Instructional Design and Practice of Problem-Based Collaborative Knowledge Building under Network Environment

摘要

A new hybrid learning model of problem-based collaborative knowledge building (referred to as the CKB) is based on the specific learning CKB under network environment. It can be integrated with knowledge creation to promote advanced cognitive activities and to solve problem together. We expound its connotation, basic elements, characteristics, and explore the main steps and operation process. The model has three main stages including learner community, cognitive conflict-based and integration-based CKB. Taking "structural chemistry" course as an experiment to verify, though action research, questionnaire survey and the interview method, it proves that the model plays active roles in improving student's learning interest, academic performance and high levels abilities, especially social abilities, ability to practice, research and to solve problem in real situations. It is important to take into account whether the teachers have the ability required by the model.
