22、说课稿一、教材分析本节课选自人教版高一数学（必修一）第二单元 2.2.2对数函数及其性质第一课时。对数函数是重要的基本初等函数之一，是指数函数知识的拓展和延伸. 它的教学过程，体现了“数形结合”的思想，同时蕴涵丰富的解题技巧，这对培养学生的观察、分析、概括的能力、发展学生严谨论证的思维能力有重要作用本节课也为后面进一步探究对数函数的应用及指数函数、对数函数的综合应用起到承上启下的作用。二、学情分析学生前面已经学习了指数函数，用研究指数函数的方法，进一步研究和学习对数函数的概念、图像和性质以及初步应用，启发引导学生进一步完善初等函数的知识的系统性，加深对函数的思想方法的理解。教学过程中，发挥大多
23、数学生动手能力较强的特点，让学生自己通过列表、描点、连线画对数函数图像。这样也利于对对数函数性质的理解。三、教学目标1.知识目标： 让学生掌握对数函数的概念，能正确描绘对数函数的图象，掌握对数函数的性质.2.能力目标：通过对对数函数的学习，培养学生观察，思考，分析，归纳的思维能力.3.情感目标：培养学生勇于探索的精神，让学生主动融入学习四、教学重点和难点重点：在理解对数函数定义的基础上，掌握对数函数的图象和性质。难点：对数函数性质的应用。五、教法与学法说教法教学过程是教师和学生共同参与的过程，启发学生自主性学习,教师主导,学生为主体,根据这样的原则和所要完成的教学目标，我采用如下的教学方法：
24、(1)启发引导学生思考、分析、实验、探索、归纳。(2)采用“从特殊到一般 ”、 “从具体到抽象”的方法。(3)体现“对比联系 ”、 “数形结合”及“分类讨论”的思想方法。(4)多媒体演示法。说学法教给学生方法比教给学生知识更重要，本节课注重调动学生积极思考、主动探索，尽可能地增加学生参与教学活动的时间和空间，我进行了以下学法指导：(1)对照比较学习法：学习对数函数,处处与指数函数相对照。(2)探究式学习法：学生通过分析、探索、得出对数函数的定义。(3)自主性学习法：通过实验画出函数图象、观察图象自得其性质。(4)反馈练习法：检验知识的应用情况，找出未掌握的内容及其差距。这样可发挥学生的主观能动
