数学建模素养是高中数学六大核心素养之一,同时数学建模是利用数学理论去解决现实问题的一座桥梁,因此培养学生数学建模素养刻不容缓。学生问题提出能力的培养是世界各国都十分注重的话题,问题提出能力是创新型人才必备的技能,因此以“荷载与挠度”为例,基于问题提出教学来设计一节数学建模活动课,以期来培养学生的问题提出能力,发展学生的数学建模素养。Mathematical modeling literacy is one of the six core literacies of high school mathematics, and mathematical modeling is a bridge to solve practical problems by using mathematical theories, so it is urgent to cultivate students’ mathematical modeling literacy. The cultivation of students’ problem-posing ability is a topic that all countries in the world pay great attention to, and problem-posing ability is a necessary skill for innovative talents. Therefore, taking “load and deflection” as an example, a mathematical modeling activity course is designed based on the problem-posing teaching, in order to cultivate students’ problem-posing ability and develop their mathematical modeling literacy.
