The purpose of this study is to analyze and suggest how the teacher evaluation should be changed
to fulfill the rationality of Habermas's communicative action. The current teacher evaluation has failed
to solve the validity of the claims of the evaluators, such as the students and their parents, which is
the Achilles' heel of the evaluation, by disregarding the rationality of the communicative action.
Thereby, the teacher evaluation has inherently embedded the critical problem of the validity.
Moreover, the teacher evaluation faces the limitations that it cannot stimulate the rational motive of
the teachers in improving their teaching and cannot activate the potential of duty formation in
teachers towards teaching the students, which is built upon mutual understanding and consensus
between them.
It is imperative to establish the dialogical relations between the communicative subjects and to
improve teaching through mutual understanding, if the students' evaluation of the teaching is to be
educational interaction rather than organizational behavior. It would be best if the teaching is
improved through mutual understanding-oriented relationships rather than through evaluating
relationships, such as those between observers and observed teachers, and if change can
simultaneously occur within the students for them to actively participate in their learning. If the
rationality of the communicative action is agreed upon, the transformation of the framework of the
teacher evaluation should be made possible through government's policy.
