CREF IN THE CLASSROOM: PROBLEM-BASED LEARNING IN THE PHYSICS TEACHING
The traditional teaching of physics applied in schools is based mainly on the transmission of knowledge and the exhaustive resolution of textbook exercises or entrance exams. This work presents the CREF (Centro de Referência em Ensino de Física – IF/UFRGS) online portal, which is a great website with many open, thought-provoking and motivating questions for teaching physics. In its application, the active methodology of Problem-Based Learning (PBL) was used, where the student is presented with a real problem situation in his daily life in which he must solve it, identifying the knowledge he already knew on the subject, raising hypotheses, researching about new knowledge, investigating and working in groups and being tutored by the teacher. Selected questions from CREF site, adapted for the classroom, are discussed using the PBL methodology. The dissertation describes in detail this dynamical process and, as a result, presents an educational material and its application in the virtual classroom, as a suggestion for use by the teacher interested in differentiated strategies to his practice.
