First of all, from a legal point of view,
Legally speaking, schools have the right to formulate and implement students' learning and behavior norms and stipulate students' disciplinary and punishment policies. Decreasing marks is one of the punishment methods, which aims to punish students' improper behavior and make them realize their mistakes and consequences and correct them. According to the relevant laws and regulations, schools can deduct points before learning, or deduct points after learning, as the case may be.
Second, from the perspective of education.
From the perspective of education, the school emphasizes both education and punishment, that is, it pays attention to education while punishing students. Therefore, the treatment of learning first and then deducting points is more in line with the essence of education. After students violate the school rules, the school can educate them first, so that they can realize their mistakes, understand the rules and requirements of the school, strengthen their sense of self-discipline and discipline, and then deduct points.
Third, from a practical point of view.
From a practical point of view, learning after deducting points and learning after deducting points have their own usage scenarios and advantages and disadvantages. The method of deducting points first and then learning will make students more alert and reduce the occurrence of violations. However, this method may make students feel disgusted with the deduction and unwilling to receive education. The method of learning first and then deducting points can make students get better education, and strengthen their sense of discipline and self-discipline while punishing them. However, this method may make students focus on deducting points and ignore the content of education.
Generally speaking, the penalty for learning the law should pay equal attention to education and punishment, and the treatment of penalty after learning is more in line with the essence of education. In practice, it can be used flexibly according to the specific situation, so that students can get better punishment and education. At the same time, students themselves should consciously abide by the school discipline, develop good behavior habits, and avoid being penalized for violating the rules.
