Gloriana González is a Professor at the University of Illinois Urbana-Champaign. She studies mathematics classrooms with a particular focus on implementations of problem-based instruction through lesson study. Her current work supported by a National Science Foundation grant with Saad Shehab engages geometry teachers in lesson study for them to teach lessons using a human-centered design approach. Her experience implementing lesson study with pre-service and in-service teachers have prompted her enthusiasm for learning more about how this strategy can be used widely. The Lesson Study SIG community is a wonderful place to share this enthusiasm about lesson study!!
