teach students in accordance with their aptitude

Whether it is "encouraging seedlings to help others" or "practicing without paying attention to festivals", it means teaching students in accordance with their aptitude. That is, teaching can't go beyond the actual situation of students, and can't teach too much and too deep knowledge to small and dull students, which is beyond their acceptance ability and makes students "unable to eat"; Don't teach too little to big and talented students, so that they don't have enough to eat. Because it violates the principle of gradual progress.

Teaching principle

At present, some schools engage in surprise attacks, competitions, sea tactics and one-sided pursuit of enrollment rate, which are contrary to the principle of gradual progress and will not have any effect. Even if it works occasionally, it will never last. One example is that many students can't keep up with their homework after entering the university by surprise. As everyone knows, "more is confused" and "haste makes waste".

Law of individual physical and mental development

Pulling out seedlings encourages others to do things rashly, which violates the sequential law of individual physical and mental development.
