Application Research Of Collaborative Knowledge Construction Based On Mind Map

Social construction theory believes that the acquisition of knowledge is not a process of simply accepting and copying knowledge,but in a certain social and cultural environment,learners construct knowledge through interaction,communication and cooperation.Collaborative knowledge construction can not only promote students to carry out various high-level cognitive activities,but also enhance students’ coordination and problem-solving abilities.Deep learning plays a pivotal role in school education.According to 2014 data from the American Research Association,deep learning is the key to the success of school education,and teaching focused on deep learning can significantly improve students’ learning outcomes.Although many scholars have made in-depth discussions on collaborative knowledge construction from different perspectives,there are still problems such as insufficient knowledge preparation,insufficient skills,and insufficient discussion in the construction of collaborative knowledge.Buzzard T came up with mind maps in the early 1960 s,what he believed to be the prevailing note-taking.There are no keywords,it is not suitable for memory,it is a waste of time,and it is not effective in stimulating the brain.Mind maps can integrate sporadic knowledge,enable students to learn meaningfully,stimulate students’ interest in learning,make students actively participate in learning,and strengthen unity,cooperation and equal communication between teachers and students.Mind maps can arouse students’ attention to knowledge,preview knowledge points,sort out opinions,and communicate,so that students can realize in-depth learning in the construction of collaborative knowledge.Therefore,this paper combines mind mapping and collaborative knowledge construction to solve the problems of students’ weak learning motivation and insufficient deep learning ability.Firstly,according to the collaborative knowledge construction five-stage model and eleven-stage model,according to a certain theoretical basis,the collaborative knowledge construction model based on mind map is designed.The newly formed building model is then put into practice.Through questionnaires,SOLO classification evaluation theory and other methods to analyze and evaluate the results of students’ collaborative knowledge construction,from the perspective of Ausubel’s cognitive assimilation theory,it sorts out the problems in collaborative knowledge construction and proposes effective solutions.After three rounds of action research,the following conclusions were obtained（1）Collaborative knowledge construction based on mind maps is divided into individual knowledge construction（acquiring information,integrating information,and constructing mind maps individually）,collaborative knowledge construction（open sharing based on mind maps,There are three major parts and ten small parts:argumentation and explanation,meaning negotiation,creation of mind maps and public expression,reflection）,teacher guidance（seeking teacher guidance,listening to teachers’ optimization plans）.（2）Pay attention to the following problems in collaborative knowledge construction based on mind maps.First,clarify the key and difficult points of teaching,and reasonably arrange the pre-knowledge points;Second,teachers guide the whole process of knowledge construction;third,sort out problems and demonstrate and explain;Fourth,effective discussion and negotiation of meaning;Fifth,offline reflection is the main,and online reflection is supplemented.
