A teacher is expected to have a total commitment in giving the children the type of education that trains them to growth and development. A teacher is a person who is qualified in every way as a professional teacher to teach in schools especially in his/her area of specialization. A teacher’s personality type should be divergent, enduring and stable enough to help learners solve their problems. No educational system can be stronger than the caliber of the teaching staff.
The main focus of the implementation of the curriculum is the learner, while the most important person in curriculum implementation is the teacher. (Obasi, Adaobi & Ajeka, 2007). The teacher is the prime mover of the educational system. Aghanta (1991) conceptualizes that as an input operator into the educational system, the teacher plays a major role in the conversion of raw materials particularly students into finished products e.g. graduates.
Knowledge of educational aims and contexts. The aims and objectives of education vary from societies based on the problems and needs of the society. The teacher needs to be grounded in the historical, philosophical, sociological and other issues the society is experiencing and how education can be used in solving them.
Knowledge and characteristics of the learner: A good teacher should understand how children learn and develop. He/she should be able to provide learning opportunities that supports their intellectual, social and personal development. Education revolves around the learner; a learner who has acquired a sound education should be able to contribute to the solutions of problems in society.
Knowledge of curriculum: The teacher here should understand and have the knowledge of the subject matter, delivery methods and knowledge of evaluation methods.
The Humanistic standards of a teacher deals with his/her personality traits, such as: his/her sense of responsibility, amiability, initiative, sincerity, self-control, loyalty, physical strength, leadership qualities and be good personality, decisiveness, likes fun and a sense of humour, punctual, co-operates with colleagues and be committed to self improvement amongst others. All these will help the teacher to succeed in the varied task he/she must perform.
Finally, success in the discharge of the duty of a teacher depends to a large extent on the degree to which teachers possess the necessary cognitive, affective & psychomotor skills. Therefore, the teacher should have the appropriate knowledge, attitude & physical skills to carry out whatever activities he/she is expected to engage in, to help learners acquire desired knowledge and skills to bring about changes.
