A. The nature of the case explores how using Khan Academy can be especially effective with students that failed algebra in the past.
B. Using the "hint" function and having opportunities to ask peers and then engage with the teacher allows for multiple ways for students to interact with and learn new mathematical concepts. The teacher's role is as facilitator. The "coach" function of Khan Academy allows the teacher to see "who got it" and "who doesn't." Historically students taking algebra for the second time have difficulty with engagement and the teacher is overwhelmed trying to get around to all students. The use of the computer, opportunities to work and learn from peers, the ability for students that are ready to keep moving forward, and the design of the Khan Academy looks like a highly motivating way to stay engaged and learn algebra!
C. I have used Khan Academy 1 on 1 with students at the elementary school level. I appreciated seeing it used in a whole group high school setting.
D.This lesson can be used in the classroom right away! I was a person who had to take geometry 3 times. I would have loved the opportunity to use Khan Academy as a kid.
I rate this film experience a 5 out of 5!
