Educational Innovations

A Mineralogy Mentor program is supported by the CAREER award.

Two upper-level undergraduates serve as peer-mentors to students taking GG301. Mentors attend all labs, meet with students in informal study sessions, meet with TA outside of class, and develop educational resources in collaboration with the instructor. Undergraduate Student Accomplishments • Undergraduate Lisa Tatsumi is pursuing research in experimental petrology with a Vice Chancellor’s Summer Research Award, 2006 • A Mineralogy student participated in a national Research Experience for Undergraduates (REU) program, 2004 • A Mineralogy student was recognized by the Mineralogical Society of America and received the American Mineralogist Undergraduate Award, 2004
