可汗学院 Khan college

　　可汗学院(Khan Academy)，是一个非盈利教育组织，通过在线图书馆收藏了3500 多部可汗老师的教学视频，向世界各地的人们提供免费的高品质教育。该项目由萨尔曼·可汗给亲戚的孩子讲授的在线视频课程开始，迅速向周围蔓延，并从家庭走进了学校，甚至正在“翻转课堂”，被认为正打开“未来教育”的曙光。[1]创始人可汗老师全名叫萨尔曼·可汗，孟加，自小课业优异，就读于麻省理工学院，大学双修数学和电机电脑工程，工作后读了哈佛的MBA课程，可汗老师什么都教，从数学，物理，化学，一直到理财人生，但他自己从来不出现在镜头前面。

Khan college(Khan Academy),Education is a non-profit organization,Through online library has more than 3500 of khan teacher's teaching video,To people all over the world free of high quality education.This project by salman khan · to relatives children teach online video courses start,To spread rapidly around,And from family went into the school,Even is"Flip class",Considered are open"The future education"dawn.[1] founder khan teacher full name salman khan ·,Meng and,Studies being outstanding,Enrolled in the Massachusetts institute of technology,University double studied mathematics and motor computer engineering,Work read a harvard MBA course,Khan teacher what all teach,From the mathematical,physical,chemical,Life has been to money,But he never appeared in front of camera.

　　教学特点 Teaching characteristics

　　1、可汗学院利用了网络传送的便捷与录影重复利用成本低的特性，每段课程影片长度约十分钟，从最基础的内容开始，以由易到难的进阶方式互相衔接。

1/Khan college use of the network transmission is convenient and video repeated use of the characteristics of low cost,Each period of course film length about ten minutes,From the most basic content began,From easy to difficult to advanced way to join each other.

　　2、教学者本人不出现在影片中，用的是一种电子黑板系统。其网站目前也开发了一种练习系统，记录了学习者对每一个问题的完整练习记录，教学者参考该记录，可以很容易得知学习者哪些观念不懂。

2/Teaching people, I do not appear in the film,With an electronic blackboard system.The site has also developed a practice system,Record the learner to each question the integrity of the practice record,The teaching reference this record,Can easily know what learners ideas don't understand.

　　3、传统的学校课程中，为了配合全班的进度，教师只要求学生跨过一定的门槛（例如及格）就继续往下教；但若利用类似于可汗学院的系统，则可以试图让学生搞懂每一个未来还要用到的基础观念之后，再继续往下教学，进度类似的学生可以重编在一班。

3/The traditional school course,In order to coordinate the progress of the whole class,Teachers only require students to cross a certain threshold(Such as pass)Will continue to teach;But if use similar to khan college system,May attempt to let students understand each future will use the basic conceptions later,Continue to teaching,Progress similar students can reweave is in class one.

　　4、在美国某些学校已经采用回家不做功课，看可汗学院影片代替上课，上学时则是做练习，再由老师或已经懂得的同学去教导其他同学不懂的地方这样的教学模式。

4/In the United States, some schools have adopted home don't do my homework,See khan college film instead of class,School is do exercises,Again by the teacher or the students have learned to teach the other students do not understand the place such teaching model.

　　5、可汗老师教学的方式，就是在一块触控面板上面，点选不一样颜色的彩笔，一边画，一边录音，电脑软体会帮他将他所画的东西全部录下来，最后再将这一则录下的影片上传到网上，一切就大功告成了。

5/Khan teacher teaching way,Even in a touch panel above,Click on the different color pastels,Part painting,Side recording,Computer soft experience to help him will he had painted things all recorded,The final will be a recorded film upload them on the Internet,Everything with respect to success.

　　6、他的教学视频，没有精良的画面，也看不到主讲人，只想带领观众一点点思考。

6/His teaching video,No excellent picture,Can't see the speaker,Just want to lead the audience think a little bit.

　　不足 shortage

　　不过，也有人指出了“可汗模式”的不足。迈阿密大学教育学教授沃尔特·斯卡达认为，可汗的教学方式存在“过度简化”的缺陷，“他总是利用特定例子来解释概念，如果人们遇到其他例子时，可能会糊涂……这表面上看是个小问题，却可能为以后的学习埋下隐患。”但不管怎样，可汗凭借一己之力，借助互联网这个平台，将“家庭教师”免费送给渴望知识的人，确实给了现代教育更多的启发。

but,Also some people pointed out"Khan mode"The shortage of the.Miami university education professor walter ska to think,Khan teaching methods exist"Over simplified"defects,"He always use specific examples to explain concepts,If people meet when other examples,May be confused……This on the surface is a small problem,But for the future study may be buried hidden trouble."But no matter how,Khan with on my own,With the Internet this platform,will"tutor"Free gift to the hunger for knowledge of the people,Indeed to the modern education more inspiration.

　　创始人介绍 Founder is introduced

　　萨尔曼·可汗成为“网络老师”，完全出于偶然。他出生在美国新奥尔良市，父亲是孟加拉裔，母亲来自印度。可汗很小的时候，父母就离了婚。他13岁那年，父亲因病去世，母亲从此成了他唯一的亲人。可汗从小就聪明好学，中学毕业时曾作为学生代表上台致辞。后来，他进入麻省理工学院，一口气拿下了数学学士学位、电子工程与计算机科学学士学位及硕士学位。此后，他又在哈佛商学院拿了一个工商管理学硕士学位。毕业后，“全能型”的可汗进入美国的一家基金公司，做着与教育毫不相干的工作。

Salman khan · become"Network teacher",By sheer chance.He was born in the United States the city of New Orleans,Father is Bangladesh origin,Mother from India.Khan at a very young age,Parents divorced.He is 13 years old,Father died due to illness,Mother from now on become his only family.Khan a smart studious,His graduation from middle school was used as a student representative address on the stage.later,He entered the Massachusetts institute of technology,With a bachelor's degree in mathematics/Electronic engineering and computer science bachelor's degree and a master's degree.Since then,He in the harvard business school and a master of business administration degree.After graduation,"refer"Khan to enter the United States a fund company,Doing nothing and education work.

　　现在，可汗每天制作3段视频。精通数学的他，可以仅凭记忆就制作出大部分数学辅导视频。但是，随着“可汗学院”所涉及领域的不断扩展，他意识到了充电的重要性。如果他对哪门想教的课不熟悉，就会自己先“恶补”一番。一次，可汗在制作一段视频前，花了两个星期来准备。“我打电话给所有认识的教授和熟人，对他们说，‘咱们出来喝杯酒，聊聊吧’。搜集了两周的材料后，我对这个问题终于有了清晰的理解，这才开始动手制作视频。”在他看来，网络教学的另一个好处是能得到即时的反馈，让他可以根据网友的反馈，不断完善视频。“如果观众没能理解，或者发现了其中的错误，我会重新制作一遍。”

now,Khan made every day 3 period of video.He is proficient in mathematics,Only by memory will produce most of the math tutoring video.but,as"Khan college"In the field of expanding,He realized the importance of the charge.If he wants to teach classes which door not familiar with,Will we"Boning up on"a.a,Khan in making a video before,Spent two weeks to prepare."I call with all the professors and acquaintances,Said to them,‘Let's come out for a cup of wine,Chat chat’.Collect the two weeks after the material,On this question I finally have a clear understanding,It began to make a video."In his view,The network teaching another advantage is to be able to get instant feedback,Let him can according to users feedback,Constantly improve video."If the audience could not understand,Or found the mistake,I will to make it again."
