熟悉初中循环教学的同行应该知道,初中三个年级各个侧重点、难点不一样,七年级以“运算”(有理数、整式、解方程等)为主,学生需要过运算关,才有利于八、九年级的学习;八年级以平面几何(特别是全等三角形学习之后)的证明为主,较难的问题多数是几何证明题,如果学生没有能在八年级对常见、经典几何问题有很好的训练和适应,则相应的考试中往往会因为几何丢分很多;而九年级则面临着图形变换、函数综合问题,并且要应 Familiar with the teaching of junior high school cycle counterparts should know that the junior high school in all three levels of emphasis, the difficulties are not the same, the seventh grade to “arithmetic ” (rational numbers, integral, solution equations, etc.), students need computing off, Eight, nine grade learning; the eighth grade plane geometry (especially after the congruent triangle learning) to prove the main difficulties are mostly geometric proof questions, if students can not in the eighth grade on the common, classical geometry problems have Good training and adaptation, the corresponding test often because of the geometry of a lot of dropping; and the ninth grade is facing graphic transformation, the function of the integrated problem, and should be
