Key Points:
The traditional academic model groups students together by age and perceived ability and all learn at the same pace. No matter what grade a student receives on a test , the whole class will then move on to the next subject, a more advanced subject that's going to build gaps
in knowledge
Sal Khan believes students need to be given the option to practice a piece over and over again until students master an idea before they move on to a more advanced one to avoid creating gaps in knowledge.
