Research on the Impact of Expectation on Knowledge Sharing of Online Learners

From the perspective of network evolution game, this paper analyzes the impact of expectation on online learners' knowledge sharing behavior, so as to promote learners' knowledge sharing. On the basis of expectation confirmation theory and network evolution game theory, this paper constructs an online learner knowledge sharing model. Through experimental simulation, the evolution process of online learning platform knowledge sharing under different expectations is compared, and the mechanism of expectation on learners' knowledge sharing behavior is analyzed. The research results show that expectations have a significant impact on the knowledge sharing behavior of online learners, and appropriate expectations can improve the level of knowledge sharing. Therefore, this paper puts forward the management enlightenment of knowledge sharing of online learning platform, which has practical significance for the future development and construction of online learning platform.
