OBJECTIVETo evaluate the theoretical teaching provided to ophthalmology residents in Toulouse during the 2006-2007 academic year using the PowerVote(®) system. PUPILS AND METHOD: This was a prospective study concerning all ophthalmology residents in Toulouse. Classes were given by the house doctors and senior registrars as PowerPoint presentations lasting about 45 min. Just before each lecture, the house doctors took a 5 min test comprising five multiple choice questions. There were two lectures per month on average. One month after the course of lectures ended, the course as a whole was evaluated using the PowerVote(®) tool, on objectives given to the house doctors in advance. The teaching concerned the macula.RESULTSTen residents took part in the final evaluation in 2007. The residents who had given lectures obtained significantly better results, not only in the initial test but also in the final one.DISCUSSIONTeaching can take many forms. We evaluated teaching by the students themselves. The more involved a house doctor was in teaching, the better he remembered the lesson.CONCLUSIONGiving a theoretical lecture enables residents to reach a higher level, which is further improved if they are involved in the teaching. The use of PowerVote(®) is an interesting pedagogical tool.
