数学是思维的体操.初中数学知识有机联系、纵横交错,解题思路灵活多变,解题方法途径繁多,即使一次性解题合理正确,也未必是最优的解法.这要求我们在课堂教学中既要注意一题多解、一题多变、一题多问,又要注意多题归一.既要及时引导点拨,鼓励学生进一步探索不同的解法,拓宽学生的解题思路,使学生在解题中运用知识、权衡解法优劣,更富有创造性地去学习、摸索、总结,使自己的解题能力更趋优化,又要解题后认真总结,摸索规律,举一反三.这样,对提高我们的解题能力大有帮助.现举例加以说明.
Mathematics is thinking gymnastics.Mathematical knowledge of junior high school organic relations, criss-cross, flexible problem-solving ideas, ways to solve problems, even if one-time solution is reasonable and correct, it may not be the optimal solution.This requires that we teach in the classroom We must pay attention to a solution to multiple problems, changeable questions, multiple questions to ask more questions, and pay attention to multiple questions to guide one. We must promptly guide them and encourage students to further explore different solutions so as to broaden students’ thinking in solving problems so that students To solve problems in the use of knowledge, weigh the pros and cons of solution, more creative to learn, explore, summarize, to make their ability to solve problems more optimized, but also to solve the problem seriously summed up, to explore the law, give top priority. Our ability to solve problems is very helpful.
