本节课以问题为主线,引导学生自主探究学习。主要研究参数对函数,图象的影响,引导学生有序参与,逐步深入探究,直至问题解决。在整个课堂活动中,学生均能积极主动地参与探究过程,使得不同层次的学生均能得到很好地发展。此外,本文在渗透学生恰当的数学思想方法、研究问题的一般方法方面都值得借鉴。 This section focuses on the problem and guides students to study independently. Mainly study the influence of parameters on functions and images, guide students to participate in an orderly manner, and gradually explore in depth until the problem is solved. Throughout the classroom activities, students are actively involved in the inquiry process so that students at different levels can develop well. In addition, this article is worthy of reference in infiltrating students’ proper mathematical thinking methods and general methods of researching problems.
