In a traditional lecturing environment, students possess limited agency in accepting or rejecting information provided by teachers. A higher level of student agency involves opportunities and actively identifying uncertainties and collaborating with peers to deepen understanding within the classroom community. Teachers play a crucial role in…

This study used systematic observation to test the direct and moderating effects of class size on children's momentary behavioural engagement in learning. Data were collected with 632 children (50.6% girls) in 121 classrooms in 92 schools recruited into the Children's School Lives national cohort study of Irish primary schooling. The Observational…

Many large introductory classes are taught in stadium-style classrooms, which makes group work more difficult due to the room layout and immobile seating. These classrooms may create challenges for an instructor who wants to monitor student engagement because the layouts make it difficult to interact with the students as they work. Student…

This study explores the relationship between the self-confidence and content knowledge of undergraduate students in a large enrollment geoscience course following an active-learning think-pair-share (TPS) activity, and whether high confidence necessarily leads to overconfidence. We used a pre-experimental, one group pre-test -- post-test design,…

This article examines the risk of crossover contamination in individual-level randomization, a common concern in experimental research, in the context of a large-enrollment college course. While individual-level randomization is more efficient for assessing program effectiveness, it also increases the potential for control group students to cross…

While uncertainty is inherent to doing science, it is often excluded from science instruction, especially postsecondary chemistry instruction. There are a variety of barriers to infusing uncertainty into the postsecondary chemistry classroom, including ensuring "productive" struggle with uncertainty, evaluating student engagement with…

In education, space exists for a tool that valorizes generic student course evaluation formats by organizing and recapitulating students' views on the pedagogical practices to which they are exposed. Often, student opinions about a course are gathered using a general comment section that does not solicit feedback concerning specific course…

Many conversations surrounding improvement of large-enrollment college science, technology, engineering & mathematics (STEM) courses focus primarily (or solely) on changing instructional practices. By reducing dynamic, complex learning environments to collections of teaching methods, we neglect other meaningful parts of a course ecosystem…

Active learning has often been reported to improve student outcomes in STEM courses. However, there are barriers to its implementation, and it is challenging to include this approach in large classrooms with fixed seating. This investigation explores the development of a novel approach in which the class contact time was reallocated for a general…

Providing students with timely, targeted, and useful feedback regarding their understanding of course topics is generally accepted as a good educational practice. However, when classes are very large there are challenges that prevent many instructors from accomplishing this goal. This study explores the perceived helpfulness to students and the…

Learning assistants (LAs) play an important role in inquiry-oriented physics instruction in large classrooms. LAs increase the teacher-student ratio and provide timely support to student exploration. Questioning is believed to be an advantageous strategy for LAs to scaffold student learning and maintain students as the agent of knowledge…

Introductory science courses can be a struggle for instructors and students not only because of the challenging nature of the material, but also due to differences in the background knowledge of students. Provision of pre-lecture resources reviewing or introducing key concepts is recommended to support diverse students. In this paper, we describe…

The logistics and cost of running large class tutorials to improve learning for students in high enrolment courses raise questions about whether the associated effort and cost are worthwhile. The option to replace these class activities with online homework with its promise of built-in feedback is attractive. Using an activity theory lens and an…

Administering exams in large enrollment courses is challenging and systems in place for accomplishing this task were upended in the spring of 2020 when a sudden transformation to online instruction and testing occurred due to the COVID-19 pandemic. In the following year, when courses remained online, approaches to improve exam security included…

This article aims to explore the experiences of science instructors who are active participants in the design and enactment of an interdisciplinary science course with student-centered pedagogy in a large-enrollment class. The data were collected through interviews with instructors and analyzed using the inductive thematic approach. Results show…
