Research On Cognitive Diagnostic Of Dyslexia For 3-4 Grades

Object: from the perspective of pedagogy, psychometrics, etc, use rule space model and DINA model as diagnostic tool, in the consolidatio n of intergrating existing 3-4 grade reading disorder cognitive diagnostic t est, conduct fully cognitive diagnosis of reading disorder, and on this b asis to explore reading disorder and cognitive structure of typical model, provide intervention theories and practical instruction for reading disorder diagnosis; meanwhile, compare with DINA and rule space model from v arious aspects, promote the understanding of DINA and the model in the domestic application and development.Methods: study the literature of reading disorder both domestic and abroad, determine the theoretical framework of this research by conducti ng experts interview. Adopt stratified sampling method, select 6 primary s chools in Yiyang city, 2 urban-rural integration schools, 2 city schools an d 2 rural schools, with a sample volume of 1178 people, obtain 48 dyslexi a children test data by firmly according to the reading disorder children a dmittance standard.Results: 1. Master model: 13 kinds of RSM analysis and 12 kinds o f DINA analysis.mode 1111001100100 has a larger quantity of mastered people, for about seven to eight people, accounting for 15%- 17% in tota l; Followed by 1111001110100, 1111111100100, 1111111100110, 1111111110110, 1111111011100 and so on five kind of control mode, each have a bout 5 people, accounting for about 10% in total, the number of six kinds of patterns account for 65% people. 2 master probability.:3-4 grade dysl exia children to S1(rhyme), S2(notes), S3(syllable), S4(form nearly diff erent sound word pinyin), S7(named speed), S11(homonyms isomorpho us), and other attributes of the master degree is better; For S5(form nearl y different sound word meaning), S6(mirror), S8(memory span), the inte grated cognitive properties such as words(understand) the master degree in general, about 50% and 67% of dyslexia children have mastered these attributes, master of S10(sentence) and S12(morpheme) is lower, less th an 25%; he master degree of S13(morpheme) attributes is 0. 3. The comp arison of two models: compare DINA with rule space model in various w ays, proved that DINA model and the RSM has no difference on accuracy,but significantly lower than RSM model in learning and using difficulty, so using DINA model is feasible in academic research. 4. DINA calculati on program can significantly simplified DINA model of learning and usin g process, satisfy the demands of cognitive diagnosis research.Conclusion: 1. The analysis results of two models are basically the s ame, it can provide more diagnostic information. 2. The usage of DINA m odel on learning and application is simpler and easier.
