Delaware Math Coalition leaders are committed to the use of high quality instructional materials (HQIM) and providing sustained support to assist teachers and coaches in more skillfully enacting lessons from their HQIM. The organization’s professional learning model is grounded in research (Kersting et. al, 2010, 2012, 2015) that has been correlated with more ambitious teaching and higher student achievement in mathematics. The approach utilizes four-part lesson study video analysis cycle that is purposefully designed to engage teachers and coaches in mathematically intense planning to teach and reflection conversations. As part of the cycle, teachers and coaches:

• unpack target lessons from their high quality instructional materials and identify the intended learning goal(s) of the lesson;
• focus on getting beyond the nuts and bolts of their lessons by identifying critical moments in the lesson’s mathematical trajectory;
• make predictions about how students’ conceptions about the key ideas will evolve across the lesson; and
• analyze video with a goal of understanding student thinking and considering ways to further enhance students’ opportunities to make progress with the intended lesson learning goal.
