After the new curriculum reform, the traditional primary school mathematics classroom education has been completely denied. Doesn't it have advantages?

Comparatively speaking, primary school mathematics is the most practical course. Our traditional primary school mathematics classroom education is mainly based on teachers' "talking" and students' "practicing", which has been completely overthrown after the new curriculum reform. However, after the new curriculum reform, we found that teachers still choose traditional methods when attending classes or doing necessary exercises, because there are differences among students, and there are still quite a few children who can't adapt to the new curriculum reform and can't keep up with the learning rhythm. Explaining knowledge in traditional ways and then consolidating practice can make these children follow the rhythm without losing confidence in learning. Therefore, whether it is the traditional teaching method or the new curriculum reform, we must teach students in accordance with their aptitude, and we cannot kill them with one stick.
