With many examples and interesting historical asides, this book postulates an instructional methodology that could have been ours a century ago had John Stuart Mill included education as a science and not an art. More importantly, it shows that if today's educators adopt instruction that is consistent with Mill's methods, education could still become a science resulting in our schools improving dramatically. Coauthors Siegfried Engelmann and Douglas Carnine are foundational 20th and 21st century thinkers on the subject of instructional best practices. Engelmann shaped and codified Direct Instruction, the most effective method of teaching reading, math, and other subjects, as validated by more than 100 experimental studies. The authors' contention is that if the details of instruction are in place (well designed sets of examples and adequate practice), student learning can be accelerated far beyond what is currently being achieved in schools.
