Organic Chemistry is considered by many to be the quintessential "weeder course", widely identified in the premed and STEM persistence literature as a gatekeeper to students interested in STEM or health fields (Barr, Gonzalez, & Wanat, 2008; Lovecchio & Dundes, 2002). There has therefore been considerable interest in determining…

Hackathons, the time-bound collaborative project-based competitions increasingly popular with undergraduate CS students, are both transformative and problematic. On one hand, they are unique opportunities to apply skills learned in the classroom to real-world, interest driven projects that celebrate risk taking, collaboration, and playfulness. On…

The purpose of this three study dissertation is to investigate why students are enrolled in introductory physics courses experience difficulties in being successful; one possible source of their difficulties is related to their epistemology. In order to investigate students' epistemologies about mathematics and physics, students were observed…

Serving approximately 80% of the one million college students taking pre-college-level mathematics classes, community colleges perform an important function in providing access to advanced coursework and degrees. Low success rates in these classes has led mathematics educators to consider alternative forms of curriculum and instruction for these…

Mathematics classrooms have reflected little change over the past century, consisting of the learning of inert, disjoint procedures with few connections between mathematics concepts and students' everyday experiences. However, problem posing, that is, the reformatting of existing problems and the generation of new ones, has been promoted by the…

An implicit assumption of many university classes is that students will spend a large amount of time outside the classroom refining their understanding of the material to develop mastery of the concepts. This is especially true in first year mathematics courses at the undergraduate level. However, little is known about what students do to fulfill…
