Capacity building in the sciences: imperatives for teacher education in Nigeria
It is a truism that we now live in the modern age of science and technology. To participate in that world and derive benefits from it, every nation requires the relevant manpower. According to Nigeria's National Manpower Board (2000), "manpower is the most important ingredient of the development process". For optimum national development, every nation requires various categories of manpower, including artists, social scientists, lawyers, journalists, accountants, scientists, technologists, engineers, medical doctors, agriculturists, teachers. researchers, etc. Teachers; who are the products of teacher education, are responsible for producing these different categories of manpower through the process of teaching. The teacher is the main catalyst for educational productivity in any nation. Hence, the importance of the teacher in national development is well recognised by Government. It is emphasised in the National Policy on Education (1977, reprinted 1998) that "education in Nigeria is an instrument 'par excellence' for effecting national development" (p. 5) and that "no education system can rise above the quality of its teachers" (p. 33).
