The document discusses team teaching, which involves two or more teachers working together in the same classroom. It defines team teaching as having multiple teachers present who cooperate strongly with each other and students. This allows for differentiation of instruction and a higher focus on individual pupils. The benefits of team teaching include addressing growing student differences, reducing large class sizes, providing relief for teachers, and allowing more individual attention. However, team teaching is also expensive, demands high collaboration between teachers, and requires compatible personalities. Different forms of team teaching include teaching one subject, multiple subjects, or mixed age groups.
