Research on the construction of a motor quotient(MQ)assessment model for preschool children is still in its primary stage and remains to be desired.In this context,the development of the research holds considerable theoretic values,contemporary relevance and practical significance for enriching relevant theories,expanding research on pre-school education into new sectors and bolstering up research on educational assessment in China.The research,which has drawn on the paradigm of a series of assessment models for basic education,is based on adaptive behavior theory and the operational definition of preschool children's MQ.It formulates the index system of the MQ evaluation for pre-school children aged 3-4 years by a combination of qualitative analysis and quantitative analysis.Based on analytic hi-erarchy process(APH),entropy method and least-square method,this paper obtains the weight of each index and estab-lishes the preschool children's MQ measurement model.In the end,this paper verifies the validity,reliability and opera-bility of the model in terms of approval from experts and practical application.
