How I Use It
In the past, I would link the relevant Khan video in my website and ask the students to use it to refresh their exposure to the day's material. Toady, I no longer use the website. I still refer kids to Khan for basic Algebra help, but not at all for classes that require any kind of attention to detail.
The concepts in Statistics are sometimes very heavy lifts for high school students, and explaining the concepts is difficult for even a professional educator. Khan's ability to put out TONS of content that seems to cover seemingly every concept is really sad wishful thinking. My students laugh at how briefly he covers concepts that require far greater care and detail to learn.
