So far, I've created 4 maps that are great places for me to start organizing my thinking and the resources relevant to my preservice teacher prep. I've created maps depicting my PLN, my teaching philosophy, my online and social media learning tools, and I've started a map for adolescent literature. This last one is something I've always wanted to create so that when students approach me asking for another related good book to read (by genre, author, topic, theme, etc.), I'll be ready to give them valid suggestions.
I really like the MindMeister application so far... it's a great way to organize thoughts, ideas, resources, and whatever else you need to organize. Go give it a look. I hope you find value in it like I do!
