Math & Science Tutoring on YouTube

This comes to us via a tip from Twit­ter. The Khan Acad­e­my has now post­ed on YouTube over 800 videos (find a com­plete list here) that will teach stu­dents the ins-and-outs of alge­bra, geom­e­try, trigonom­e­try, cal­cu­lus, sta­tis­tics, finance, physics, eco­nom­ics and more. The clips have been record­ed by Salman Khan, a Har­vard Busi­ness School and MIT grad. And to give you a feel for them, we’ve post­ed above the first in a long sequence of lec­tures on dif­fer­en­tial equa­tions. (The remain­ing lec­tures can be found here.) This YouTube chan­nel, which now appears on our list, Intel­li­gent YouTube Video Col­lec­tions, is one of sev­er­al video sites that pro­vide free online tutor­ing via video. As men­tioned in the past, you can find online good video col­lec­tions ded­i­cat­ed to chem­istry and cal­cu­lus.
