From the source: student-centred guest lecturing in a chemical crystallography class

Abstract

Guest lecturing is an underutilized teaching strategy that provides depth and richness in college-level chemistry courses. The authors have found that studentcentred guest lecturing that combines themed guest presentations, hands-on workshops (whenever possible) and small group conversations has yielded tremendous benefits. As a result, students have developed a lasting interest in chemical crystallography and have employed advanced experiments in their own research. The authors report on their experience in planning student-centred guest lecturing, advise on best practices, and demonstrate the long lasting positive impact on student learning and engagement.
