Reviews research into class size effects from a methodological viewpoint, concentrating on various strengths and weaknesses of randomized controlled trials (RCT) and observational studies. Discusses population definitions, causation, and generally sets out criteria for valid inferences from such studies. Illustrates with new findings from data in…

Examines the acquisition of tense and agreement by L2 learners of French. Interviews were conducted with English-speaking children acquiring French as a second language and with grade-matched native French-speaker controls. Results revealed that items encoding agreement emerged before items encoding tense, suggesting that the abstract grammatical…

Focuses on the importance of phonology in establishing orthographic representations. In normal readers, phonological and orthographic representations of words are so closely connected that they are usually coactivated, whereas in dyslexics, this connection is less strong, so that orthographic representations interfere less with phonemic…

Describes a computer-based instructional system called Stat Lady and reports the results of an evaluation study of undergraduates that tested the efficacy of learning probability from this program compared to a traditional lecture and a no-treatment control group. Aptitude treatment interaction is also investigated. (Author/LRW)

Describes how the University of Pennsylvania is testing a new way of teaching involving team-taught interdisciplinary courses on some its freshmen, while keeping others in a control group. (EV)

The primary purpose of this study was to determine the influence of Career Discovery I, the first module in a computer-assisted program for career decision-making, on the stability of the choice of college majors. This study sought to determine whether any differences existed in the stability of college majors between students who entered a…

The effects of a constructivist approach on academic achievement, self-concept and learning strategies, and student preference were investigated. The 76 six graders were divided into two groups. The experimental group was taught using the constructivist approach while the control group was taught using the traditional approach. A total of 40 hours…

This study examines the effects of attending religious revival services on the educational and behavioral outcomes of urban students. Specifically, the influence of attending the most recognized revival of the past decade is analyzed. Urban student attendees from throughout the United States attend, are surveyed, and then are randomly selected to…

American children spend an average of 6 hours and 32 minutes each day using various forms of media. Research has suggested that this high level of exposure has a negative impact on children's attitudes and behaviors. For example, media violence increases aggression in children, especially video games which allows children to be the aggressor and…

Using a conditioned suppression task, we investigated extinction and renewal of Pavlovian modulation in human sequential Feature Positive (FP) discrimination learning. In Experiment 1, in context a participants were first trained on two FP discriminations, X[right arrow]A+/A- and Y[right arrow]B+/B-. Extinction treatment was administered in the…

We report on a prospective longitudinal research programme exploring the connection between language acquisition deficits and dyslexia. The language development profile of children at-risk for dyslexia is compared to that of age-matched controls as well as of children who have been diagnosed with specific language impairment (SLI). The experiments…

There is little data available concerning the executive functions of children with dyslexia. The small number of existing studies in this field focus on single aspects of these functions such as working memory. The aim of the present study was therefore to assess a variety of aspects of executive functioning in children with dyslexia. Forty-two…

The present study addresses the reactivity of two types of verbal protocols in SLA research. It expands on the work of Leow and Morgan-Short (2004), who found nonmetalinguistic verbalization during a second-language reading task to be nonreactive for beginning learners' text comprehension, intake, and production of the targeted morphological form.…

Inagaki and Hatano (2002) have argued that young children initially understand biological phenomena in terms of vitalism, a mode of construal in which "life" or "life-force" is the central causal-explanatory concept. This study investigated the development of vitalistic reasoning in young children's concepts of life, the human body and death.…

The effect of the self-monitoring training on reading accuracy and fluency of second-grade poor readers was examined. The participants were assigned in one experimental and three control groups. The experimental group was reinforced with token-economy for self-correction and fluent reading. One control group practiced reading without feedback, the…
