Effective active learning supports student engagement in generative learning behaviors, often through collaborative group work. Although collaborative learning has many benefits, it can be difficult for individual instructors to prompt knowledge building discourse in large enrollment courses. Peer Learning Assistants (PLAs) can provide the…

While zinc (Zn[superscript 2+]) is a vital ion for cell function and human health, we are still learning about how Zn[superscript 2+] concentration and localization is regulated and the role that Zn[superscript 2+] fluctuations may play in regulating cell signaling and cell fate. Here, we use fluorescent tools to study the interaction between…

Although many undergraduates begin college as STEM majors, attrition rates from the field are high and numerous reports suggest that evidence-based teaching methods are critical for retention. Despite educators' research and near consensus that active learning is more effective than lecture, there are many types of active learning and the…

Nearly half of all U.S. students who declare science majors in college do not graduate with science degrees within six years. Improvements in science outcomes are linked with active-learning pedagogies such as Course-based Undergraduate Research Experiences (CUREs). However, despite the need for education reform particularly in Alabama,…

This study investigates how students can use "interactive example models" in inquiry activities to develop their conceptual knowledge about an engineering phenomenon like electromagnetic fields and waves. An interactive model, for example a computational model, could be used to develop and teach principles of dynamic complex systems, and…

This three-paper dissertation addresses the experience and the implementation of evidence-based learning practices in science, technology, engineering, and mathematics (STEM)/biology education. Study 1 explored instructional strategies and student perceptions and preferences for various teaching practices in graduate and undergraduate classrooms…

Participation in the science workforce is low, and this can be partially attributed to low retention rates of undergraduate students who initially declare a science major. Low retention rates are further exacerbated for under-represented minority (URM) and first-generation (FG) college students pursuing science, and the existence of achievement…

This study is composed of several projects in the field of physics education research. First, investigations into flipped physics classrooms at the senior and graduate level show that students uniformly agree that the active learning techniques (peer instruction, group problem solving, etc.) were beneficial to their learning regardless of their…

This thesis explores impact of evidence-based active-engagement courses (EBAE) on student achievement and gender gap in introductory physics. The first study is about the pedagogical content knowledge (PCK) of the physics teaching assistants (TAs) at identifying introductory students' difficulties using the Conceptual Survey of Electricity and…

Active learning, an engaging, student-centered, evidence-based pedagogy, has been shown to improve student satisfaction, engagement, and achievement in college classrooms. There have been numerous calls to reform teaching practices, especially in science, technology, engineering, and math (STEM); however, the utilization of active learning is…

The purpose of this study was to understand the factors that support the adoption of active learning teaching strategies in undergraduate courses by faculty members, specifically in the STEM disciplines related to geoscience. The focus of the study centered on the context of the department which was identified as a gap in evaluation and…

The United States of America needs STEM trained workers, STEM faculty and STEM professionals to improve its technical and professional workforce in order to maintain leadership in a global economy. However, American students are not opting to remain in a STEM course of study, and this is especially so for women and minorities. Of the students who…

This study investigated the design, enactment, and impact of an undergraduate, inquiry-based astronomy laboratory learning environment. The professor, Richard, adopted laboratory materials from the Center for Astronomy and Physics Education Research [CAPER] which were described by the group as inquiry-based. Students worked through these…

Engaging students in classroom discourse offers opportunities for students to participate in the construction of joint understandings, to negotiate relationships between different types of evidence, and to practice making evidence-based claims about science content. However, close attention to social aspects of learning is critical to creating…

In response to the declining number of students in the United States entering into the STEM (science, technology, engineering, and math) disciplines, there has been an attempt to retain student interest in the sciences through the implementation of more active learning in the classroom. Active learning is defined as any instructional method that…
