数学课程标准“强调从学生已有的生活经验出发,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”。在这新的教学理念指导下,怎样结合学生的实际生活,在运用知识解决问题的实践操作中,经历知识产生过程,萌发创造新知需要,并完成对新知的建构呢?下面结合“最大公约数”一课谈几点体会。
Mathematical Curriculum Standard “emphasizes starting from the student's existing life experiences, allowing students to experience the process of abstracting the practical problems into mathematical models and interpreting and applying them, so as to enable students to gain a better understanding of mathematics while at the same time having the ability to think, Values and other aspects of progress and development. ” Under the guidance of this new teaching philosophy, how to combine students' actual life, practice the process of applying knowledge to solve problems, go through the process of knowledge generation, germinate and create new knowledge, and complete the construction of new knowledge? The following combined with the "greatest common divisor A lesson a few experiences.
