So if you use one system for practice, you get credit in the other system and don’t have to review topics you already know. Fortunately, the two systems share mastery status for each skill. The previous World of Math system coexists with a new mastery system based on courses. Khan Academy is in the middle of a mastery system upgrade.
Next week, I’ll look at how they relate to discrete math topics. This week, I’ll go over the topics available on Khan Academy. These gaps can slow down further learning, since math success in later courses depends on knowing the skills taught in previous courses. The idea is to fill in “ swiss cheese gaps” in knowledge that often accumulate when learning math in school. But Khan Academy can also help adults review the fundamental skills necessary to learn more advanced math. These skills map to school curricula like the US Common Core, so that when students learn something on the site, it translates to success in the classroom. Khan Academy’s math program is designed to help children and young adults learn and practice a particular set of math skills.
