This intervention program was designed for students who are resistive to the previous intervention packages, requires intensive one on one instruction, and guides students through a 3 part instructional sequence. Section 1 incorporates errorless learning using demonstration, cueing, and immediate feedback, section 2 uses pacing procedures with immediate feedback for each problem and section 3 uses explicit timing to build fluency and ensure maintenance. The Student moves through a pre-determined sequence of skills and progresses across these as mastery criteria are met. Item set sizes (i.e., number of problems taught at one time) are sequenced and controlled and practice opportunities are provided to promote generalization.
