First things first, let me introduce to you what a CHALLENGE BOX is:
The concept Challenge Box has been adopted as an English translation of Caixes de Propostes in catalan.
This learning strategy consists in presenting to a group of students (2 or 3 students) a challenge inside a box. The students have 5 hours to solve the challenge (1 hour per day).
The challenges can be varied, but they have to include concepts and skills from different areas. They have to be multidisciplinary. As you can imagine, an English Challenge Box uses English as the working language.
In the Challenge Boxes, students are expected to work autonomously and to collaborate the work.
