We experienced this method at the visit of Bourgas, Bulgaria. The lesson was about the topic ” Migration in Europe”.  Stdents were split into international teams and had the task to discuss and draw conclusions on certain questions. We experienced team building, discussions, integration, creativity, searching information on the internet, developing strategies together, design an action plan within a short time, provide feedback on proposals that have already been prepared and, where appropriate, to develop suggestions for improvement and in the context of project evaluations or collection of intermediate results. Students enjoyed very much while working in groups, shared opinions, improved their knowledge on the migration issues, practiced their English, gave many new ideas, criticised and gave their creative proposalls on the solution of the problems arisen by the migration movement.
