数学教学不仅要考虑学科本身的特点,更要从学生已有的生活经验出发,让学生经历将实际问题抽象成数学模型,并用数学模型进行解释与应用的过程,旨在使学生获得对数学形成过程的了解与内化。在这一理念的指导下,许多教师都在挖掘数学与生活的联系,努力在生活中寻求各种原型。然而,许多教师由于经验的缺乏和认识的不清晰,在实践中存在着一些偏差。 Mathematical teaching should not only consider the characteristics of the subject itself, but also start from the student’s existing life experiences, let the students experience the abstraction of practical problems into mathematical models, and use mathematical models to explain and apply the process designed to enable students to obtain a mathematical formation Process understanding and internalization. Under the guidance of this concept, many teachers are digging the connection between mathematics and life, and strive to seek various prototypes in life. However, due to lack of experience and lack of understanding, many teachers in practice have some deviations.
