The document discusses teaching strategies using technology, focusing on Just-in-Time Teaching (JiTT). It describes JiTT as a pedagogical approach developed by Gregor Novak that uses web exercises called "warm-ups" to prepare students for class. Students complete warm-ups outside of class and faculty use student responses to adjust their lessons. The goal is to improve learning through increased student-teacher and student-student interaction. JiTT promotes self-checking of knowledge using interactive lessons that can be accessed anywhere via mobile devices.
