When exploring missing data techniques in a realistic scenario, the current literature is limited: most studies only consider consequences with data missing on a single variable. This simulation study compares the relative bias of two commonly used missing data techniques when data are missing on more than one variable. Factors varied include type…

The purpose of this study was to determine predictors of community college student academic success in corequisite English and mathematics courses. Academic success was defined dichotomously on a pass or fail basis. The population included 1,934 students enrolled in at least one corequisite English and/or mathematics course at a community college…

This longitudinal study of Mexican-American youth and emerging adults examines several ecodevelopmental factors longitudinally predicting high school and college graduation. Data from 1257 Mexican-American youth (including those born in Mexico and whose families are from Mexico) from the National Longitudinal Study of Adolescent Health (Add…

ASD symptomology and behavioral problems pose challenges for children with ASD in school. Disagreement between parents and teachers in ratings of children's behavior problems may provide clinically relevant information. We examined parent-teacher disagreement on ratings of behavior problems among children with ASD during the fall and spring of the…

Teacher preparation programmes (TPPs) find many ways to shape the development of their teacher candidates while bridging the research to practice gap in university and school partnerships. Recently, accountability models built on high-stakes standardised student assessments (Value-Added Models [VAM]) have been mandated as a way to evaluate the…

The aim of the present study was to investigate the associations between parental and teacher support and elementary students' academic skills during the COVID-19 pandemic. Building on data of an ongoing longitudinal study, we studied the roles of children's (N = 63) academic skills before the first COVID-19 lockdown in Germany (March-June 2020)…

In an effort to increase college access and success rates, the state of Texas has expanded dual enrollment programs and Early College High Schools (ECHS) that provide students with the opportunity to begin their collegiate careers while still in high school. More recently, these dual enrollment and ECHS programs have tried to broaden inclusion…

Growing evidence illustrates the size and character of public-school enrollment declines during the COVID-19 pandemic. However, far less is known about where unenrolled students went. Using unique cross-sector enrollment and mobility data from the state of Hawaii, this study provides evidence that demographic changes and movement to private…

This is a mixed-methods study of risk and resilience in a sample of over 14,000 students from 49 schools, assessed during the first 3 months of COVID-19 in the United States. Over a third of students were of color and almost a third received financial aid. Participation rates were typically 90-99%. Overall, rates of clinically significant…

A wide research base has documented the unequal access to and enrollment in K-12 gifted and talented services and other forms of advanced learning opportunities. This study extends that knowledge base by integrating multiple population-level datasets to better understand correlates of access to and enrollment in gifted and talented services,…

Educational opportunities and resources for students differ around the world. Trends in International Mathematics and Science Study (TIMSS) highlights students' achievement, home resources, and attitudes towards mathematics and science. In this study, we sought to identify home resources and attitudes towards mathematics factors that significantly…

In the present study, we explored how linguistic skills (phonological and semantic) influence the multiple components of school arithmetic (numeration, computation, and word problems) by analyzing them sequentially. We studied a sample of 262 schoolchildren, aged 8 to 11, nested in 27 classrooms, using the following measures: semantic skills,…

Executive functions (EFs) show promise as important mediators of adolescent academic performance. However, the expense of measuring EFs accurately has restricted most field-based research on them to smaller, non-longitudinal studies of homogeneous populations with specific diagnoses. We therefore monitored the development of 259 diverse, at-risk…

Performance prediction is a leading topic in learning analytics research due to its potential to impact all tiers of education. This study proposes a novel predictive modeling method to address the research gaps in existing performance prediction research. The gaps addressed include: the lack of existing research focus on performance prediction…

Attitudes and motivation seem decisive in successful language learning (Dörnyei, Csizér, and Németh 2006. "Motivation, Language Attitudes and Globalisation: A Hungarian Perspective." Clevedon: Multilingual Matters.). Research in Spanish multilingual contexts analysing the influence of the L1 on attitudes and motivation to learn foreign…
