Purpose of the Study Researches have been made relating teacher′s effectiveness measurement. However, they share a common defect that they have been done on the basis of superficial aspects of the problems aspects that can bi measured by general objective survey only, but this study is designed "to understand his behavior in terms of a human behaving and of a self as an instrument"-principle, based upon the Perceptual Psychology which puts more stress on the inner perception than on the external one.
