Teacher Professional Development
As with the development of human capital in business, the productivity of education can be
significantly improved by upgrading the skills and knowledge of teachers and their ability to
apply these in the classroom. Educational researchers have identified two kinds of teacher
knowledge that can significantly improve their practice: their understanding of their subject
matter and the pedagogical knowledge about how students learn the subject and how it is best
taught (Darling-Hammond, 1997; Shulman, 1986).
