Recent evidence for the effectiveness of active learning interventions has led educators to advocate for widespread adoption of active learning in undergraduate science, technology, engineering, and mathematics courses. Active learning interventions implement technology and collaboration to engage students actively with the content. Yet, it is…

This classroom-based investigation sought to document how, in real time, STEM teachers and students attempt to locate the invariant mathematical relations that are threaded through the range of activities and representations in these classes, and how highlighting this common thread influences student participation and learning. The authors…

A web-based activity and testing system (WATS) has features such as adaptive problem sets, videos, and data-driven tools for instructors to monitor and scaffold student learning. Central to WATS adoption and use are questions about the implementation process: What constitutes "good" implementation and how far from "good" is…

A variety of computerized interactive learning platforms exist. Most include instructional supports in the form of problem sets. Feedback to users ranges from a single word like "Correct!" to offers of hints and partially to fully worked examples. Behind-the-scenes design of such systems varies as well --from static dictionaries of…

The purpose of this study is to describe and examine the structures and policies a public, comprehensive high school put in place to implement problem-based learning (PBL) across content areas. Starting in 2010, the school implemented PBL in the hopes of increasing students' career and college readiness skills. The research took place at a…

Current clinical diagnosis of Autism Spectrum Disorders (ASD) occurs between 3 and 4 years of age, but increasing evidence indicates that intervention begun earlier may improve outcomes. Using secondary analysis of the Early Childhood Longitudinal Study-Birth Cohort data set, the current study identifies early predictors prior to the diagnosis of…
