Study On The Characteristics And Intervention Of Interrogative Expression Ability In Hearing Impaired Children

Interrogative sentences are used in daily life to put forward questions and ask about the situation.Children can get all kinds of information by asking questions and getting answers.Adults can also improve children's language and cognitive development through question-and-answer interaction with children.Previous studies have shown that the interrogative expression ability of children with hearing impairment is significantly lower than that of children with hearing impairment,and there are few empirical studies on the interrogative expression characteristics and intervention strategies of children with hearing impairment in China.However,learning interrogative questions can gradually improve children's ability to understand speech,search and reorganize knowledge and experience,and express their own thoughts and feelings.Therefore,on the basis of previous studies,this study intends to explore the characteristics of interrogative expression in children with hearing impairment,and construct the intervention strategy of stepped interrogative expression in children with hearing impairment,so as to provide theoretical and practical basis for the intervention of interrogative expression ability in children with hearing impairment.The main results of this study are as follows:1.Research on the characteristics of interrogative expression ability of hearing impaired children.(1)Under the condition of matching PPVT-R score,the ability of interrogative response and initiation of hearing-impaired children is still significantly lower than that of hearing healthy children of the same age.(2)The interrogative response ability of both hearing impaired and hearing children is superior to the initiation ability.(3)It is easier for children to understand and express questions.(4)The number of question points is also an important factor affecting children's interrogative learning.(5)Children with hearing impairment showed irrelevant answer,imitation questions,grammatical errors,incomplete responses and other errors in the responses of questions.(6)In the initiation of questions,children with hearing impairment make improper choices of question words(sentences)instead of answers,as well as relevant descriptions and irrelevant descriptions.2.Research on the intervention strategy of interrogative expression ability of hearing impaired children.(1)According to the characteristics of children with hearing impairment's interrogative expression ability,a stepped interrogative intervention strategy is designed,which consists of experience,response,initiation and application.(2)The training effect of the stepped interrogative training strategy is remarkable.(3)The maintenance effect of the stepped interrogative training strategy is remarkable.(3)The stepped interrogative training strategy improves the ability of deaf children to generalize interrogative sentences in different language environments.3.Significance and innovation of this study:(1)By comparing the characteristics of interrogative expression ability of hearing-impaired children with that of hearing-impaired children,this paper analyzes the development rules of interrogative expression of hearing-impaired children and summarizes the typical types of interrogative expression errors of hearing impaired children.(2)In the system on the basis of analyzing the characteristic of the interrogative sentences express hearing impairment children,designed the initiated accord with the characteristics of children's experience,response,and using the four stages of spiral cascade questions intervention strategy,and validated through the experiment achieved the anticipated effect,promote the development of hearing impairment children question expression ability.
