数学是科学的发展从定性的认识走向定量化认识的必要手段,是科学认识不断发展和完善的重要而必备的工具。学习物理离不开数学,在物理教学中,有些物理概念、规律需要用数学语言、数学公式表达。但数学知识和物理知识都有各自的特点,在许多情况下,脱离实际,用“纯数学”观点去认识物理概念、规律,解决物理问题,则必然导致物理问题数学化的错误,违背物理规律。这一类错误在初中学生中可谓是屡见不鲜,它
Mathematics is a necessary means for the development of science from a qualitative understanding to a quantitative understanding, and an important and necessary tool for scientific understanding and continuous development and improvement. Learning physics can not be separated from mathematics. In physics teaching, some physical concepts and laws need to be expressed in mathematical language and mathematical formula. However, both mathematical knowledge and physical knowledge have their own characteristics. In many cases, out of touch with reality, using “pure mathematics” point of view to understand physical concepts and laws and solve physical problems inevitably leads to mathematical errors in physical problems, Physical laws. This kind of mistakes can be described as common in junior high school students, it
