Authentic learning in history

What is an authentic problem in world history? My colleagues and I grappled with this question when we set about to design a problem-based learning (PBL) class for AP World History. We looked enviously at some of our peer disciplines such as biology which we imagined having clear problems for students to work on (they didn't, but that is another blog post).

We consulted a number of sources in research. What did the College Board say? What do the state standards say? We reached out to Walter Parker, the social studies methods instructor at the University of Washington School of Education, to help us clarify our thinking. (Robert Hallock at Edutopia)
