The lifebuoy is intended to support the process of the tutorial in its initial phases, just like a swim ring when learning to swim. When you know how to swim, you don’t need a swim ring. The lifebuoy is an aid to establishing a common way of working with problem-solving, learning and collaboration in the tutorial group. The lifebuoy consists of core questions that the students pose in order to create a systematic way of working in the scenario. The processing is also dynamic, which means that it may be necessary to move between the core questions several times during the process.
