating. The kinds of questions each type best responds to are discussed. (65 references) (MBR)

This report provides an analysis of microcomputer software available for elementary and secondary level instruction in 1989 as compared to 1984. Data from the Resources in Computer Education (RICE) database are used to compare distribution of software programs by grade level; hardware manufacturer; application type (drill, tutorial, simulation,…

Proposes and briefly discusses several hypotheses concerning the unique developmental status of peer relations in the first three years of life. Analyzes the meaning of individual differences in very early peer competencies. Suggests that developmental differences in peer relations might translate into hypotheses regarding early individual…

This paper reports on a study that asked six groups (totalling 175 third-year medical students), before taking their surgery clerkship, to make predictions about their experiences in the clerkship. For male students, those in the high-expectation group had records of consistently higher mean academic performance in their first 2 years of medical…

Presents results from the 1992 Drug Use Forecasting (DUF) program that measures illicit drug use among persons arrested for criminal behavior. Adult use of specific drugs, male juvenile drug use, and the role of the DUF are explored. (GLR)
