Mark Daubenmier has been teaching AP computer science for 15 years at Columbus Academy in addition to math and other computer science courses. Part of his educational philosophy is that it is no longer sufficient to master the content of a course. In order to remain competitive in today's global marketplace, students also need to bring to the table other skills, such as the ability to collaborate well with others.
