Learning environments are vastly different across in-person and remote instruction. In undergraduate STEM courses, learning assistants (LAs) have been working in both settings, however, little is known about how the affordances and constraints of each setting influence LA facilitation practices in small group interactions. Thus, in our study, we explore the ways different contextual factors act as drivers of LA actions in both contexts of a hybrid course, and how these LA actions influence student in-the-moment learning. To do so, we recorded LA-student interactions and conducted interviews with the professor and LAs of a hybrid general chemistry course. We used a sociocultural perspective to provide an explanatory account for the drivers of action on LA facilitation practices and student learning, which revealed the following: When LA purposes/goals and social context were the same, but the conditions and means by which they could enact these purposes/goals were different between the in-person and remote conditions, LAs took different actions in each setting resulting in differences with respect to student in-the-moment learning. With our examples, we present evidence that there are multiple conditional factors that drive LA actions during LA-student interactions. Implications for theory and reform of practice will be discussed.

Characterizing facilitation practices of learning assistants: an authoritative-to-dialogic spectrum
Abstract BackgroundLearning assistants (LAs) increase accessibility to instructor–student interactions in large STEM lecture classes. In this research, we used the Formative Assessment Enactment Model developed for K-12 science teachers to characterize LA facilitation practices. The Formative Assessment Enactment Model describes instructor actions as eliciting or advancing student thinking, guided by their purposes and the perspective they center as well as by what they notice about and how they interpret student thinking. Thus, it describes facilitation practices in a holistic way, capturing the way purposes, perspectives, noticing, interpreting, and actions are intertwined and working together to characterize different LA actions. In terms of how perspectives influence actions, eliciting and advancing moves can be enacted either in authoritative ways, driven by one perspective that has authority, or in dialogic ways, driven by multiple perspectives. Dialogic practices are of particular interest because of their potential to empower students and center student thinking. ResultsOur analysis of video recordings of LA–student interactions and stimulated recall interviews with 37 introductory physical science lectures’ LAs demonstrates that instead of as a dichotomy between authoritative and dialogic, LA actions exist along a spectrum of authoritative to dialogic based on the perspectives centered. Between the very authoritative perspective that centers on canonically correct science and the very dialogic perspective that centers the perspectives of the students involved in the discussion, we find two intermediary categories. The two new categories encompass a moderately authoritative perspective focused on the LA’s perspective without the claim of being correct and a moderately dialogic perspective focused on ideas from outside the current train of thought such as from students in the class that are not part of the current discussion. ConclusionsThis spectrum further adds to theory around authoritative and dialogic practices as it reconsiders what perspectives can drive LA enactment of facilitation other than the perspective of canonically correct science and the perspectives of the students involved in the discussion. This emerging characterization may be used to give LAs and possibly other instructors a tool to intentionally shift between authoritative and dialogic practices. It may also be used to transition towards more student-centered practices.

Abstract BackgroundThe learning assistant (LA) model supports student success in undergraduate science courses; however, variation in outcomes has led to a call for more work investigating how the LA model is implemented. In this research, we used cultural historical activity theory (CHAT) to characterize how three different instructors set up LA-facilitated classrooms and how LAs’ understanding and development of their practices was shaped by the classroom activity. CHAT is a sociocultural framework that provides a structured approach to studying complex activity systems directed toward specific objects. It conceptualizes change within these systems as expansive learning, in which experiencing a contradiction leads to internalization and critical self-reflection, and then externalization and a search for solutions and change. ResultsThrough analyzing two semi-structured retrospective interviews from three professors and eleven LAs, we found that how the LA model was implemented differed based on STEM instructors’ pedagogical practices and goals. Each instructor leveraged LA-facilitated interactions to further learning and tasked LAs with emotionally supporting students to grapple with content and confusions in a safe environment; however, all three had different rules and divisions of labor that were influenced by their perspectives on learning and their objects for the class. For LAs, we found that they had multiple, sometimes conflicting, motives that can be described as either practical, what they described as their day-to-day job, or sense-making, how they made sense of the reason for their work. How these motives were integrated/separated or aligned/misaligned with the collective course object influenced LAs’ learning in practice through either a mechanism of consonance or contradiction. We found that each LA developed unique practices that reciprocally shaped and were shaped by the activity system in which they worked. ConclusionsThis study helps bridge the bodies of research that focus on outcomes from the LA model and LA learning and development by describing how LA learning mechanisms are shaped by their context. We also show that variation in the LA model can be described both by classroom objects and by LAs’ development in dialogue with those objects. This work can be used to start to develop a deeper understanding of how students, instructors, and LAs experience the LA model.more » « less

A central goal of the Learning Assistant (LA) model is to improve students’ learning of science through the transformation of instructor practices. There is minimal existing research on the impact of college physics instructor experiences on their effectiveness. To investigate the association between college introductory physics instructors’ experiences with and without LAs and student learning, we drew on data from the Learning About STEM Student Outcomes (LASSO) database. The LASSO database provided us with student-level data (concept inventory scores and demographic data) for 4,365 students and course-level data (instructor experience and course features) for the students’ 93 mechanics courses. We performed Hierarchical Multiple Imputation to impute missing data and Hierarchical Linear Modeling to nest students within courses when modeling the associations be- tween instructor experience and student learning. Our models predict that instructors’ effectiveness decreases as they gain experience teaching without LAs. However, LA supported environments appear to remediate this decline in effectiveness as instructor effectiveness is maintained while they gain experience teaching with LAs.more » « less

null (Ed.)The way teachers design activities and interact with students during instruction directly impacts students' opportunities to learn (OTL). Previous research has shown the merits of formative assessment (FA) in supporting students' active sense-making, leading to improved student success outcomes. We examined 22 STEM teachers' classroom videos, performing FA in class, taken from two different years of teaching in high-need districts. We then coded the videos according to two basic teaching moves - eliciting information about students' thinking or advanced learning. These moves can also be categorized as more authoritative (univocal) class discourse or more dialogic (multivocal). Our results show that thirteen out of the twenty-two teachers in this study diversified their teaching moves over time as they gained experience while persisting in high-need districts. The results also suggest five different teachers' clusters, representing different changes over time in these teachers' teaching moves. Teachers' reflections on challenges they faced while teaching and changes in their assessment practices over time suggest that changes in their teaching purposes resulted in shifting their teaching moves. These shifts supported their students' different challenges, building meaningful relationships with their students, and allowing them more OTL.more » « less

Phenomena‐based approaches have become popular for elementary school teachers to engage children's innate curiosity in the natural world. However, integrating such phenomena‐based approaches in existing science courses within teacher education programs present potential challenges for both preservice elementary teachers (PSETs) and for laboratory instructors, both of whom may have had limited opportunities to learn or teach science within the student and instructor roles inherent within these approaches. This study uses a convergent parallel mixed‐methods approach to investigate PSETs' perceptions of their laboratory instructor's role within a Physical Science phenomena‐based laboratory curriculum and how it impacts their conceptual development (2 instructors/121 students). We also examine how the two laboratory instructors' discursive moves within the laboratory align with their's and PSETs' perceptions of the instructor role. Qualitative data includes triangulation between a student questionnaire, an instructor questionnaire, and video classroom observations, while quantitative data includes a nine‐item open response pre‐/post‐semester conceptual test. Guided by Mortimer's and Scott's analytic framework, our findings show that students primarily perceive their instructors as a guide/facilitator or an authoritarian/evaluator. Using Linn's knowledge integration framework, analysis of pre‐/post‐tests indicates that student outcomes align with students' perceptions of their instructors, with students who perceive their instructor as a guide/facilitator having significantly better pre‐/post‐outcomes. Additional analysis of scientific discourse from the classroom observations illustrates how one instructor primarily supports PSETs' perspectives on authentic science learning through dialogic–interactive talk moves whereas the other instructor epistemologically stifles personally relevant investigations with authoritative–interactive or authoritative–noninteractive discourse moves. Overall, this study concludes by discussing challenges facing laboratory instructors that need careful consideration for phenomena‐based approaches.more » « less
