Developing and Assessing Teaching Effectiveness

Who is an effective teacher? It isn't possible to give a single answer to this question because defining a teacher isn't a simple question. Many studies have demonstrated that an effective teacher can have an enriching effect on the daily lives of children and their lifelong educational and career aspirations and can also have a direct influence in enhancing student learning. That's why it isn't possible to define an effective teacher only referring to their students' grades; the question is much more complex; as a matter of fact we can say that it has a multi-dimension character. Starting from this point of view it's important to define the suitable methods/instruments of a teacher's evaluation and capability.
