Research On The Design And Practice Of "Network Sketchpad" In Junior Middle School Mathematics Teaching Under Intelligent Environment

The continuous advancement of educational informatization has brought opportunities for the continuous reform of the traditional teaching mode in the new teaching environment.The rational use of information technology and information teaching tools in mathematics classroom can effectively improve classroom efficiency,enrich students’ teaching resources and improve teaching methods.The application of Network Sketchpad in mathematics teaching in an intelligent environment can make the abstract and difficult to understand contents of mathematics more intuitive for students to understand and master,and further exercise and cultivate students’ high-level thinking abilities such as inquiry ability and cooperation ability.Based on the intelligent environment,this study uses the Network Sketchpad to assist the design of junior middle school mathematics knowledge points,and explores the application of the Network Sketchpad in junior middle school mathematics teaching under the intelligent environment.Firstly,this study uses the literature research method to sort out the relevant literature at home and abroad of intelligent environment,Network Sketchpad and related mathematics teaching auxiliary software,determine the research content,analyze and elaborate the relevant theoretical basis of the research,define the relevant concepts according to the research content,and analyze the characteristics and advantages of Network Sketchpad in mathematics teaching under the intelligent environment.Secondly,using the methods of questionnaire and interview,this paper analyzes the application status of teaching auxiliary software such as intelligent environment and Network Sketchpad among junior middle school mathematics teachers in Yinchuan,Ningxia,so as to provide a practical basis for the later design of this study.Through the investigation,it is found that there are some problems in junior middle school mathematics teaching,such as low utilization rate of intelligent environment,poor effect and low participation of students.The reason is that teachers lack the consciousness of deep integration of information technology and curriculum and the ability of teaching design in the process of teaching.Therefore,starting from the smart environment,it is necessary to use the information technology such as Network Sketchpad to integrate with junior middle school mathematics,design the teaching framework of Network Sketchpad in junior middle school mathematics under the smart environment,and explore the effect of the deep integration of Network Sketchpad and junior middle school mathematics under the smart environment.Thirdly,according to the current situation investigation,combined with relevant theoretical research,this paper designs the teaching design of Network Sketchpad in junior middle school mathematics classroom teaching under the intelligent environment.Based on dick Carrey’s systematic teaching design framework,starting from the goal,the teaching design analyzes the learning needs,learning contents and learners’ characteristics,combined with the advantages of Network Sketchpad in teaching under the intelligent environment,selects and develops appropriate teaching media resources,puts forward teaching strategies,constructs the teaching process of "three stages and ten rings",and determines the evaluation methods and dimensions.Finally,based on the "three stages and ten rings" teaching design process of the Network Sketchpad in the intelligent environment,using the experimental research method,a class in Grade 9 is taken as the experimental group to carry out mathematics teaching with the support of the Network Sketchpad in the intelligent environment;The other class served as the control group and was taught in a traditional classroom.Taking the chapter of "quadratic function" as the practical content,combined with teaching practice cases,this paper analyzes the teaching process of Network Sketchpad in junior middle school mathematics teaching under the intelligent environment;Analyze the results of the pre-test and post test of the experimental group and the experimental group and the control group,and verify the hypothesis that the Network Sketchpad can improve the mathematics performance and mathematics core literacy in the mathematics teaching of junior middle school in the intelligent environment;Using the survey method to conduct questionnaires and interviews with students and teachers respectively,analyze the results,and verify the experimental hypothesis of the impact of Web Sketchpad on students’ learning in junior middle school mathematics teaching in the intelligent environment.The results show that in the teaching of junior middle school mathematics in the intelligent environment,the Network Sketchpad can stimulate students’ interest in analytic geometry,improve students’ academic performance and efficiency,promote the cultivation of students’ core mathematical literacy and strengthen students’ independent exploration ability;At the same time,in the whole teaching process,it can improve the ability of junior middle school mathematics teachers to integrate information technology into subject teaching,strengthen teachers’ ability to use Network resources,and cultivate teachers’ level of developing teaching resources by using Network Sketchpad and other platforms.
