Visual search studies with adults have shown that stimuli that contain a unique perceptual feature pop out from dissimilar distractors and are unaffected by the number of distractors. Studies with very young infants have suggested that they too might exhibit pop-out. However, infant studies have used paradigms in which pop-out is measured in…

We directly compared chimpanzee infants and human infants for categorical representations of three global-like categories (mammals, furniture and vehicles), using the familiarization-novelty preference technique. Neither species received any training during the experiments. We used the time that participants spent looking at the stimulus object…

A typical undergraduate biology curriculum covers a very large number of concepts and details. We describe the development of a Biology Concept Framework (BCF) as a possible way to organize this material to enhance teaching and learning. Our BCF is hierarchical, places details in context, nests related concepts, and articulates concepts that are…

Ever since Scriven (1967) and Bloom, Hastings, and Madaus (1971) articulated the distinction between summative and formative evaluation, "summative assessment" has referred to tests administered after learning is supposed to have occurred to determine whether it did. "Formative assessment", on the other hand, has been used to describe assessments…

This article discusses field tests that can be used in physical education programs. The most common field tests are anthropometric measurements, which include body mass index (BMI), girth measurements, and skinfold testing. Another field test that is gaining popularity is bioelectrical impedance analysis (BIA). Each method has particular strengths…

The question examined extensively in this document is why socioeconomic status and race are related to academic achievement. While most explanations look to the cognitive or cultural deficiencies of lower class and minority students, this volume considers an alternative explanation. Prevailing definitions of academic achievement undoubtedly…

Measuring student intelligence has been problematic in the United States since standardized testing first began in the early 1900s. The omnipresence of standardized testing in student populations is illustrated by the most popular contemporary tests which are used by some scholars to advance the notion that intelligence differences between whites…

This monograph provides an overview of the language situation in the three Baltic countries: Estonia, Latvia and Lithuania. It examines the recent change in language regimes that the Baltic States have deliberately brought about since the restitution of their independence, the nature of these changes, the opposition they have engendered and the…

Following a workshop on "Innovations in Employment Testing that Improve Validity and Reduce Adverse Impact," the City of Louisville (Kentucky) implemented a strategy to develop a comprehensive testing and recruiting program for police recruits. To improve candidate expectations and preparation, the following activities were undertaken:…

To study the home environment of the Puerto Rican as it relates to the children's academic achievement, 45 working class families were interviewed and these variables were investigated: achievement, classroom behavior inventory in relation to academic achievement, the effect of bilinguality on academic achievement, the influence of examiner…

New computer software for physics, mathematics, computer science, and statistics courses at North Carolina State University and in some high schools allows students to solve problems on the computer, recording every answer submitted to provide faculty with a record of student performance, and providing immediate feedback to students. Computerized…

The Nation's Report Card[TM] informs the public about the academic achievement of elementary and secondary students in the United States and its jurisdictions, including Puerto Rico. In 2003, a trial NAEP mathematics assessment was administered in Spanish to public school students at grades 4 and 8 in Puerto Rico. Based on preliminary analyses of…

Despite the increasing use of the microgenetic methodology to examine change, the techniques employed to analyse microgenetic data remain fairly unsophisticated. This paper reviews the existing ways of analysing such data and describes their limitations. We use two recent studies to illustrate how modelling can avoid these problems and reveal…

"Technology Counts 2007" looks back, and ahead, after a decade of enormous upheaval in the educational technology landscape. This special issue of "Education Week" includes the following articles: (1) A Digital Decade; (2) Getting Up to Speed (Andrew Trotter); (3) E-Rate's Imprint Seen in Schools (Andrew Trotter); (4) Teaching…

Background: Individual differences in conduct problems arise in part from proneness to anger/frustration and poor self-regulation of behavior. However, the genetic and environmental etiology of these connections is not known. Method: Using a twin design, we examined genetic and environmental covariation underlying the well-documented correlations…
