What are the incentive mechanisms for children to take online classes?

The specific rewards are: 1. Reward vouchers for students who perform well, such as handing in homework on time, and get praise from other teachers. Students can receive "prizes" by accumulating a certain number of incentive vouchers, such as having lunch with teachers, drawing prizes from prize boxes, being allowed to drink soft drinks and eat popcorn on Fridays.

2. Cut the poster into small pieces of paper, write down interesting topics on the pieces of paper, wrap it in a big letter, and hang the envelope next to a small blackboard. If all the students in the class are doing well, or praised by other teachers, or doing well in class, take out a piece of paper from the envelope and stick it on the blackboard. If the students answer the questions on the test paper correctly, they will give the whole class a special reward.
