Unit4 Topic2 Section A教学设计2023-2024学年仁爱科普版英语八年级上册

一、内容和内容解析 1.内容 反比例函数的概念 2.内容解析 反比例函数是初中函数学习的重要内容.通过反比例函数概念的学习，既加 深对函数概念的理解，又加强对反比例变化规律的认识.从函数角度看，当一个 变量变化时，另一个变量随着它的变化而变化，而且对于这个变量的每一个确定 的值，另一个变量都有唯一确定的值与之对应：从反比例变化规律看，在变化过 程中，这两个变量的乘积始终为定值.成反比例函数的两个变量的乘积是定值是 反比例函数的特征 通过对现实生活和数学中问题的分析，发现变量间的反比例关系，归纳得出 反比例函数的概念，再运用反比例函数的概念对数学和现实生活中的问题进行分 析，通过具体实例，确定反比例函数的解析式，是本节课的研究思路。 基于以上分析，本节课的教学重点是：理解反比例函数的概念 二、目标和目标解析 1.目标 (1)认识反比例函数的概念 (2)能够根据已知条件，确定反比例函数的解析式。 2.目标解析 达成目标(1)的标志是：通过对实际问题和数学问题的分析，抽象概括得出反 比例函数的概念，知道自变量和对应的函数值成反比例的特征。 达成日标(2)的标志是：能根据问题中的变量关系，确定反比例函数的解析式 UNIT 4 Our World Topic2 How can we protect ourselves from the earthquake？ Section A I.Teaching objectives Knowledge objectives 1.Enable to read the new words and phrases earthquake,strike,province,missing,lose one's life,protect sb.from. ask sb.for help 2.Enable to use the comparative and superlative of adjectives.
