Exercises include two kinds of exercises: exercises to deepen students' understanding and memory after learning the text, and practical skills that workers, soldiers and others often perform certain actions in order to acquire skilled skills, such as classroom exercises, after-school exercises, lathe driving, welding, cooking, broadsword, shooting and formation.

Psychological explanation

Practice refers to the process of improving specific skills by repeating one or an operation. Exercise is often used to learn some sports skills or mental skills, the former is to learn swimming, and the latter is to learn mathematics to solve problems. The effect of practice can be measured by the improvement of correct rate or the decrease of error rate.

Psychological research on practice shows that the so-called "plateau phenomenon" often appears in the process of improving skills through practice, that is, when performance reaches a certain level, performance will linger for a long time, and the reason is often related to the operation mode that is not conducive to more efficient operation.

Skilled or automated skills can be achieved through sufficient practice, that is, operators can pay less attention to and engage in operations with less redundant actions.

In addition, practice needs to enhance the motivation of practitioners, prevent the motivation from being reduced due to monotony, and prevent the practice from being overloaded. In addition, the practice of mental skills should avoid too simple operations, and pay attention to introducing variants, so that practitioners can form correct concepts and representations.

The practice of one skill operation is conducive to mastering another skill operation, which is called practice transfer, also known as learning transfer.

Practice notes

When practicing, the trainer should choose the exercise items according to his age and physical condition. Old people are suitable for walking and jogging, while young people are suitable for some large-scale training programs, such as basketball, football and long-distance running. Teenagers should not do too much exercise, otherwise it will be harmful to their physical development.
