This document reports the results of a follow-up of a longitudinal, comparative study of Swedish children reared in center and home settings that are especially pertinent to the debate about the long-term effects of care on social development. The study began with a sample of 120 children from 12-18 months of age. Sixty infants were enrolled in…

Over 150 papers and articles were examined, and interviews with noted computer-based instruction (CBI) professionals were conducted to obtain information about CBI and the research evidence. Focus was on four main areas of CBI research--costs, learning achievements, individual differences, and student attitudes. Consistent empirical evidence did…

The topic of differential diagnosis and its application to the use of the Revised Illinois Test of Psycholinguistic Abilities (ITPA) and Wechsler Intelligence Scale for Children-Revised (WISC-R) is discussed. The theoretical bases for differential diagnosis and the properties of assessment instruments with diagnostic properties are presented.…

The study was undertaken at the suggestion of the Commission on Religion in Appalachia, a private development agency in Central Appalachia. Given limited resources and the difficulty of obtaining firsthand knowledge of the circumstances in the area, the commission wanted to measure socioeconomic status in the 60 Central Appalachian counties to…

Two questions are investigated here: What should the unit of analysis be in investigations of educational effects and on what basis should the units be chosen Under what conditions can relationships among measurements on individuals be estimated from the relationships among measurements on aggregates of individuals? Models using standard analysis…

The consistency/variability of error substitution patterns may hold important implications for subgrouping children with speech disorders, as well as for relationships between learning and generalization patterns. There is a need to quantify and examine the range of consistency/variability within the speech disordered population as it relates to…

Based on Bronfenbrenner's (1999) ecological perspective, a longitudinal, prospective model of individual differences in the quality of home environment (Home Observation for Measurement of the Environment--HOME) was tested in a sample of 179 Brazilian children and their families. Perinatal measures of family socioeconomic status (SES) and child…

The purpose of this study was to examine the effects of actively categorizing math problems on the math problem solving performance of students with and without attention deficit disorder (ADD). To this purpose, 52 fifth and sixth grade students were involved in actively categorizing or noncategorizing (control) tasks followed by two problem…

The study reported on in this article set out to replicate and extend Bardovi-Harlig and Dornyei's (1998) investigation of pragmatic awareness by addressing two research questions: (a) Do learners in English as a foreign language (EFL) and English as a second language (ESL) contexts display differences in their recognition and rating of pragmatic…

The main hypotheses addressed in the research were (1) whether imprecision in the phonological representations of lexical items underlies the impaired expressive naming abilities of disabled readers, and (2) whether weak verbal memory might mediate the relationship between naming and reading skills. From samples of 93 first graders and 67 fourth…

This study documented English acquisition by a group of Hmong adult immigrants over a period of one year, and explored the factors that appeared to be affecting their progress. Based on three measures (a test of listening comprehension, communication, fluency, reading, and writing; a pictured English vocabulary recognition test; and a written…

The four main approaches to measuring treatment effects in schools; raw gain, residual gain, covariance, and true scores; were compared. A simulation study showed true score analysis produced a large number of Type-I errors. When corrected for this error, this method showed the least power of the four. This outcome was clearly the result of the…

The multiple-choice science exercises used by the National Assessment of Educational Progress include an "I Don't Know" (IDK) alternative to estimate more accurately knowledge of groups of respondents. Group percentages of IDK responses were examined and compared with correct responses to see if the IDK introduces bias. Variance common…

Provides rationale for using trade books rather than textbooks for instruction in content areas. Describes a specific teaching strategy, which includes readiness, reading, and responses for encouraging the development of thinking skills and independent learning. (DST)

This paper focuses on a 1997 pilot project carried out in five secondary schools in South Africa that examined children's reading and information use. This study (n=958) was part of a larger study from 1995 and 1996 carried out in the United Kingdom. The primary goal was to examine what young people are reading at the end of the 20th century. The…
