新课程标准明确指出,在教学时要充分利用教材的空间,注意满足不同学生的需要,可以根据地区和学生的实际情况,合理地组织和使用教材。数学是一门科学性、系统性非常强的学科,其内在的知识结构及严密体系,决定了数学教学必须实施分层次教学的原则。在全面实施九年义务教育的今天,学生从小学进入初中,可以说不同的学生从知识水平、心理特征、能力发展和学习态度等都存在着许多个性差异,因此我们应实施分层次教学。
The new curriculum standards clearly point out that in teaching, we must make full use of the space of teaching materials and pay attention to meeting the needs of different students. We can organize and use teaching materials in a rational manner according to the actual situation of the region and students. Mathematics is a scientific and systematic discipline, and its internal knowledge structure and strict system determine the principles that must be implemented in mathematics teaching. In the full implementation of nine-year compulsory education today, students from primary school to junior high school can be said to have different personality differences from different levels of knowledge, psychological characteristics, ability development and learning attitudes. Therefore, we should implement teaching at different levels.
