《初中数学课程标准》中强调:“预设和生成在教学过程中几乎是同时存在的,它们如影随同,既是矛盾的,又是统一的”。随着教育改革的进一步深入,这两个相对独立,又形影相伴的概念也一步步地走进了我们课堂教学中。但是,在教学过程中我们又难免产生纠结,那就是预设和生成毕竟相对独立,预设增多或减少,生成有时会朝着它相反的方向,变得减少或增多。那么怎样做才能让它们和谐共生呢?一、精心预设,准备生成教师走进课堂之前,研究制定教学方案,是一件最为复杂,
“Junior high school mathematics curriculum standards,” emphasizes: “Predecession and generation in the teaching process almost simultaneously, they are the same shadow, both contradictory and unified.” With the further deepening of education reform, these two concepts that are relatively independent and accompany each other have also gradually stepped into our classroom teaching. However, in the process of teaching, we inevitably produce tangles, that is, the preset and the generation are relatively independent, the preset increases or decreases, and the generation sometimes decreases or increases in the opposite direction. So how can we make them harmonious symbiosis? First, elaborate, ready to generate Teachers into the classroom before the study and formulation of teaching programs is one of the most complex,
