In a partially flipped, hybrid introductory physics course where students had a free choice between attending any lecture session in person or via video conferencing, and where recordings of the lecture sessions were made available for asynchronous viewing, a total of 16 learner attributes and their relationships were investigated. Five of these…

When teaching a general education introductory astronomy course that includes a mathematics prerequisite, it is important to convey that formulas and equations physically represent properties of actual objects and processes that occur that can actually be observed. Students with varying comfort levels with mathematics often need to be convinced…

The Energy and Momentum Conceptual Survey (EMCS) is a multiple-choice survey that contains conceptual problems involving a variety of energy and momentum concepts covered in a typical introductory physics course for science and engineering majors. Prior studies suggest that many concepts on the survey are challenging for introductory physics…

Background: Active learning used in science, technology, engineering, and mathematics (STEM) courses has been shown to improve student outcomes. Nevertheless, traditional lecture-orientated approaches endure in these courses. The implementation of teaching practices is a result of many interrelated factors including disciplinary norms, classroom…

We show how learning can be improved, beyond that shown in actively taught classrooms, by also transforming the homework using the principles of deliberate practice. We measure the impact of transforming the homework on student learning in a course that had already implemented an active approach to teaching in class. We compare performance on the…

Introductory mechanics is an obligatory course for many disciplines outside of physics and the failure rate is often high. Even the students who pass the course often fail to achieve the main learning goal: The conceptual knowledge required for modeling situations with physics principles. In many cases, this is due to inefficient learning…

At large institutions of higher education, students frequently have a choice whether to attend the introductory physics sequence asynchronously online, on-site in a traditional lecture setting, or in a reformed studio setting. In this study, we investigate how these different settings are correlated with measures of self-efficacy, interest in…

This study examines high school preparation measures [ACT/SAT scores, high school grade point average (HSGPA), and conceptual physics pretest scores], in-class behavior measures (homework submission rates and lecture attendance rates), and in-class achievement measures (homework and test averages) for the last two fully face-to-face prepandemic…

The effect of class size on student learning has numerous policy implications and has been a major subject of conversation and research for decades. Despite this, few studies have been done on class size in the context of university settings or physics courses. This dissertation helps address that gap in the literature by quantitatively analyzing…

Introductory physics for life sciences (IPLS) courses have emerged as a type of physics course within the introductory courses sequence. The interdisciplinary aspects of these courses as well as the diverse student populations that they serve create significant challenges for instructors who choose to design and deliver them. The Living Physics…

It has been well-establishing in the field of educational research that traditional educational methods such as passive lectures and labs where students follow pre-designed procedures to verify information already told to them are not effective for promoting meaningful and lasting conceptual understanding. Alongside this knowledge have come a…

Although active learning is supported by strong evidence of efficacy in undergraduate science instruction, institutions of higher education have yet to embrace comprehensive change. Costs of transforming instruction are regularly cited as a key factor in not adopting active-learning instructional practices. Some cite that alternative methods to…

Researchers have pinpointed recognition from others as one of the most important dimensions of students' science and engineering identity. Studies, however, have found gender biases in students' recognition of their peers, with inconsistent patterns across introductory science and engineering courses. Toward finding the source of this variation,…

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…

Undergraduate students benefit from academic-centered peer interactions, especially in large lecture courses. However, little is known about how students come together and form relationships around a course. I conduct a mixed-methods study of students' peer networks to explore how students choose peers for academic-focused interactions. The…
