Primary School Information Technology Teaching In The Application Of Knowledge Visualization Research

With the rapid development of education modernization and education informationization,asked to improve students' comprehensive qualities in education goal,raises has "divergent and creative thinking" and "collaborative communication" and "read figure and graph" ability of new talent information society;At the same time,the status of information technology disciplines is becoming more and more attention,the same old,teaching methods and teaching means has gone far can not meet the requirements of the new era of education.In this context,the teaching of knowledge visualization can be developed.Knowledge visualization teaching mainly use their visual representation tool to complex abstract knowledge content into clear image is easy to be accepted by the cognitive image,to reduce the cognitive load,accelerate the understanding of the knowledge,transfer,help learners study easily.Mind mapping as a typical representative of knowledge visualization visual representation tool,one has been widely applied in the education teaching by international scholars in the field of,its advantages in conformity with the elementary student's cognitive characteristics,and the education of primary school information technology curriculum goal,discipline characteristic with phase eligibility.This study attempts to use mind mapping as the main visual representation tool to explore the application of knowledge visualization in primary school information technology teaching.The research methods used in this study include literature research,questionnaire survey,interview survey and experimental research.This article combing knowledge visualization definition,research background,present situation at home and abroad and analyzes the characteristics and primary school pupils' cognitive characteristics of information technology disciplines,expounds the theoretical foundation of knowledge visualization teaching,to build a primary school information technology based on mind mapping knowledge visualization teaching mode,the using principles and teaching evaluation are discussed;At the same time,combined with the five grade PowerPoint curriculum,the teaching model is verified by practice to prove its feasibility in teaching practice and the promotion of classroom teaching;Through the practice of teaching,knowledge visualization teaching can improve students' interest in class and visual literacy,optimize students' composition ability in computer work,and also promote the academic performance.
