This study explored the extent to which the reading-to-write construct is the sum of one's reading and writing abilities or an independent construct. The investigation included an analysis of (a) test tasks, (b) the relationship of test task scores and scores on reading and writing measures, and (c) the effects of proficiency level and educational…

Objective: The primary objective of the study was to investigate the relationship between exposure to community violence (neighborhood, school, police, and gang violence) and psychological distress in a sample of children living in the Cape Town, South Africa area. Another objective was to identify variables that moderate and mediate the…

A sample of 523 Chinese university students was given a questionnaire on their attitudes towards the inclusion of children with disabilities into regular classrooms. Factor analysis, analysis of variance, t-test and correlations were used to assess the respondents' general attitude towards inclusion, the factor structure of the attitudes, the…

This article builds on research related to the perceptions, perspectives, and experiences of educators in relation to democracy in education (Carr, 2006a), which, it is argued, can be viewed as having a significant impact on what students in elementary and secondary schools learn about democracy (McLaren, 2007; Regenspan, 2002), and, importantly,…

This study assessed the importance of teacher preference of individual students, relative to peer rejection and student aggression, as an independent predictor of children's emotional adjustment and grades. First, a longitudinal, cross-lagged path analysis was conducted to determine the patterns of influence among teacher preference, peer…

This study investigated the relationship between intercultural perceptions, identity, and academic achievement among African American males. Specifically, this study investigated the relationship of academic achievement, cultural mistrust, oppositional cultural attitudes, ethnic identity development and educational outcome expectations and value,…

This article addresses two inconsistent findings in the literature on adolescent religious activity (RA) and substance use: whether a dose-response relationship characterizes the association of these variables, and whether the association varies by grade, gender, ethnicity, family structure, school type, and type of substance. Multinomial logistic…

The main goal of this study was to assess how sensitive unidimensional parameter estimates derived from BILOG were when the unidimensionality assumption was violated and the underlying ability distribution was not multivariate normal. A multidimensional three-parameter logistic distribution that was a straightforward generalization of the…

A method of estimating Rasch-model difficulty calibrations from judges' ratings of item difficulty is described. The ability of judges to estimate item difficulty was assessed by correlating estimated and empirical calibrations on each of four examinations offered by the American Association of State Social Work Boards. Thirteen members of the…

Issues and problems in assessment research are explored, with suggestions to help establish an acceptable correlation between student assessment scores and final grades. Topics include assessing instructor grading variation, instructor grade point average (GPA), success rates, and lack of linearity in grade scales. Solutions to these problems are…

The Kaufman Brief Intelligence Test (K-BIT) was used as a screening instrument to predict Wechsler Intelligence Scale for Children-Third Edition (WISC-III) scores of 94 students referred for psychoeducational evaluations. Although the correlation coefficient between the K-BIT IQ Composite and the WISC-III Full Scale IQ was 0.771 for the entire…

Since canonical correlation analysis subsumes multiple regression as a special case, and since commonality analysis (a variance partitioning procedure) has proven useful in interpreting multiple regression results, the interpretation of canonical correlation results might also be enhanced by the use of commonality analysis. In this paper, a…

Even though Swedish students (age 9 and 14 years) placed third in the recent IEA study, reading instruction in Swedish schools is apparently no better than in other countries taking part in the IEA study. No strong correlations between type of reading instruction and students' reading skills have been found. Schools in Nordic countries work under…

The power of the procedure of W. Stout to detect deviations from essential unidimensionality in two-dimensional data was investigated for minor, moderate, and large deviations from unidimensionality using criteria for deviations from unidimensionality based on prior research. Test lengths of 20 and 40 items and sample sizes of 700 and 1,500 were…

The need for using invariance procedures to establish the external validity or generalizability of statistical results has been well documented. Invariance analysis is a tool that can be used to establish confidence in the replicability of research findings. Several approaches to invariance analysis are available that are broadly applicable across…
