A Challenge is immediate, actionable and builds excitement.
Choosing and setting up the Challenge is crucial. If it is interesting and sufficiently close to home, pupils will derive personal meaning and feel a sense of accomplishment upon understanding the content, proposing and implementing a Solution.
If the Challenge is too broad or vague, the pupils will struggle. If it is too narrow, they will not be able to experience the self-direction that is required to develop the skills that CBL cultivates.
Challenges should be difficult and have multiple possibilities for Solutions, as well as organized and scaffolded to support the Learners.
