**3.3 Availability of different communication networks and national optic fiber**

The availability of different communication networks and the national optic fiber provide another great opportunity for the enhancement of teacher professional development in Tanzania. Teachers, wherever they are, can now get connected through different communication networks and participate in self-directed teacher professional development. Also, the presence of the national optic fiber provides an opportunity for Internet connectivity in schools—through which teachers can search for, and share, learning materials, which can be used to enhance their knowledge, skills, and competences. What is needed, therefore, is the creation of conducive environment for self-directed teacher professional development to take place. This could be done through the construction of supportive infrastructure and provision of computers and gadgets in schools.
