Jacques-dodson Law is a motivation theory put forward by two psychologists, Jacques and dodson. The main contents are as follows: the relationship between motivation level and learning effect is inverted "U", and the middle level of motivation arousal is most conducive to the improvement of learning effect. In order to achieve the best learning effect, the best motivation level is closely related to the difficulty of homework. The easier the task, the higher the best motivation level. When the difficulty of the task is medium, the best motivation level is also medium; The more difficult the task, the lower the optimal incentive level.

Its educational significance: In the teaching process, teachers should appropriately control students' motivation level according to the different difficulties of learning tasks. When the learning task is relaxed, we should try our best to create a learning atmosphere that allows students to concentrate and make students nervous as much as possible; When studying more complicated and difficult subjects, we should try our best to create a relaxed and free classroom atmosphere. When students encounter difficulties or problems, they should try to guide them calmly and slowly to avoid excessive tension and anxiety.
