本节课是新版教材人教A版普通高中课程标准实验教科书数学必修1第四章第4.3.2节《对数的运算》。其核心是弄清楚对数的定义,掌握对数的运算性质,理解它的关键就是通过实例使学生认识对数式与指数式的关系,分析得出对数的概念及对数式与指数式的 互化,通过实例推导对数的运算性质。由于它还与后续很多内容,比如对数函数及其性质,这也是高考必考内容之一,所以在本学科有着很重要的地位。解决重点的关键是抓住对数的概念、并让学生掌握对数式与指数式的互化;通过实例推导对数的运算性质,让学生准确地运用对数运算性质进行运算,学会运用换底公式。培养学生数学运算、数学抽象、逻辑推理和数学建模的核心素养。1、理解对数的概念,能进行指数式与对数式的互化;2、了解常用对数与自然对数的意义,理解对数恒等式并能运用于有关对数计算。
二、 讲评要有侧重,抓准学生的薄弱环节 教师备好试卷,备好学生之后,要切中要害分析学生在知识和能力方面的薄弱环节,找出考试中出现的具有共性的典型问题,针对导致错误的根本原因及解决问题的方法进行讲评,才能真正解决学生存在的问题,因此试题的讲评应该有所侧重,要有针对性。在讲评试卷时,并不一定按照试题的顺序逐题讲解,而是有针对性的将试题重新组合,侧重讲解,提高效率。 1.侧重抓难点 有了课前的统计数据,教师很容易把握住学生的难点所在,即那些具有代表性的错误试题,教师们可进行引导、分析讲解,由于学生具有迫切的求知欲望,课上学生也会表现得更为热情高涨。这样既节省了时间,又提高了效率,取得了较好的教学效果。

质疑问难,合作探究 1、文章是介绍沙子的知识吗? 明确: 有关恐龙灭绝的原因,原来本文的主角不是沙子,而是恐龙。 2、题目是《被压扁的沙子》,内容却恐龙灭绝的原因,题目《被压扁的沙子》是否偏离主题了?我们换成《恐龙是怎样灭绝的》会不会更好? 本文题目不但没有离题,还能提示读者,恐龙灭绝的“撞击说”所以产生,与被压扁的沙子的科学发现和科学研究密不可分此外,文题形象性强,容易激起好奇心,引起人们的阅读兴趣 3、恐龙灭绝的原因一直是学术界有争议的问题,因而产生两种学说“撞击说”“火山说”在探究恐龙灭绝的原因时,作者的观点是什么?他的观点以什么为依据,又是怎样推论出来的?
(一) 课标要求本单元所依据的课程标准是道德与法治课程标准 (2022年版) :第 四部分课程内容第四学段 (7-9年级) 国情教育中的:1. “了解世界正处于百年未有之大变局 ,具有初步的国际视野 , 了 解全人类共同价值的内涵 ,领悟构建人类命运共同体的意义 。 ”2. “ 以 “于变局中开新局 ”为议题 ,结合实例分析如何应对人类共 同面对的重大挑战 ,认识中国的发展离不开世界 ,世界的繁荣也需要中 国 。 ”3. “通过与中华优秀文化传统 、革命传统 、 国情教育等方面的关联 ,从真实的社会情境角度进行道德教育 ,强化学生的道德体验和道德实 践 , 旨在引导学生正确认识 自 己 , 以及个人与家庭 、他人 、社会 、 国家 和人类文明的关系 , 了解国家发展和世界发展大势 ,增强社会责任感和 担当意识 ,立志做社会主义建设者和接班人 。 ”
敬爱的老师们,亲爱的同学们,大家早上好。今天我国旗下讲话的主题只有一个字,那就是“爱”: 在当今这个世态炎凉的社会上,“爱”这个字似乎已经消失的无影无踪。 但是,依然有那么一群人在默默无声地将爱一份一份的传递下去。他们就是博爱学校的老师们。一个又一个孩子在那里得到了恢复:自闭症的孩子变得活泼起来,智力有限的孩子也在慢慢的痊愈…… 记得暑假中,我去了博爱学校陪他们上课。那些孩子们虽然有一些小小的调皮,但是却非常听话。 令我影象最深的,是一个小女孩,在体育课上,我陪着她一起抛接球,她马上就对我产生了好感。上楼梯的时候还用她的小手紧紧地拉着我的手。在他们身上,我看到了最原始的本性。
1、建立新员工入职管理制度。目前各公司对新员工方面的关注度偏低,容易造成新入职员工的流失。为此将建立新员工入职管理制度,对新员工指定两名入职导师帮带,一是企业文化导师,主要职责是从新员工入职的第一天开始就引导员工熟悉公司的企业文化,让其尽快融入公司;二是业务导师,主要职责是帮助新员工熟悉岗位工作流程,指导新员工逐步熟悉工作内容,适应公司工作要求。同时还要求两位导师每周跟新员工进行沟通,了解其对公司适应情况、对工作适应情况,并解答新员工提出的疑惑。对于新员工的导师我们要进行统一的培训,让其掌握引导新员工的方法与沟通方式,并给与鼓励性的补贴,年终评选优秀导师,并给予颁发证书及奖励。
总之,依法维护劳动者合法权益,是保障劳动者主人翁地位的前提,是充分调动劳动者积极性、创造性,使之成为改革开放和社会主义建设主力军的保证。也是促进劳动力资源合理配置,促进经济持续、快速、健康发展的需要。(三)课堂总结、点评★课余作业某企业由于生产任务较大,在未经劳动行政部门批准的情况下,厂长强行让部分职工延长劳动时间,每天加时工作,星期天也照常上班,不让休息。到月底,部分职工全月累计加班加点高达120小时,也不发加班工资。根据上述材料回答:你认为该厂的做法是否合法?为什么?劳动者依法享有哪些权利?该厂的做法侵害了劳动者的哪些权利?这些工人应当怎么办?★教学体会本节学习劳动者的权利和树立什么样的就业观等问题,与大家的生活联系比较密切。因此,在讲解过程中要通过大量的实例和对比,引导学生思考和讨论,将市场经济中的一些理论知识潜移默化的给学生。
