英语教学extension

英语发音浊化问题[s]后面是清辅音[t], [k], [p]时，则对应地变成发[d], [g], [b]的浊辅音。如：stop[stɔp]念[sdɔp]，school[sku:l]念[sgu:l],spring[spring]念[sbring]

英语音标的规则 音标中“s”后有t，k，p等辅音时等要浊化（如：extension 【iks'ten∫ən】中s后有个t） t—（此时读成）——d k—（此时读成）——g p—（此时读成）——b 如experience...

extension一般指延展，延伸，加长的意思，比较倾向与平面的伸展；而expansion指膨胀，扩张，有点倾向于立体全面增大。探究的一般过程是从发现问题、提出问题开始的,发现问题后,根据自己已有的知识和生活经验对问题的答案作出假设．设计探究的方案,包括选择材料、设计方法步骤等．按照探究方案进行探究,得到结果,再分析所得的结果与假设是否相符,从而得出结论．并不是所有的问题都一次探究得到正确的结论．有时,由于探究的方法不够完善,也可能得出错误的结论．因此,在得出结论后,还需要对整个探究过程进行反思．探究实验的一般方法步骤：提出问题、做出假设、制定计划、实施计划、得出结论、表达和交流．科学探究常用的方法有观察法、实验法、调查法和资料分析法等．观察是科学探究的一种基本方法．科学观察可以直接用肉眼,也可以借助放大镜、显微镜等仪器,或利用照相机、录像机、摄像机等工具,有时还需要测量．科学的观察要有明确的目的；观察时要全面、细致、实事求是,并及时记录下来；要有计划、要耐心；要积极思考,及时记录；要交流看法、进行讨论．实验方案的设计要紧紧围绕提出的问题和假设来进行．在研究一种条件对研究对象的影响时,所进行的除了这种条件不同外,其它条件都相同的实验,叫做对照实验．一般步骤：发现并提出问题；收集与问题相关的信息；作出假设；设计实验方案；实施实验并记录；分析实验现象；得出结论．调查是科学探究的常用方法之一．调查时首先要明确调查目的和调查对象,制订合理的调查方案．调查过程中有时因为调查的范围很大,就要选取一部分调查对象作为样本．调查过程中要如实记录．对调查的结果要进行整理和分析,有时要用数学方法进行统计．收集和分析资料也是科学探究的常用方法之一．收集资料的途径有多种．去图书管查阅书刊报纸,拜访有关人士,上网收索．其中资料的形式包括文字、图片、数据以及音像资料等．对获得的资料要进行整理和分析,从中寻找答案和探究线索．

巩固拓展，可以Consolidation and extension

extension → 侧重于平面的伸展，延伸expansion → 侧重于立体的膨胀

对于英语教学讲解，我们课堂上分析讲解时需要以教案来辅助。下面是我给大家整理的英语教学案例分析范文，供大家参阅!

A Brief Instruction to the topic of“What should I do”

Good afternoon,everyone. My name is ______. I’m from -------Primary School .Today I’m going to talk about the topic” ________________”I will divide the instruction into seven parts：they are Teaching material Analysis, Teaching aims, Teaching emphasis, Teaching difficulties, Teaching methods, Teaching aids and Teaching procedures.

Part 1 Teaching material analysis

This period is from Unit …. of ….b Oxford English. First of all,I’d like to talk about my understanding about this lesson.We have learned …..in Unit ….We have also learned how to _______ in last two units.Today we are going to learn __________________.So this unit links with a special meaning of Unit ___and Unit ___.This period is the first lesson of Reading.The main idea of the topic is how to express their problems and ask for advice.We are going to learn the ways to deal with problems and stress in following lessons.So this period is very important in this unit.

And according to the contents and the fact of the Ss, I establish the following three teaching aims of this period.

Part 2 Teaching aims

1.Aims of the knowledge:

(1)The first one, students can listen, read, say and spell the the following words: ______________

(2) The second one : students can listen, read, say and write the following daily exprssions:________________ To know the spelling of some words and usage of some phrases.

Part 3 Teaching emphasis

1.To help Ss communicate with each other using the new sentence pattern.

2.To enable Ss to study in groups and co-operate skillfully.

3. To develop Ss’interest in English. I think, it’s the most important .

Part 4 Teaching difficulties

I think the most difficult point is to make sure the students…

1.To make sure the Ss use the sentence pattern correctly. Lead them to mix the old and new knowledge to ask and answer.To foster Ss’abilities of innovation.

2.To finish the task by themselves.

Part 5 Teaching methods

In this topic,I will use five-step Teaching Method , Task-based Method,Communicated Method, Group Cooperate method. .I design some tasks to help the students learn.I think if I want to improve the students’ oral English,I should give them enough chances to practice and I will use pair work,group work to let the students take an active part in all kinds of activities.That is “Learning by doing,learning by using”.Let the students be the masters of the class teaching,thus,student-centered teaching method is well shown.

Part 6 Teaching aids

I will use some pictures, words and sentence cards, a tape recorder and the computer to help me achieve the aims.

Part 7 Teaching procedure

Step Ⅰ.Lead-in

The purpose is to arouse the students’interest of study.

In order to attract the Ss’ attention and construct an surrounding of learning English, I let the Ss sing an English song and play a game ”” At the same time,the game can help Ss review the knowledge ,

Step Ⅱ.Presentation

The purpose is to develop the skills of skimming and how to gain the main idea of the articles.

1 The substance of language is communication and the environment of communicatiog is life. So when I present the sentence pattern”_________”,I first show ________ ,teach the sentence. Then show my own photo of _________,Ss ask and guess, In this way, I can attract SS’attention, Encourage Ss to ask Qs with the new knowledge.

2 Most of the Ss have learned the sentence pattern:___________,so I design a task for SS to help …. And teach the new language point :___________ Meanwhile show the sentences on the CAI.

3 After some practice by asking and answering, I present the next language points.___________ Finnaly, I’ll let the SS do pair work to consolidate them.

Step Ⅲ.Practice

1. In order to make sure the Ss master the teaching material, Let them Listen to the tape and answer some question about “True”or“False”.

2.Ask students to read the articles again and read it in roles. Pay attention to their pronunciation and intomation.

And it is also a ready work for the next step. Give a model then do some extension.

Step Ⅳ.Extension.

The purpose is to develop the skills of retelling with the key words

1 Set a task, Try to give a model with the good student. .

2 Divide the Ss into groups of 4 people .Each one would make a new dialogue according to the scenes that CAI provided. Using the phrases and the sentence pattern that we have learned. Find out which group is the best.

3.Encourage students to say something about themselves.

Task based Method is used here to develop the Ss’abilities of communication and their abilty of co-operation will be well trained.

Step Ⅴ.Summary and homework

The purpose is to give the students a clear idea of how to express their problems and revise the articles.

1.Ask students to revise the words and phrases

During my teaching，I’ll try my best to get my class alive and encourage the students to talk with each other in English.I think the general aim of English teaching is to improve the ability of using English. And I’ll use this to guide my teaching. Make the students to love the interesting English and the lovely English teacher.

Thank you!
