This book is concerned with social networking in teacher education, the impact of social networking on pre-service English language teachers’ metacognitive awareness and why social networking should be integrated into teacher education. Pre-service teacher education has a double role to play in fostering learner autonomy among student teachers and in encouraging them to take the first steps towards autonomy by fostering metacognitive awareness. Nevertheless, there is little research on this issue in the relevant literature. In this regard, pre-service English teachers’ metacognitive awareness may be enhanced through social networking, which may promote professional knowledge development, professional growth, reflective thinking, and more importantly teaching awareness. Social networking can provide the missing piece by offering student teachers great opportunities to reflect upon their learning/teaching processes making them more effective teachers.
