With the rapid development of information technology, especially from the Internet to the mobile Internet, it has created a way of life, work and study that spans time and space, and fundamentally changed the way of knowledge acquisition. Teaching and learning are not limited by time, space and place, and the channels of knowledge acquisition are flexible and diverse.
Salman khan, a Bangladeshi American, founded the Khan Academy in the United States. Khan has produced more than 2,300 teaching videos about mathematics, physics, chemistry, biology, astronomy and other subjects, and used video technology to reform traditional teaching methods, providing free quality education to the whole world, creating an "educational myth" that a teacher can attract tens of millions of students with a computer. There are 56 million primary and middle school students around the world watching his teaching videos, and 6 million students log on to the website every month.
Khan's teaching video highlights the process of "learning" and triggers the teaching mode of "flipping the classroom". The traditional teaching mode is that teachers give lectures, assign homework and let students go home to practice and do homework. "Flip classroom" means that students study Khan teaching videos at home, and the classroom becomes a place for interaction between teachers and students, including answering questions, applying knowledge and teamwork, so as to achieve better educational results. Research shows that this personalized learning method can greatly improve students' learning efficiency. Two schools in California, USA, have tried out the teaching video of Khan Academy in the fifth and seventh grades. Students watch videos at home and teach themselves. Teachers answer questions in class and help students finish their homework. 20 13 of the curriculum of Khan Academy will be adopted by more than 20 public schools in the United States. 20 12 in April, Time magazine named 100 people who influenced the world in 20 12, and salman khan ranked fourth. He is recognized as a superstar in the field of global teaching.
