  • Building Excellence in Scientific Teaching: How Important Is the Evidence for Evidence-Based Teaching when Training STEM TAs?
Title: Building Excellence in Scientific Teaching: How Important Is the Evidence for Evidence-Based Teaching when Training STEM TAs?
ABSTRACT Evidence-based teaching practices (EBTP)—like inquiry-based learning, inclusive teaching, and active learning—have been shown to benefit all students, especially women, first-generation, and traditionally minoritized students in science fields. However, little research has focused on how best to train teaching assistants (TAs) to use EBTP or on which components of professional development are most important. We designed and experimentally manipulated a series of pre-semester workshops on active learning (AL), dividing subjects into two groups. The Activity group worked in teams to learn an AL technique with a workshop facilitator. These teams then modeled the activity with their peers acting as students. In the Evidence group, facilitators modeled the activities with all TAs acting as students. We used a mixed-methods research design (specifically, concurrent triangulation) to interpret pre- and post-workshop and post-semester survey responses. We found that Evidence group participants reported greater knowledge of AL after the workshop than Activity group participants. Activity group participants, on the other hand, found all of the AL techniques more useful than Evidence group participants. These results suggest that actually modeling AL techniques made them more useful to TAs than simply experiencing the same techniques as students—even with the accompanying evidence. This outcome has broad implications for how we provide professional development sessions to TAs and potentially to faculty.  more » « less

    ABSTRACT Graduate teaching assistants (GTAs) teach undergraduates directly, and many are future faculty, making it particularly important for them to be trained in using evidence-based instructional practices. We implemented and assessed a teaching professional development program for 19 biology GTAs aimed to help them develop their teaching perspectives and improve their teaching self-efficacy. The program consisted of a pre-semester bootcamp of pedagogical workshops, mentoring sessions throughout the semester, crafting a teaching philosophy statement, and reflective peer teaching observation. We surveyed and interviewed students throughout the program to assess their growth and identify elements of the program that supported their growth. We found that participants’ self-efficacy improved immediately following the pre-semester bootcamp, but these improvements did not persist throughout the semester. At the end of the semester, participants’ teaching self-efficacy did not differ from GTAs in the department who did not participate in our program. Throughout the semester, our participants shifted toward the social reform perspective of teaching, which views good teaching as encouraging students to critically evaluate information and give them power to take social action to improve their lives. At the end of the semester, our participants more strongly endorsed the social reform perspective of teaching than GTAs who did not participate in our program. Our results suggest that pre-semester workshops supported novice GTAs before their class, but more sustained interactions may be needed for these boosts to persist. Our results also suggest that encouraging GTAs to reflect on what makes good teaching can help them solidify a coherent teaching perspective.

    Despite the intent to advance engineering education with NGSS, teachers across all grades lack self-efficacy in engineering pedagogy. Instructional shifts envisioned by NGSS, especially with inclusion of engineering, require substantial learning by teachers. For rural schools, due to geographic location and smaller collegial networks, there are challenges in providing content-specific professional learning. This project gathered researchers from four states to provide PL aligned to NGSS and delivered remotely to 150 rural teachers. In summer 2023, experts led a five-day workshop which modeled shifts called for by NGSS (e.g., equitable, discourse-rich, phenomena-based) and provided opportunities to experience next-generation teaching and learning. Likert scale surveys were collected before and after the workshop to gauge self-efficacy regarding teaching science and engineering. We found that science-focused PL, with engineering embedded rather than as stand-alone component, afforded growth in self-efficacy for teaching engineering. Pre-workshop surveys showed that teachers had higher self-efficacy towards teaching science than teaching engineering (Wilcoxon signed-rank; p<.001). Positive attitudes toward teaching science were leveraged to provide PL and pre-workshop to post-workshop analysis showed growth in self-efficacy towards teaching engineering (p<.001). Results are important for professional learning around teaching engineering, for professional learning with rural teachers, and for remote access to professional learning.

    Assessment of the impact of teacher professional development is seldom accomplished by asking their students. This study addresses whether self-reported changes in teacher practices align with their students’ perceptions of changes in teaching practices. Participants were 39 teachers from two US states that completed at least 15 teaching sessions totaling more than 3.5 hours of teacher professional development (practice teaching) inside the simulated teaching environment of simSchool. The goals of the professional development were remediation of implicit bias in teaching practices and fostering equity in teaching. Pre-post surveys were completed by the teachers before and after the professional development sessions. Concurrent pre and post surveys were administered to 800 of the teachers’ G3-12 students. This study presents the results of examining whether teacher-reported changes in their teaching practices can be shown to align with changes reported by their students.

    To promote interest in computer science (CS) among minority high school students from low-income families, we offered a one-month Summer Academy followed by a semester-long online group project. A group of 31 minority students from Alabama’s Black Belt areas participated in the program. The purpose of this study was two-fold. First, we examined factors affecting students’ motivation for learning CS. Second, we explored the program’s impact on student's future interest in learning CS. We conducted an individual Zoom interview with all participants, and they were also invited to complete a pre-and post-survey. We also observed classroom teaching during the Summer Academy and facilitated online Zoom meetings in the fall semester on a monthly basis. The findings revealed that early exposure to CS and family encouragement motivated students to explore the field of CS. Students found MIT App Inventor learning, meeting with guest speakers, and group projects most valuable, which positively affected students’ motivation to continue to learn CS.
