Social Networks And Instructional Reform In Stem: The Teaching‑Research Nexus, John Skvoretz, Katherine Kappelman, Ariel Marcy, Jacob D. Mcalpin, Jennifer E. Lewis, John P. Ziker, Karl Mertens, Brittnee Earl, Susan E. Shadle, Brian A. Couch, Stephanie Feola, Luanna B. Prevost, A. Kelly Lane, Blake Whitt, Marilyne Stains

School of Biological Sciences: Faculty Publications

Instructional reform in STEM aims for the widespread adoption of evidence based instructional practices (EBIPS), practices that implement active learning. Research recognizes that faculty social networks regarding discussion or advice about teaching may matter to such efforts. But teaching is not the only priority for university faculty – meeting research expectations is at least as important and, often, more consequential for tenure and promotion decisions. We see value in understanding how research networks, based on discussion and advice about research matters, relate to teaching networks to see if and how such networks could advance instructional reform efforts. Our research examines …

School of Biological Sciences: Faculty Publications

Instructors use a variety of online formative assessment (FA) activities to support learning outside class. Previous studies have revealed barriers for students in online courses, but little is known about the barriers students experience when completing online FA assignments. Understanding these barriers to access is critical to fostering more inclusive learning for all students. Using a framework from previous work in online learning, we examined student perceptions of online FA access with respect to five barrier categories: technical resources, instructor organization, social interactions, personal engagement, and learning environment. We developed and administered a survey to more than 1,200 undergraduate biology …

It Takes Brains: Cultivating The Learning Process For Effective Science Communication, Amy D. Hauver

Doctor of Plant Health Program: Dissertations and Student Research

Learning is a complex, subjective process. An important perspective on learning is that anyone, regardless of their level of education, can participate in learning about science and contribute to their community. The public increasingly looks towards online resources to find answers to challenges, so it is necessary that people become empowered to take information about issues rooted in science and apply them to their own lives and communities. In my experiences as a learner and educator, understanding the learning process provides a framework to design successful learning environments.

Since the brain is the organ most closely associated with the process …

Reflection Types And Students’ Viewing Of Feedback In A First-Year Engineering Course Using Standards-Based Grading, Heidi A. Diefes-Dux, Laura M. Cruz Castro

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Background: Feedback is one of the most powerful and essential tools for learning and assessment, particularly when it provides the information necessary to close an existing gap between actual and reference levels of performance. The literature on feedback has primarily focused on addressing strategies for providing effective feedback rather than aspects of students’ readiness to engage with feedback. Purpose/Hypothesis: This study investigated whether reflection, as a routine pedagogical intervention grounded in self-regulated learning theory, promotes the frequency with which students view feedback. Design/Method: A quasi-experimental design was employed to examine the relationship between the use of four different reflection types, …

Conflict Of Allegiance: Professional Development Challenges In Transforming Science Teachers' Identities And Practices, Elizabeth B. Lewis

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Case studies of two biology teachers, Cathy and David, from the same minority-majority, urban U.S. high school, provide insights into their instructional practices while they engaged in long-term professional development (PD). Findings suggest why science teachers engaged with PD may, or may not, adopt more adaptive pedagogical approaches in the service of reform-based teaching. Gee’s institution- and affinity-identity constructs were used as analytic lenses regarding teachers’ perceptions of teaching, learning, and agency in the dual contexts of their school’s institutional environment and PD community. Over time, Cathy adopted more inquiry-based instructional practices she learned through PD seminars in building a …
