近几年来,随着高中不断扩招,农村普通二类高中生源更差。因此,如何才能有效地组织课堂教学,如何很快地提高学生成绩,已成为每一位教师不得不思考的问题。鉴于此,根据近几年来在教学中的一些体验和实践,希望能对高中数学教师和学生有一些借鉴作用。 In recent years, with the continuous expansion of enrollment in senior high schools, the rural second-level senior high school students have even worse source of income. Therefore, how to effectively organize classroom teaching and how to improve student achievement rapidly has become a question that every teacher has to think. In view of this, according to some experiences and practices in teaching in recent years, it is hoped that there will be some reference to high school mathematics teachers and students.
