The paper addressesthe 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 andresearch.Then summaryof the 3RolesPlaying methodwhich satisfies goals of both of them is presented. Results of an experimentthat took placein theTechnical University of Gdatisk, Poland in the summer semesterof 1997/98 are described, and verification of the resultsvalue is made. Keywords Experiments in software engineering, project-basededucation, quality assurance,object-orientedmeasurement.
