Khan Academy's geometry section has been a fantastic resource for me because of the interactivity of the 'quiz' sections. I feel like the quiz sections are almost more valuable than the videos; the videos are nice because they offer a clear verbal walkthrough of problems, but the interactive quiz sections let students experiment with figures to see if constructing counterexamples (per say) is even physically possible with the given conditions. I feel like nothing is quite as instructive as a hands-on session of trial and error.
As well, students can sign up for an account through the website and earn points through a cute little game system and earn rewards. In addition to the points and badges that accounts keep track of for students, student accounts can also be linked to a teacher account. The teacher/coach account that is associated with it can view statistics for each student, including frequency of use and success rates.
One drawback to Khan Academy is that it requires student access to one-to-one technology to use successfully (in my opinion). Even if you don't have one-to-one access, you might be able to make a couple of computers with a Khan Academy activity set up one center in a set of stations that the whole class participates in.
Lauren,
ReplyDeleteI'm glad that you shared this resource because I've heard of the name, but I never really looked at what the Khan Academy was about in general. It sounds like you really enjoy this site and have had personal use with it. I completely agree with you that I like the video part of this site because I think students will like the simplistic view of the steps, but I think the quizzes are more insightful and helpful for students to see and solve. I like how in the geometry section, you point out that students have a trial and error to really see if they can construct counterexamples! I am sad to read that you feel as if this resource would need to be at a one-to-one school. What if teachers could use the computer lab at the school? Would it be okay if this site is visited infrequently? I like your idea of stations and trying to make this accessible for students and teachers. This could be a great review game activity as well!
Great find, Lauren!
