The article investigates the issue of teaching evaluation in higher education, providing a picture of the phenomenon into the Italian specific context within a European dimension. Starting from the premise that in Italian universities, teaching evaluation is based on general indicators which reflect a simplification of a complex phenomenon, scientific research related to teaching evaluation in higher education is presented and discussed. In this perspective, it will be argued that nature of teaching evaluation is characterized by multidimensionality and complexity. Only in this way it can represent a useful instrument for the improvement of teaching process and for the comprehension of the importance of being effective teachers. Moreover, on the basis of a participative model, it seems important to involve teachers and students in the formulation of relevant questions related to teaching. The aim of the research is represented by highlighting the specific aspects of teaching process dependent from the context through a comparison among faculties. Seventy interviews have been carried out with teachers and students of the same four faculties (Humanities, Psychology, Educational Sciences, Mathematics and Natural Sciences). Qualitative analysis of the data collected are conducted using the scientific software Atlas.ti. The outcomes confirm our initial assumptions showing differences among the four faculties considering the multiple dimensions of the university teaching.
