In the implementation of problem-based learning (PBL) programmes, increased
attention is being paid to the role of teachers as tutors. The put-pose of
this article is to describe the different stages of the tutors' evaluation
process within a single discipline using a PBL programme, and to present t
he results of their performance evaluation in two academic years. A checkli
st (with items corresponding to the tutor's tasks in PBL) was applied. This
tool was considered both by students and by tutors as an excellent formati
ve instrument and an essential framework for monitoring and assessing the p
edagogical process. Moreover, the findings of this study confirm the existe
nce of different tutoring styles valued by the students and also the import
ance of continuous feedback in the improvement of the teachers' pedagogical
performances.
