Expansion: First of all, whether it is legal for primary schools to attend classes on Saturday needs to be judged according to the policies and regulations of local education administrative departments. China's Ministry of Education has promulgated the Compulsory Education Law and the Regulations on the Management of Primary and Secondary School Teachers, which clearly stipulate that schools in the compulsory education stage should set courses, assign homework and evaluate exams in accordance with regulations to ensure that students have enough time to study, rest and exercise. In addition, local education administrative departments will also issue specific policy documents, stipulating that primary schools will start classes on Saturdays.
Secondly, primary school classes on Saturday need to be evaluated according to the specific situation. The concept of "primary school" includes all age levels from 1 to grade 6, and its learning tasks and goals are different. Therefore, in the concrete implementation of Saturday class, we need to consider the factors such as students' age, subject characteristics and learning progress, avoid formalism and ensure students' physical and mental health.
In addition, the opinions of parents and students need to be considered in primary school classes on Saturday. Schools should fully respect the opinions of parents and students, listen to their voices and understand their needs and concerns. At the same time, schools should also actively convey education policies to parents and students, introduce teaching arrangements and objectives, ensure information symmetry, and reduce unnecessary misunderstandings and disputes.
To sum up, the legality of Saturday classes in primary schools needs to be evaluated in light of specific conditions. Schools should abide by the relevant laws, regulations and policies of the state, fully consider students' physical and mental health and actual learning needs on the basis of fully respecting the opinions of parents and students, reasonably set courses, arrange homework and exams, and ensure the improvement of students' learning effect and quality. Only in this way can we truly achieve the goal of primary education and cultivate healthy and growing future talents.
