Mixed results have been reported on the correlation between clickers and performance. This study investigates the usage of clickers in a voluntary context to answer in-class questions in a General Chemistry class. Scores on an internal chemistry placement exam were used to estimate cognitive ability, as a factor that students can no longer…

To transition introductory college science courses from large, passive lectures to more student-centered learning environments, additional instructional support is needed. Peer learning assistants (PLAs) can support that transformation by engaging students in interactive discourse and collaborative learning during class activities. PLAs are…

A comparison of student performance in an introductory biology class that used a lecture-based approach (N = 15 classes; 462 students) with those that had a no-lecture approach (N = 9 classes; 238 students). All classes were taught by the principal researcher. In the no- lecture environment, shifts in student perceptions of science were…

Students need a strong understanding of how to represent chemical compounds in order to succeed in organic chemistry. This project set out to gain a better understanding of students' difficulties with symbolic representations, by identifying the specific errors associated with drawing wedge-dash structures. The focus was on how students…

Active learning is the new standard for teaching in higher education. As more faculty seek to expand their teaching practices by including active-learning activities that promote higher levels of learning, many are doing so in small doses by temporarily postponing traditional lectures in favor of group activities. While there is evidence…

Traditional lab courses separate lectures from lab work, whereas integrated lab-lecture courses (also known as studio courses) combine both in a single session under one instructor. Previous studies suggest that integrated lab-lecture courses may have the potential to enhance the learning experience for introductory-level students. In this…

This study investigates the relationship between study methods and exam performance in introductory physics courses. Data were collected over 3 years through surveys to examine students' study habits, perceived effectiveness of techniques, and the correlation between time allocation and exam grades. Results indicate that high-achieving students…

Moving to remote, online learning to meet health guidelines during the COVID-19 pandemic posed a challenge for college science courses due to the interactive nature of laboratories. We developed and implemented a remote/in-person lab partner model where in-person students were paired with remote students in natural science courses during the…

Quantitative reasoning (QR) competencies are increasingly called for in the data rich and complex environment of STEM disciplines, including biology. Curricular reform efforts in QR have been directed at disseminating course design and pedagogy but less work has been directed at understanding what faculty at large view as crucial for student…

This study is a comparison of ground-based versus online student performance using a combination of common final examination scores and associated demographic data in a biological science college course taught by a single instructor. Multivariate and standard statistical analyses are used to examine data from five semesters of ground and online…

During the pandemic, the use of question pools for online testing was recommended to mitigate cheating, exposing multitudes of science, technology, engineering, and mathematics (STEM) students across the globe to this practice. Yet instructors may be unfamiliar with the ways that seemingly small changes between questions in a pool can expose…

This article describes a quasi-experimental study conducted in two Organic Chemistry I classrooms at a diverse, urban, public university. The treatment group received an exam wrapper intervention, a series of four written exercises administered throughout the semester designed to enhance students' academic self-regulation by promoting…

Gateways-ND is a 5-year, National Science Foundation-funded effort directed toward three goals: maximizing the instructional effectiveness of postsecondary STEM (science, technology, engineering, and mathematics) faculty by building expertise in learner-focused practice, positively impacting student success in STEM-based "gateway"…

This article describes how a Peer-Led Team Learning (PLTL) program was implemented in a first-year, undergraduate Anatomy and Physiology course sequence to examine the student perceptions of the program and determine the effects of PLTL on student performance.

The case study method of teaching uses real-world narratives to teach concepts and content. This method of teaching encourages active learning, which has been shown to have a positive effect on student performance in many disciplines including science. Although more females than males pursue a postsecondary degree, more males than females pursue…
