Parents and teachers expect too much from their children, but lack scientific educational methods. In desperation, they take coercive measures to achieve short-term expected results.
For example, due to the differences in children's intelligence types and development, there are high and low academic performance. The correct educational method should first analyze the reasons for individual's high or low performance, and then put forward targeted learning plans to make up for each other's shortcomings and make students accept this learning method and this result. However, the education of "pulling out seedlings to encourage others" can't teach the law at all, and it doesn't accept such a result at all, forcing unacceptable educational means on students. Although it may achieve certain results in the short term, it will have adverse effects on students in the long run.
