1.0 INTRODUCTION

One of the sectors which fosters national development is education by ensuring the development of a functional human resource. The institution of strong educational structures leads to a society populated by enlightened people, who can cause positive economic progress and social transformation. A Positive social transformation and its associated economic growth are achieved as the people apply the skills they learned while they were in school. The acquisition of these skills is facilitated by one individual we all 'Teacher'. For this reason, nations seeking economic and social developments need not ignore teachers and their role in national development.

2.0 TEACHER EDUCATION

Ghana has been making deliberate attempts to produce quality teachers for her basic school classrooms. As Benneh (2006) indicated, Ghana's aim of teacher education services is to provide a complete teacher education program through the provision of initial teacher training and in-service training programs, that will produce competent teachers, who will help improve the effectiveness of the teaching and learning that goes on in schools. The Initial teacher education program for Ghana's basic school teachers was offered in Colleges of education services (CoE) only, until quite recently when, University of Education, University of Cape Coast, Central University College and other tertiary institutions joined in. The most striking difference between the programs offered by the other tertiary institution is that while the Universities teach, examine and award certificates to their students, the Colleges of Education offer tuition while the University of Cape Coast, through the Institute of Education, examines and awards certificates. The training programs offered by these institutions are attempts at providing many qualified teachers to teach in the schools. The National Accreditation Board accredits teacher training programs in order to ensure quality.

3.0 DETERMINANTS OF TEACHER QUALITY

Teacher quality has such enormous influence on students' learning. Anyone who has been in the teaching business will agree that teacher quality is central to education services  reform efforts. Priagula, Agam & Solmon (2007) described teacher quality as an important in-school factor that impact significantly on students' learning. Quality teachers have positive impact on the success of students. Where the students have quality and effective teachers the students make learning gains while those with ineffective teachers show declines. With respect to the classroom teacher, teacher quality is a continuous process of doing self-assessment so as to have professional development and a self-renewal, in order to enhance teaching. For the teacher educator, an effective or quality teacher is one who has a good subject-matter and pedagogy knowledge, which the he/she can build upon.

Outstanding teachers possess and exhibit many exemplary qualities. They have the skills, subject matter, and pedagogy to reach every child. They help equip their students with the knowledge and breadth of awareness to make sound and independent judgments. Three determinants of teacher quality will be considered here. They are; pedagogical knowledge, subject-matter content knowledge and experience.

3.1 PEDAGOGICAL CONTENT KNOWLEDGE

Trainees of every profession receive some sort of education services that will give them insight into and prepare them for the task ahead. That of the teacher is called Pedagogical Content Knowledge or Pedagogical Knowledge. Pedagogical Content Knowledge can be described as, knowledge the teachers use in organizing classrooms, delivering the content the students must show mastery over and for managing the students entrusted into their care. Generally speaking, pedagogical knowledge is knowledge the teacher uses to facilitate students' learning. Pedagogical Content Knowledge is in two major forms - teachers' knowledge of the students' pre-conceptions and teachers' knowledge of teaching methodologies. Students come to class with a host of pre-conceptions relating to the things they are learning. The pre-conceptions may or may not be consistent with the actual subject-matter that is delivered. Teachers must have a good idea of both kinds of preconception, in order to help students, replace the inconsistent pre-conceptions or build upon the consistent pre-conceptions to bring about meaningful learning. Teachers must have a repertoire of teaching methodologies for facilitating students' learning. When the methodologies are applied wrongly little or no learning occurs in students. In effect when either of the two is weak, the teacher becomes a bad one because that teacher will not be able to execute his/her responsibility in the vocation he/she has chosen. Due to this during teacher preparation, Pedagogical Content Knowledge is emphasized.

3.2 SUBJECT-MATTER KNOWLEDGE

The goal of teaching is to help learners develop intellectual resources that will enable them participate fully in the main domains of human taught and enquiry. The degree to which the teacher can assist students to learn depends on the subject-matter the teacher possesses. That is to say, teachers' knowledge of subject-matter has influence on their efforts to assist students to learn that subject-matter. If a teacher is ignorant or not well informed he/she cannot do students any good, he/she will rather much harm them. When the teacher conceives knowledge in such a way that it is narrow, or do not have accurate information relating to a particular subject-matter, he/she will pass on these same shallow or inaccurate information to students. This kind of teacher will hardly recognize the consistent pre-conceptions and challenge the misconceptions of students. Such a teacher can introduce misconceptions as he/she uses texts uncritically or inappropriately alter them. It is the teacher's conception of knowledge that shapes the kind of questions he/she asks and the ideas he/she reinforces as well as the sorts of tasks the teacher designs.

4.0 CONCLUSION

Teacher education aims at providing a teacher education program through initial teacher training for teacher trainees, and in-service training for practicing teachers in order to produce knowledgeable and committed teachers for effective teaching and learning. To realize this mission, teacher education programs have been instituted for the training of teachers. These programs differ from one country to another. Even within the same country, there may be different programs training teachers for the same certificate. These alternative programs are created, specially, where there are shortages of teachers, and attempts are being made to train large numbers of teachers at a time. These alternative programs ease the teacher certification requirement, allowing those who under normal circumstances would not become teachers. This introduces serious challenges. Because large numbers of teachers are needed within a short period, their training is somewhat fast-tracked resulting in what is usually referred to as half-baked teachers - teachers of lower quality. Applicants who did not gain admission into the program of their choice come into teaching only because they have nowhere else to go. Such applicants tend not to be dedicated to the teaching service in the end. Fast-tracking initial teacher preparation actually harm the mission for which the initial teacher training institutions were created. This is because the teacher produced through such training are usually not of high quality.
