First, many students now have nine-year compulsory education, so at the educational level, it is said that every student can receive education. However, in some schools, because students are compulsory, many teachers are not responsible for teaching, but choose a very general brush, and even use QQ group or WeChat group to arrange homework. When correcting homework, they also help students to correct homework in a non-hands-on way, which reduces teachers' time and pressure to a certain extent, but at the same time, it also creates an irresponsible attitude towards students.
Second, the teacher corrects the homework personally and has a responsible attitude towards the students' learning, which can let the teacher know the students' learning progress and acceptance, and whether the students have mastered the topic and copied it, which will play a certain role in the students' learning effect. It is said that students are the flowers of the motherland, so a teacher should also perform the duties of a teacher and be responsible for students' learning. Since parents choose to entrust their children to school, they certainly hope that their children can succeed in school. In addition to their own efforts, of course, teachers need to be conscientious in teaching.
I think it is necessary for teachers to correct their homework in person, which is also a sign that teachers are responsible and perform their duties. It has played a certain role in the learning effect of students at school.
