When you know what you want your students to achieve, that is the time to hunt for e-Tools that will enhance the learning. There are lots of great sites to help you with this.
Check out this Google Doc pictured below that I began with a school to compile a list of eTools against specific learning intentions at each level of the school. Enjoy but also please add to the possibilities as this is an editable document. http://tinyurl.com/etools4lit
You can locate your own eTools by using a search engine and keywords for what you want.
For example, Natural Readers software was found by doing a Google search for "free text read software" and Popplet Lite by searching the iTunes Store via my iPad for "free mindmapping app". So, if for example you wanted to find a good tool to stop students copying out quantities of text when they research, you might search via Google and the iTunes store for "free notetaking software apps". If any search fails to find anything, try removing the word "free".
