The incredible YouTube

Gordon Ramsay, a very famous Scottish Chef, has many famous restaurants around the world. And majority of American  might know him through a TV show called Master Chef. However, he is not only a chef or TV celebrity, but also a successful charity ambassador who has devote himself to protecting shark. Long before, he has initiated a campaign in order to encourage restaurants not use shark fin and people not to eat shark fin. The video showing a sequence of how sharks were killed, and why people want to eat shark fins, why government didn't prohibit this criminals, spread widely via YouTube. 

This is the video:

According to the data provided by YouTube, I have been shocked by the number of view count. Almost 2 million people have viewed this video, which didn't include the people who have viewed the relevant videos. Gordon Ramsey must will be very happy that his campaign has been largely promoted by the YouTube.

Compared to many other social network tools, YouTube has one huge advantage that videos could show information vividly and efficiently.  The threshold for reader is very low, in other words, people don't need many prerequisite knowledge to watch many videos. Therefore, even kids could be obsessed about YouTube. 

But the disadvantage is also very obvious that the creators usually could give the enough feedback for all the viewer. We could also say it's unnecessary for the interaction between the viewers and video creators, which is the big obstacle for educators who want to use YouTube as their teaching objectives. Usually, YouTube is just the tertiary information source like a introduction video insert in a PowerPoint. 

Does it possible that you can use YouTube just many other online learning course? The answer is positive.  

We can use Gordon Ramsay as an another example. 

The following two Gordon Ramsay Home Cooking TV show could tell you how to make a delicious and simple food at home:

We could easily find many similar video tutorials from YouTube. The video creators record all the learning objectives in the videos. Some argues that learners still can't get the enough feedback from the educators. Or we could conclude that we could not make sure the teaching quality and learning process. Thus, I reckon that the " Reversible video frequency teaching systems" is a new kind of important teaching method of distant learning.
