Secondary analysis of datasets can extend previous work in the field, provide a greater quantity of material, and has the advantages of speed and lower cost. More use of secondary data could improve the low esteem of educational research. (Contains 15 references.) (SK)

The frequencies of pervasive developmental disorder (PDD) in Down's syndrome (DS) have been reported from 1% to 11%. However, it is not clear if the frequency of this co-occurrence is higher or lower than in other mental retardations. We study a large sample of DS population, finding a PDD frequency of 15.6%, with 5.58% of autism (eight males and…

The Board of Trustees of the Dallas Independent School District (DISD) asked the Council of the Great City Schools, the nation's primary coalition of large urban school systems, to examine the staffing levels of the school system and determine whether the numbers of staff members employed were appropriate for a district serving as many students as…

In January of 2002, President George W. Bush signed into law the "No Child Left Behind Act" of 2001 (NCLB). NCLB, which passed through Congress with overwhelming support from both Republican and Democratic members, was predicated on four basic objectives to address pervasive problems within America's public schools: (1) school…

Background/Context: Much research is being done on Turkish immigrants and their children in Germany and the Netherlands, but almost always from a national perspective. To compare the situation, for example, regarding educational outcomes across the two countries has proved to be very difficult because of different sets, selection criteria, and…

In this paper, we exploit a high school pilot scheme to identify the causal effect of advanced high school math on labor market outcomes. The pilot scheme reduced the costs of choosing advanced math because it allowed for a more flexible combination of math with other courses. We find clear evidence of a causal relationship between math and…

This report describes the machine-readable data and tabulating routines that the Bureau of Labor Statistics (BLS) is prepared to distribute. An introduction discusses the LABSTAT (Labor Statistics) database and the BLS policy on release of unpublished data. Descriptions summarizing data stored in 25 files follow this format: overview, data…

This report summarizes the findings and describes the products of a 2-part research project that examined the parameters of Washington's interlibrary loan cooperation statewide, and developed a set of computer models to be used in simulation studies of associated activities and policies. It contains a statement of the problem; an historical…

Proceedings of a study group that considered the utility of the Higher Education General Information Survey (HEGIS) finance data for institutional and higher educational sector comparisons are presented, as are issue papers and descriptive information. The study group of representatives from higher education institutions and organizations outlined…

The data collected for this report can be divided into three segments: a 14-year collection, 1950-51 through 1963-64, on which analyses were performed and the original predictions generated; a six-year follow-up stage, beginning in 1964-65; a twenty-year collection, 1950-51 through 1969-70, from which new predictions were generated; and a…

Introduces two data distortion methods (Frequency-Imposed Distortion, Frequency-Imposed Probability Distortion) and uses a Monte Carlo study to compare their performance with that of other distortion methods (Point Distortion, Probability Distortion). Indications that data generated by these two methods produce accurate statistics and protect…

A 2008 statement from the Foundation for California Community Colleges in the Chronicle of Higher Education revealed that two-year institutions provide education for approximately half of the nation's undergraduate students (Wiessner, 2008). However, when it comes to benefiting from dollars that are raised from donors for postsecondary schools,…

Purpose: This paper seeks to analyse the effectiveness and impact of how Google currently trains its new software engineers ("Nooglers") to become productive in the software engineering community. The research focuses on the institutions and support for practice-based learning and cognitive apprenticeship in the Google environment.…

By incorporating two theoretical frameworks this study examines how school characteristics shape first-grade reading ability-grouping practices, and how this, in turn, affects students' reading achievement. The author uses the data from the Early Childhood Longitudinal Study and applies the propensity-score method to examine whether first-grade…

The study explores factors that enhance or inhibit the language adjustment of international students in the U.S. Using social network influence model, the study examines the effects of language resources, language norm, and technology use on international students' self-confidence in overall English skills and four subskills, namely, listening,…
