认真研究了《中小学数学》(初中版)2010年第11期《学生容易理解的证明方法》一文后,为作者对下面这道题的研究精神,深表敬意!对于这道题,作者的两种解法,我相信会有一部分学生能看懂.不过我猜测,也许能理解、领会、掌握这道题的学生不会太多!不要说学生,就连许多教师对作者的这道题解法的理解,或多或少会觉得有一定的困难.因为,第一,两种解法的辅助线都多,解题时难以寻找;第二,技巧性高,解题时思维容易出现障碍,方法难以掌握;第三,解题过程过于繁琐,兴趣难以唤起;第四,思路不够清晰、流畅,过程不够简洁、精炼;…….为此笔者拟借贵刊这个重要
Seriously studied the “primary and secondary mathematics” (junior high school edition) in 2010 eleventh “proof of students' easy to understand,” a text, for the author of the spirit of the study on the following question, for this issue, the author Two solutions, I believe there will be some students can understand, but I guess, maybe to understand, understand, master the problem of students will not be too much! Do not say students, and even many teachers on the author of this problem solution Understanding, more or less will feel a certain difficulty .Because, first, the two solutions are more auxiliary lines, difficult to find problems; second, highly skilled, easy to trouble-shooting thinking problems, the method Difficult to grasp; Third, the problem-solving process is too complicated, difficult to evoke the interest; Fourth, the idea is not clear enough, fluid, the process is not concise, refined;
