An Empirical Study On The Visualization Of Knowledge Visual Ability Of Training Of Junior Middle School Students

With the development of information technology and social progress,deaf students' education is getting more and more attention.However,due to deaf students' own hearing defects,leading to ordinary teaching methods in them who do not achieve better teaching results,therefore,to meet the cognitive characteristics of hearing impairment students to learn the ability to express the general method is very necessary.The Knowledge visualization has been widely concerned by educational researchers,and visualization can visualize,materialize and visualize complex knowledge content.For students with hearing disabilities,this is a way to make up for their own lack of teaching methods.First of all,according to the literature research method to find the advantages of knowledge visualization tools,according to the interview method to understand the learning characteristics of hearing impaired students,knowledge visualization theory as the theoretical basis of hearing impairment student resources to complete the design of visual teaching resources.According to the experimental research method,the validity of knowledge visualization is applied to the cultivation of written language expressive ability of hearing impaired students.The results showed that:(1)In the previous two experiments,there were significant differences in the test scores between the experimental group and the control group,and there were significant differences between the experimental group and the posterior test scores.(2)In the third experiment: Although the experimental group and the control group in the test results there are still significant differences,but the experimental group of pre-test and post-test scores are not significant.Study on the Effect of Language Expression Ability of Hearing Impaired Students in Online Environment.The results show that:(1)the written grammar structure of hearing impaired students can be correctly regulated.(2)Hearing impaired students can communicate their views through the various expressions such as words,animation,pictures and video in the network environment,and express their views in a variety of ways.(3)Hearing students learn through online discussion,Can promote the acquisition and construction of knowledge.Finally,the results of empirical research are analyzed,and the training strategies of improving the written language expressive ability are accorded with the cognitive characteristics of hearing impaired students.
