Despite national curricula and instructional reforms calling for collaborative problem-solving skills (CPS), however, there is an absence of a theory-laden model showing how to effectively construct CPS for science learning. We therefore developed and validated a simulation-based CPS model that exploits its constructs, sequences, and causal…

Artificial intelligence (AI) has transformative potential to support the education of students with moderate to severe intellectual disabilities (M/SID) and their teachers. Although research and evidence-based practices (EBPs) are integral to fostering positive student learning outcomes, educators face challenges in effectively implementing these…

In this study, we described a curricular module on computational thinking (CT) integrated within an undergraduate, senior level elementary science methods course, and developed insights on elementary preservice science teachers' (PSTs) thoughts, feelings, and actions about CT integration. Our research question was: "Following participation in…

Background: Most studies of teacher professional development (PD) do not rigorously test impact on teaching practice and student learning. This makes it difficult to define what is truly "effective." The "Science Teachers Learning from Lesson Analysis" (STeLLA) PD program, in contrast, was studied in a cluster randomized…
