For a start, I thought the display of student work in itself could be more productive. So we grabbed examples of responses for the current assessment in each year level and annotated them. The annotations highlight where the students have addressed the task requirements and where they have missed them. The annotated responses were then posted onto the walls around the room.
Winner. Every student used these in the lessons today, with the majority of them taking pictures on their phones and tablets.
So I encourage you, use the walls.
