Some subscribers to Phys-L might be interested in a discussion-list post "Re: The Karlsruhe Physics Course and The German Physical Society" [Hake (2014)]. The abstract reads:
*******************************************
ABSTRACT: Corrado Agnes, in his PhysLrnR post "The Karlsruhe Physics Course and The German Physical Society" <http://bit.ly/S6AKbt>, wrote (paraphrasing): "Bad News for Physics Education Research and Teaching. I want to inform you of an amazing and almost unbelievable attack made by the German Physical Society (GPS) against a group of teachers and researchers in physics education, whose only guilt is to teach physics according to the approach of the Karlsruhe Physics Course (KPC). . . . . The basic ideas of the course were explained in 'An up-to-date approach to physics' [Schmid (1984)] <http://bit.ly/1w5fGSG> and 'The Karlsruhe Physics Course' [Herrmann (2000)] at <http://bit.ly/RpLeSz>."
Herrmann pointed out that KPC mechanics is based on the interpretation of forces as momentum currents as made by Max Planck (1908) <http://bit.ly/1ihA2yy> and Andrea diSessa (1980) <http://bit.ly/1oj8MqY>. KPC documents are at KPC (2014) <http://bit.ly/1kfI5AA>.
