To increase motivation, there is one very interesting option - the use of childish, comic "contracts" (original contracts), concluded between the teacher and students. In such an agreement (after a joint discussion), the amount of work, its quality and evaluation is clearly recorded. Such contracts - not only develop and organize students' independence, but also create a psychological atmosphere of safety, responsibility and freedom in the process of training.
Motivated to achieve success, students actively seek funds, while experiencing positive emotions, mobilizing internal resources.
P.S.
Analysis of the literature has shown that the concept of cognitive motivation is internally connected with other, related concepts, among which one can distinguish:
Cognitive interest (emotional inclusion in the solution of the task)
Creativity (creativity) - to put something into your idea
Curiosity (the desire to learn something new)
All these concepts are close in content, they have a common unifying principle - a person's orientation to the unselfish recognition of the new and getting a sense of satisfaction from the very process of mental effort, that is - motivation.
