The policy of "double reduction" aims at narrowing the educational gap and realizing educational equity, but the word "equity" should be treated correctly; "Fairness" is not "one size fits all". Every child's knowledge level and learning ability are different. For the same learning content, children with better level may feel "not enough to eat", while children with poor level can't keep up.
Therefore, the fundamental significance of educational equity lies in teaching students in accordance with their aptitude, so that different students can receive different education in different ways. How to truly teach students in accordance with their aptitude is a problem worthy of teachers' exploration, and it is also a problem that teachers must think deeply.
