“教而不研则愚,研而不教则虚。”为进一步提高教学质量,促进高效课堂。
2021年12月2日,山西省阳泉市第十一中学高一数学组进行了教学研讨活动。本次活动的主要内容:研讨高一数学必修第一册第四章《指数函数的图象与性质》。研教材、研学情、研目标、研重点、研难点、研教法,老师们积极讨论,各抒己见,畅所欲言,达成共识。
","type":1},{"audio_music_id":0,"source":0,"text":"教学分析
(一)教材分析:函数是高中数学的一个重要组成部分,在初中所学的一次函数,二次函数,反比例函数等基本初等函数的基础上,指数函数是高中生学习的第一个具体的函数,通过对指数函数的学习可以进一步深化对函数概念的理解,也为后面学习对数函数,幂函数,三角函数等函数打下基础。
(二)学情分析:高一的学生在研究过一次函数,二次函数等基本初等函数的基础上,借助列表、描点、作图,通过观察图像对指数函数基本性质有直观的认识,并从函数的角度研究讨论函数性质的一般方法。用“情境引入——实践探究——思维拓展——课后反思——强化训练”的模式,在学习中激发学生的求知欲,对知识深入理解。
(三)教学目标
1、了解指数函数的实际背景,体会建立一个函数的基本过程和方法。
2、运用数形结合,理解指数函数的概念,图像,性质。
3、培养学生严谨的数学思维,提高学生知识迁移意识。提升学生的逻辑推理,直观想象,数学运算等数学核心素养。
(四)教学重点与难点
1、运用数形结合的方法从具体到一般概括,研究指数函数的概念及其性质。
2、建立指数函数的概念,探究指数函数的性质
(五)教学方法 “情境式”教学模式,“合作探究”教学模式

","type":1},{"audio_music_id":0,"source":0,"text":"传统教学中,学生习惯于接受现成的结论(比如直接告知形如y=ax,a>0,且a≠1的函数叫指数函数),在运用知识解决一些已经提出的问题,教学的重点是训练解决问题时的技能技巧,造成了技能虽强,但创造力不够的状况.在教学中,应为学生提供像“指数函数的概念”这种基于发现的更有价值的数学活动.从实践来看,结合课程内容的实际要求和学生的年龄特点,适时、适度地引导学生从日常生活中和具体情境中发现、提出数学问题,进而分析和解决问题更利于发展他们的“四基”与“四能”.
发现问题和提出问题是现今学生比较缺失的能力,教师应有意识地引导学生学会从数学的角度去观察生活,对生活现象进行数学思考,通过对现象的梳理、概括、提炼,并用数学的方式思考“是什么?为什么?怎么样?有什么用?”等问题.如本节课应让学生思考:y=ax是函数吗?它是怎样刻画变化规律的函数模型?如何运用它研究问题?等等.这个过程不仅是学生运用已有知识、技能、思想方法和活动经验进行数学抽象的过程,更是融入了六大核心素养(数学抽象、逻辑推理、数学建模、直观想象、数据分析、数学运算)的要求,有效支撑了数学学科素养的发展。
