Enrollment in high school physics across the United States of America is notably lower than in other scientific disciplines. Given that physics serves as a prerequisite for admission into many STEM (Science, Technology, Engineering and Mathematics) degree programs, the lack of completion of this course at the high school level can significantly…

This study investigated the effects of Discovery Learning Scientific Community Laboratories (DL-SCL) and traditional non-DLSCL laboratories on students' conceptual understanding in a Physics-1 lab. At many universities, physics programs use a traditional lab style, despite research on the benefits for reform-oriented physics labs. This DL-SCL…

Education research has repeatedly shown that active learning in physics is pedagogically more efficient than traditional lecture courses. Widespread application of the active learning is slowed down by the lack of data on the performance of the active learning in widely varying circumstances of different educational systems. We measured the level…

Peer Instruction, a pedagogy utilizing handheld classroom response technology to promote student discussion, is one of the most popular research-based instructional practices in STEM education. Yet, few studies have shed theoretical light on how and why Peer Instruction is effective. In this article, J. Bryan Henderson explores the Peer…

Over the course of instruction, not only does most introductory physics students' content knowledge evolve but their attitudes and approaches to problem solving are also likely to evolve. This change may depend on many factors including the curricula and pedagogies used, the degree to which instruction actively engages students in the learning…

This thesis explores impact of evidence-based active-engagement courses (EBAE) on student achievement and gender gap in introductory physics. The first study is about the pedagogical content knowledge (PCK) of the physics teaching assistants (TAs) at identifying introductory students' difficulties using the Conceptual Survey of Electricity and…
