| With the continuous advancement of education informatization,blended learning that can combine the advantages of online and offline learning has attracted more and more attention.At the same time,the new curriculum reform also clearly proposes to establish a teaching with multiple evaluation indicators and multiple evaluation methods.Evaluation method,the traditional teaching evaluation method with teachers as the main body and summative evaluation as the main body can no longer adapt to the new curriculum reform.Peer evaluation as a formative evaluation strategy has begun to be widely used in blended teaching.The design of peer evaluation activities in a blended learning environment will have a profound impact on blended learning.This research aims to build a framework for peer evaluation activities in a blended learning environment based on the existing peer-evaluation activity model,combined with the characteristics and advantages of the blended learning environment,and rely on the "Modern Educational Technology Principles" course for teaching practice.To test its effectiveness,continuously improve the framework of peer evaluation activities during the implementation of mutual evaluation activities,increase the effectiveness of the framework of mutual evaluation activities,enrich the teaching evaluation methods of blended learning,improve the quality of blended learning and better develop peer-to-peer interaction in the blended learning environment for teachers.Based on the analysis of domestic and foreign mixed learning and peer review related research,this research is guided by the constructivist learning theory,the nearest development area theory,the developmental evaluation theory and the cooperative learning theory,using literature research methods and design-based research,Social network analysis method,content analysis method and survey method to carry out research.First,use the literature research method to sort out the research status of blended learning and peer review,master the existing peer review activity model,and then combine the particularity of this research to construct a peer review activity framework for blended learning environment,relying on "Modern Education Technology Principles" course,carried out three rounds of peer evaluation activities research to explore the effectiveness of the activity framework,which was specifically tested from the following four aspects:(1)Interaction density and centrality of learners’ participation in mutual evaluation activities(2)The depth of interaction of the content of the learner’s participation in peer evaluation activities(3)the degree of participation of learners in peer evaluation activities(4)the homework scores of learners’ participation in peer evaluation activities.Through the teaching practice of three rounds of peer evaluation activities,this study draws the following conclusions:(1)This study Constructed a framework of peer evaluation activities in a blended learning environment(2)The framework of peer evaluation activities in a blended learning environment constructed by this study is effective(3)The anonymous evaluation method in peer evaluation activities is helpful To improve the effectiveness of mutual evaluation activities(4)Teachers’ participation in peer evaluation activities helps to improve the effectiveness of mutual evaluation activities. |
