The role theory of reflective teachers in developing educational and professional practices in the classroom.

        [A study/discussion/commentary/reflections on Donald's Schon approach. ]

        The contribution that Donald Schon has made to the development of educational thinking:       An analysys of the "reflective teachers" theory and it´s role in the classroom.

      Are just tentatively hunches of mine, as an English student (so I see gramatically here), not that academical then.  Hence, let´s wait further comments to back it up. Or not.

     "THE MEANING" (slightly) hints that you want to re-explain his conceptual frame of mind, which perhaps you don´t.      You rather want to discuss his role into the development of teaching.

       Also, your tutor (for lack of a better word) may think you are kinda "showing off" intellectually, you are a student for the time being.  Or it seems so, then you have to be bit more humble.

       "Donald Schön's concept or Donald Schon's model" are valid grammatically speaking, don´t know if it fits into the given context, tough.
