Luoyang math teacher invited 43 students with full marks in math to eat saute spicy chicken. I think this math teacher's practice can not only encourage students to study hard, but also inspire other students. Moreover, students will feel that it is an honor to be invited by the teacher to eat saute spicy chicken, and they will enjoy this honor very much, so they will be willing to work hard for this honor. I think this teacher's approach is desirable. This is a reward for students' good performance, so that students will be more motivated after being rewarded and continue to maintain this state in the next study. Moreover, the full marks of 43 students in mathematics show that this method of teachers can promote students' interest in learning. When the teacher offers such a reward, students think that the teacher's reward is very attractive and will study hard to get full marks. In this way, students' grades can be improved quickly, so that every student can reach a state of hard work. Many students are lazy in their studies, and they need the supervision of their teachers. Therefore, when the teacher sets them a goal and gives them a reward, they will be more motivated. If they want such a reward, they will try their best to achieve the teacher's goal. Therefore, teachers' practice can motivate students and make them willing to work hard in their studies. We can also encourage our students or children in this way in peacetime, so that they can be more motivated in their studies, because learning itself is a boring thing, which can give them some hope, feel that they have good grades and can get what they want, then they will be motivated and will make themselves work harder. They expect such a return. In this way, children's grades can be improved, and they can also be willing to take the initiative to learn, instead of being forced to study by teachers and parents every day. Therefore, we can learn from these methods appropriately to encourage children to study actively and study hard.
