Research On The Construction And Application Of Mathematical Resources For Deaf Students In Junior Middle Schools Based On Knowledge Map

The state has promulgated various educational policies to develop educational undertakings and advocate educational fairness.The development of special group education has attracted the attention of all sectors of society.The teaching force,school facilities construction,and learning resource construction of special education schools have been continuously optimized.Due to the large differences in cognition,knowledge learning and personality between deaf students and normal learners,the learning effect of deaf students is not ideal.Deaf students mainly obtain information through various learning resources,and the quality of learning resources has a greater impact on the learning effect of deaf students.At present,the quality of independent learning resources for deaf students is uneven,and they cannot help deaf students to construct a knowledge system structure.It is difficult for students to transfer and diverge knowledge.Therefore,the use of learning resources to help learners construct a knowledge structure system and promote knowledge transfer and divergence is a problem that needs to be solved urgently.This research takes the second-year deaf students as the research object,the junior middle school mathematics curriculum as the research content,and adopts the literature research method and the interview method.,Experimental research method,relying on the knowledge map to explore the methods and strategies of resource construction.Designed and produced knowledge map self-learning resources,and designed experiments to verify the effectiveness of the resources,providing help for mathematics teachers in frontline deaf schools and follow-up research.According to the results of data processing and discussion and analysis,the following conclusions are drawn:For the "number and algebra" category: knowledge learning part of the node knowledge representation method:(1)In the import link,the use of charts,line charts,matrix charts,and flowcharts will help enhance students' interest in learning and the creation of problem situations.For students' understanding of new knowledge;(2)In the explanation session,use concept maps,knowledge animations,flowcharts,and bridge diagrams to help learners remember and understand;(3)In the summary session,use mind maps to draw learners 'thinking Visualization helps the fusion of new and old knowledge and the mining of tacit knowledge,and helps learners to transfer knowledge;For the "space and geometry" category: knowledge learning part of the node knowledge representation method:(1)In the import link,use the combination of graphics and text to visualize the object,which will help enhance students' interest in learning and the creation of problem situations.Students' understanding of new knowledge;(2)In the explanation session,use bracket diagrams and knowledge animation to vividly show the composition of objects,which helps learners to remember and understand knowledge;use flowcharts to visualize the method of measuring cone height.Help students remember and understand;(3)In the summary link,use mind maps to summarize the knowledge learned and visualize thinking,which helps learners to integrate new and old knowledge,and helps learners to transfer and diverge of knowledge;For the "Statistics and Probability" category: Part of the knowledge learning node knowledge representation method:(1)In the import link,use the knowledge animation and complex flow chart to visualize the abstract "probability and statistics" knowledge,which will help improve students' learning The creation of interest and problem situations will help students understand new knowledge;(2)In the explanation link,use concept maps to construct the knowledge system structure,which will help learners remember and understand the knowledge of the average definition;use knowledge animation to Static knowledge becomes dynamic,attracting learners' attention,and helping learners understand knowledge;(3)In the summary link,using mind maps can integrate new and old knowledge and dig out learners' tacit knowledge,which is helpful Knowledge transfer for learners;knowledge representation method for some nodes of knowledge application: use interactive exercises to consolidate and strengthen the learning effect,and use flowcharts to visualize problem-solving thinking,which is helpful for learners to apply knowledge.
