本文以苏科版初中数学九年级上册第一章第4节“用一元二次方程解决问题”的第1课时为例从教材分析与学情分析,教学目标分析,教法与学法,教学过程等几个方面阐述教学设想。一、教材分析与学情分析一元二次方程是中学数学的主要内容,在初中数学中占有重要地位,其中一元二次方程的实际应用在初中数学应用问题中极具代表性,它是一元一次方程应用的延续,又是二次函数学习的基础,同时也是研究现实世界数量关系和变化规律的重要模型。
In this paper, Su Ke version of junior high school mathematics ninth grade on the first chapter fourth section “a quadratic equation to solve the problem ” the first lesson from the teaching material analysis and the analysis of the situation, teaching objectives, teaching and learning method , Teaching process and other aspects of teaching ideas. First, the textbook analysis and analysis of academic situation Unary quadratic equation is the main content of high school mathematics, plays an important role in junior high school mathematics, of which the practical application of quadratic equations in the junior high school mathematics application is extremely representative, it is a once a The continuation of the application of the equation is also the basis of quadratic function learning and an important model for studying the relationship between quantity and change in the real world.
