A problem, however well designed, does not teach itself.
A new group does not automatically form a learning community.
“ If teaching with PBL were as simple as presenting the learners with a ‘problem’ and students could be relied upon to work consistently at a high level of cognitive self-monitoring and self-regulation, then many teachers would be taking early retirement.” (Savery, 2006 p. 15)
“ It would be naïve to believe that the medical school model of PBL could be imported into other settings without considering how to adapt it to the local context, goals, and developmental level of learners” (Hmelo-Silver, 2004 p. 260).
Need for new research in facilitation
The group and tutorial process remains to be a “ black box .” (Hak & Maguire, 2000 p.769)
