Instructional explanation
An instructional explanation is part of an instructional process wherein an agent, other than the student, provides an explanation for the student to comprehend. Instructional explanations contain the target knowledge components, which is the goal of the instruction.
Studies using instructional explanations manipulate their presence or absence (Schworm & Renkl, 2006), or how completely they are justified Hausmann & VanLehn, 2006.
