Academy influences
has an analysis that the success of "Khan University" is a protest and challenge for the current educational system. According to the statistics of the YouTube website, the Khan's course is also popular than free online courses made by his alma mater Institute of Technology. Many universities online courses, but it is the process of teaching the processes of classes, emphasizing "teaching"; and Khan's teaching video, highlights the process of "learning". There is a media that "Khan Mode" makes people have questioned many "non-two truths" of higher education - if only experts are the best teacher, every hour is about one hour, the most suitable ... American education There is also a video teaching class, but the effect has been in a bad, and the students have a limited computer, and the communication with teachers is also limited. Nowadays, two schools in California, California have been tried in the fifth grade and seventh grade teaching video. The students watch video self-study at home, and the teacher answers questions in the classroom, and counseling students to complete their homework. Khan said, this is what he hoped: "My goal is to make a video course that everyone is willing to follow. Seeing people entering the university with the help of the 'Khan College', I really have achieved good results. It is too happy. "The next goal of Khan is to make all the courses from kindergarten to high school in the next five years, as well as some university courses such as computer science and electronic engineering.
Not enough

If people encounter other examples, they may be confused ... this The surface is a small problem, but it may be a hidden danger for future learning. "But no matter what, exploiting the power of the Internet with the help of the Internet, the" family teacher "is given to the people who are eager for knowledge, indeed gave it. Modern education more inspiration.
