Screen capturing tool that allows you to add questions to comments and then share information. Great way to use for reading. Ask and answer questions to demonstrate understanding of a text, referring explicitly to the text as the basis for the answers.
Refer to details and examples in a text when explaining what the text says explicitly and when drawing inferences from the text.
Quote accurately from a text when explaining what the text says explicitly and when drawing inferences from the text.
Cite the textual evidence that most strongly supports an analysis of what the text says explicitly as well as inferences drawn from the text.
Why text is only one path directed. Please share the video in the blog, because it show how textbook do not carry students' interests in mind. Also may hopefully change the mind of some teachers to get out of the text and to look another places.
Looking for a different tool look at this map. I like the tool to show students cycles of things. The one that is linked in of web 2.0 apps setup by types. This link is one that I created using the program, http://www.mindmeister.com/18887812. You also can share it, export as PDF, and Embed in to your site.
