数学新课标指出:“人人学有价值的数学,人人都能获得必须的数学,不同的人在数学上得到不同的发展。”然而,传统的课堂教学均采用统一的尺度组织教学,课堂教学形成“一刀切”。违背了因材施教的原则,没有达到全体发展的目的。怎样打破这个局面呢?通过多年的教学实践,针对学生的差异,对班里学生依据基础和成绩,把学业水平相当的学生分在同一层次里。同时,分层时注意学生的兴趣爱好,学科的互补性,力求在同一层次里的学生能够相互激励,相互促进,取长补短,发挥各自的优势,共同提高成绩, The new curriculum of mathematics points out: “Everyone learns valuable mathematics, and everyone can acquire the necessary mathematics. Different people get different developments in mathematics.” However, traditional classroom teaching adopts a uniform scale organization. Teaching, classroom teaching is formed “ across the board ”. Violating the principle of teaching students in accordance with their aptitudes did not achieve the goal of overall development. How to break this situation? Through many years of teaching practice, according to the differences of students, students in the class are grouped on the same level according to the basics and achievements. At the same time, when stratification pays attention to students’ hobbies and interests, and the complementarity of disciplines, students at the same level should be encouraged to encourage each other, promote each other, draw on each other’s strengths, and develop their own advantages.
