Title: Beyond Instructional Practices: Characterizing Learning Environments that Support Students in Explaining Phenomena
Many conversations surrounding improvement of large-enrollment college science, technology, engineering & mathematics (STEM) courses focus primarily (or solely) on changing instructional practices. By reducing dynamic, complex learning environments to collections of teaching methods, we neglect other meaningful parts of a course ecosystem (e.g., curriculum, assessments). Here, we advocate extending STEM education reform conversations beyond “active versus passive learning.” We argue communities of researchers and instructors would be better served if what we teach and assess was discussed alongside how we teach. To enable nuanced conversations about the characteristics of learning environments that support students in explaining phenomena, we defined a model of college STEM learning environments which attends to the intellectual work emphasized and rewarded on exams (i.e., assessment emphasis), what is taught in whole-class meetings (i.e., instructional emphasis), and how those meetings are enacted (i.e., instructional practices). We subsequently characterized three distinct chemistry courses and qualitatively examined the characteristics of chemistry learning environments that effectively supported students in explaining why a beaker of water warms as a white solid dissolves. Furthermore, we quantitatively investigated the extent to which measures of incoming preparation explained variance in students’ explanations relative to enrollment in each learning environment. Our findings demonstrate that learning environments that effectively supported learners in explaining dissolution emphasized how and why salts dissolve in-class and on assessments. Changing teaching methods in an otherwise traditionally structured course (i.e., a course organized by topics that primarily assesses math and recall) did not appear to impact the sophistication of students’ explanations. Additionally, we observed that learning environment enrollment explained substantially more of the variance observed in students’ explanations than measures of precollege math preparation. This finding suggests that emphasizing and rewarding the construction of causal accounts for phenomena in-class and on assessments may support more equitable achievement.  more » « less

    What we emphasize and reward on assessments signals to students what matters to us. Accordingly, a great deal of scholarship in chemistry education has focused on defining the sorts of performances worth assessing. Here, we unpack observations we made while analyzing what “success” meant across three large-enrollment general chemistry environments. We observed that students enrolled in two of the three environments could succeed without ever connecting atomic/molecular behavior to how and why phenomena happen. These environments, we argue, were not really “chemistry classes” but rather opportunities for students to gain proficiency with a jumble of skills and factual recall. However, one of the three environments dedicated 14–57% of points on exams to items with the potential to engage students in using core ideas (e.g., energy, bonding interactions) to predict, explain, or model observable events. This course, we argue, is more aligned with the intellectual work of the chemical sciences than the other two. If our courses assess solely (or largely) decontextualized skills and factual recall we risk (1) gating access to STEM careers on the basis of facility with skills most students will never use outside the classroom and (2) never allowing students to experience the tremendous predictive and explanatory power of atomic/molecular models. We implore the community to reflect on whether “what counts” in the courses we teach aligns with the performances we actually value.

    Answering questions and solving problems are critical skills that affect the quality of life for all people. The content areas of science and engineering traditionally and most directly address the processes of inquiry and problem‐solving. While there is an increasing body of research surrounding teaching academic content (i.e., mathematics and science) as well as skills that are critical to support student success in these areas (i.e., communication and self‐determination), the research supporting instruction of math, science, and engineering practices and processes are only emerging. The purpose of this article is to provide a research‐based framework for instructional design that provides ideas for cognitive accessibility and support for students with MSD in STEM. The framework aims to guide teachers in considering why to teach STEM, what to teach, and how to teach it. The framework guides teachers to use evidence‐based practices in special education to teach students to know about STEM (i.e., academic content), do STEM practices and processes (i.e., critical thinking skills combined into routines for asking questions or solving problems), and think in ways that support this learning (i.e., metacognitive behaviors).

    The use of educational digital games as supplemental tools to course instruction materials has increased over the last several decades and especially since the COVID-19 pandemic. Though these types of instructional games have been employed in the majority of STEM disciplines, less is known about how diverse populations of students interpret and define the value of these games towards achieving academic and professional pursuits. A mixed-method sequential exploratory research design method that was framed on the Technology Acceptance Model, Game-Based Learning Theory and Expectancy Value Theory was used to examine how 201 students perceived the usefulness of an intuitive education game that was designed to teach engineering mechanics used in designing civil structures. We found that students had different expectations of educational digital games than games designed for entertainment used outside of classroom environments. Several students thought that the ability to design their own structures and observe structure failure in real-time was a valuable asset in understanding how truss structures responded to physical loading conditions. However, few students thought the educational game would be useful for exam (14/26) or job interview (19/26) preparation. Students associated more value with engineering games that illustrate course content and mathematical calculations used in STEM courses than those that do not include these elements.

    Prior to COVID-19 and the shift to fully online instruction, teacher preparation programs were teaching candidates to use technology in the classroom, but they were not focusing on how to teach in exclusively online or hybrid models. In the future, all preservice teachers will need to know how to teach online, whether due to necessity or by choice. Therefore, the purpose of our research is to first identify essential elements of critical digital pedagogy for facilitating online inquiry, and then to integrate these methods into our teacher preparation program to prepare preservice teachers to facilitate inquiry-based science, technology, and mathematics (STEM) effectively in online learning environments that are equitable and inclusive of all learners. We utilize a mixed-methods approach with quantitative and qualitative measures including literature reviews, individual interviews, focus groups, program documents, and efficacy surveys. Drawing on this data, this presentation shares the findings from the first part of this three-year research project by discussing essential elements of critical digital pedagogy for facilitating online STEM inquiry. We identify what tools and instructional approaches can be used to support STEM learning in online environments in ways that will support all students, including those who are traditionally marginalized in U.S. schools.

    Many educators and professional organizations recommend Quantitative Reasoning as the best entry-level postsecondary mathematics course for non-STEM majors. However, novice and veteran instructors who have no prior experience in teaching a QR course often express their ignorance of the content to choose for this course, the instruction to offer students, and the assessments to measure student learning. We conducted a case study to investigate the initial implementation of an entry-level university quantitative reasoning course during fall semester, 2018. The participants were the course instructor and students. We examined the instructor’s motives and actions and the students’ responses to the course. The instructor had no prior experience teaching a QR course but did have 15 years of experience teaching student-centered mathematics. Data included course artifacts, class observations, an instructor interview, and students’ written reflections. Because this was a new course—and to adapt to student needs—the instructor employed his instructional autonomy and remained flexible in designing and enacting the course content, instruction, and assessment. His instructional decision making and flexible approach helped the instructor tailor the learning activities and teaching practices to the needs and interests of the students. The students generally appreciated and benefited from this approach, enjoyed the course, and provided positive remarks about the instructors’ practices.
