PBL questions are primarily used at the start of a new problem your students are seeking to solve. They help students think deeply about the problem while helping them to frame the research they will undertake.
The best questions cover pre existing knowledge, help clarify the process to be undertaken, and identify the overall goals of the PBL. There is a host of research (Slavey and Duffy, 1995; Nilson,2010; Duch, B.et.al, 2001) examining the benefits of PBL for students that range both individual (self awareness, self management, critical thinking) and collective (team work, empathy).
Use a word cloud to show student responses to the class.
