It is necessary to make full use of summer vacation time to help children find out and fill in the gaps in primary school knowledge. If possible, children can participate in relevant primary and secondary school convergence remedial classes to make a good connection between knowledge and learning methods. After children enter junior high school, they should strengthen communication with class teachers and classroom teachers, keep abreast of children's learning situation, find problems, help children analyze the reasons in time, and discuss solutions with teachers so that children can catch up in time and not fall behind.
