Laboratory experiment with the 3RolesPlaying method

The paper addresses the problem of making experiments for software engineering during laboratories. There is a need for experimental investigations. If experiments are performed in the lab together with training they must also have high educational value. In the paper, there is discussion about joining education and research. Then summary of the 3RolesPlaying method which satisfies goals of both of them is presented. Results of an experiment that took place in the Technical University of Gdansk, Poland in the summer semester of 1997/98 are described, and verification of the results value is made.
