As well as knowledge structures can be complex and coherent, they might be small and disconnected. This study focuses on knowledge elements of pre-service teachers using diSessa's phenomenological primitives (p-prims) framework. Based on group interviews, a test was developed regarding the knowledge fragments used for explaining free fall in three…

We have investigated the temporal patterns of algebra (N = 606) and calculus (N = 507) introductory physics students practicing multiple basic physics topics several times throughout the semester using an online mastery homework application called science, technology, engineering, and mathematics (STEM) fluency aimed at improving basic physics…

Agentic engagement, or attempts to proactively influence instruction, predicts positive classroom climate and students' motivation. As such, it is a potentially effective target for intervention, though causal evidence is limited. This investigation explored whether an agentic orientation could be cultivated through a brief, online intervention…

A poorly elaborated learner's understanding of models has been reported to be one of the major sources for learning difficulties in the quantum domain. To be able to provide physics education in schools with evidence as to how this problem can be tackled, a deeper theoretical understanding of the structure of learners' mental models in quantum…
