许多数学习题,它不是把所有的条件都直接明了地告诉学生,而是把某些条件隐含在习题的其它条件、结论或数学式子当中,学生在解题过程中,往往容易忽视这些隐含条件,而导致解题错误,造成学生错误的原因主要有以下三方面,一是分析条件不够仔细缜密,二是解题过程不够规范完备,三是解 Many mathematics problems do not directly tell students all the conditions, but rather imply some conditions in other conditions, conclusions, or mathematical formulas of the problems. Students often overlook these hidden conditions in solving problems. Containing conditions, which led to problem-solving errors, caused student error mainly due to the following three aspects. First, the analysis of conditions is not careful enough. Second, the problem-solving process is not standardized and complete. The third is the solution.
