Very helpful for concept introduction, remediation and use in FLIP classroom setting!
My overall opinion of this product is very favorable. The different colors Sal uses in his teaching are helpful for visual learners and the way he explains/breaks down difficult concepts is usually excellent. A wonderful tool for introducing a concept or remediation - just wish the length was a little shorter.
How I Use It
I have used Khan Academy Chemistry 1 and Chemistry 2 with my high school students. It is very effective for students missing lectures, those who need a second chance at material introduction, and to leave as part of my lesson plan for a substitute when I know I will be out (as it is difficult sometimes to obtain chemistry certified substitutes). I also use a modified flipped classroom style of teaching and these videos can be used as part of students' homework assignments. The only negative I have is that they are lengthy for flipped classroom use and students consider them a bit dry.
