As a consequence, if the task parameters change during a learning event—as it is the case in PBL—one would expect that students perceive different levels of autonomy and consequently engage differently. For instance, in PBL during the initial phase of defining the problem, students have to work in teams under the guidance of a tutor. During this phase one could expect that students’ autonomy would be relatively low. However after this, students undertake independent self-study, during which one could expect that their autonomy would be relatively higher and thus they would be more cognitively engaged. After this, students converge and share their findings, which would result again in a decrease of autonomy and cognitive engagement.
