Undergraduate general chemistry courses are often perceived in a negative light by students. Student attitudes towards chemistry play a significant role in their success in chemistry and retention in STEM altogether. Research has shown in K-12 classrooms that care-based instruction strategies can help to improve student attitudes towards…

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 study explores the relationship between seating quadrants and student performance, including the role of classroom type in the quadrant effect. Data collected from 131 classes taught at 17 colleges of Northwest A&F University in China were analyzed using the ordinary least squares method. The results revealed that where a student sat in a…

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…

This paper introduces a process of reading, reflection, and discussion used by two white faculty teaching at predominately white institutions to address challenges to equity in their introductory astronomy courses. The conversations focused on the context of large introductory courses, where individual instructors may lack resources and agency to…

Background: Fear of negative evaluation, defined as a sense of dread associated with being unfavorably evaluated in a social situation, is the primary factor underlying student anxiety in college science courses and is disproportionately experienced by students who are underserved in science. Yet, it is unknown why fear of negative evaluation…

Background: The role of career interventions and their impact on students' sense of self and preparation for careers in STEM fields is an underexplored teaching and research area within STEM education. Purpose: The purpose of our mixed-methods study was to examine how a life sciences career exploration course at a large public research university…

While the number of students with disabilities in postsecondary programs has increased over the past few decades, they earn lower grades and are less likely to graduate. Academic outcomes are also worse for those with invisible disabilities such as ADHD and learning disabilities, especially as younger college students. Large, intro level courses…

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…

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 rise of technology and online approaches has challenged the traditional learning and teaching model for first year chemistry of formal face-to-face lectures and in-person laboratory sessions. The COVID-19 pandemic since 2020 has created a rapidly changing environment in assessment and learning experiences for students and led to rapid adoption…
