Research On The Design Of Blended Collaborative Learning Activities Oriented To The Generation Of Collective Intelligence

With the continuous integration of information technology and education and teaching,blended learning has become the main form of university teaching,and collaborative learning is an important organizational form of university teaching,so blended collaborative learning has become a new research trend.Research shows that collective intelligence refers to the wisdom of the crowd generated by individuals in the process of team collaboration,and its generation level is the key to measuring the quality of blended collaborative learning.Therefore,this research focuses on the core question of "how to effectively design blended collaborative learning activities and promote the generation of collective intelligence".This research as a whole is a design-based study,which takes graduate students majoring in educational technology and modern educational technology in a university as the research object,and takes the professional course of "Online Curriculum Development" as the practice field.The research process is as follows:firstly,based on collaborative knowledge construction,the paper clarifies the principle of collective intelligence generation,that is,the four stages of "information sharing,interactive conflict,negotiation and summary,and creation and generation",and develops a blended collaborative learning activity model and curriculum model for collective intelligence generation by determining activity principles,analyzing activity elements,building activity frameworks,and designing evaluation methods.Secondly,the activity framework of activity introduction,activity implementation and activity evaluation is studied to put the blended collaborative learning activity model and curriculum model generated for collective intelligence into practice,and the strategy improvement is carried out in the two rounds of activity practice to improve the activity model and curriculum model.Finally,the effectiveness of the design of blended collaborative learning activities and the promotion degree of collective intelligence generation are analyzed from three dimensions: collective intelligence generation level,group collaboration dialogue coding and group collaboration performance level.The results show that the blended collaborative learning activities designed for collective intelligence generation in this study are reasonable and effective,and learners generate collective intelligence in a series of blended collaborative learning activities.This research will provide a reference for the deep integration of information technology and education and teaching,and answer questions such as how to promote the improvement of learners’ innovation ability and collaboration ability according to the law of collective intelligence generation.
