Research Foundations
In the 1960s, Dr. Siegfried “Zig” Engelmann conducted focus groups with his and other neighborhood children to determine how they learn and remember new information. Based on his observations, he developed a variety of instructional techniques that enabled even the youngest participants to master sophisticated skills and concepts. These techniques evolved into a full-fledged teaching method called "Direct Instruction." In collaboration with Dr. Wesley Becker, Engelmann published the first Direct Instruction program—DISTAR® (Direct Instruction System for Teaching Arithmetic and Reading)—a few years later.
In 1977, Project Follow Through, the largest education study ever conducted, determined Direct Instruction to be the most effective instructional approach—yielding the greatest improvements in basic academic skills, problem-solving skills, and self-esteem—out of all 22 models studied. Since then, DI programs have been implemented in thousands of schools across the world.
McGraw Hill is proud to be the primary publisher of Direct Instruction programs, a partnership dating back to 1991, when our company acquired SRA.
