“没有大胆的猜想,就没有伟大的发现。”猜想是指未经逐步分析,迅速对问题的答案作出合理猜测、设想或突然顿悟的思维。数学猜想就是指依据某些已知事实、已有经验和数学知识,对未知量及其关系所作出的一种似真判断,它是一种积极的创造性活动。随着新课程的实施,教师要善于启发、鼓励学生进行合理的数学猜想,引导学生获得知识、迁移知识、运用知识,以真正达到启迪思维、传授知识的目的。那么,在小学数学教学中何时引导学生进行数学猜想呢?其定位又如何呢?笔者仅以自己的教学实践为例谈几点粗浅的体会。
“Without bold conjecture, there is no great discovery. ” Conjecture refers to the idea of making a prompt guess, imagination, or sudden epiphany without prompt analysis of the answer to the question. Mathematical conjecture refers to a plausible judgment of unknowns and their relations based on some known facts, existing experiences and mathematical knowledge. It is a positive and creative activity. With the implementation of the new curriculum, teachers should be good at enlightenment, encourage students to make reasonable mathematical conjecture, guide students to acquire knowledge, transfer knowledge and use knowledge to achieve the purpose of truly enlightening thinking and imparting knowledge. So, when the primary mathematics teaching to guide students to guess the mathematical conception it? What is the positioning? I only use my own teaching practice as an example to talk about a few superficial experience.
