Study On The Quality Of Peer Evaluation And Itsinfluencing Factors In Blended Learning Environment

The research direction of peer evaluation focuses on the effectiveness of peer evaluation and the attitude of teachers and students,but there are few researches on the quality of peer evaluation.Due to the limitation of the college entrance examination system,information technology courses in high school have not been able to be valued by schools,teachers and students.Therefore,less time is allocated to information technology courses compared to other disciplines and students do not pay attention to information technology courses after class.In the process of information technology class needs to be allocated some time to finish the homework to the student and evaluation,limited to the classroom time and energy,and not every student can get the teacher's feedback,so peer evaluation is necessary to make up for the defect.Although the quality of peer evaluation is not high,it can enable most students to get personalized feedback.Therefore,research on improving the quality of peer evaluation is a top priority in the laboratory.The research focuses on the quality of peer evaluation provided by high school information technology students in a mixed learning environment,whether it will change with students' repeated practice,and the influence of various factors on the quality of peer evaluation in different periods.Choose high grade of ordinary high school students as the research object,adopt questionnaire survey and interviews to collect the data of basic attribute,background information,attitude to peer assessment,interpersonal relationship and the organization from 140 senior students,through the online learning platform for encoding data to get the basic data,about 1 times,10 times,20 times peer evaluation quality of students Then through descriptive statistics,independent sample T test,one-way anova,non-parametric test and linear regression analysis and other data analysis methods,the following conclusions are drawn: In the early stage,students had low recognition of peer evaluation,but it was improved and remained stable in the middle stage.Students' attitudes vary according to their gender,online learning experience,mutual assessment experience and computer skills.Through participating in peer evaluation for many times,students can correctly understand and deal with the interpersonal relationship of peer evaluation process.Students' gender,communication style,evaluation experience and computer level will affect students' perception and handling of interpersonal relationship.In the early stage of peer evaluation,students could not adapt well to the organization of peer evaluation.The organizational style is influenced by students' gender,evaluation experience and computer level.The evaluation quality will improve with the students' repeated practice.In different periods,the quality of peer evaluation will vary according to students' gender,communication mode,evaluation experience and computer level.Students' attitude positively affects the evaluation quality,while interpersonal relationship and organizational style negatively affect the evaluation quality.
