Graduate Student Mentoring Develop curriculum for summer skill-building exercises Active mentoring of undergraduate research projects
Assessment Planning evaluation and assessment procedures in coordination with strong mathematical education community at ASU Annual evaluations of course work, summer workshops and mentoring by students and faculty Staff support for database on participants and subsequent success: How many under-represented minorities completed at least one year of the UBM program, and comparison of how they perform on end-of-year math reasoning test compared to pre-test given during recruitment How many continue in second year in this or similar program? How many complete bachelor’s degrees within 4 years? How many enter graduate or medical school, or obtain relevant employment?
