The technique of scaffolding and the use of levels in games provides visual progress to the student and maintain interest in the instruction as the student moves from level to level having different experiences and achieving success as they progress toward the ultimate goal. In gamification, the levels usually become more difficult and challenging as the student moves toward the end and the skills they exhibit at the final level would not be possible without the experience of playing the preceding levels. This idea is embodied in Merrill’s application principle that “instruction should provide coaching, which should be gradually withdrawn to enhance application” (Merrill, 2009, pp. 42).
