Wow! I now have another amazing FREE online tool to introduce to my students! http://www.hypothes.is.com This tool enables the user to highlight text, annotate it and share it! Not only will it come in handy during my own personal educational journey (going back to school after many years!), I can share this with my students and use it in my own classroom.
Awesome! And it’s not just free, it’s open source and doesn’t collect your data!
