“神奇的海洋馆”是小学五年级第三单元第二课内容,它是基于学生对画图程序的启动方法,窗口的组成,一些简单操作有了基本了解的基础之上,进一步探究绘图工具的使用方法。它是教材关于画图知识铺垫的延伸,并且贯穿着以后整个的画图知识教学,是学生能够顺利、快捷操作使用画图的基础之一,也是形成学生“了解熟悉——技巧掌握——综合运用”这一合理知识链的必要环节。教材目的是让学生学会前景色、背景色和掌握对封闭图形进行彩色处理的方法,重点是掌握利用画图的“用颜色填充工具“、“取色”工具对封闭图形进行彩色处理的方法。
知识与技能:掌握“用颜色填充工具”、“取色工具”的功能和使用方法。
过程与方法:培养学生自我探索、自主学习的能力以及创新能力,进一步提高学生的计算机技能。
情感态度、价值观:1、培养学生的审美能力和艺术情操,提高学生的表达能力。
2、培养学生积极进取、对知识不断探索的精神,激发他们对生活的热爱、对理想的追求……
教学重点:掌握“用颜色填充工具”、“取色工具”的使用方法。
教学难点:恰当、灵活运用“用颜色填充工具”、“取色工具”完成探究任务。
:本课采用的主要教学法是“演示法、探究法、任务驱动式教学法、启发式教学法、练习法”。
基于小学生形象思维的特点,照顾全体,我利用,采用讲演结合的方法帮助学生理解操作方法,激发鼓励学生自主探究、设计了给“海底世界”着色和“给福娃穿衣服”教学任务,启发学生思维,让学生在任务的驱动环境下,老师的引导下,同学的帮助下,完成操练任务、并设计扩展性练习让学生更好的去创造发挥,提高学生综合运用能力。
:自主探究,合作学习。

《醉翁亭记》是编排在语文版《义务教育课程标准实验教科书 语文》八年级下册第七单元的课文,是讲读课中的一篇。本教材从这一册开始,文言文采用集中编排方式(七年级是分布在各单元中的),这个单元课文还有借虚构的故事表现作者的社会理想的《桃花源记》,有表现作者伟大抱负的《岳阳楼记》,等等。
本单元的主要教学目标是:养成自觉诵读的习惯,熟悉一定数量的常用文言词语和文言句式,初步培养文言文的语感;让学生自主地学习,用探究的方式由表及里地理解文言文。
根据《初中语文课程标准》要求学生“能借助工具书阅读浅易文言文”,“具有独立阅读的能力……形成良好的语感。学会运用多种阅读方法。能初步理解、鉴赏文学作品,受到高尚情操与趣味的熏陶”,结合本单元教学目标和教材自身特点,我把本课教学目标定为:
1、知识目标:背诵并翻译课文,掌握相关文言实词;
2、技能目标:学习托物言志的写法并尝试在写作中使用;
3、情感目标:通过理解作者那种情趣,引导学生正确确立自己的志趣追求。
课文的篇幅短小,语句读起来琅琅上口,一方面容易引起学生的兴趣,一方面又可达到在多次诵读之后能基本了解课文大意,因而我把多形式诵读及当堂背诵定为教学重点;短文使用托物言志的写法,表述了作者的情趣,这对正在形成自己正确的人生价值取向的初二学生而言很有现实意义,因此我把如何理解短文的寓意定为教学难点。
我班学生经过初一一年的学习,已初步形成了一定的学习方法,对于文言文的阅读与学习掌握了一定的步骤,而且经过以往的朗读训练,他们很容易感受到短文的独特之处,容易从朗读中获得学习文言文的喜悦感与成就感,进而主动加入到背诵、解说、创作等学习活动中来。但由于本单元文言文首次采用集中编排方式,且所有的课文都有背诵要求,因此不断激发学习兴趣及成就感成为必要。
教师示范背诵,形成师生竞赛;通过互动板书设计,指导学生朗读,以读带动对课文的理解,养成良好的诵读文言文的习惯;用游戏法来进行背诵竞赛。
通过教学应使学生能当堂背诵短文,能运用已有的学习文言文的基本方法进行自主的学习。为此我设计的学习活动有:
1、多形式朗读课文,培养语感;
2、一对一互译课文;

《闭合电路欧姆定律》是高中物理第十五章《恒定电流》的第四节内容,是本章的重点,也是整个电学部分的一个重点。
本节内容是在学生学习了“欧姆定律”、“电功”等内容之后编排的,是分析和理解部分电路和全电路的交汇点。本节内容在教材中具有承上启下的作用,既是前面所学知识的巩固和深化,又为后继内容的学习做出了铺垫。
重点:闭合电路欧姆定律的内容及其理解
难点:电动势的概念;路端电压与负载的关系
知道电动势的概念;知道电源的电动势等于外电压和内电压之和;理解闭合电路欧姆定律及其公式,并能熟练地用来解决有关的电路问题;理解路端电压与负载的关系,知道这种关系的公式表达和图像表达,并能用来分析、计算有关问题;理解闭合电路的功率表达式,理解闭合电路中能量的转化。
培养学生观察、分析、解决问题的能力。
通过教学示范作用,培养学生实验探索和科学推理的物理思维品质,由此进一步认识物理思维方法;通过能力训练,培养学生创造性地学习的思维品质,能够变换、创设问题,从中理性地体会物理思维方法。
1、对“电动势”采用“类比”方法,并配以多媒体模拟分析,使学生的认识从感性上升到理性。
2、对“路端电压与负载的关系”,可采用“设疑——猜测——实验——分析——结论”的研究方法,以完成本环节的内容及从实验现象到理论总结,从实验技能到科学推理的教学任务。
3、讲练结合式:结合本节内容,给出相应的练习,随时发现学生的错误,并引导分析其错误原因,把教师的.主导作用与学生的主体作用结合起来,巩固强化有关知识。
根据教材特点和教学目标设计,教学中以了解、学习研究物理问题的方法为基础,掌握知识为中心,培养能力为主线,突出重点,突破难点为宗旨设计教学程序。
提出问题:各类型电源的电压是否相同?电源具有何种特性?如何去描述电源的特性?
演示实验:用伏特表直接测量蓄电池和干电池两端的电压。
结论:不同类型的电池两极间的电压不同,是由电源本身的特性决定的。
为描述不同类型的电源两极间电压的不同而引入——电动势。
(1)电动势:(e)
(用类比方法帮助理解,用多媒体模拟、辅助)
ⅰ、电动势的数值:
电动势的数值等于没有接入外电路时电源两极间的电压。
ⅱ、电动势的单位:伏特(v)
ⅲ、电动势的物理意义:(从能量角度分析)
电动势是描述电源把其他形式的能量转化为电能本领的物理量。
(2)闭合电路欧姆定律:
ⅰ、推导:(略)
ⅱ、闭合电路欧姆定律的内容:
闭合电路中的电流跟电源的电动势成正比,跟内、外电路的电阻之和成反比。
ⅲ、表达式:i=e/(r+r)
(3)路端电压跟负载的关系:
ⅰ、(设问)什么是路端电压?
外电路两端的电压叫路端电压。
ⅱ、路端电压随外电阻的变化情况:
(设疑——猜测——实验——分析——结论)
演示实验:改变外电路的电阻,观察路端电压的变化情况。
引导学生分析得出结论:外电路电阻增大时,电流减小,路端电压增大;外电路电阻减小时,电流增大,路端电压减小。
ⅲ、两种特殊情况:外电路短路和断路时的情况。
ⅳ、路端电压随电流变化的关系图像(为后续分组实验做准备)。
(4)闭合电路中的功率:
ⅰ、电源的功率;
ⅱ、电源内阻消耗的功率;
ⅲ、电源输出功率;
ⅳ、电源的效率;
分析课本例题;适当补充有关闭合电路欧姆定律及功率内容的习题(例题及练习题可以通过多媒体投影给出)。
