Khan Academy, which describes itself as a personalized learning resource, offers course content across a wide variety of disciplines and skill levels with a focus on fields such as mathematics, science and computing. In addition, Khan Academy offers courses in economics, finance, the arts and the humanities.
Khan Academy organizes the course content on its website across both learning discipline and skill level. For example, within mathematics, Khan Academy offers courses by specific discipline, such as algebra, geometry and arithmetic, as well as by age and school level, such as kindergarten through eighth grade, high school or college.
From its early focus on mathematics tutorials, Khan Academy has expanded into nearly every academic discipline with its video-based approach to instruction. As of 2015, courses cover everything from astronomy to medicine to art history. Courses are also offered in an expanding number of languages, transforming Khan Academy into a truly global learning platform.
Khan Academy features lecture-based and instructional videos that can be watched at home and then reinforced later in the classroom with problem-based coursework. This is the opposite of the traditional classroom, in which the instructional component comes from the teacher in the classroom and the homework happens at home.
