Standards for Mathematical Practice
While the CCSS-M arguably provide an opportunity to focus efforts to improve schools, they also require teachers to make substantial changes to their instructional practices. To that end, we have developed an online, practice-based professional development program to help teams of teachers adapt their instructional practices to help their students enact the SMP. Each module supports the learning of one of the eight SMPs and consists of 3 parts (of 20-40 min duration each). Built on theories of practice-based professional development, every module includes opportunities to engage with representations of instructional practice, collectively learn to notice critical moves for supporting the SMP within such representations, practice critical moves with their own students in their own classrooms, and ultimately share their practice with peers and facilitators in order to receive feedback for improvement.
