在新课程复习中,要防止一个比较突出的问题,就是传统内容的超“标”超“纲”现象,例如,理科的立体几何,从新课标、新考纲及考试说明的要求看,复习求二面角时,对求作二面角平面角的几种几何方法要淡化.事实上,在必修2的立体几何初步中(或者说文科)没有涉及求角的问题,理科对求空间角的问题,要重点倾向于向量方法(坐标法).按照课标和考纲的要求,文科立体几何部分只学必修2的两章,而且其内容和要求较原大纲教材有大幅
In the review of the new curriculum, to prevent a more prominent problem is the super “superscript ” “class ” phenomenon of traditional content, for example, the three-dimensional geometry of science, from the new curriculum standard, Asking for a review, seeking for dihedrals requires diluting several geometrical methods of finding the dihedral plane angles.In fact, there is no question of angle-seeking in the initial three-dimensional geometry of Compulsory 2 (or liberal arts) In order to solve the problem of space angle, we should focus on the vector method (coordinate method) .According to the requirements of the curriculum standard and the syllabus, the three-dimensional geometric part of liberal arts only need to learn two chapters of compulsory 2, and its content and requirements are larger than the original syllabus
