“不等关系”是苏教版必修5第三章第一节的内容.与以往教材设计不同,它以问题方式代替例题,目的是强化问题意识.这些问题可转化为不同类型的不等式.其实数学学习的过程就是数学发展的过程。纵观数学史可以发现,数学科学正是从现实世界以及自身理论体系中不断地提出问题,解决问题,从而得以前进、得以发展的.向学生揭示数学知识产生的背景, “Unequal relationship” is the content of the first section of chapter 3 of Supian version of Compulsory 5, which is different from the design of teaching materials in the past.It replaces the examples with questions, the purpose is to strengthen the consciousness of problems.These problems can be transformed into different types of inequalities In fact, the process of mathematical learning is the process of mathematical development. Throughout the history of mathematics, we can find that mathematics science is from the real world and its own theoretical system constantly put forward questions, solve the problem, so as to move forward and develop.Study to students the background of mathematical knowledge,
