一、数与代数领域的教学创新在新的课程理念下,在数与代数领域进行初中数学创新教学设计,要关注如下几个方面的变化与发展:(一)突出从实际问题情境中抽象出代数模型的过程初中生的学习对象已由具体的数发展为抽象的数学符号,他们将研究刻画现实世界数量关系的方程、不等式和函数。内容的呈现可以采用“问题情境——建立模
I. Teaching Innovation in the Field of Number and Algebra Under the new concept of curriculum, the design of mathematics innovation teaching in junior high school in the fields of numbers and algebra should pay attention to the following aspects of change and development: (1) Highlighting the abstraction from the actual problem situation The Process of Algebraic Model The junior high school students’ learning objects have been developed from concrete numbers into abstract mathematical symbols. They will study the equations, inequalities and functions that describe the quantitative relationship in the real world. The presentation of the content can be used ”problem situation - to establish the model
