[Strategy] Compacting [Definition] Compacting is the process of adjusting instruction to account for prior student mastery of learning objectives. Compacting involves a three-step process: (1) assess the student to determine his/her level of knowledge on the material to be studied and determine what he/she still needs to master; (2) create plans for what the student needs to know, and excuse the student from studying what he/she already knows; and (3) create plans for freed-up time to be spent in enriched or accelerated study. [Example] Rather than receiving additional direct instruction on writing a five-sentence paragraph, a student who already has that skill is asked to apply it to a variety of topics and is given instruction on writing a five-paragraph essay.
