3. An Investigation into the Role of Dislocation Climb During Intermediate Temperature Flow of Mg Alloys

   Textured Mg alloy sheet samples were tensile tested parallel to the transverse direction, at Zener–Hollomon parameter values ranging from Z ~ 50 at room temperature and 10−3 s−1 down to Z ~ 18 at 350 °C and 10−5 s−1. At high Z, the samples exhibit strong texture evolution indicative of significant prismatic slip of dislocations with  Burgers vectors. Correspondingly, the plastic anisotropy is high, r ~ 4. At low Z, the texture evolution is minimal and the response is nearly isotropic, r ~ 1. Previously, it has been asserted that the high ductility and low plastic anisotropy observed at low Z conditions is due to enhanced activity of non-basal slip modes, including prismatic slip of  dislocations and pyramidal slip of  and  dislocations. The present results call this understanding into question and suggest that the enhanced ductility is more closely associated with the climb of  dislocations.

4. Board 305: HSI Implementation and Evaluation Project: Commitment to Learning Instilled by Mastery-Based Undergraduate Program (CLIMB-UP)

   Verdin, D.; Krinsky, S.; Raymond, D.; Schiorring, E.; Allen, E. L.; Perez, C. L. (June 2023, 2023 ASEE Annual Conference & Exposition)

   This is a board presentation at the 2023 ASEE Annual Conference describing the HSI Implementation and Evaluation Project: Commitment to Learning Instilled by Mastery-Based Undergraduate Program (CLIMB-UP). Commitment to Learning Instilled by a Mastery-Based Undergraduate Program (CLIMBUP) is an NSF IUSE:HSI project centered on re-designing courses with high non-completion rates (C- or lower) that have implications towards students’ graduation, transfer ability and retention. Despite decades of effort to create active, inquiry-based learning practices in classrooms, our institution continues to see equity gaps and many required courses with noncompletion rates exceeding 50%. Grading practices have been identified as one of the main culprits in the persistence of equity gaps. As a Hispanic Serving Institution, we recognize and value the diversity of experience that our students bring to our campuses and are committed to utilizing their strengths by creating datadriven, equitable grading practices that give students space to take risks and bring alternative viewpoints to our classrooms and be rewarded. We believe a Mastery-Based Grading (MBG) approach can address problems that a traditional grading approach has caused. The CLIMB-UP project is building the infrastructure to support and train STEM faculty (both tenure-line and adjuncts) to redesign and teach a Mastery-Based Graded (MGB) course, and is conducting research on faculty experiences and on the change in student attitudes, mindsets, and outcomes.
