How I Use It
I use dropbox with the "Notability" app. I have an iPad in my math classroom on which I create all the notes (think definitions, like a powerpoint, and pre-written problems). Then, throughout class I write all over the notes as we work problems, have discussions, etc. I have connected Notability with dropbox so that each lesson saves automatically by date, and then it autosyncs (with no work from me!!) to a dropbox folder with all the notes in it, one folder per period. Then, I have provided each period with a link to their folder! They have access to our notes every day! So great for when they are sick and absent, or for when they didn't want to copy down the whole table or graph we were working on. Its all there, by date, with no work from me! Plus, anything else I want to post (practice tests, practice test keys, etc) are easy to upload to dropbox with a single click, and are instantly available to them! I also like that the link is a more private way of sharing. Things like online textbook codes and such can be accessed only by them, rather than open to the public! Dropbox makes my life easy!
Dropbox makes it easy on you to share information, documents, links, etc with your students! The fact that dropbox is well know and widely used makes it accessible from most apps and it works fluidly with many apps to make your life easier!
