Online Group Awareness-Supported Peer Assessment Feedback Mechanism Implementation And Its Application

With the collaborative learning based on CSCL is becoming more and more extensive,it has brought great convenience for the learners,which is conducive to improving the learning effect and promoting the occurrence of effective learning.Peer assessment is a way of collaborative learning.It has become an issue in the field of the evaluation in online learning.At present,most online peer assessments are short of validity and lack of feedback,and group awareness is a prerequisite for collaboration,and an effective means to reduce collaborative costs,improve collaborative efficiency and reduce collaborative conflicts in collaborative learning,so online group awareness-supported peer assessment,as a typical learning evaluation method in the information education environment,will become an important direction of educational informatization development.On the basis of relevant learning theories and typical practice cases,this paper adds a text suggestion feedback model to the present visual group awareness feedback model.It makes up for the deficiency what learners' one-sided understanding and understanding of the drawbacks of their own but do not know how to correct the possible situation of single visual group awareness feedback model.Then online group awareness-supported peer assessment feedback mechanism of "Visual Group Awareness Feedback Model + Text Suggestion Feedback Model" is constructed.At the same time,the online group awareness-supported peer assessment system is constructed based on this feedback mechanism.Finally,the feasibility and validity of the design are verified by experiments in this study.And it makes up for the lack of feedback mechanism related research,and provides teaching practice for online peer assessment related research,which is helpful to promote the follow-up research in related fields and disciplines.To verify the availability of this system and the effectiveness of online group awareness-supported peer assessment feedback mechanism,95 students were selected to participate in the experiment.The results shown that(1)the system was accepted by the students.This system can enhance the awareness ability of students in the process of peer assessment and promote the interactive behavior in collaborative learning.(2)And the online group awareness-supported peer assessment feedback mechanism had a positive impact on learners' collaborative learning ability and quantity and quality of peer assessment.The study provides a possibility for further improving the effect of different online group awareness-supported peer assessment feedback mechanisms on learners' collaborative learning and learning performance.
