“先学后教”教学模式,顾名思义,就是学生的“自主学习探究”环节与教师的“引导指导学习”环节有效衔接、相互融合的教学方式。高中数学学科教学中,“先学后教”教学模式有着深入广泛的应用。一、“先学”环节,应注重学生主体特性的有效发挥“先学”环节,是学生自主探究、自主学习的活动过程。这一过程中,学生良好学习潜能的发挥,自主学习能力的培养,是做好“先学”活动的前提和条件。因此,在开展“先 ”The first to teach “ teaching mode, as its name implies, is the teaching method of effective connection and integration between students ”autonomous learning and exploration “ link and teachers ”guiding and guiding learning “ link. In high school mathematics teaching, the teaching mode of ”learning first and then teaching“ has extensive and extensive application. First, ”first learning “ link, should pay attention to the effective play of the main characteristics of the students ”first learning “ link, is the process of student independent exploration, independent learning activities. In this process, the development of students’ potential for good learning and the development of their own learning ability are the prerequisites and conditions for doing well in ”learning first“ activities. Therefore, carry out ”first
