Multiple imputation (MI), a two-stage process whereby missing data are imputed multiple times and the resulting estimates of the parameter(s) of interest are combined across the completed datasets, is becoming increasingly popular for handling missing data. However, MI can result in biased inference if not carried out appropriately or if the…

Learning implies change. Inside and outside schools, we aim for students to change into people with more skills and knowledge as well as with a growing sense of agency and responsibility. Furthermore, education itself is subject to constant change. In this article, we examine change in 3 case studies in the context of individual music lessons from…

Context: Changes in commitment and the predictors of commitment to an athletic training program (ATP) across the academic 4-year program is important for facilitating students' continued success in ATPs and on the Board of Certification (BOC) exam. Objective: The purpose of this study was 2-fold: (1) examine changes in 1 cohort's perceptions of…

Missing data is endemic in much educational research. However, practices such as step-wise regression common in the educational research literature have been shown to be dangerous when significant data are missing, and multiple imputation (MI) is generally recommended by statisticians. In this paper, we provide a review of these advances and their…

This longitudinal case study investigated how one School of Education (SOE), situated in an urban, commuter, public university, responded to the New York State mandate to require the edTPA for initial teacher certification. In order to engage faculty in the work of program redesign, SOE administrators employed a covert leadership approach. Based…

Objective: Colleges have increased postsecondary educational access for youth, including individuals with disabilities, but completion rates remain low. This study tests the hypothesis that health conditions that reduce social integration predict lower educational attainment among college students. Method: The sample from the nationally…

In research on parental involvement and teacher professionalization, counseling parents on the support of their children's learning processes is considered to be an increasingly important competence area of teachers. However, to date little research has been conducted on the development of appropriate approaches to the assessment of teachers'…

The purpose of this project is to demonstrate the practical methods developed to utilize a dataset consisting of both multivariate and multilevel effect size data. The context for this project is a large-scale meta-analytic review of the predictors of academic achievement. This project is guided by three primary research questions: (1) How do we…

This article investigates downgrading from the highest level of secondary education in The Netherlands. "Downgrading" is defined as continuation of secondary education at a lower level. We conduct a longitudinal case study of downgrading in the first 3 years of a secondary school. Univariate and multivariate statistical analyses are…

A large body of research suggests that child maltreatment (CM) is associated with adolescent suicidal ideation and attempts. These studies, however, have not been critically examined and summarized in a manner that allows us to draw firm conclusions and make recommendations for future research and clinical work in this area. In this review, we…

There is broad international agreement about the importance of increasing participation in science once it is no longer compulsory in school, particularly among groups who have been historically underrepresented in science. Previous research reflects that despite broadly positive attitudes to science in and outside of school, there is limited…

Previous research on sensation seeking (SS) was dominated by a variable-oriented approach indicating that SS level has a linear relation with a host of problem behaviors. Our aim was to provide a person-oriented methodology--a probabilistic clustering--that enables examination of both inter- and intra-individual differences in not only the level,…

There is little research in the developing countries of South East Asia on the effectiveness of bilingual education programmes that use first language instruction for ethnic minority children. This study investigated the effectiveness of a bilingual education programme involving ethnic minority children in Cambodia by comparing their performance…

Salthouse (2011) critically reviewed cross-sectional and longitudinal relations among adult age, brain structure, and cognition (ABC) and identified problems in interpretation of the extant literature. His review, however, missed several important points. First, there is enough disparity among the measures of brain structure and cognitive…

Background: School district wellness policies designed to reduce obesity and promote student health and well-being often lack specific requirements or any mandate that schools comply with the policy. Researchers, educators, and policymakers have called for states to take an active role in shaping district policies. The objective of this study was…
