Direct instruction

Direct instruction (DI) is the explicit teaching of a skill-set using lectures or demonstrations of the material to students. A particular subset, denoted by capitalization as Direct Instruction, refers to the approach developed by Siegfried Engelmann and Wesley C. Becker that was first implemented in the 1960s. DI teaches by explicit instruction, in contrast to exploratory models such as inquiry-based learning. DI includes tutorials, participatory laboratory classes, discussion, recitation, seminars, workshops, observation, active learning, practicum, or internships. Model includes "I do" (instructor), "We do" (instructor and student/s), "You do" (student practices on their own with instructor monitoring). DI relies on a systematic and scripted curriculum, delivered by highly trained instructors. On the premise that all students can learn and all teachers successfully teach if given effective training in specific techniques, teachers may be evaluated based on measurable student learning. In some special education programs, direct instruction is used in resource rooms, when teachers assist with homework completion and academic remediation. DISTAR was a specific direct instruction model developed by Siegfried Engelmann and Wesley C. Becker. Engelmann and Becker sought to identify teaching methods that would accelerate the progress of historically disadvantaged elementary school students. Direct Instruction was first formally implemented at a preschool program for children from impoverished backgrounds at the University of Illinois (mid-1960s). The team implementing DI consisting of Siegfried Engelmann, Carl Bereiter, and Jean Osborn. The program incorporated short instructional periods usually 20 to 30 minutes a day. The instructional periods focused on language, reading, and math. The children showed vast improvement which led to further development of the approach . When further developing DI, they applied the same principles to create a formal instructional program that included language, reading, and math.
