So, who appeared in front of the camera?
answer: "no one."
These films are all just lines and words, accompanied by Mr. Ke Han's "narration". The way this "Mr. Cohen" teaches is to click on different colored pens on a touch panel, draw and record at the same time, and the computer software will help him record all the things he draws, and finally upload this recorded video to YouTube, and everything will be done. Calculate the cost, a Camtasia video recorder only costs $2, the bamboo piece of the touch panel Wacom only costs $8, and the SmoothDraw3 he uses is a free version, so recording, each film is about ten minutes, just in line with the time limit of YouTube.
I think it's very interesting that I watched several YouTube movies recently, all of which attracted people in this way. Some of them draw on the whiteboard, so they can see the painter's hands and head, and some of them have no sound, only music. If these actions are regarded as a kind of "blog", then we really don't know how to "classify" them-they are definitely not words, and although they are spread by audio-visual videos, they are very different from ordinary audio-visual blogs. They don't show their faces, and they usually don't exaggerate things by their faces or voices. The same feature of these special "blogs" is that they always "organize" what they have to say well. They can lay out a theme, which may be a very common thing, in a very organized way by using lines and words, so that netizens can nod their heads frequently! Sometimes I am so moved that I have to freeze it and pull it back to "watch it again!" It can be seen that this "shooting method" has some ghostly attraction.
According to Wikipedia, "Teacher Kehan" is called Salman Khan, of Indian origin. His parents divorced when he was young, and his father died at the age of 13. He was raised by a single mother, but he was excellent in his studies since he was a child. Later, he went to MIT, where he studied mathematics and electrical and computer engineering, and then he studied for a master's degree in electrical and computer engineering. After work, he went to Harvard for an MBA. Just now he was still at work. His teaching was simple and straightforward, and he taught well. Other relatives also came to beg him to "save" their children, so Mr. Cohen felt that he might as well record it as a YouTube video for everyone to watch on the Internet, and so he recorded it all the way. Mr. Kehan's films on YouTube have not grown much every month, but they have grown steadily by 1% and 1%. As a result, Mr. Kehan has become more and more famous and his films have been watched by more and more people. As a result, in 29, Mr. Kehan actually quit his job in the financial sector (they wrote this way, but it is also possible that he was cut in salary and laid off in the financial turmoil). Therefore, Mr. Kehan is 33 years old and married. A few years ago, after the media disclosure, Mr. Cohen also received a public welfare donation from a well-known company, 37Signals, and a well-known venture capitalist, John? Toure, it's interesting that they all donate only a little, such as $1,, because investors can see that Mr. Kehan's "difficult to classify" feature can only be done by himself, so he is only willing to pay enough money so that Mr. Kehan can make videos at home without going to work and continue to slowly expand his "Kehan Teacher College".
Mr. Cohen thinks that when teaching on the Internet, people don't have to stand up and write it on the board like him for the audience to see, and there will be a kind of intimacy like "tutoring" with Mr. Cohen at your side, and there will be no oppression or threat from the teacher. The reporter went to visit some children. For example, the 11-year-old child said that he had learned basic arithmetic easily from Mr. Cohen, and the dentist said that Mr. Cohen could win the Nobel Prize. Some college students say that they have to study calculus for the whole semester in college class, and it took him only a few hours from Mr. Cohen to get a comprehensive understanding!
At present, Mr. Cohen has recorded more than 1,516 films on YouTube. By the end of last year, the films of "Mr. Cohen College" had an average of 35, new views every day, with a total of 16 million views. He also had nearly 2, fans on faceboook. It is a small "one-sided hegemony." Moreover, since Mr. Cohen resigned from his job, his "mission" has become clearer-he hopes to produce high-quality free teaching materials for everyone in the world. He has recorded all his videos separately, made them into DVDs and sent them to poor villages in other countries in Asia, Latin America and Africa "for free" (just I don't know how they can understand English). What's next? But Mr. Han is not satisfied. He hopes to cover "more topics". In fact, he hopes to cover "every topic" of life!
here comes the fun. The success of Mr. Cohen reminds me of some other feelings-
If Mr. Cohen takes out these teaching films and then he says that he wants to cover "every theme" of life, I find that in the eyes of professional so-called "education experts", there may be the following problems:
First, he does not use the traditional "online teaching": the so-called "online teaching" Make a cool system? Because they emphasize that there are two things that can be done online: first, let the teacher "truly" stand in front, so the teacher sometimes draws a picture in front in three dimensions, and can stop at any time, go backwards and move to the next chapter or the previous chapter, but Mr. Han has turned the classroom into a "tutor" and has not clearly divided chapters. Second, there should be a lot of "interaction" in online teaching. After listening to a paragraph, you have to write a few questions to interact with it. Although Mr. Han has some interactive parts, the main teaching is actually completely interactive because of YouTube.
Secondly, he just touched the embarrassing part of "free education": Mr. Kehan's practice is controversial, which can't be blamed on Mr. Kehan. Because Mr. Kehan just graduated from MIT, some people compare it with the well-known MIT open teaching, but in fact, Mr. Kehan still holds the copyright of his teaching materials, but the price is only "free", so Mr. Kehan is somewhat open. If Mr. Cohen is not an "open course", what is he?
Third, the "system" of his classes is not strong enough: at present, Mr. Kehan shoots one in the east and one in the west, but it is not a system, which is a "taboo" for any "college". After all, the most important thing is that a cow skins several layers, and the courses can never be finished, so that he can continue to go on. I shot them for 2 years old ... So, these films can only be called "demonstration" films. After watching them on the Internet, people really want to continue watching them. As for the part of "continuing to watch", Mr. Han still has to spend a lot of time to "catch up".
Fourth, it is difficult for him to establish a "brand" feature: although painting is a very distinctive thing to teach, it may be difficult for others to speak it as well as Mr. Ke Han, but frankly speaking, anyone can imitate this "feature" if they put their heart into it! Maybe someone's editing skills are better than Mr. Cohen's, and then Mr. Cohen will be "compared". Therefore, Mr. Cohen didn't show his face from beginning to end, which may be a "failure", because it is difficult to establish a long-term relationship with only one voice and a pen!
In other words, although Mr. Kehan seems to have brought a new force to online teaching, he is difficult to be classified. No matter which category he falls into, Mr. Kehan seems to have some "missing corners".
However, he lets 35, people come up to watch it every day!
everyone likes what he shoots!
In a recent chat, a female friend said that her boyfriend complained that she had changed, and he said that he preferred her "original taste". However, she also said something that is worth pondering. She said that although her boyfriend likes her original appearance, he often says, what kind of clothes should you wear for a figure like you.
It's like parents telling their children that it doesn't matter. Be true to yourself and choose your favorite subject! But at the same time, I told him that you were better at math since childhood, so you can refer to the practices of those sciences.
once we start to "classify" something and then "compare" it's not "original". I find that sometimes, some people are not clear about their own position? Even being scolded "You don't know where you are"? But in fact, that kind of positioning is called "original taste".
Mr. Cohen's teaching method can subvert the whole digital teaching by one person. Online teaching has spent billions of dollars in the past ten years, precisely because of his "original taste". It is precisely because other people have to classify themselves at the beginning, so even if the original idea is very good, they unconsciously lose their "original flavor" when walking. But Mr. Kehan didn't actually want to compare himself with other courses. After all, he just wanted to teach his relatives' children well from the beginning. He just wanted to do what other courses couldn't do, not to compete with other courses. Therefore, he didn't "classify" at first, and then he didn't "classify" and became a "four unlike", so he became an unprecedented "Mr. Kehan".
All the people in the world have the original flavor, and they insist on refusing to be classified. Only those who can't be classified normally are truly pure original flavor!
