One the main challenges in achieving consistency in the curriculum is the delivery and coordination of multi-section introductory courses. The mix of adjunct, new, and seasoned instructors, the frequent changes in course content and learning goals, and the non-homogeneous student body are some of the factors that makes successfully teaching such courses a challenge. In this paper we describe how the course mentoring project combines personal involvement with a technological solution to build an effective knowledge-sharing virtual community. Course mentoring has proven to be an efficient way to address and overcome the challenges of teaching introductory computer science courses.
