The study investigates measurement properties of the reading assessment tasks used in the IEA 1991 Reading Literacy (RL) study and the Progress in International Readings Study (PIRLS) 2001 study. The analysis is based on data from the Swedish PIRLS study, comprising 16,676 students in grades 3 and 4. As an extension to the basic design, not only…

The pattern of parent-child correlations in adoption studies has long been interpreted to suggest substantial additive genetic variance underlying variance in IQ. The studies have frequently been criticized on methodological grounds, but those criticisms have not reflected recent perspectives in genetics and developmental theory. Here we apply…

This study was designed to examine the relationship between conceptions of ability and understandings of the meaning of effort. Participants practiced a novel task and completed an ability conceptions questionnaire prior to instruction and a meaning of effort survey after practicing the task. The majority of participants believed in the efficacy…

115 Italian and French teachers of high school and junior high school participated in a study aimed at investigating the impact of causal attribution on judgments of responsibility in case of academic failure of their pupils. Results support the attribution theory as conceptualized by Weiner (1986, 1995) and confirm the predictive utility of the…

Academic self-concept and academic interest are crucial concepts for understanding students' academic achievement. Yet, few questionnaires currently exist that have been used and validated in more than one country. This study aimed at assessing these concepts using an academic self-concept questionnaire (Marsh, 1990) and an academic interest…

The present study utilized both the IRT-LR (item response theory likelihood ratio) and a series of CFA (confirmatory factor analysis) multi-sample analyses to systematically examine the relationships between DIF (differential item functioning) and DTF (differential test functioning) with a random sample of 15 000 Korean examinees. Specifically,…

Background: This study seeks to identify the cornerstones of personal bests (PBs) in the educational setting. Aims: The study proposes a multidimensional PB model in which students are most likely to attain PBs on tasks/goals that are (1) specific, (2) challenging, (3) competitively self-referenced, and (4) self-improvement based. Sample: The…

Purpose: In this paper empirical research is presented that investigates managers' perceptions of a variety of component management skills and techniques. The aim is to identify which management development needs manufacturing SME managers perceive as most important for their continued development, and to consider contextual factors that might…

Using data from Grades 5, 6, and 7 of the 4-H Study of Positive Youth Development (PYD), the role of intentional self-regulation in the positive development of young adolescents was examined through use of the Selection, Optimization, and Compensation (SOC) measure. Consistent with Gestsdóttir and Lerner (2007), results of confirmatory factor…

There are usually many testing activities going on in a school, with different tests serving different purposes, thus organization and planning are key in creating an efficient system in assessing the most important educational objectives. In the ideal case, an assessment system will be able to inform on student learning, instruction and…

Some extant theory and empirical research suggests that youth problem behaviors, such as substance abuse and delinquency, reflect a single underlying dimension of behavior, whereas others suggest there are several different dimensions. Few studies have examined potential international differences in the structure of problem behavior, where…

The "Social-Communication Assessment Tool" (S-CAT) was created as a direct observation instrument to quantify specific social and communication deficits of children with autism spectrum disorders (ASD) within educational settings. In this pilot study, the instrument's content validity and interrater reliability were investigated to determine the…

Whether the presence of bidimensionality has any effect on the adaptive recalibration of test items was studied through live-data simulation of computer adaptive testing (CAT) forms. The source data were examinee responses to the 298 scored multiple choice items of a licensure examination in a health care profession. Three 75-item part-forms,…

A study examined issues related to between- and within-class decomposition of variance in reading achievement. The aim is to find "pure" latent structures of achievement at the between-class level as a basis for further investigation of explanatory factors such as teaching. Multilevel factor analysis (MFA) can give a pattern…

A study examined the organizational climate of a university undergoing dramatic change and its relationship to specific aspects of that institution's organizational culture. Earlier research has shown that organizational climate directly affects an organization's communication climate, but it is less clear how organizational climate influences and…
