Simulations were conducted to establish best practice in hyperparameter optimization and accounting for clustering in Generalized Linear Mixed-Effects Model Trees (GLMM trees). Using data-driven best practices, the relationship between a 9th Grade On-Track to Graduate (9G-OTG) indicator and observed high school graduation within four years was…

Emergent technologies present platforms for educational researchers to conduct randomized controlled trials (RCTs) and collect rich data on study students' performance, behavior, learning processes, and outcomes in authentic learning environments. As educational research increasingly uses methods and data collection from such platforms, it is…

This study presents part of a research project currently underway which aims to characterise the best practices of highly effective schools in the Autonomous Region of the Basque Country (Spain). Multilevel statistical modelling and hierarchical linear models were used to select 32 highly effective schools, with highly effective being taken to…

Teachers are key players in efforts to address school bullying and peer victimization. Recent studies found that teachers' responses to peer victimization can vary based on their beliefs and attitudes. We examined relations among teacher self-efficacy, teachers' intentions to use recommended antibullying practices, and peer victimization as rated…

This paper forms part of a research project that aims to characterise best practices in highly effective schools in the Autonomous Region of the Basque Country (ARBC). The aim is for the best practices identified to serve as points of reference when designing improvement plans to be implemented in all schools in the ARBC, with the advice and…

This Methodological Brief gives an overview of statistical methods used to gauge academic growth and discusses issues surrounding the measurement of growth in gifted populations. To illustrate some of these issues, we describe a growth model that examines differences in summer lag between gifted and nongifted students. We also provide…

The Standards for Effective Pedagogy and Learning (CREDE, 2014) specify five "transnational universals of teaching" that are especially effective for the rapidly growing population of English language learners in North America. CLASSIC is an evidence-based, CREDE-aligned model of teacher education for classroom educators of English…

The education of doctoral chemists contributes to the chemical research enterprise and thus to innovation as an engine of the economy. This quantitative analysis describes trends in the production and diversity of chemistry Ph.D. degrees in the top-50 U.S. Ph.D.-granting departments in the past two decades. Time series data for individual…

Colleges and universities are being pressed to seek innovative ways to measure student learning outcomes and identify the conditions that lead to their development. Understanding how students group according to a multidimensional set of learning outcomes provides information on the extent to which institutions are meeting goals. This study…
