新课程标准指出:数学课程的学习要引导学生“经历观察、实验、猜想、证明等数学活动,发展合情推理能力和初步的演绎推理能力。”“数学教学要让学生亲身经历将实际问题抽象成数学模型并进行解释与应用的过程,进而使学生获得对数学理解的同时,在思维能力、情感态度与价值观等多方面得到进步和发展。”由此可见,在课堂教学中,培养学生的推理能力十分重要。现实中,许多学生的分析推理能力较差,独立解决问题的能力也不足,对
The new curriculum standard states: The mathematics curriculum should guide the students to “experience mathematical activities such as observation, experiment, guess, proof and so on, and develop the ability of reasoning reasoning and preliminary deductive reasoning ability. ” “ Practical problems abstract into mathematical models and explain and apply the process, thereby enabling students to understand mathematics at the same time, in the thinking ability, emotional attitude and values, and many other aspects of progress and development. ”Thus, in the classroom teaching It is very important to cultivate students’ reasoning ability. In reality, many students have poor analytic reasoning ability and insufficient ability to solve problems independently.
