What the move is
Switching the frame means describing the same situation as a different kind of problem and seeing what the new description asks you to do. The situation stays fixed. The question changes. Restated as a systems problem, the Secondary 1 afternoon is about what the time is taken from. Restated as a design problem, it is about what students will do with it.
You write one sentence per way of thinking, four minutes each, and you write them badly on purpose. The aim is to break the sense that there was only ever one way to describe the situation. Finding the right restatement comes later.
The idea behind it
Kees Dorst studied how expert designers handle problems that resist solution. He found they rarely solve the problem as given. They create a new frame, a different way of describing the situation, and the new frame makes a solution possible. He calls this frame creation, and argues it is the part of design practice most worth carrying into other fields.
Gareth Morgan made the same point about organisations. Describe a school as a machine, an organism or a political system and you will see different problems and reach for different fixes. None is the true description. Each is a lens, and switching lenses is a discipline that can be practised.
Why it works
The test that matters is the first action. A restatement that leads to the same first step as the original adds vocabulary and nothing else. A restatement that changes what you would do on Monday has found something the original frame was hiding. That gives the group a plain way to choose between restatements without arguing about which is truer.
It is also the cheapest move in the strand. Forty-five minutes of one-sentence restatements costs less than a single week of a plan built on the wrong problem.
