Introduction
When we talk of philosophy of education in ordinary discussion, they often mean the personal view of what the schools should be doing or their own attitude to the educational system. In trying to criticize what they find as faculty in a given system, they refer to their own supposed more adequate philosophy. In this way, everyone is his own philosopher of education.
The professional philosopher of education is in a position to provide a thorough and hard look at the educational system, to analyze it, and after deep reflection, to produce an alternative system. Both process of analysis and reflection and the product of their reflection are what the professionals mean by philosophy of education.
Educational philosophy attempts to comprehend education in its totality and tries to interpreter it by means of general concepts that will guide our aims and policies of education.

The Relevance of Philosophy of Education in a Teacher Training Institute.  

Since philosophy involves personal critical thinking, rather than taking statements and recommendations from others for granted. In this way, it helps the teacher become more aware of the implications of the various issues involved in education. By engaging in thinking on the subject himself, he discovers other dimensions which other educations have neglected. He discovers for himself the limits, which formulas and conventional wisdom have in educational issues.  
Secondly, philosophy gives more weight to validity or soundness of an argument rather than to the authority of the person arguing the case, it encouraged the teacher to look at educational problems critically, clearing them of the confusions that personal interests prejudices and emotional usually introduce to educational discussions.
Again, philosophy has a humbling effect on those who pursue it, in that it forces one to keep an open mind on any subject, since new evidence may render one’s previous opinion less tenable. This is for and dogmatic on educational matters.      
The hallmark of a scholar is humility. Socrates, the father of philosophy asserted that, “it is not what wise men say that constitutes wisdom, rather the beginning of wisdom is when one knows how ignorant he/she is”. This humble attribute enables us to keep on learning even from our students and stop us from arrogating all knowledge and wisdom to ourselves.
Thirdly, it increase the ability of the teacher to influence educational policies under which he operates, since by engaging in theoretical discussion of educational issues, he himself can offer alternative for action. He will no longer be at the receiving end of the educational policies formulated by others. He will now be cooperating with others to formulate more adequate policies, which he will implement in the classroom. As it were, any educational policy formulated will be implemented by the teacher, but he is never part of the policy. Many policies suffer poor implementation because the implementers have not been part and parcel of the policy formulation.
Philosophy of education offers personal intellectual education to the teacher. The teacher needs this type of education more than any one else. A teacher can never truly teach unless he is still learning. In this regard, Akinpelu (1981) Quotes Rahindranath Tagore assaying: “A lamp can never light another lamp unless it continues to burn its own flames”. This means that a teacher needs to continues to develop himself intellectually if he will assist in the intellectual development of his students.
The study of philosophy of education enables teachers to appraise their progress and short comings against the background of the aims and objectives of an educational programme.
Finally, philosophy of education helps in the development of a critical mind in the teacher and promotes same in their students.
