We discuss the results of a research conducted to study the effects of problem-based teaching and learning of Physics on the ability of students in problem solving and in their attitudes and interest towards the subject. First-year university students are involved in the study. We try to answer this basic question: can a problem-based instruction of Physics improve the ability of students in problem solving and does this ability still remain some time after the end of the course?
