At the onset of the COVID-19 pandemic, our teacher preparation program shifted to an online setting, disrupting a key feature of practice-based teacher preparation: preservice science teachers' (PSTs) approximation of rigorous and responsive instruction during extended pedagogical rehearsals, called macroteaching. Given this unplanned shock to…

The Math Curriculum Impact Study was a large-scale randomized controlled trial (RCT) to test the efficacy of a digital core curriculum for Grade 5 mathematics. Reasoning Mind's Grade 5 Common Core Curriculum was a comprehensive, adaptive, blended learning approach that schools in the treatment group implemented for an entire school year. Schools…

Scientific progress is built on research that is reliable, accurate, and verifiable. The methods and evidentiary reasoning that underlie scientific claims must be available for scrutiny. Like other fields, the education sciences suffer from problems such as failure to replicate, validity and generalization issues, publication bias, and high costs…

Massive open online courses (MOOCs) are marketed as opportunities for participants to improve their labor market outcomes, and tens of thousands of students have paid for career-focused MOOC certificate programs. However, there is limited and conflicting research on MOOCs and labor market outcomes. Using two randomized control trials, we test…

In spring 2020, COVID-19 seismically shifted the education landscape as schooling moved online. We report a small-scale mixed-methods study of how that upheaval affected three-dimensional science learning in elementary school classrooms, and how the situation changed when school resumed, in modified form, in fall 2020. Teachers with experience in…

We searched and meta-analyzed studies comparing flipped classroom teaching with traditional, lecture-based teaching to evaluate the evidence for the flipped classroom's influence on continuous-learning measures, pass/fail rates, and student evaluations of teaching. Eight electronic reference databases were searched to retrieve relevant studies.…

This study examines the Association of American Universities Undergraduate STEM (science, technology, engineering, and mathematics) initiative and the ability of a national organization and its member institutions to reshape norms about the importance and value of teaching and dedicated efforts to teaching improvement. The study is framed with…
