Group 4 - Animations.

I chose to look at Text2Mindmap.  This reminds me of the visual thesaurus that I often use.  I recommend it to help children see the connection between synonyms.  The search word was display and if you click on any of the synonyms, its synonyms will appear and the web continues to expand.  Click on the photo below to see this product in use.  It allows a free trial. 

This is the simple mind map that I created from Text2Mindmap:

Some paper mind maps can get very messy.  If you run out of room and need to start again, the whole thing becomes a very laborious.  With this website, students are able to see the mind map almost instantaneously and make adjustments as they need to.  Concept maps are a great way for students to retain declarative knowledge (Marzano & Pickering, 1997).  I would use a digital mind map once students have annotated their paper mind map to the point where it is becoming difficult to read.

SAMR
Substitution	Students record mind map as they would on paper.
Augmentation	Students edit mind map as new information comes to light.  This is done in real time.
Modification	Students define the levels in the mind map by colour.
Redefinition	Students’ mind maps are layered to look for patterns and differences.  Mind maps are published to a public forum for discussion.
