Abstract Reformed science curricula provide opportunities for students to engage with authentic science practices. However, teacher implementation of such curricula requires teachers to consider their role in the classroom, including realigning instructional decisions with the epistemic aims of science. Guiding newcomers in science can take place in settings ranging from the classroom to the undergraduate research laboratory. We suggest thinking about the potential intersections of guiding students across these contexts is important. We describe the Classroom‐Research‐Mentoring (CRM) Framework as a novel lens for examining science practice‐based instruction. We present a comparative case study of two teachers as they instruct undergraduate students in a model‐based inquiry laboratory. We analyzed stimulated‐recall episodes uncovering how these teachers interacted with their students and the rationale behind their instructional choices. Through the application of the CRM Framework, we revealed ways teachers can have instructional goals that align with those of a research mentor. For example, our teachers had the goals of “creating an inclusive environment open to student ideas,” “acknowledging students as scientists,” and “focusing students on skills and ideas needed to solve biological problems.” We suggest three functions of research mentoring that translate across the classroom and research laboratory settings: (1) build a shared understanding of epistemic aims, (2) support learners in the productive use of science practices, and (3) motivate learner engagement in science practices.

Professional Decision Making: Reframing Teachers’ Work Using Epistemic Frame Theory
For many outside the profession, teaching looks simple and straightforward; however, for those working in classrooms, it can be a challenging task. In this paper we argue that teaching is a complex profession that requires both novice and expert educators alike to engage students in sets of activities aimed at transforming their understanding of a subject area. This work requires complex planning, enacting instruction, and reflecting on outcomes. In a moment to moment basis teachers must make decisions and iterate on previously made decisions in order to provide effective opportunities for students to engage with the materials, skills or content to be learned. In this paper, we aim to highlight the complexity of the decision-making process and, in doing so we make the argument that individual teachers’ decisionmaking draws upon a personal epistemic frame which includes factors such as skills, knowledge, identity, values, and epistemology. We provide examples of previous research efforts that have attempted to explore such factors and the limitations, both philosophical and methodological shortcomings of such attempts. Finally, we propose that the use of Quantitative Ethnography and Epistemic Frame Theory provides new opportunities to interrogate teachers’ practices and decision-making as a way to better understand the complexity of teacher work.

Scholars have suggested that one way to promote informed decision making about pressing socioscientific issues is to incorporate epistemic practices in science curricula. However, a key factor in teaching with such curricula is whether and how teachers can adapt instruction from their routine teaching approaches. Through an adaptive expertise lens, in this study, we examine how two teachers, teaching with agent-based computational complex systems models, varied in their implementations of epistemic practices and how consequently students' performance on epistemic practices was impacted. Through qualitative analyses of two teachers’ implementation recordings, this study examines teachers’ adaptive expertise in curricular implementations that aim at promoting student epistemic practices and provides examples of high and low levels of adaptive expertise that result in distinct student classroom experiences. This study carries implications for future teacher professional development geared towards improving students' epistemic practices.more » « less

Engineers are expected to make decisions in the context of design, which is ill-structured. Capstone courses serve as an opportunity for engineering students to engage in design and practice making decisions that do not have a single correct answer. Empirical research has demonstrated that when making such decisions, people use informal reasoning, of which there are multiple types: rationalistic, intuitive, and empathic. Despite this reality, engineering education often portrays decision making in the context of engineering design as objective. For example, capstone design instruction typically focuses on providing students with tools to facilitate rational reasoning alone. In this paper, we introduce a framework for informal reasoning that can be used to think critically about how we teach decision making in the context of engineering capstone design. In addition, we use this paper to briefly describe the ways in which capstone design conference attendees engaged with this framework when it was presented in a workshop during the 2018 Capstone Design Conference. To conclude, we present preliminary recommendations for capstone design educators to integrate more opportunities for diverse and realistic forms of reasoning in their teaching practices.more » « less

This fundamental research in pre-college education engineering study investigates the ways in which elementary school students and their teacher balance the tradeoffs in engineering design. STEM education reforms promote the engagement of K-12 students in the epistemic practices of disciplinary experts to teach content.1,2,3 This emphasis on practices is a paradigm shift that requires both extensive professional development and research to learn about the ways in which students and teacher learn about and participate in these practices. Balancing tradeoffs is an important practice in engineering but most often in classroom curricula it is embedded in the concept of iteration1,4; however, improving a design is not always the same as balancing trade-offs.1 Optimizing a multivariate problem requires students to engage in a number of engineering practices, like considering multiple solution, making tradeoffs between criteria and constraints, applying math and science knowledge to problem solving, constructing models, making evidence-based decisions, and assessing the implications of solutions5. The ways in which teachers and students collectively balance these tradeoffs in a design has been understudied1. Our primary research questions are, “How do teachers and students make decisions about making tradeoffs between criteria and constraints” and “How do experiences in teacher workshops affect the ways they implement engineering projects in their classes.” We take an ethnographic perspective to investigate these phenomena, and collected video data, field notes, student journals, and semi-structured interviews of eight elementary teachers in a workshop and similar data from two of the workshop teachers’ classes as they implemented the curriculum they learned in the workshop. Our analyses focus on the disciplinary practices teachers and students use to make decisions for balancing tradeoffs, how they are supported (or impeded) by teachers, and how they justify these decisions. Similarly, we compared two of the teachers wearing their “student hat” in the workshop as well as their “teacher hat” in the classroom5. Our analyses suggest three significant findings. First, teachers and students tended to focus on one criterion (e.g. cost, performance) and had few discussions about trying to minimize cost and maximize performance. Second, curriculum design significantly impacts the choices students make. Using two examples, we will show the impact of weighting criteria differently on the design strategies teachers and students make. Last, we noted most of the feedback given was related to managing classroom activity rather than supporting students’ designs. Implications of this study are relevant to both engineering educators and engineering curriculum developers.more » « less

To support teachers in providing all students with opportunities to engage in engineering learning activities, research must examine the ways that elementary teachers support how diverse learners engage with engineering ideas and practices. This study focuses on two teachers' verbal supports in classroom discussions across two class sections of a four-week, NGSS-aligned unit that challenged students to redesign their school to reduce water runoff. We examine the research question: How and to what extent do upper-elementary teachers verbally support students' engagement with engineering practices across diverse classroom contexts in an NGSS-aligned integrated science unit? Classroom audio data was collected daily and coded to analyze support through different purposes of teacher talk. Results reveal the purpose of teachers’ talk often varied between the class sections depending on the instructional activity and indicate that teachers utilized a variety of supports toward students' engagement in different engineering practices. In one class, with a large percentage of students with individualized educational plans, teachers provided more epistemic talk about the engineering practices to contextualize the particular activities. For the other class, with a large percentage of students in advanced mathematics, teachers provided more opportunities for students to engage in discussion and support for students to do engineering. This difference in supports may decrease the opportunities for some students to rigorously engage in engineering ideas and practices. This study can inform future research on the kinds of educative supports needed to guide teaching of integrated engineering activities for diverse students.more » « less
