This week Tyree Alexander (of episode 5 fame) stops by to take us behind the scenes on the award-winning computer science program he started at his public school in the South Bronx. We discuss the conditions that lend themselves most favorably to starting and sustaining exciting new programs at school that go above and beyond what is required of teachers but support some of students' most pressing needs. This is part 1 of a two-part episode: to hear the second part, meet us at patreon.com/professionaldevelopment
