Teachers typically spend 80-90 percent of their time in class to teach the lesson. The lesson must be the same for all the students. Both the good and the bad students are taught the same content and are expected to learn the same. Students do their homework at home, where they must carry out the assignment without the guidance of a teacher.
Wouldn’t it be better to do the lesson at home and the homework in class? I think so!
And this is the proposal of Sal Khan, founder of “Khan Academy” graduate of MIT, former analyst for an investment fund, and now a true visionary of how technology can change education. Khan has developed more than 2,100 videos with lessons in not only arithmetic and calculus, but also finance and history. All are available online for free.
Students can view lessons on the Internet as many times as necessary before coming to class. The class then becomes the place where kids consolidate and apply what they learned. The novelty is that during class they don’t work on their own: the teacher and classmates (especially the most advanced) are available to help.
Doing homework in class and lessons at home is somewhat counter-intuitive for those of us who went to school in the 20th century, but it will be a reality in schools in the 21st century. “Watch. Practice, and Learn almost anything — for free” –this is the motto of the Khan Academy. It’s time to have one for Latin America.
