Preservice elementary teachers' perceptions of their science laboratory instructors in a phenomena‐based laboratory and how it impacts their conceptual development
Title: Preservice elementary teachers' perceptions of their science laboratory instructors in a phenomena‐based laboratory and how it impacts their conceptual development
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

Abstract Students are more likely to learn in college science, technology, engineering, and math (STEM) classrooms when instructors use teacher discourse moves (TDMs) that encourage student engagement and learning. However, although teaching practices are well studied, TDMs are not well understood in college STEM classrooms. In STEM courses at a minority-serving institution (MSI; n = 74), we used two classroom observation protocols to investigate teaching practices and TDMs across disciplines, instructor types, years of teaching experience, and class size. We found that instructors guide students in active learning activities, but they use authoritative discourse approaches. In addition, chemistry instructors presented more than biology instructors. Also, teaching faculty had relatively high dialogic, interactive discourse, and neither years of faculty teaching experience nor class size had an impact on teaching practices or TDMs. Our results have implications for targeted teaching professional development efforts across instructor and course characteristics to improve STEM education at MSIs.

A challenge instructors face is developing and accurately assessing technical communication skills to ensure students can apply and transfer the skills from the academic context into the context of engineering practice. By intentionally balancing teaching transferrable communication skills relevant to engineering practice and evaluating student understanding, engineering educators can foster competence and prepare students for the expectations of their professional careers. This study addresses two questions: (1) how can chemical engineering instructors reliably and consistently assess student communication skills, and (2) are instructor expectations aligned with those of practicing engineers? The use of well-designed rubrics is important for setting clear expectations for students, providing constructive feedback, and in team taught courses, grading consistently. This study discusses how a rubric for assessing technical communication skills in senior-level chemical engineering laboratory reports was validated and demonstrated reliability across five chemical engineering instructors. Additionally, five industry partners evaluated student reports for comparison to instructor rubric scores. Expectations and perceptions of the quality of student work align between instructors and practicing engineers, but practicing engineers prioritized safety and abstract clarity, while instructors prioritized the students’ abilities to interpret results and draw conclusions.

Limited access to undergraduate research experiences for science, technology, engineering, and mathematics students has led to creation of classroom-based opportunities for students to participate in authentic science. Revising laboratory courses to engage students in the practices of science has been shown to have many benefits for students. However, the instructor’s role in successful implementation of authentic-inquiry curricula requires further investigation. Previous work has demonstrated that navigating an instructional role within the open-ended format of an inquiry curriculum is challenging for instructors. Little is known about effective strategies for supporting students in authentic scientific practices. To address this challenge, we investigated instructors with prior experience teaching Authentic Inquiry through Modeling in Biology (AIM-Bio) in order to reveal strategies that are likely to help students succeed in this context. We took a unique approach that uncovered how instructors supported students and how they intended to support students in the scientific practices of modeling and experimental design. Analysis included in vivo recordings of instructor–student interactions paired with instructor interviews over the course of a semester. Findings detail the ways in which instructors flexibly responded to students through their in-the-moment actions. Additionally, the instructor intentions provided crucial explanatory power to explain the rationale behind teaching choices made.

This preliminary report shares an outcome from a summer professional development (PD) activity with university instructors. Instructors participated in four PD meetings, then immediately taught a five-day summer workshop using inquiry, working primarily with first-generation minoritized students. While instructor participants’ exit interviews of the project identified their experience in the summer PD as pivotal to their development, we know little of how students experienced the instructors’ teaching during the workshop. Our analysis focuses on two items from student post-workshop survey wherein students shared their feedback of their instructor and their experiences more broadly. This analysis allowed us to get a good sense of the instructors’ individual practices and revealed convergence in their practices. Pedagogically, instructors utilized group work and deemphasized direct instructions, while prioritizing students’ engagement in discussions and struggling through conceptual ideas. Relationally, instructors were responsive to students’ mathematical needs and created a respectful, safe, and welcoming classroom environment.

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.
