This study investigates the effect of a Framework-aligned professional development program at the PreK-3 level. The NSF funded program integrated science with literacy and mathematics learning and provided teacher professional development, along with materials and programming for parents to encourage science investigations and discourse around…

One of the focuses of language revitalisation policies is to incorporate minority languages into education. Evaluation of new language-of-instruction models is usually based on the increase of minority language speakers. However, it is also important from an educational perspective to study the possible relationship between performance and…

This study investigated effect of student- and school-level variables on mathematics achievement of fourth- and eighth-grade students using the Trends in International Mathematics and Science Study (TIMSS) 2011 data of Turkey. The common variables addressed in student and school questionnaires were compared. Due to nested structure of the TIMSS…

The internal/external frame of reference and the big-fish-little-pond effect are two major models of academic self-concept formation which have considerable theoretical and empirical support. Integrating the domain specific and compensatory processes of the internal/external frame of reference model with the big-fish-little-pond effect suggests a…

Research Findings: It is widely acknowledged that consistent, high-quality teacher-student interactions promote optimal developmental outcomes for children. Previous research on the quality of teacher-student interactions provides empirical support for this premise. Little research has been conducted on the consistency of teacher-student…

The purpose of this study was to pilot the Positive Life Changes (PLC) program, a comprehensive cognitive-behavioral intervention for at-risk adolescents that aims to promote social competencies and to prevent aggression. The program was piloted in 4 intervention groups with a sample of 31 self-referred adolescents (M age 15.64) attending an…

The aim of this study was to pilot test a classroom-based intervention focused on facilitating play and joint attention for young children with autism in self-contained special education classrooms. Thirty-three children with autism between the ages of 3 and 6 years participated in the study with their classroom teachers (n = 14). The 14 preschool…

Weiss, Keith, Zhu, and Chen (2013a) and Weiss, Keith, Zhu, and Chen (2013b), this issue, report examinations of the factor structure of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) and Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV), respectively; comparing Wechsler Hierarchical Model (W-HM) and…

The relationship between a superintendent and the school board is a key element in determining the tenure of the superintendent (Barth, 2003; Hoyle, English, & Steffy, 1998; Glass & Franceschini, 2007; Hess, 2002; Mountford, 2008), and superintendent tenure often determines the ability of school districts to make necessary improvements…

This paper extends single-level missing data methods to efficient estimation of a "Q"-level nested hierarchical general linear model given ignorable missing data with a general missing pattern at any of the "Q" levels. The key idea is to reexpress a desired hierarchical model as the joint distribution of all variables including…

Change in learning strategies during higher education is an important topic of research when considering students' approaches to learning. Regarding the statistical techniques used to analyse this change, repeated measures ANOVA is mostly relied upon. Recently, multilevel and multi-indicator latent growth (MILG) analyses have been used as well.…

Background: There is wide variation in language abilities among young children with autism spectrum disorders (ASD), with some toddlers developing age-appropriate language while others remain minimally verbal after age 5. Conflicting findings exist regarding predictors of language outcomes in ASD and various methodological issues limit the…

This multilevel study examined the relationship between school climate and academic achievement. Using the Educational Longitudinal Survey (ELS, 2002), and a sample of 16,258 students and 1954 schools nationwide, we found that student-level perception of school climate--especially the student learning environment--was highly predictive of academic…

Background: Educational processes and outcomes are influenced by a multitude of factors, including individual and contextual characteristics. Recently, studies have demonstrated that student and context characteristics may produce unique and cumulative effects on educational outcomes. Aims: The study aimed to investigate (1) the relative…

The current study applied the person-fit statistic, l[subscript z], to data from a Canadian provincial achievement test to explore the usefulness of conducting person-fit analysis on large-scale assessments. Item parameter estimates were compared before and after the misfitting student responses, as identified by l[subscript z], were removed. The…
