With the integration of English at university teaching, there are several aspects to improve, to emphasize, to integrate... For example, we have observed that there are a certain distance between students and teachers when using a foreign language due to a lack of practice and self-confidence. To bring the student into English and also, to improve this self-confidence, it is necessary to find strategies to integrate the fact of speaking English into the class, and get student expressing in English. From this point of view, in the subject of Sistemes Elèctrics de Potència we propose a specific activity in order to improve not only the interventions in the class, but also the oral exposition of projects. At the same time, we shall deal with other generic competences as the oral communication and the use of information resources. Then, we propose an English papers research activity about the topics given in class. Then, students have to choose one of these papers and summarize it in English. From this paper and the summary, the student has to prepare an oral exposition to explain the work done. Here we are going to expose all the material and process that we have followed to prepare and develop this activity and also the results that we have obtained.
