Constructivism　takes　learning　as　the　initiative　constructive　activity　of　learners　based　on　their　own　knowledge　and　experience.　During　the　course　teaching,　for　constructing　knowledge　better　during　the　procedure　of　collaborative　learning,　the　premise　is　that　learners　should　have　their　own　relate　knowledge.　This　paper　puts　forward　a　dynamic　collaborative　learning　oriented　knowledge　model,　which　includes　the　construction　of　the　knowledge　model　and　the　partition　of　the　field　knowledge,　the　control　strategy　of　the　learning　process　is　also　put　forward.　©　2011　IEEE.
