Herausforderung Peer Instruction - Bem\"uhungen um einen doppelten Konzeptwandel in der Lehre

The teaching style “Peer Instruction”, developed by Eric Mazur (Harvard University), poses a twofold challenge to teachers as well as students. While it aims to promote conceptual development in students, it also demands significant shifts in role differentiation of students and teachers, who are generally still accustomed to a lecture-style setting. In this paper, experiences with this method converge with a constructivist theory of learning to formulate thoughts and advice on how to address several perceived challenges.
