Problem-based learning combined with project-based learning: A pilot application in digital signal processing

The acronym PBL brings together two different teaching methods: problem-based learning and project-based learning. Problem-based learning methods focus on the acquisition of knowledge and are frequently used in the teaching of law and medicine. However, it is not common to find problem-based methods in use within the area of science, engineering and technology, where knowledge acquisition usually requires a certain hierarchical ordering of the contents. In the area of engineering, the predominant learning methods are clearly project based and tend to be directed towards applications of the knowledge acquired. Here a combination of the two strategies that permits the acquisition of knowledge through problem-based methods and the consolidation and application of that knowledge through project-based methods is presented. We then report on this combination of the two PBL methods as applied in the field of pattern recognition as part of a digital signal processing course within the Electronic Engineering and Telecommunications bachelor's degree at the University of Barcelona.
