How I Use It
My students were struggling on some topic, and I was recommended Khan Academy as a way to supplement my teaching. My coteacher and I reviewed the video, thinking it would explain the concept in a different way students could understand. It turns out that several of my students, in no uncertain terms, were more confused about the concept, could barely see some of the pixilated video, and had a hard time understanding the speaker.
If the explanations were simpler, it could be a better and more useful teaching tool.
