Abstract: This presentation focuses on the rationale, design, and development of the eMentoring modules that train graduate students for peer or near peer mentoring, which is part of a larger grant funded project supporting underrepresented minority women students enrolled in STEM programs to 1) aid their self-efficacy, 2) facilitate their success in the STEM degree and workplace, and, therefore, 3) help increase the number of women completing STEM degrees and entering the STEM workforce. The participants of the presentation will learn not only why training for mentorship is important but also design and development considerations for developing this training in an online medium.
