Title: Making Space for Expansive Thinking in Socio-Technical Small-Group Undergraduate Discussions
In this qualitative case study, we explore how first- and second year undergraduate students make space for expansive thinking in their engineering modeling work. We focus on the ways in which one group of five women negotiated the inclusion of different social, political, and economic factors in their design model, particularly energy distribution and transboundary equity. Drawing on discourse analysis methods, we analyzed a small-group in-class discussion and identified five expansive moves that helped the students to make space for rethinking what they could include in their model. These included being explicit about their assumptions and uncertainties and acknowledging task difficulties.  more » « less

  1. Abstract Preservice secondary science teachers often experience science learning in narrow and marginalizing ways in their science preparation. These experiences cause harm, particularly for preservice teachers of color. They also limit the disciplinary resources they can develop for later teaching science in ways that value and sustain their students' ways of knowing and being in the world. Our research explores possibilities for cultivating new spaces for preservice secondary science teachers to engage in science. In a content‐focused education course, we designed for and studied preservice teachers' engagement in expansive and connective sensemaking, incorporating heterogeneity, power, and historicity in pursuits of explanatory accounts of the natural world. In this article, we examined how this course design can support preservice teachers to attune to heterogeneity in ways of knowing in science and to connect to identity and historicity in scientific sensemaking. Our analysis suggests that students' final projects reflected attunements to diverse knowing, communicating, and relating in science and deep connections with their identities and future‐making, yet had fewer connections to sociohistorical narratives and structures. We developed illustrative case studies of four student projects, highlighting the personal, social, and political possibilities of creating space for future educators to imagine more expansive and connective forms of science. This study contributes a novel model for preservice science teacher education to support teacher learning to value and sustain their students' ways of knowing and being in the world.

  2. This complete research paper describes the impact of a modeling intervention on first-year engineering students’ modeling skills in an introductory computer programming course. Five sections of the first-year engineering introductory programming course at a private, STEM+Business institution were revised to center around modeling concepts. These five sections made up the experimental group for this study. The comparison group consisted of four sections of the course that were not revised. Students in all these sections were given two different versions of a modeling problem two times in the semester to test their progress in gaining modeling skills. Each version required two submissions – a written solution and a coded solution. The assessment of these four submissions based on the three established dimensions of modeling were quantitatively analyzed in this study. The three dimensions within mathematical modeling that were the focus of this study were mathematical model complexity, modifiability, and reusability. Mathematical model complexity is being able to address the complexity of the problem. Modifiability addresses the generalizability of the model solution. Reusability is showing an understanding of the problem and the user. Statistical analysis showed that students in the experimental group had more gains in their demonstrated modeling abilities across all three dimensions than the students in the comparison group. This study demonstrated that intentional and explicit instructional strategies targeting model development resulted in greater gains in students’ demonstrated modeling skills and both their written and coded solutions to a complex modeling problem.

  3. Preservice elementary science teachers’ beliefs and practices influence the kinds of adaptations they make to curricula and the extent to which they are able to enact science lessons in justice-oriented ways. Through this qualitative study, we explored the beliefs and practices of five focal preservice teachers through an analysis of their lesson plans, recorded enactments, and interviews about their science teaching throughout their student teaching experience. We also introduce a framework for expansive sensemaking that integrates beliefs and practices related to four key themes: (1) believing in children’s brilliance, (2) building a collaborative classroom culture, (3) expanding what counts as science, and (4) positioning children as epistemic agents. While teachers varied in their beliefs about and approaches to each of these themes, they demonstrated strengths that illustrate what may be possible for early career teachers, like working to integrate many ways of knowing and being into science lessons, connecting to embodied knowledge, or supporting children to be scientific decision-makers. We discuss implications for teacher preparation programs and for theory development related to justice-oriented teaching in general and expansive sensemaking in particular.

  4. Abstract Interpreting and creating computational systems models is an important goal of science education. One aspect of computational systems modeling that is supported by modeling, systems thinking, and computational thinking literature is “testing, evaluating, and debugging models.” Through testing and debugging, students can identify aspects of their models that either do not match external data or conflict with their conceptual understandings of a phenomenon. This disconnect encourages students to make model revisions, which in turn deepens their conceptual understanding of a phenomenon. Given that many students find testing and debugging challenging, we set out to investigate the various testing and debugging behaviors and behavioral patterns that students use when building and revising computational system models in a supportive learning environment. We designed and implemented a 6-week unit where students constructed and revised a computational systems model of evaporative cooling using SageModeler software. Our results suggest that despite being in a common classroom, the three groups of students in this study all utilized different testing and debugging behavioral patterns. Group 1 focused on using external peer feedback to identify flaws in their model, group 2 used verbal and written discourse to critique their model’s structure and suggest structural changes, and group 3 relied on systemic analysis of model output to drive model revisions. These results suggest that multiple aspects of the learning environment are necessary to enable students to take these different approaches to testing and debugging.

  5. Flexible classroom spaces, which have movable tables and chairs that can be easily rearranged into different layouts, make it easier for instructors to effectively implement active learning than a traditional lecture hall. Instructors can move throughout the room to interact with students during active learning, and they can rearrange the tables into small groups to facilitate conversation between students. Classroom technology, such as wall-mounted monitors and movable whiteboards, also facilitates active learning by allowing students to collaborate. In addition to enabling active learning, the flexible classroom can still be arranged in front-facing rows that support traditional lecture-based pedagogies. As a result, instructors do not have to make time- and effort-intensive changes to the way their courses are taught in order to use the flexible classroom. Instead, they can make small changes to add active learning. We are in the second year of a study of flexible classroom spaces funded by the National Science Foundation’s Division of Undergraduate Education. This project asks four research questions that investigate the relationships between the instructor, the students, and the classroom: 1) What pedagogy do instructors use in a flexible classroom space? 2) How do instructors take advantage of the instructional affordances (including the movable furniture, movable whiteboards, wall-mounted whiteboards, and wall-mounted monitors) of a flexible classroom? 3) What is the impact of faculty professional development on instructors’ use of flexible classroom spaces? and 4) How does the classroom influence the ways students interpret and engage in group learning activities? In the first year of our study we have developed five research instruments to answer these questions: a three-part classroom observation protocol, an instructor interview protocol, two instructor surveys, and a student survey. We have collected data from nine courses taught in one of ten flexible classrooms at the University of Michigan during the Fall 2018 semester. Two of these courses were first-year introduction to engineering courses co-taught by two instructors, and the other seven courses were sophomore- and junior-level core technical courses taught by one instructor. Five instructors participated in a faculty learning community that met three times during the semester to discuss active learning, to learn how to make the best use of the flexible classroom affordances, and to plan activities to implement in their courses. In each course we gathered data from the perspective of the instructor (through pre- and post-semester interviews), the researcher (through observations of three class meetings with our observation protocol), and the students (through conducting a student survey at the end of the semester). This poster presents qualitative and qualitative analyses of these data to answer our research questions, along with evidence based best practices for effectively using a flexible classroom.
