I am a student working on the AP Calculus AB portion of Khan Academy and find it to be very helpful. The videos and practice problems really make sure that one knows the material to a high degree.
I just wanted to put forth a idea to make something that is good even better. This idea is to install a comments section right below any practice problem in Khan Academy.
- By posting a comment section, anyone with further questions about the material will be able to address it to the community. This will help aid them further than the explanation that is already provided.
- It will allow community members to clarify the explanation that has been already provided.
- The comments under the problems will never disappear, so kids in the future with the same questions can easily get them answered.
This will be similar in function and use to comments under a Khan Academy video.
