Course-based undergraduate research experiences (CUREs) have been identified as a promising approach to engage large numbers of students in discovery-based investigations in the biological sciences. As the prevalence of CUREs continues to increase nationwide, the role of graduate teaching assistants (TAs) in facilitating these courses has…

Proton nuclear magnetic resonance ([superscript 1]H NMR) spectroscopy is an essential characterization tool for organic chemists widely taught in the undergraduate chemistry curricula. Previous work has focused on how students advance from novice to expert in interpreting [superscript 1]H NMR spectra. However, we need to know more about how…

Formative assessment is highly beneficial for student motivation and achievement, but in undergraduate courses, especially large introductory life sciences courses, it may be difficult for instructors to gather the evidence necessary for quality formative assessment. Undergraduate teaching and learning assistants (UTLAs) can help to implement…

Graduate education in chemistry typically follows an apprenticeship model, primarily aimed at preparing students for academia; however, the inclusion of teaching within this apprenticeship is not always clear as faculty, students, and other stakeholders do not agree on the need for instructional training. Despite the variability in training, a…

Graduate teaching assistants (GTAs) are an integral part of the instructional personnel in undergraduate general chemistry courses. Professional development programs for GTAs are well-established across STEM disciplines ranging from two-day to week-long sessions, covering a wide variety of topics, ranging from pedagogy and safety standards to…

Acid-base chemistry is a foundational concept for organic chemistry, and the complexities in teaching and learning acid-base chemistry are well documented. This study aimed to investigate post-secondary instructors' pedagogical content knowledge (PCK) for teaching acid-base chemistry in an organic chemistry context. Two groups of three graduate…

Teaching assistants have a very important role in physics education as they interact with students and guide them in different contexts. A multitude of research has focused on how to prepare teaching assistants to implement high-quality, research-based teaching techniques. Video clubs, i.e., working with a group of teachers to watch and discuss…

Undergraduate laboratory courses can provide opportunities for students to participate in science practices. This requires rethinking both curricula and instruction. Science practice--based courses require students to be positioned as epistemic agents, implying a shift in instructor role. Teaching assistants (TAs) are the primary instructors for…

Given the potential impact of introductory science laboratories on postsecondary students' science learning, careful thinking is needed about how to support teaching assistants (TAs) to create opportunities for their students to reason about science. Research suggests that teachers are best positioned to improve their teaching practices when they…

A course centered around transition-metal catalysis in modern drug discovery was designed to illustrate the central role of organic chemistry in driving small-molecule drug development. The course highlighted both fundamental and applied concepts, first with a focus on the drug discovery process, followed by foundational principles in catalysis…

Graduate teaching assistants (GTAs) are important partners in practical chemistry teaching and learning, but they rarely receive direct instruction in inclusive teaching practices and equality, diversity, and inclusion principles. Here we describe the design, delivery, and evaluation of a workshop, along with the resources developed, to support…

Physics graduate teaching assistants (GTAs) are tasked with multifaceted teaching assignments, such as leading tutorials and inquiry-based laboratories, yet their professional development rarely includes opportunities to rehearse complex pedagogical skills or receive feedback on their teaching. In this study, physics GTAs practiced specific…

In this action research study, I propose a guided inquiry alternative to the traditional physical chemistry laboratory module where the equilibrium constant of acetic acid is determined conductometrically. I complement the guided inquiry structure with a 360° feedback support framework for the preparation and assessment of a laboratory report. The…

Due to the COVID-19 pandemic, Biology Teaching Assistants (TAs) were tasked with transitioning and adapting their instruction to an online environment by quickly implementing Emergency Remote Teaching (ERT) practices. Effective online and in-person teaching requires student-centered approaches to support undergraduate student learning. Using…

This concurrent triangulation mixed method design study describes the influence of a science education seminar (SES) on the learning assistants' (LAs) perceptions of their roles in the classroom. The SES was developed to train undergraduate students as LAs at a Southern liberal arts college in the USA. The focus of the seminar was teaching the LAs…
