In order to improve student learning in an advanced course in aeronautics, lectures are replaced with more student-centred sessions based on peer learning. The course is organised in student teams, with the main task of delivering lecture requests for full class discussions. For the same reason, the written theory exam is replaced by a peer review of student reports. The new approach is found to result in a substantial increase of student-student and student-teacher interaction, leading to observable improvements in the course results. Finally, some feedback from the students is presented, being in great favour of the peer learning approach. (Contains 1 figure.)
