The Research On The Effectiveness Of Mathematical Knowledge Representation Of Primary School Deaf Students From The Perspective Of Knowledge Visualization

Education starting point,fair resources allocation are promoted by the development of special education,which is one of important ways to move towards education information.The education ministry in China has always focused on the construction of information resources during the progress of education information.However,the learning resource of deaf students is different due to the fact that there are differences between deaf students and normal students.Th erefore,how to present cognitive advantages in visual aspect of deaf students and use visual lan guage to present knowledge required in a visual way to present tacit knowledge of teachers and students is the problem to be urgently settled at the present time.Appropriate ways of knowledg e representation need to find in order to solve these problems,which are better presented to stud ents.From the perspective of knowledge visualization,this research,taking primary school deaf students in grade five as research object,analyzes mathematical knowledge,explores representat ion mode which corresponds to knowledge point and verifies the effectiveness of presentation st yle on the basis of other studies to provide reference experience for the frontline's educational w orker and resource builder.Firstly,literature about knowledge visualization and learning resource are found,cognitive characteristic of deaf students are analyzed in primary school,the current situation of knowledge representation is understood through literature review.This research reviews overseas and domestic research status of knowledge visualization and learning resource;Communicating and discussing with special schools' teachers in Chengdu and Neijiang by interview to find out some difficulties and problems in primary school mathematics knowledgeSecondly,design principles of mathematics knowledge representation in primary school have been presented according to the constructivism theory,information processing theory and cognitive load theory.Next,simple and vivid,simple and abstract,complex and vivid visual learning resources are designed and developed according to mathematics knowledge representation principles in primary school.Visual learning resources of mathematics knowledge representation for deaf students in primary school are achieved by Seewo whiteboard 5Thirdly,effectiveness of mathematical knowledge presentation styles of deaf students in primary school has been explored through experiments.Effectiveness experimental study of ready-made visual learning resources has been conducted combined experimental scheme and effectiveness of presentation style has been verifiedFinally,the data of simple and visual knowledge date,simple and abstract knowledge and complicated and visual knowledge is collected by Excel.Experimental data is analyzed and the corresponding conclusion is come to the by SPSS22.0.When data analysis is done,it is subset analyzed experimental group and control group,gender of experimental group and experimental area three dimensions,which are respectively divided into three parts.Research shows that:(1)It is good for simple and visual knowledge that establishing a scenario by knowledge animation,organizing and judging methods by flow chart,representing ways to solve problems by knowledge animation and flow chart,presenting conceptual knowledge by knowledge animation.(2)Concept map represents knowledge,flow diagram and represents ways to solve problems are good for simple and abstract knowledge(3)Bubble map represents concept and knowledge animations represents are good for complicated and visual knowledge.
