Accuracy on assessments is commonly studied in education research but response time (RT) is relatively less investigated even though decades of research in cognitive sciences indicate that time can be an important dimension for understanding student learning. To better understand RT and the potentially important relations between accuracy and RT…

This study investigated factors influencing Force and Motion Conceptual Evaluation (FMCE) pretest and post-test scores for a sample (N=1116 students) collected in the introductory calculus-based mechanics class at a large eastern land-grant university. Several academic and noncognitive factors were examined using correlation analysis and linear…

Students' motivational beliefs, such as disciplinary intelligence mindsets, can influence their physics performance and persistence. Intelligence mindset beliefs have long been argued to fall along of continuum between fixed and growth mindsets. Those with fixed physics mindsets believe that ability in physics is innate and unchangable, while…

Students' self-efficacy in physics classes can play a key role in shaping course outcomes. Prior research has shown that women have a lower self-efficacy than men in calculus-based introductory physics courses. We administered a validated survey to 564 students to investigate the gender differences in self-efficacy and how it predicts student…

In this study, we investigated female and male students' sense of belonging and their academic performance measured by the Force Concept Inventory (FCI) and course grades in a calculus-based introductory physics course at a large public university in the United States. We find that compared to male students, female students' sense of belonging was…

Student sense of belonging in physics classes may not only play a key role in shaping course outcomes but also influence student persistence and future career aspirations. Prior research has shown that women have a lower sense of belonging than men in calculus-based introductory physics courses. However, prior research has generally not…

This study examined physics major retention to degree at two institutions with substantially different admissions selectivity. Two modes of leaving the physics major were examined: leaving college and changing to another major while staying in college. The risk of leaving college while still enrolled as a physics major was highest in the spring…

An analysis of 1955 physics graduate students from 19 Ph.D. programs shows that undergraduate grade point average predicts graduate grades and Ph.D. completion more effectively than GRE scores. Students' undergraduate GPA (UGPA) and GRE Physics (GRE-P) scores are small but statistically significant predictors of graduate course grades, while GRE…

Diagnostic tests for placing students into appropriate courses are commonly used in higher education math and science departments. We found no physics education research examining the validity of such exams, how well they are placing students into appropriate courses, and what guidance these exams can give for better focusing instruction. In this…

Two set of studies were conducted to better understand grades and grading practices in physics courses, and how these might influence demographic representational disparities in physics. The first study investigates the relationships between grades and the student-level factors of standardized test scores, (binary) gender, underrepresented…
