在中学数学基础知识和基本技能训练的教学中,适当进行“一题多变”“一题多问”的教学,对激发学生的学习兴趣,提高分析与综合、归纳和演绎的能力,使知识成串,加强基础知识和基本技能的训练是很有益的。下面结合二个具体例子,谈谈个人的粗浅看法: 一、一题多变所谓“一题多变”,这里仅指条件改变,能推出其他的结论。在习题课与复习课的教学中,就可以适当地选择有关“一题多变”的题目,来沟通新旧知识之间的内在联系,教给学生考虑问题的方法,提高学生分析与
In the teaching of basic mathematics and basic skills training in middle school mathematics, appropriate “multiple questions” and “one question and more questions” teaching will stimulate students’ interest in learning and improve the ability to analyze and synthesize, summarize, and deduce knowledge. It is useful to train and train basic knowledge and basic skills. Let’s talk about the individual’s superficial views in combination with two concrete examples: First, the subject is changeable The so-called “variety of topics”, here only refers to the change of conditions, can introduce other conclusions. In the exercises class and review class teaching, we can appropriately select the topic of “variable topics” to communicate the intrinsic relationship between old and new knowledge, teach students ways to consider problems, and improve student analysis.
