At TED 2011, Salman Khan came to present the Khan Academy, a carefully structured collection of over 2,000 educational videos. The Khan Academy is experiencing a notable success with some 1 million visitors a month who watch between 100 and 200 thousand videos a day, says its creator.
Salman Khan started incidentally. Financial analyst for a pension fund, he was teaching math remote cousins via the internet and decided to take a few lessons on YouTube, more as a complement to the course he gave them than anything else. His cousins were quite happy to have less to bother to go to lessons and be able to follow their own pace. Gradually, public videos on YouTube have met success and praise ... So much so that some teachers have begun to use these courses in videos as homework in the evening and offer classroom exercises. Gradually, "The teachers used technology to humanize the classroom," said Salman Khan.
By success, Salman Khan quit his job and founded a non-profit Khan Academy. The video courses are not sufficient, the association has developed interactive exercises associated with each course. After following the video lectures, students are invited to the associated interactive exercises: these are repeated until they have had 10 in a row, a sign that they understand the concept.
For Salman Khan, the system is very different from what happens in the classroom, where classes alternate with exercises before any checks come measure knowledge acquired. Each student managed differently control, but it accomplished, everyone goes to learn the following notion. In class, the idea is that you advance quickly, as the program, so much so that many students may find themselves adrift because they hurt a similar concept or gaps have accumulated, making difficult learning a concept based on previous knowledge. With courses and exercises the Khan Academy, children learn and assimilate the concepts at their own pace. "The traditional model penalizes experimentation and failure, and does not expect mastery. We encourage you to experiment. We encourage you to fail. But we do expect you to succeed, "proclaimed Salman Khan.
KahnAcademy Map of knowledge learning is organized around a tree of knowledge which leads students towards ever more advanced knowledge. We share the basics of math, to go to arithmetic and algebra ... Maps to visualize her in Advanced concepts.
Some pilot classes in Los Altos have stored their textbooks to work with Khan Academy. Each student works at their own pace and the teacher has access to a dashboard that shows him the progress of each. He can see what you have learned, those on which students work and of course, those with which students encounter difficulties, allowing it to intervene. For each student, the teacher has access to a detailed dashboard of student work: measuring the time spent, the exercises performed, video views ... It also has access to a summary of the knowledge of its class, enabling it to see the progress of all students (you can also easily manage a class through the Khan Academy). By introducing the personalized attention, we find out the different rates of learning of children, says Salman Khan. There is also a concept that once understood and known, often the result is easier. "A lot of effort to humanize the class focuses on the relationship between student and teacher. For us, the humanization depends on a relationship between the student and a profitable learning time with the teacher. In traditional teaching, the teacher spends his time giving lectures, exercises and controls. Maybe 5% of their time actually happened to sit next to students to explain something and really work with them. With us 100% of their time devoted perhaps to that! "
Salman Khan is already dreaming of a world class, where children learning a concept would help those who are trying to learn it. A development that will surely be the next version of the Khan Academy ... At a time when some American states seek to develop lessons in computers to reduce the costs of education, such as the International Mail reports, it is certain that many those who will look at initial results of the online Academy. However, Salman Khan insists his dream is not to disappear teachers, but rather have them focus on their mission: to help them learn!
