“…Direct Instruction is characterized by clear presentation of academic content, sequenced component and sub-component skills, teacher directed instruction, high rates of opportunities to respond (OTRs), systematic review of content, systematic feedback, initial and ongoing assessment, and learning concepts and skills to mastery (Becker & Gersten, 1982;Carnine, Silbert, Kame'enui, & Tarver, 2004). The DI process can be simply summarized as a model -lead -test sequence of instruction in which the teacher first explicitly models, then leads students through guided practice, and finally assesses student knowledge through more independent and authentic activity (Simonsen, Fairbanks, Briesch, Myers, & Sugai, 2008).…”
