Ideas for using Pixton in a paperless classroom...

I am a big fan of portfolios, or any other techniques that helps students see how they are learning and developing over a long period of time.

Pixton can be a fun tool to illustrate this as part of a students online portfolio, facebook page, igoogle home, student blog, or whichever paperlesshome base students choose to catalog their learning.

students could make a comic a week (or over whatever time period works for you) that shows what they learned that week--not necessarily a list of facts, but ideally a comic about what the student learned about them self as a learner.
When students are metacognitive about their learning and articulate that, be it in writing, comic, or on a chart or graph (making goals and timing them, or any method of quantification you could imagine) they establish problem solving strategies that can help make their thinking more flexible.
