  • 新人教版高中英语必修2Unit 3 The Internet-Listening &Speaking&Talking教案一

    Listening and Speaking introduces the topic of “ask about online habits”. Many middle school students have been surfing the Internet for many years, but what they do with the Internet and how much time they spend every day may not be very clear to themselves, nor to other students. This section allows students to investigate their peers' Internet use, which is conducive to their mutual understanding and understanding of the Internet. It can also help them reflect on their own online behavior, learn from other people's good online habits, and get rid of their bad online behavior.The listening text of this section is an investigation interview. The investigators interview specific groups with the same questions to obtain information, so as to understand their views, practices or attitudes on this issue. There are two specific questions: “how much time do you spend online every day? What do you usually do online?”. The answers of the three respondents provide rich and different information, and achieve the purpose of the investigators. The oral discourse structure of survey interviews generally includes greeting and explaining the purpose of the interview, presenting the interview questions and the respondents' answers. Listening and Talking introduces the theme of “choosing the right application ". Listening text is a conversation between Laura and Xiao Bo. In this part of listening, “oink”; “piggy bank” may cause the students' hearing comprehension limitation. Oink refers to sound word and pig's sound.

  • 人教版新课标高中物理必修1弹力教案2篇

    一般情况下,凡是支持物对物体的支持力,都是支持物因发生形变而对物体产生弹力。所以支持力的方向总是垂直于支持面而指向被支持的物体。例1:放在水平桌面上的书书由于重力的作用而压迫桌面,使书和桌面同时发生微小形变,要恢复原状,对桌面产生垂直于桌面向下的弹力f1,这就是书对桌面的压力;桌面由于发生微小的形变,对书产生垂直于书面向上的弹力f2,这就是桌面对书的支持力。学生分析:静止地放在倾斜木板上的书,书对木板的压力和木板对书的支持力。并画出力的示意图。结论:压力、支持力都是弹力。压力的方向总是垂直于支持面而指向被压的物体,支持力的方向总是垂直于支持面而指向被支持的物体。引导学生分析静止时,悬绳对重物的拉力及方向。引导得出:悬挂物由于重力的作用而拉紧悬绳,使重物、悬绳同时发生微小的形变。重物由于发生微小的形变,对悬绳产生竖直向下的弹力f1,这是物对绳的拉力;悬绳由于发生微小形变,对物产生竖直向上的弹力f2,这就是绳对物体的拉力。

  • 人教版新课标高中物理必修2功率教案2篇

    1.用CAI课件模拟汽车的启动过程。师生共同讨论:①如果作用在物体上的力为恒力,且物体以匀速运动,则力对物体做功的功率保持不变。此情况下,任意一段时间内的平均功率与任一瞬时的瞬时功率都是相同的。②很多动力机器通常有一个额定功率,且通常使其在额定功率状态工作(如汽车),根据P=FV可知:当路面阻力较小时,牵引力也小,速度大,即汽车可以跑得快些;当路面阻力较大,或爬坡时,需要比较大的牵引力,速度必须小。这就是爬坡时汽车换低速挡的道理。③如果动力机器在实际功率小于额定功率的条件下工作,例如汽车刚刚起动后的一段时间内,速度逐渐增大过程中,牵引力仍可增大,即F和v可以同时增大,但是这一情况应以二者乘积等于额定功率为限度,即当实际功率大于额定功率以后,这种情况不可能实现。

  • 人教版新课标高中物理必修2平抛运动教案2篇

    (五)平抛运动规律的应用例1:一架老式飞机在高出海面45m的高处,以80m/s的速度水平飞行,为了使飞机上投下的炸弹落在停在海面上的敌船,应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。分析:对于这道题我们可以从以下几个方面来考虑:(1)从水平飞行的飞机上投下的炸弹,做什么运动?为什么?(2)炸弹的这种运动可分解为哪两个什么样的分运动?3)要想使炸弹投到指定的目标处,你认为炸弹落地前在水平方向通过的距离与投弹时飞机离目标的水平距离之间有什么关系?拓展:1、式飞机在高出海面45m的高处,以80m/s的速度水平飞行,尾追一艘以15m/s逃逸的敌船,为了使飞机上投下的炸弹正好击中敌船,应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。2、在一次摩托车跨越壕沟的表演中,摩托车从壕沟的一侧以速度v=40m/s沿水平方向向另一侧,壕沟两侧的高度及宽度如图所示,摩托车可看做质点,不计空气阻力。(1)判断摩托车能否跨越壕沟?请计算说明(2)若能跨过,求落地速度?

  • 人教版新课标高中物理必修1摩擦力教案2篇

    l.知识与技能:(1)知道摩擦力产生的条件。(2)能在简单问题中,根据物体的运动状态,判断静摩擦力的有无、大小和方向;知道存在着最大静摩擦力。(3)掌握动磨擦因数,会在具体问题中计算滑动磨擦力,掌握判定摩擦力方向的方法。(4)知道影响到摩擦因数的因素。2.过程与方法:通过观察演示实验,概括出摩擦力产生的条件及摩擦力的特点,培养学生的观察、概括能力。通过静摩擦力与滑动摩擦力的区别对比,培养学生分析综合能力。3.情感态度价值观:在分析物体所受摩擦力时,突出主要矛盾,忽略次要因素及无关因素,总结出摩擦力产生的条件和规律。二、重点、难点分析1.本节课的内容分滑动摩擦力和静摩擦力两部分。重点是摩擦力产生的条件、特性和规律,通过演示实验得出关系f=μN。2.难点是学生有初中的知识,往往误认为压力N的大小总是跟滑动物体所受的重力相等,因此必须指出只有当两物体的接触面垂直,物体在水平拉力作用下,沿水平面滑动时,压力N的大小才跟物体所受的重力相等。

  • 人教版高中政治必修1第九课走进社会主义市场经济教案

    法律手段:制定和运用经济法规,包括经济立法、经济司法活动等行政手段:采取强制性的行政命令、指示、规定等运用举例:我国一些地区遭遇突如其来的“禽流感”,禽类养殖户损失惨重。国家采取了对疫区封锁,对疫区的养殖户进行经济补贴,以及国家出资统一对疫区进行消毒等措施进行防治,并规定任何人不得将家禽带出疫区,违者追究法律责任。请结合材料说明在防治“禽流感”、发展禽类养殖的过程中,我国政府分别采取了哪些措施教师分析:对疫区养殖户进行经济补贴体现经济手段;对违反规定者追究法律责任,体现法律手段;对疫区进行封锁体现行政手段。(四)反思总结,当堂检测。教师组织学生反思本节课的主要内容(参照板书),进行总结。设计意图:对本节课的内容进行小结,学生的概括过程也是检验学生对本节课理解程度的过程。再次明确学生是学习的主体,并能够发现,问题解决问题。

  • 人教版高中政治必修3第五课文化创新精品教案

    3.社会实践对文化创新的决定作用社会实践对文化创新具有两个方面的重要作用:(1)社会实践是文化创新的源泉实践,作为人们改造客观世界的活动,是一种有目的、有意识的社会性活动。人类在改造自然和社会的实践中,创造出自己特有的文化。离开了社会实践;文化就会成为无源之水、无本之木,人们不可能从事任何有价值的文化创造。◇本课小结:1.关于本课逻辑结构的宏观把握:文化创新的源泉和作用这一问题,教材分三个层次展开论证:一是不尽的源泉,不竭的动力;二是巨大的作用,深刻的意义;三是呼唤文化创新的时代。教材运用辩证方法从文化创新的源泉和作用展开论述。即社会实践是文化创新的源泉,文化创新又推动社会实践的发展和促进民族文化的繁荣。教材关于文化创新的途径问题,从三个层次展开讲述:第一个层次是“继承传统,推陈出新”;第二个层次是“面向世界,博采众长”;第三个层次是“坚持正确方向,克服错误倾向”。

    一、说教材《说“木叶”》这篇文学论文位于统编版高中语文必修下册第三单元。本单元对应课程标准的学习任务群是“实用性阅读与交流”,人文主题是“探索与创新”,语文素养是“学习阅读知识性读物,理清文章思路,学习阐释说明、逻辑推理的方法,体会语言的严谨准确,发展科学思维”。《说“木叶”》提出了中国古典诗歌为何用“‘木叶’而不用‘树叶’、又由‘木叶’发展为‘落木’的疑问”,继而分析了“木”字的两个艺术特征,解决了上述疑问,阐发了中国古典诗歌语言的暗示性。二、说学情高一年级下学期的学生已经接触过不少实用性论说类文本,例如统编版九年级上册《论教养》《谈创造性思维》等文章。本学段的学生已经掌握了“论点、论据、论证”的相关知识,并且发展了一定的逻辑思维能力,这为《说“木叶”》的讲授提供了学习支架。但《说“木叶”》这篇文学论文,篇幅长达三千字,使用了专业术语,运用大量诗词举例,这些是给学生阅读造成困难的原因。

  • 《说“木叶”》说课稿(一) 2021-2022学年统编版高中语文必修下册

    这五个问题,主要从学情出发,由浅入深,从感知到理论,培养学生的鉴赏能力。第三环节:延伸探究、展示成果(多媒体显示)走出文本,引入课外同类文学现象,让学生能够触类旁通,举一反三,把教材作为一个例子,让学生在深入的文学鉴赏中再次获得语言的审美。同学们初步掌握了文学语言具有暗示性的性质后,还需巩固、提升鉴赏能力!这里我采取的方法是:引导学生认真阅读文本,经小组合作探究后,得出本组的鉴赏成果并加以展示,这里重在培养学生的理解能力和分析综合能力。问题是:1、 请结合下面三首词的意境,选用残红、落红、乱红填空。2、 阅读下面这些句子,理解“燕”在词语中的暗示意义。该环节充分体现了 “ 教师为主导,学生为主体”的原则。老师的适时点拨,让学生的鉴赏思路更加清晰。学生通过合作探究,理解能力和分析综合能力得到了提升。
