我国的普通中学分为初中和高中两个阶段,均属基础教育。前者为义务教育阶段,后者为基础教育的高层次。初中,根据义务教育的性质任务,精选了社会对数学的一般需要和学生就业实际需要的最基本、最有用的代数、几何和统计初步等知识,以及与学习其他学科相配合的知识,适当拓宽了知识面,降低或减弱了某些知识的理论要求,使课程教材内容有利于提高全体学生的数学素养,切合义务教育的宗旨。 China’s ordinary middle schools are divided into two stages, junior high school and high school, and all belong to basic education. The former is the compulsory education stage and the latter is the high level of basic education. In accordance with the nature and tasks of compulsory education, junior high school selects the general needs of the society for mathematics and the basic, most useful algebra, geometry and statistical preliminary knowledge required for the actual employment of students, as well as the knowledge that is appropriate for learning other disciplines. Broadening knowledge, reducing or weakening some of the theoretical requirements of knowledge, so that the content of course materials will help improve the quality of all students’ mathematics, to meet the purpose of compulsory education.
