Online Argumentative Learning Activity Design For College Students Under Knowledge Building Theory

Argumentative Learning refers to the learners elaborate their own views and challenge other people on the ill-structured topics in argumentative way so as to improve their views and deepen the understanding of knowledge.And the online argumentative learning platform provides a technical environment for this learning style,which includes recording the learner's views,facilitating collaboration.And also scaffolding can be designed and be utilized on the platform in order to help learners perform better in learning activities.The paper first introduced the theoretical basis of argumentation theory and knowledge building theory,and sorted out the present studies about argumentative learning activity at home and abroad.And then from the first four principles of KB 12 principles,namely "Real Ideas and Authentic Problems","Improvable Ideas","Idea Diversity" and "Rise Above",design argumentative learning activity strategies in aspects of topic,view elaboration,and demonstration process.The final research results show that(1)in topic design strategies,the"competition theory" strategy can stimulate students to find support theory,and the"problem situation" strategy can promote learners to check the details,and the"dilemma" is more likely to promote learners to think deeply about the nature of the problem,(2)in elaborating strategies,the setting of scaffolding may affect the confrontation of their views,and let the rationality of the argument become the focus,(3)in demonstration process strategies,combining "as a group" and "assume role's task" strategies can significantly improve the learner's interaction and perspective improvement.
