1.经历过程,体验建模。《课标》中指出:“要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和应用的过程。”数学概念的形成,数学方法的积累,数学规律的总结都需要学生能从数学对象中抽象出数学模型。如,在学习一元一次方程解应用题中建立“利润率”模型,教师可联系生活实际,让学生到市场中做调
Experience the process, experience modeling. “Curriculum Standard” states: “From the students' existing life experiences, let the students experience the process of abstracting practical problems into mathematical models and interpreting and applying them.” “The formation of mathematical concepts, the accumulation of mathematical methods, The conclusion of the law of mathematics requires that students abstract the mathematical model from mathematical objects. For example, in learning a one-time equation solution application problem to establish ”profit rate " model, teachers can contact the actual life, so that students do the market to adjust
