Dynamic Tiered Design of Mathematics Assignments in the Context of"Double Reduction"
Dynamic tiered design of Mathematics assignments in the context of"double reduction"can not only teach students in accordance with their aptitude and reduce the burden of students,but also avoid the in-creasing polarization of students due to tiers.Therefore,it is necessary to build a database of mathematical tiered assignments,put forward the steps of construction of a database of mathematical tiered assignments and the common methods of dynamic tiered design and propose the prospects of research on tiered assignments.
