Perceptions of students after implementing peer instruction in an introductory physics course

In the present work we carried out a qualitative educational research to assess the perceptions of a group of students that attended (weekly and non-mandatory) complementary classes of a physics course during 2017. In these classes the teaching method called peer instruction (PI) was implemented, which involves collaborative learning among students. From the students' responses to a simple questionnaire we assessed some basic aspects of these classes from which we can conclude that, in the first place, students considered that PI had positively influenced their comprehension of physical concepts and that, secondly, they positively valued the activities performed and the dynamics of these classes. These results, which are part of a series of previous works that have been published elsewhere, are relevant in a context were active and collaborative learning strategies are practically non-existent and push us to continue and broaden the implementation of this and other active learning methods in physics courses.
