STEM education centers: catalyzing the improvement of undergraduate STEM education.

BACKGROUND: With the remarkable attention being paid to STEM education nationally, with the growing engagement of universities and colleges in STEM education reform, and with the rise of STEM education centers, SECs, assisting universities as they strive to achieve these reforms, this research provides insight into the roles of six SECs. Through a multi-dimensional cross-site comparison, we provide a lens into the ways in which SECs function on their campuses, illuminating possibilities for those seeking to strengthen undergraduate STEM education. RESULTS: SECs play an important networking role on their campuses, where they inform and unify institutional efforts, serving to elevate their visibility and importance both internally and externally. Through their scholarship, SECs contribute to the knowledge base and provide funding, which add resources and incentives for the implementation of evidence-based instructional practices (EBIPs) and STEM education research. SECs augment these efforts with the assessment and evaluation of learning outcomes and curricular innovations. Additionally, SECs act as an internal resource for faculty and instructors providing programs and training to foster the application of EBIPs in STEM courses. Several SECs provide the infrastructure for broader impact activities, and act as an external funding resource. CONCLUSIONS: STEM education centers make key contributions to their institutional environments. While the individual roles of these SECs on their campuses are distinctly unique, an in-depth look across six SECs reveals common areas of focus that allow these centers to enhance the undergraduate teaching and learning experience. Our results suggest that the ability of SECs to link STEM education research with teaching and learning initiatives provides a breadth of impact and attention across organizational levels. The analysis describes the ways in which these centers support institutional goals for undergraduate STEM education and relates these to areas of national priority. This research was carried out as part of a broader study, which informs the organizers of NSEC, the network of STEM education centers.

Human Brains Engaged in Rat Brains: Student-driven Neuroanatomy Research in an Introductory Biology Lab Course.

Inquiry-based laboratory instruction has been shown to actively engage students in the content and skills being taught. These courses are further intended to teach students not only what is known, but also the process by which investigators come to know it. We sought to take this approach one step further and incorporate novel research questions into an inquiry-based laboratory model early in the undergraduate course of study. In this research-based introductory laboratory course, first-year students acquired basic lab skills not just for their own sake, but rather within the context of a research question of a member of the faculty. Student projects investigated potential neuroanatomical changes in animal models of dyslexia and aging and included measurements of neuron numbers and levels and distribution of neuronal proteins. Students played an active role in designing and implementing an experimental plan, explored data analysis techniques, and reflected on the results that they obtained in scholarly forms such as research papers and a departmental poster session. Student feedback on this approach has been extremely positive, and the data collected were research quality preliminary data that are being actively pursued for further study. Based on our encouraging experiences, we conclude that designing an introductory course around novel research, including some assessments modeled after scholarly practices, provides motivation and excitement for the students, instills good scientific habits, and can potentially benefit departmental research.
