人教A版高中数学必修一函数y=Asin(ωχ+φ)教学设计（1）
本节课选自《普通高中课程标准实验教科书数学必修1》5.6.2节 函数y=Asin(ωx+φ)的图象通过图象变换,揭示参数φ、ω、A变化时对函数图象的形状和位置的影响。通过引导学生对函数y＝sinx到y＝Asin(ωx+φ)的图象变换规律的探索,让学生体会到由简单到复杂、由特殊到一般的化归思想；并通过对周期变换、相位变换先后顺序调整后,将影响图象变换这一难点的突破,让学生学会抓住问题的主要矛盾来解决问题的基本思想方法;通过对参数φ、ω、A的分类讨论,让学生深刻认识图象变换与函数解析式变换的内在联系。通过图象变换和“五点”作图法,正确找出函数y＝sinx到y＝Asin(ωx+φ)的图象变换规律,这也是本节课的重点所在。提高学生的推理能力。让学生感受数形结合及转化的思想方法。发展学生数学直观、数学抽象、逻辑推理、数学建模的核心素养。
第九周国旗下讲话稿：关注弱势人群，你我同行
各位老师，各位同学：大家早上好！我今天讲话的题目是《关注弱势人群，你我同行》。相信大家乘坐公交车或地铁时都会听到车上传出这样的声音：尊老爱幼是中华民族的传统美德，请给有需要的人士让座。是啊，在我们的生活中，有这样一群“有需要的人士”，他们或在智力方面有缺陷，或在沟通方面有障碍，又或是丧失了某种习以为常的能力，人们称他们为“弱势群体”。对弱势群体的关爱，应该遍布社会的每一个角落。当我们穿过那些豪华的楼堂馆所时，是否关注到那些背负着沉重的工具准备去修建城市好不容易挤上公交车的农民工？当我们穿着美丽干净的服装走在大街上，是否关注到那些那些清扫工、那些修鞋修下水道卖烤地瓜的人们？还有那些时不时出现在我们眼里的残疾人，我们是否能充分理解尊重他们？个人的力量是微弱的，但如果大家一起行动，一点关爱可能温暖他人的一生！此时此刻，我想起了曾看到过的一名网友对于老人扶不扶事件的看法。他说：“世界上那么多老人，难道每一个都要我去扶吗？这不是我的义务！我开心了我就扶，不开心我就不扶，你还能怎样？把我抓进监狱吗？真好笑！”
第十九届推普周国旗下讲话稿范文精选
大家早上好!今天国旗下讲话的题目是《人人都讲普通话，处处盛开文明花》。每天早上，当我们进入校园，彼此相见时，都会用普通话互道一声问候，那甜甜的问候让我们心中涌起了一种无比亲近的感情;在学习中、在交谈时，我们感觉只有用普通话，才能使我们彼此顺畅地沟通。语言是一个民族的声音，从大处讲，推广普通话，说好普通话，是我们祖国屹立于世界民族之林的需要;从小处说，它是不同地域、不同文化背景中的人与人沟通交流的需要。我们爱祖国，我们爱讲普通话，这应该是我们每一个炎黄子孙的共同的心愿。五千年文化的沉淀，五千年华语的传承，泱泱大国，龙的子孙，每一个中国人的脸上，正扬着华夏文明的灿烂。随着祖国的日益昌盛，做中国人，讲普通话，这是每一个挺起脊梁的中国人的神圣宣言。学好普通话，讲好普通话，这是我们每一个中国人责无旁贷的职责。随着祖国的强大，甚至连许多外国人也纷纷跨入了学汉语的行列。作为一名中国人更应该为此感到骄傲：普通话作为汉语成了友谊的桥梁，沟通的纽带。
大班主题《我长大了》说课稿
在一次常规的身高体重测查后，我把前一次的测查结果和这次的测查结果同时展示，引起了小朋友对自己成长的关注，渴望知道自己小时候的故事。为此，我设计了这个主题系列活动，一方面满足孩子们的心理需要，促进自我意识的发展；另一方面让孩子了解长辈对自己的关怀、爱护，改善孩子只会享受长辈对自己的爱，而不懂得会报的心理状态。纲要中要求：应“引导幼儿对身边常见事物和现象的特点、变化规律产生兴趣和探究的欲望。”我认为选择此教材有一定的阶段性和必要性，它符合《纲要》的精神：“教育活动内容既适合幼儿的现实需要，又有利于其长远发展；既贴近幼儿的生活，又有助于拓展幼儿的经验和视野……”
《我长大了》幼儿园大班说课稿
2、目标定位：根据大班幼儿年龄特点及实际情况以及布鲁纳的《教育目标分类学》为依据，确立了认知、能力、情感等方面的目标，融合了语言、科学、社会、艺术领域的整合。目标为：(1)通过各种方法引导幼儿发现自己的成长与变化。(2)激发幼儿欣赏自己的成长，展示自己的能力，树立自信心。(3)乐于与同伴交流、分享自己成长的快乐。(4)让幼儿尝试制作个人成长册，发展幼儿的精细动作。(5)让幼儿体会父母的辛苦、关心，增进亲子之情。 根据目标，我把活动重点定位于：感受“我长大了”，主要是发现自己成长与变化。通过观察、比较小时候的照片和用品、播放录像、交流分享、展示自己，使活动得到深化。活动的难点是：根据人的成长过程进行排序、制作个人成长册，主要是通过自主操作，在动手的过程中培养手部肌肉的灵活性和提高排序的能力，对自己的成长充满了期待。在目标定位上，树立了目标的整合观、科学观、系统观，各领域内容有机联系，相互渗透，注重综合性、趣味性、活动性，寓教育于生活、游戏中。因此，我作了以下活动准备：(1)空间准备：幼儿小时候的照片、衣物、用品布置于墙上，桌椅呈同字型便于评价和集中。(2)物质准备：“人的成长过程”图片，卡片纸、彩笔、彩纸、剪刀、胶水等美工材料与工具若干，已制作本领树的树干，小时候的录像(或小中班在园的录像)，胎儿的生长发育以及新生儿的养育的录像。(3)知识准备：幼儿向家长了解爸爸妈妈的故事及自己小时候的趣事，观察各个阶段自己成长的照片，熟悉人物主要特征。

中班科学教案：吃西瓜
目标：1、感知、探索西瓜的特征。2、通过比较、品尝，体验新品种无籽西瓜的优点。[评：目标2体现了科技、发明与人们之间关系密切的观点。]准备：1、外形各异的普通西瓜及其他瓜果若干。2、无籽西瓜若干。3、餐巾、点心盘人手一份；刀、抹布各一。4、课前请幼儿洗净双手。过程：一、用故事引出“怎样吃西瓜”的问题[评：以有趣的故事引出课题，既能启发幼儿联系自己的经验，又能激发幼儿讨论的兴趣。] 教师讲述故事《猴王吃西瓜》，提问：1、猴王是怎样吃西瓜的？2、你们是怎样吃西瓜的？
中班科学教案：颜色对对碰
2、通过在活动中引导幼儿仔细观察，鼓励幼儿大胆尝试记录实验结果，培养幼儿的好奇心。 【活动准备】 １、物质准备： A.一瓶黄颜色的水。 B.每组三个透明的小缸，分别装有红、黄、蓝三种颜色、及棉签等 C.记录材料每人一份，小盘若干，瓶子若干。 2、经验准备：认识颜色。 【活动过程】 一、情境导入：以看魔术表演来激发幼儿学习的兴趣。 1）师：今天，张老师当一次魔术师，给大家变一个小魔术，请仔细观察！ 这瓶水是什么颜色的？（黄色） “好，小朋友看清楚了，魔术开始！千万不要眨眼睛哟！” 教师摇晃瓶子,变变变。 师：“我们一起来喊一二三，一，二，三变成什么颜色拉？”（绿色）
中班科学教案：小球站稳了

XX--2018学年第一学期第八周国旗下讲话稿：秋意寒 勤锻炼
XX--2018学年第一学期第八周国旗下讲话稿：秋意寒勤锻炼尊敬的老师们、亲爱的同学们：大家好！今天，我国旗下讲话的题目是《秋意寒勤锻炼》。秋季的到来，给南方的天气增加了几分寒意，这个季节，没有了夏日的骄阳，正是锻炼身体的好时机。参加秋季体育活动，不仅能够锻炼身体增强体质，而且还能提高身体的抗寒能力和增强抵抗各种疾病的能力。秋季体育锻炼，由于肌肉不断收缩，呼吸加快，新陈代谢旺盛，身体产生的热量增加。同时还增强了大脑皮层的兴奋性，使体温调节中枢灵敏、准确地调节体温，提高人们的御寒能力。在锻炼中接受阳光的照射能够促进身体对钙、磷的吸收作用，有助于骨骼的生长发育。尤其对正在长身体的同学们来说，多参加户外锻炼更为重要。
XX-XX学年第1学期第9周国旗下讲话稿：团结就是力量
尊敬的领导、老师，亲爱的同学们：早上好！今天我发言的主题是：团结就是力量！曾经有人问闻名世界的指挥家卡拉扬：“你是如何指挥世界著名的交响乐团？”卡拉扬说：“我只强调三个音来使我的乐队变成团队。首先强调，‘起音’；起音不齐，乐曲就乱。第二个是个人的‘专业音’，不管是吹喇叭的还是打鼓的，要表现出自己专业上认为是最好的、最出色的音。第三个音则是‘团队音’，当你打出自己的专业音之后，还要考虑到整体，是不是会成为干扰别人的音。”卡拉扬说的多好呀！我们的学校，我们的班级，我们的学习，我们的生活不也都需要这样的团队精神吗？如果把我们的班级比作一只乐队，那么共同的集体目标就是我们的“起音”，发挥每个人的才能是我们的“专业音”，同心协力，团结奋斗就是我们的“团队音”。
学校教师教研工作计划
一、指导思想 素质教育的发展，其根本目的是培养学生的全面发展，提高学生的创新思维及创造能力。其核心就是创新能力、实际的动手能力和观察能力等科学素质的培养。由于科学课程承担着培养小学生科学素养的重任，科学课程的内容和课程结构都与学生的生活和经验紧密结合，为学生的终身发展提供必备的基础知识、基本技能和良好的情感发展与价值观。科学课程以创新精神和实践能力为核心，重视发展学生搜集处理信息的能力、自主获取新知识的能力、分析解决问题的能力、交流与合作的能力，其地位在整个小学教育中是越来越重要。因而，学好科学这一课程也显得越来越重要。
教师教学工作考核制度
１、教案检查制度： 为了消除无教案上课现象，年级部每月进行一次教案检查登记，根据教案数量考核课时津贴，根据备课数量和质量考核当月教案得分。平时考核按10分制。根据备课格式的规范性，备课内容、板面及书写综合评分，上等记为9-10分，中等记为5-8分，下等在5分以下，上等人数不得超过30%。教务处或教研室开学和期末要对教师教案进行检查，并评选出本期优秀教案。 ２、作业检查制度： 年级部每月对任课教师的作业布置和批改情况作检查登记，并评定当月得分，按10分制记录。作业率在10％以下记1分，作业率在10%至20%记2分依此类推。但批改不认真的要在基本分上酌情扣分，作业率＝作文一次按两次统计。体育音乐课允许无作业，此项评分将根据两操一课活动的开展情况，平时的各种活动开展情况和成绩记录、资料收集等项目进行考核，学期末由年级部和教务处考核评分。

Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角）left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分，只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition
