Teaching space-group diagrams to chemistry students through a peer-tutoring approach

Peer tutoring is a teaching strategy that offers a creative way of getting students more involved and accountable for their own learning in college-level chemistry courses. The authors have found that the 'Symmetry and Space Group Tutorial' [Jasinski & Foxman (2007). Symmetry and Space Group Tutorial, V1.55. http:// people.brandeis.edu/similar to foxman1/teaching/indexpr.html] lends itself well to a peer-tutoring approach in a crystallography course for chemistry students. This in-class activity provides an opportunity for students to learn space-group diagrams, understand basic symmetry concepts, organize what they have learned, and explain it to their peers, which leads to a deeper overall understanding of the subject. We report on our experience in planning peer tutoring, advise on best practices, and demonstrate the positive impact on student learning and engagement.
