Transformational geometry, one part of transforming geometry instruction
Summary: The traditional high school suffers from ineffective pedagogy, a problematic approach to proof, and a rigid separation from other parts of the secondary math curriculum. Transformational geometry can help address those limitations: it can be used to bring in new approaches to teaching, broaden, and deepen the understanding of proof, and make connections with several other parts of mathematics. Unfortunately, bringing a transformational approach to schools is hampered by a lack of clarity and the weight of tradition. Henri Picciotto will suggest some possibly useful guidelines to facilitate this transition, including what topics should be prioritized in preservice training.
Duration: 60 minutes
Format: Online seminar via Zoom web meeting software with questions and discussion. Detailed instructions for joining the seminar will be emailed to registered participants.
Henri Picciotto is a math education consultant, retired from the classroom after 42 years of teaching at every level from counting to calculus. He is a leading authority on the use of manipulatives and geometric puzzles in secondary school. He is the author of Geometry Labs, a book of discussion-generating hands-on activities, and the co-author with George Hart of Zome Geometry, a guide to the exploration of polyhedra and much more. Henri shares his ideas about teaching, and much curriculum, on his Math Education Page and his Math Education Blog.
