The first National Academies Summer Institute at Ohio State (NASI@OSU) was held June 8-12 at the Center for Life Sciences Education (CLSE). NASI@OSU was designed to improve how biology is taught to both majors and non-majors. It was led by Michelle Withers (West Virginia University) and Randy Phillis (University of Massachusetts - Amherst) and was patterned on the National Academies Summer Institutes (NASI), founded at the University of Wisconsin – Madison. The 21 participants developed group presentations of teachable tidbits that were peer-reviewed by organizers, facilitators, and participants. The process allowed the groups to practice assessing the effectiveness and student-centeredness of learning activities and to incorporate peer feedback into their teaching modules before using them in their own classes.
