For the compilation of the subject unit content, the contents of each unit are divided into different class contents according to different knowledge content and knowledge structure, and this knowledge dissemination method based on unit arrangement is the main means of English teaching. Therefore, many teachers have established the model of unit teaching as much as possible from the perspective of big concept on the basis of existing knowledge structure. Through the exploration and analysis of this systematic teaching mode, the extension means of teaching are put forward, and then the corresponding reference for the teaching mode of English classroom is provided. This paper, based on the actual requirements of the overall teaching structure of the unit, analyzes the necessity of the overall teaching configuration of the primary school English classroom unit from the perspective of big concept, and puts forward the corresponding problems and rectification measures, so as to improve the quality of the primary school English classroom teaching and lay a solid foundation for the reform of the primary school English teaching.展开更多

A new theory and method for MC-oriented evolutionary design of configuration product is presented based on the study of developing law of evolutionary design in integrated envi-ronment, which focuses on the innovation and reuse properties of configuration product. The key technologies for general requirement modeling in quick response to customer requirement, multi-level stepwise configuration optimization driven by customer requirement and evolutionary deduction of product variable structure based on configuration association are thoroughly investigated. The suc-cessful application of the presented method in the development of real-life products demonstrates its utility, flexibility and robusticity.展开更多
