Research On Knowledge Construction Based On Peer-to-Peer Online Mutual Evaluation

The theory of knowledge construction believes that knowledge is no longer restricted to the construction of the individual itself,but is based on individual cognition and social consultation with the group.The knowledge construction model has been applied to teaching practice to a certain extent,and exploring multiple ways of knowledge construction is also particularly important for classroom teaching.As a new evaluation method,network peer peer evaluation has been used in classroom teaching.This thesis combines knowledge construction with peer evaluation on the Internet,and attempts to explore the way of peer evaluation through the network to explore the knowledge construction status of the students and whether the production level and various abilities have been improved,so as to make suggestions for student training..This article first clarifies the domestic and international research status of knowledge construction and peer evaluation on the Internet,and explores the general process of knowledge construction on the network;secondly,formulates an evaluation index system based on peer evaluation of public class works in "Modern Educational Technology" and uses an expert survey method to determine 6 first-level indicators,19 second-level indicators and evaluation criteria,including first-level indicators including teaching content,instructional design,technical literacy,media art,innovation and attitude,and the first-level indicators and second The weighting coefficient of the level index.While evaluating the peer works according to the evaluation index system,students also need to give comment feedback on the peer works.Then,we selected Hunan Normal University’s 2017 preschool education majors and geography education majors as the research objects,including 58 preschool education classes and 51 geography education classes,and carried out a 16-week network based on the "Modern Educational Technology" public class.In the study of peer evaluation,in order to ensure the effectiveness and fairness of peer evaluation,the activities of mutual evaluation are arranged in class,and the creation and modification of works are arranged after class.Each student submits a total of 2 works,and each work undergoes three rounds of mutual evaluation.Among them,from 1 to 7 weeks,a professor of technology related to theoretical knowledge and production production is arranged,and the task requirements for the creation of the work are arranged,and the students start to select topics;in the fifth week,the students’ mutual evaluation of the creative plan is carried out;in the 10th to 15th weeks,the teachers are in After teaching,leave enough time to carry out peer evaluation activities;in Week 16,in order to explore the knowledge construction level reached by students after peer evaluation on the Internet,a theme discussion activity was conducted.Pre-school education and geography education classes are held once a week.Students submit their works to the learning platform within the prescribed time and evaluate them according to the evaluation index system.Finally,the content analysis method and questionnaire survey were used to organize and analyze the collected student evaluation data and questionnaires,and the following conclusions were drawn:First,students maintained a proactive attitude in the process of creation and mutual evaluation of works,and network peers evaluated each other Opened a new way for students to learn;second,online peer peer evaluation can improve the level of student’s work creation,students’ works are continuously modified and improved along with the cycle of online peer peer evaluation,and the student’s creative level has been improved;third,With the peer review of works,the students’ creative ability,reflective ability,and criticism ability have been improved.Fourth,in peer peer assessment,students are the main body,but teachers must continue to guide students to evaluate the fairness and justice.Fifth,negotiate and construct in the constant communication and interaction of peer evaluation,and the student’s knowledge system is updated and perfected.
