Working in groups, students identify what they already know, what they need to know, and how and where to access new information that may lead to resolution of the problem. The role of the instructor (known as the tutor in PBL) is to facilitate learning by supporting, guiding, and monitoring the learning process. The tutor must build students' confidence to take on the problem, and encourage the students, while also stretching their understanding. PBL represents a paradigm shift from traditional teaching and learning philosophy, which is more often lecture-based. The constructs for teaching PBL are very different from traditional classroom/lecture teaching.
One of the primary features of Problem-Based Learning is that it is student-centered. “Student-centered” refers to learning opportunities that are relevant to the students, the goals of which are at least partly determined by the students themselves. This does not mean that the teacher abdicates her authority for making judgments regarding what might be important for students to learn; rather, this feature places partial and explicit responsibility on the students’ shoulders for their own learning. Creating assignments and activities that require student input presumably also increases the likelihood of students being motivated to learn.
