众所周知,数学模型是针对参照物的特征和数量关系来形式化的语言概括.但一谈到建立数学模型很多教师都很不自信,总觉得这只是出自专家们口中的语句,距离实际教学很遥远.其实,数学本身就是一种模型式的教学.一、创建问题情境,让学生感受数学的形成目前,新课改虽然已经普及,但是在教学实践中,仍然能够看见“知识技能”与“过程方法”脱轨的痕迹,教 It is well-known that mathematical models are formalized language generalizations based on the characteristics and quantity of reference objects, but when it comes to setting up mathematical models, many teachers are not confident. They always feel that this is only from the words of experts and are far away from the actual teaching In fact, mathematics itself is a model of teaching.First, to create a problem situation, so that students feel the formation of mathematics At present, although the new curriculum reform has been popular, but in teaching practice, you can still see the “knowledge and skills” and “Process Method ” traces of derailment, teach
