A Path of Endogenous Teacher Professional Development—Perspective of Brentano’s Value Philosophy

From the point of view of logic rationality, the traditional philosophy of rationality emphasizes the purpose and means of cognition, but rejects the meaning and practice of life, and its thought also profoundly affects the development of teachers. The requirement of teacher’s professional development under the modern educational concept highlights the teacher’s subjectivity and personality traits. Brentano’s value philosophy is a philosophy that respects the tradition of life practice. Its intentional theory, insight life meaning, and strong practical purport provides a new path of thinking dimension for clarify the value orientation of teacher professional development and break through the current situation of teachers’ professional development, which lead a path of “endogenous” teacher professional development that based on the construction of teachers’ personal knowledge from the teacher’s self-evident feelings and belief, and then from the teacher’s individual professional development to teacher’s collective professional development.
