在新课程教学中,“猜想”作为探究性学习方式被引入数学教学中,它是教师指导学生依据已有的数学材料或知识经验,做出符合一定规律或事实的推测性猜想,然后进行验证,并在解决问题的过程中发现新问题,从而完善原有猜想,最终发现规律。实际上,它是一种数学想象,让学生在经历猜想的过程中开阔视野、活跃思维、提高探究能力。借助“认识体积和容积”一课谈几点看法。 In the new course teaching, “guess ” is introduced into mathematics teaching as inquiry learning method. It is a teacher who guides students to make speculative conjectures conforming to certain rules or facts according to the existing mathematical materials or knowledge experience, and then Verify, and find new problems in the process of solving the problem, so as to perfect the original conjecture and finally discover the law. In fact, it is a kind of mathematical imagination, which enables students to broaden their horizons, to be active in thinking and to improve their inquiry ability while they are undergoing conjecture. With “understanding volume and volume ” a few talk about a lesson.
