The purpose of this study was to determine the effects of an early numeracy preventative Tier 2 intervention on the mathematics performance of first-grade students with mathematics difficulties. Researchers used a pretest-posttest control group design with randomized assignment of 139 students to the Tier 2 treatment condition and 65 students to…

The authors examine the impact of a program designed to encourage students to read popular business magazines. The results suggest that a reading program can improve student knowledge of current events, but that more work is needed to encourage students to attain timely knowledge of the current environment of business.

A decline in social engagement has a negative impact on numerous elements considered critical for successful aging. Because many social and productive activities require effective communication skills for individuals to remain fully engaged, it was hypothesized that self-perceived hearing problems limit the frequency of engagement in social and…

The Investigators hypothesized cooperating teachers' evaluations of candidates in clinical practice and field experiences would possess higher scores than those provided by clinical and education division faculty. However, the reasons for the higher scores proved to be much more complex than originally thought. While it was assumed that teachers…

Researchers have found a strong relationship between improvements in quality and satisfaction, revenue, and cost. However, no study to date investigates the same for higher education. This study investigates whether institutions of higher education have implemented quality improvement programs, and if so, if the results are similar to what has…

Controversy surrounding the use of race-conscious admissions can be partially resolved with improved empirical knowledge of the effects of racial diversity in educational settings. We use a national sample of law students nested in 64 law schools to test the complex and largely untested theory regarding the effects of educational diversity on…

Many undergraduate institutions offer individual research opportunities for upper-level students in independent study courses and summer undergraduate research programs. These are necessarily limited to a small number of students. Greater numbers of students can benefit from incorporating student-directed investigative experiences into…

Nonprofit child care centers are frequently observed to produce child care which is, on average, of higher quality than care provided in commercial child care centers. In part, this nonprofit advantage is due to different input choices made by nonprofit centers--lower child--staff ratios, better-educated staff and directors, higher rates of…

This study examines the acquisition of the English laryngeal system by native speakers of (Belgian) Dutch. Both languages have a two-way laryngeal system, but while Dutch contrasts prevoiced with short-lag stops, English has a contrast between short-lag and long-lag stops. The primary aim of the article is to test two hypotheses on the acquisition…

Early-onset schizophrenia appears to be clinically more severe than the adult-onset form of the disease. In a previous study, we showed that anatomically related grey and white matter abnormalities found in adolescents patients were larger and more widespread than what had been reported in the literature on adult schizophrenia. Particularly, we…

This study was designed as a confirmatory study of work on "productive failure" (Kapur, "Cognition and Instruction," 26(3), 379-424, 2008). N = 177, 11th-grade science students were randomly assigned to solve either well- or ill-structured problems in a computer-supported collaborative learning (CSCL) environment without the provision of any…

Background: Standardised neuropsychological and cognitive measures present some limitations in their applicability and generalisability to individuals with intellectual disability (ID). Alternative approaches to defining the cognitive signatures of various forms of ID are needed to advance our understanding of the profiles of strengths and…

A technique for selecting alpha based on the particular circumstances of a hypothesis testing problem is illustrated. In selecting an alpha, the technique takes into account the prior probability that the null hypothesis is true and the penalties associated with Type I and Type II errors. (Author)

A Fortran Extended program which computes Goodman and Kruskal's Tau-b, its asymmetrical counterpart, Tau-a, and three sets of confidence limits for each coefficient under full multinomial and proportional stratified sampling is presented. A correction of an error in the calculation of the large sample standard error of Tau-b is discussed.…

A large class of rank tests which includes the "sign test" and Wilcoxon signed-ranks test is described. These distribution free tests provide a basis for testing various research hypotheses. Exact small sample and approximate large sample procedures are considered. Applications are presented including numerical examples. (Author/HG)
