1问题的提出不久前,笔者所在数学科组举办了一次骨干教师示范课,执教老师选择的是高三年级数学基础最薄弱班级,选择在此班上公开课目的也是为了调动后进学生学习数学的积极性.此节课的课题是《二元一次不等式(组)与简单的线性规划问题》,执教
A problem raised Not long ago, the author’s mathematics group held a key teacher demonstration class, coaching teachers choose the third grade is the weakest foundation of mathematics, choose to open class in this class is also intended to mobilize the enthusiasm of students to learn later The subject of this lesson is “Binary Inequalities (Group) and Simple Linear Programming Problems”, coaching
