Good mentoring can have a positive and lasting effect on the professional careers and lives of students, should be based on guidance and trust, and should be of lasting value to both the student and mentor. Although the educational literature suggests that successful mentoring is crucial for those in research leadership positions, and further that mentoring is a learned skill, there are often no opportunities for most graduate students to develop mentoring skills. Our IGERT program integrates formal mentoring training into the IGERT experience by having all IGERT trainees participate in the Graduates Linked with Undergraduates in Engineering (GLUE) mentoring program. Each IGERT trainee will mentors an undergraduate student and receives feedback from the undergraduate student he/she mentors. Co-founded by Dr. Kinney (IGERT co-PI) and the Women in Engineering Program (WEP) in 2001, the GLUE program provides an innovative opportunity to expose undergraduate students to research by linking them with graduate student mentors working on research projects. The program consists of a semester of research experience in which the undergraduate students work three to five hours per week with their graduate mentors on their research. This experience is coupled with a structured interdisciplinary seminar course for the undergraduate students and mentoring and career development workshops for the graduate mentors. By involving IGERT trainees as graduate mentors in GLUE, we will expand the program beyond the College of Engineering to include the other IGERT participating colleges. These mentoring efforts will contribute to the recruitment and retention of underrepresented groups in science and engineering graduate programs, a central goal of the proposed IGERT program, while providing IGERT trainees with a unique experience to develop their own mentoring skills.
