Problem Based Learning (PBL) has been used in the teaching of different scientific areas and the obtained results show that it helps in the learning as well as in the development of a number of important skills and abilities. We take into account the PBL principles and the curriculum of the Physics I course to design three PBL didactic sequences to help the conceptual learning and the development of problem-solving abilities. These sequences were explained in the Physics I course of the curriculum of two High Schools at the México State. In each High School we have two experimental groups and one control group. The effectiveness of PBL teaching sequences was evaluated with the Force Concept Inventory (FCI). Our results show that: PBL is a teaching method more effective than the traditional method, PBL promotes: the active participation of the students, critical analysis and resolution of problems arising in Physics, the interaction among the students, as well as autonomous learning
