Collaboration between lead practitioners and teachers is a powerful professional development activity that can help teachers improve their subject knowledge, think about teaching strategies in different ways and learn new ideas to try in the classroom.
In fact, teachers have been found to learn more from each other than with mentors or in traditional classes and workshops. Even better news is that teachers using collaborative practices are more innovative in the classroom, hold stronger self-efficacy beliefs, and have higher job satisfaction (The Teaching and Learning International Survey—TALIS 2013)
