Based on the REBUT (Renovation of Evidence-Based University Teaching) strategy, this paper addresses the didactic problem of the educational renewal of teaching/learning regarding university teaching staff for undergraduate physics programs. The support strategy and pedagogical innovation of REBUT is based on the collection of evidence on the specific deficiencies in the teaching/learning of a particular teacher, and can be relatively easily documented whilst running simultaneously with the development of the course. Whilst the evidence is collected, it is analyzed -together with the teacherand the data is evaluated throughout a whole semester, then, a specific plan of innovation is proposed, implemented and evaluated in subsequent semesters. The steps and ingredients of the collection of evidence are described, some of the evidence collected is discussed, and elements of pedagogical innovation are proposed, taking into account the existing institutional guidelines.
