Problem-based learning uses an inquiry model. Students start with a given problem, make a plan for gathering information, pose new questions and summarize their research by presenting their conclusions (Duch, Delisle, Hoffman and Ritchie, Stepian and Gallacher cited in (Schneiderman et al., 1998)). In this case, the driving force is the problem given and the success is the solution of it (Vu, Van der Vleuten, & Lacombe, 1998).
