Project Lead The Way (PLTW) is a nonprofit transforming schools with problem-based computer science, engineering, and biomedical science programs in over 8,000 schools. I led the creation of the PLTW Computer Science pathway and co-wrote our Introduction to Computer Science and our instance of the new AP CS Principles, Computer Science and Software Engineering. I trained the initial 40 and 60 pilot teachers for those courses. Between a BS in physics at M.I.T and my work at PLTW, I taught at inner-city and suburban high schools for 15 years. LinkedIn profile.
