And reducing the burden and increasing the efficiency has become the primary goal of modern education. This paper mainly studies the strategies of primary school mathematics homework design under the background of double reduction, and finds the most scientific and effective way. And in the future primary school mathematics teaching work, we should not only do to reduce students' homework burden, but also to ensure that students can achieve efficient learning.展开更多

First of all, it analyzes the necessity of carrying out large-scale unit subject teaching and determines the actual procedure of carrying out large-scale unit subject teaching. Homework is an effective tool to increase students knowledge, and its effective design is more important to improve students learning ability. When designing the biology homework of basic schools, we should pay attention to the homework based on basic knowledge, the design of the hierarchical homework, and also pay attention to the openness, practicability and integration of the process.展开更多

On the basis of analyzing reverse selection questions,this paper provides a design capability screening model,which can make a designer automatically expose his hidden information so that necessary actions can be taken as required by the owner to realize risk sharing. A calculation example is finally given to demonstrate that the new model is helpful for an owner to select a designer with high professional level and to lead the designer to work hard,so it is of significant application value.展开更多
