Written by veteran journalist Shepard Barbash over a period of 10 years, Clear Teaching is a well-researched, highly readable introduction to Direct Instruction (DI), a systematic teaching approach which for more than 40 years has dramatically improved learning outcomes for students of all abilities and from all walks of life. The book looks at the development of DI through the early experiences of its creator, Zig Engelmann; explains the principles that underpin this approach; and looks at DI's reception in the world of teaching, where it has been effectively shunned despite a formidable research base and example after example of transformative success.
