Design And Practice Of Junior Middle School Information Technology Teaching Activities Based On Visual Tools

In recent years,with the rapid development of global education informatization,the importance of the status of information technology disciplines has become increasingly apparent.At the same time that the new curriculum reform poses new challenges to traditional teaching methods,the real problems in information technology teaching in junior high schools have also emerged.Abstract knowledge is difficult for students to understand,and students' ability to operate is not strong.At present,many experts and scholars continue to study new teaching models through various new technical means,and put forward "visual learning".Since the advent of visualization tools,people have been receiving continuous attention and applied in various fields.They believe that in visual teaching An important research content is the visual transmission and collision of knowledge and thinking.The teaching space supported by information technology can often give full support to visual teaching and maximize its advantages.This research considers the use of visualization tools to solve the problem of teaching pains in information technology disciplines,proposes the comprehensive application of visualization tools in junior high school information technology teaching,and attempts to design teaching activities and practice effects to try to meet the needs of the current teaching organization.To achieve the information literacy of junior high school students on the requirements of the new curriculum reform,improve the level of information skills,and solve real problems.This article is mainly based on the analysis of visual teaching related research at home and abroad,guided by schema theory,learning support theory and activity theory,combined with the current situation of information technology teaching in junior high school,the three major types of visualization tools proposed in this article are applied to teaching.Analyze the advantages,and construct teaching activity designs based on visual tools based on relevant concepts and theories.Through the creation of five contexts: problem situation,thinking analysis,group collaborative interactive learning,teacher guidance,and self-evaluation,the content of knowledge and each Select the appropriate visualization resources and tools for the teaching effect to be achieved in the link,and then carry out research on the teaching actions of the visual tools in the internship school where the author is located.After each round of action research,continuously improve and perfect the design of teaching activities,and design based on the teaching activities.Finally,through the questionnaire survey and classroom observation methods to analyze the teaching effect,to understand the students' grasp of knowledge and information skills,combined with teacher and student feedback to summarize the problems in teaching practice,and put forward the application of visual tools to improve the effectiveness of information technology Strategy.The results of practical research show that the visual tools designed in this paper have more advantages in the practice of junior high school information technology teaching than traditional teaching models,and the research is applicable and effective in junior high school information technology teaching,which can help improve curriculum teaching Quality,inspires students 'interest in learning,improves teaching effectiveness,and helps to cultivate students' information literacy.In the next step,we will continue to strengthen the research of data visualization applied to teaching,and continue to expand the scope of application of course types,make practice more perfect,and continuously improve students' practical ability.And conduct teaching practice research.
