The PER Canon
At the 2005 FFPER, a subgroup of attendees met to develop a canon intended as a resource for new graduate students, faculty members entering the field, or by physics educators who wish to familiarize themselves with seminal and exemplary research and curriculum development in PER.
Links to the articles are available at the PER Canon Compendium.
Additionally, information on how the Canon was assembled was published in the Fall 2005 APS FEd Newsletter.
In 2011, a group tasked with updating the PER canon developed an expanded list of selected readings for PER.
