That brings me to Aviva Dunsinger. She's a risk taker of extraordinary strength. She's one teacher who models for others what it means to teach and move between physical and digital spaces. Aviva started this year with one word (uncomfortable) to shape her teaching craft. She blogs about her teaching (Living Avivaloca), tweets out what her students are doing each day (@avivaloca), and shares the story of their collaborative learning (Our Wonderful Wednesday). On a daily basis, Aviva shows what she knows about herself as a teacher and what her students are learning in her classroom. Her reflective practice is visibly done for larger audiences to see, with feedback that shapes her teaching and her student's learning. Her teaching practice moves fluidly from the physical place of the classroom to the digital space of social media (blog, twitter, storify, etc.).
