Direct Instruction (DI) programs are based on over 40 years of research on how children learn and the most effective ways to teach. Studies involving DI curricula and its implementation have been conducted with a wide variety of populations, in different settings and within all subject areas related to the programs. As such, the volume of research on DI is expansive. The National Institute for Direct Instruction (NIFDI) makes this extensive research base more accessible to educators and researchers through a free online searchable database of over 200 entries.

In an article dramatically titled, "The Death of Preschool," in the November/December 2011 issue of Scientific American Mind, Paul Tullis attempts to establish a link between "direct instruction" and a host of psychological and physical ailments that preschool children may suffer later in life due to "toxic stress". Without clearly establishing what he means by "direct instruction," Tullis makes the claim that "early exposure to academics" has the potential "to psychologically damage developing brains," and can lead to physical health problems, including (but presumably not limited to) "depression, anxiety disorders--even cardiovascular disease and diabetes." Damage to the hippocampus is evidently a likely outcome if a child learns the names of different types of whales in preschool, according to Tullis.
Dr. Kurt Engelmann responds to Mr. Tullis' article in his letter to the Editor of Scientific American Mind.

How to Ensure Success
Do you know how to ensure that your school's DI implementation is successful?
The services and implementation materials provided by the National Institute for Direct Instruction (NIFDI) provide schools and districts with a strong basis for implementing the comprehensive Direct Instruction (DI) model successfully with all children. However, a successful implementation requires much more than the services NIFDI provides. What a school does with the services makes the biggest difference.
