The purpose of this article is not to study and interpret the research, so we won't go into that research in detail, but we all know, both intellectually and emotionally, that a guaranteed and
viable curriculum produces results, so let's get to work on that piece of the solution first.
As the research tells us, if that
curriculum is guaranteed — taught in every classroom — and
viable — aligned to the standards and assessment system — then that can and will
produce improvements of 25 to 40 percent, depending on whose research you read; Lezotte, Reeves, Schmoker, Hattie or others.
