Market requirements and competition in the job market set the necessity for an engineering specialist capable of not only analysing the theory of a situation but also able to transfer theoretical knowledge into practise. In order to lessen the degree to which students are isolated from those real-life situations with which they will be working with daily upon graduating, it is important to integrate a problem-based learning approach based on the study course. The paper describes a Cooperative Problem-Based Learning Approach used in Environmental Engineering Studies and provides progress analysis about 8 years of experience in organizing the course.
