高中化学《酸、碱、盐在水溶液中的电离》

一、考题回顾

二、考题解析

【教学过程】

环节一:课堂导入

【提出问题】在中学的时候就做过这样一个实验:把连有小灯泡和电源的两个金属片插入不同溶液中,发现有的溶液可以使小灯泡发光,有的则不能,哪些溶液可以使小灯泡发光呢?

【学生回答】氯化钠溶液,烧碱溶液,盐酸溶液……都可以使小灯泡发光。

【提出问题】为什么氯化钠溶液能够导电?一起来学习“酸、碱、盐在水溶液中的电离”。

环节二:新课教学

1.以NaCl溶液为例,思考溶液为什么会导电?

【提出问题】NaCl晶体由哪些粒子构成?

【学生回答】Cl-和Na+。

【提出问题】NaCl晶体加入水中后会发生什么变化?如何表示这一过程?

【学生回答】将NaCl加入水中,在水分子的作用下,Cl-和Na+脱离NaCl晶体表面,进入水中,形成能够自由移动的水合钠离子和水合氯离子。NaCl发生了电离。这一过程可以用电离方程式表示如下:

NaCl=Cl-+Na+

(教师结合上图、学生回答进行讲解,示意图可以通过大屏幕呈现或者让学生看教材也可以。)

2.酸、碱、盐的电离

【提出问题】根据NaCl的电离方程式,写出HCl、HNO3、H2SO4在水溶液中发生电离的方程式,思考,如何从电离的角度概括酸的本质?

【学生回答】HCl、HNO3、H2SO4在水溶液中发生电离的方程式:

HCl=H++Cl-

HNO3=H++NO3-

H2SO4=2H++SO42-

HCl、HNO3、H2SO4都能电离出H+,因此,从电离的角度认识酸:电离时生成的阳离子全部是H+的化合物叫做酸。

【提出问题】试着写出NaOH、Ca(OH)2、Ba(OH)2、KOH的电离方程式,思考如何从电离的角度概括碱的本质?

【学生回答】NaOH、Ca(OH)2、Ba(OH)2、KOH的电离方程式:

NaOH=Na++OH-

Ca(OH)2=Ca2++2OH-

Ba(OH)2=Ba2++2OH-

KOH=K++OH-

NaOH、Ca(OH)2、Ba(OH)2、KOH都能电离出OH-,因此,从电离的角度认识碱:电离时生成的阴离子全部是OH-的化合物叫做碱。

【小组活动】列举常见的盐,思考如何从电离的角度定义盐?

【学生回答】

小组回答①:根据CuSO4、NaNO3、MgCl2等的电离方程式,能够电离出金属阳离子和酸根阴离子的化合物叫做盐。(错误答案,该设置的目的是引导学生认识到铵根离子当做金属阳离子对待。)

小组回答②:(NH4)2SO4、NH4Cl也是盐,但是电离出的阳离子不是金属阳离子。

小组回答③:盐能电离出的阳离子有金属阳离子、也有铵根离子,电离出的阴离子都是酸根离子。

……

【教师总结】由此可知盐是能够电离出金属阳离子或铵根离子和酸根阴离子的化合物。

环节三:巩固提高

【提出问题】从电离的角度判断Na2SO4、Na2CO3、NaHCO3是不是盐,它们在水溶液中的电离方程式如何书写?

解析:Na2SO4、Na2CO3、NaHCO3的电离方程式:

Na2SO4=2Na++SO42-

Na2CO3=2Na++CO32-

NaHCO3=Na++HCO32-

教师需要讲解NaHCO3属于酸式盐,电离时,电离成金属阳离子和酸式酸根离子。

环节四:小结作业

请学生回答本堂课的收获有哪些,可以回答学到了哪些知识,也可以回答学习的感受。

布置作业:思考NaHSO4的电离方程式该如何书写?酸式盐的电离方程式的书写有什么规律没有?

【板书设计】

【答辩题目解析】

1.从电离的角度分析酸、碱、盐的组成。

【参考答案】

从电离的角度来看:在水溶液中电离出的阳离子全部都是H+的化合物叫做酸;在水溶液中电离出的阴离子全部都是OH—的化合物叫做碱;在水溶液中能够电离出金属阳离子(或铵根离子)与酸根阴离子的化合物叫做盐。

2.概念原理的知识在讲解过程中常用的教学策略有哪些?

【参考答案】

概念原理知识在课堂教学中的方法策略:

(1)突出证据的作用,帮助学生形成新概念。

(2)关注学生的原有认识,建立概念间的联系。

(3)制造认知冲突,促进学生转变错误概念。

(4)抽象概念形象化,减少学生的学习障碍。

(5)优化推理过程,发展学生抽象思维能力。

高中数学《直线与平面平行(2)》

一、考题回顾

二、考题解析

【教学过程】

(一)导入新课

回顾直线与平面平行的判定定理。请学生思考,若已知直线与平面平行,能得到什么结论。

引出课题。

(二)讲解新知

出示如下图形,请学生观察并思考:如果一条直线与一个平面平行,那么这条直线与这个平面内的直线有哪些位置关系?学生通过观察能够看出,这条直线与这个平面内的任意一条直线都没有公共点,所以它们只能平行或异面。

(三)课堂练习

求证:如果三个平面两两相交于三条直线,并且其中两条直线平行,那么第三条直线也和它们平行。

请学生写成“已知”、“求证”的形式,并画出图形进行证明。

(四)小结作业

小结:回顾直线与平面平行的性质定理。

作业:思考——如果三个平面两两相交于三条直线,并且其中两条直线相交,那么第三条直线和这两条直线有怎样的位置关系?

【板书设计】

2.本节课是如何进行导入的?

【参考答案】

本节课我采用复习导入的方式。在学习本节课之前,学生已经学习了如何判断一条直线与一个平面平行,通过复习的方式,即巩固了之前所学,也使得教材中“若已知直线与平面平行,则能得到什么结论”这一问题的提出显得更为合理。因此我采用了这样的导入方式。

Teaching reflection

【答辩题目解析】

1.请做一个简单的自我介绍。

1. Please introduce yourself briefly.

【参考答案】

各位老师好,我来自XX。我在2019年完成了XX学院的文学学士学位,在学校主修英语翻译。大学期间,我从事过兼职英语教学,曾经在培训机构当英语教师,也在农村学校做过支教教师。学生们非常喜欢我的课,这激发了我对教学工作的热爱,也使我立志成为一名老师。

我喜欢在闲暇时间看书,喜欢读各种各样的书,包括教育、文学、医学等。我最喜欢的书是罗恩·克拉克写的《罗恩老师的奇迹教育》。这本书用各种真实的教学实例来说明教师应该对学生有很高的期望,从而使学生取得巨大的进步。这本书在我的兼职教学经历中给了我很大的启发,对我今后的教学也有一定的指导意义。

在我的业余时间,我也喜欢做一些运动,如慢跑,瑜伽,和我的朋友打羽毛球。

我的教育背景和工作经验让我具备了作为一名教师的基本条件。我期待着探索新的领域,提高自己的技能。

【Suggested version】

Hi, I am from XX. I completed my Bachelor of Arts degree from XX College, in 2019. I majored in English translation. During college, I engaged in part-time English teaching, being an English teacher at a training institution and a volunteer teacher at a rural school. The students like my classes very much, which stimulates my love for education and make me aspire to be an educator.

I like reading during my leisure time. I like reading different kinds of books, covering education, literature, medicine, etc. My favorite book is The End of Molasses Classes authored by Ron Clark. This book is very attractive with various authentic teaching examples to illustrate that teachers should have high expectations of students, thereby students can make astonishing progress. This book has inspired me a lot during my teaching part-time experience, and will guide me in teaching in the future.

In my spare time, I also like doing some sports, such as jogging, yoga, and playing badminton with my friends.

My qualifications and work experience make me a suitable candidate to be a teacher. I am looking forward to exploring new dimensions for the further development of my skills.

2.谈谈怎么激发学生学习英语的动机?

2. Do you have any ways to motivate students to learn English?

【参考答案】

作为一名老师,最艰巨的任务之一就是用正确的方式激励学生。我想和大家分享我的想法。

首先,激发学生内在动机的一种有效方式是让课堂交际性更强。小组活动和翻转课堂都是常用的增强课程交际性的好方法。

第二,让课堂变得有趣是提高内在动机水平的可靠途径。我们可以尝试以下策略,比如学生们喜欢电影、杂志和流行音乐,我们可以把流行文化引入课堂,利用它们作为听力、阅读材料或进行词汇学习;或者在课堂上和学生玩游戏,游戏是教授词汇和使用语法结构的非常有效的方法。

除此之外,给予及时的反馈很重要,比如恭维和鼓励,以及批评。教师也不一定是反馈的唯一来源,我们可以鼓励同伴反馈和自我评价。

当我们成功地激发了学生的内在学习动机时,即使他们离开了校园,也能帮助他们获得成功。

【Suggested version】

One of the toughest tasks a teacher can have is to motivate students in the right way. I'd like to share my ideas.

Firstly, one way to encourage students’ intrinsic motivation is to make class communicative. Group activities and a flipped class are both great ways to attain the goal.

Secondly, making class fun is a surefire way to raise intrinsic motivation levels. Here are some strategies we can try: first is to invite pop culture into class, since students love movies, magazines and pop music. We could use them in class for listening activities, reading activities or to learn new vocabulary. The second way is to play games with students. They’re highly effective ways to teach vocabulary and practise grammatical structures.

What’s more, it’s important to give positive feedback, like compliments and encouragement, as well as criticism. Teachers don’t have to be the only source of feedback for students. We can encourage peer feedback and self-evaluation.

After teachers successfully inspire the motivation of students, we set them up for success even after they leave classrooms.
