In the weekly team meetings, teachers discuss important topics for the forthcoming week and develop the subject matter, materials and methods to be used. It is worth noting that, in education, small is not always preferable to large. Large groups of students may sometimes be taught together in lecture mode and then broken down into smaller groups for other styles of teaching. This adds flexibility to the class schedule and allows teachers to split students into groups in any way that suits their needs, such as for parallel or differentiated instruction. It also allows them to run cross-disciplinary sessions, such as an enquiry facilitated by a science teacher and a media teacher.
