Over the past decade, increasing numbers of institutions have reported using undergraduate students as instructors in science and technology courses. Undergraduates are most commonly used as assistants to graduate students, staff, or faculty who are the primary instructors for the course or lab/recitation section. In some cases, however, undergraduates are the primary instructors, responsible for running the lab or recitation, grading, and holding office hours. In the Biology Department at SUNY-Geneseo, undergraduate laboratory instructors (ULIs) have the unusual role of being the primary instructors for a freshman-level investigative lab course. The authors were interested in whether undergraduates with little or no research experience can teach the scientific process. Using exit surveys of biology students they examine whether undergraduate instructors can teach investigative labs, and share perspectives on the challenges of working with undergraduate lab instructors.
