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…

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…

Graduate teaching assistants (GTAs) are key partners in the education of undergraduates. Given the potentially large impact GTAs can have on undergraduate student learning, it is important to provide them with appropriate preparation for teaching. But GTAs are students themselves, and not all of them desire to pursue an academic career. Fully…

Recent reform efforts in postsecondary science teaching have called for shifts in instructional methods to include more evidence-based instructional practices. However, a myriad of factors play a role in whether an instructor adopts these more student-centered methods. One such factor is teaching perspective. In this study, we explored the…

Evaluation of student written work during summative assessments is an important and critical task for instructors at all educational levels. Nevertheless, few research studies exist that provide insights into how different instructors approach this task. Chemistry faculty (FIs) and graduate student instructors (GSIs) regularly engage in the…

Research over the last decade has indicated that active learning and student-centered instruction lead to better learning outcomes in undergraduate biology courses than traditional methods such as lecturing. This shift in pedagogical approach has been applied to both high-enrollment lecture-based courses as well as smaller laboratory courses. In…

We examined physics graduate teaching assistants' views about introductory physics problem "types," i.e., different ways of posing the same underlying physics problem, within the context of a semester-long teaching assistant (TA) professional development course. Here, we focus on TAs' views about two types of broken-into-parts problems…

Formal professional development programs for biology graduate students interested in becoming faculty members have come far; however, programs that provide advanced teaching experience for seasoned graduate teaching assistants are scarce. We outline an advanced program that focuses on further training of graduate teaching assistants in pedagogy…

A new graduate teaching assistant (TA) training program has been developed to support curricular reforms in our large enrollment general chemistry courses. The focus of this training has been to support the TAs in the implementation of student-centered recitation sessions and support the professional development of the TAs. The training includes…

There is very little in the way of dedicated subject-specific continuing professional development (CPD) provision for science teachers in special schools, nor for those who work in the mainstream, but have children with special educational needs in their classes. For the last two years, the Centre for Science Education (CSE) has been working with…

As part of a long-term program to develop effective, research-based professional development programs for physics graduate student teaching assistants (TAs), we first identify their current classroom practices and why they engage in these practices. In this paper, we identify a set of teaching practices we call "focusing on indicators,"…
