Illiteracy used to mean not being able to read and write. No longer. As Alvin Toffler says above, it means much more. Its definition has broadened while also becoming much less specific.
Over 30 years ago, my father-in-law decided to retire. He had worked for more than 30 years as a draftsman and loved his work. He enjoyed the precision and creativity that his job allowed. Throughout his time as a draftsman, he moved from pencil and paper to learning to do his drawings using a computer program. As T-squares, pencils and papers were moved further and further away from his work life, his desire to retire became stronger and stronger. He finally made the decision to retire and never looked back. When asked how he knew it was time to retire, he said quite clearly, “I didn’t want to learn another way to do my job. I loved my work, but I didn’t want to learn anything new.” In other words, he didn’t want to unlearn and relearn. For him the timing lined up. He was old enough to retire and had a good life ahead of him with lots to look forward to. For others, things don’t line up quite as nicely.
In education – as in most other fields – learning, unlearning and relearning are constant states of being. Many times the barrier is one of mindset rather than difficulty with the skill or concept. It’s one thing to decide at retirement age that you’ve learned enough and it’s time to move on; that’s not so easy for most of your work and school life. How literate are you? What have you unlearned and learning recently?

This time of year brings with it a lot of professional development opportunities for educators. Last week, several teachers were able to attend a conference on technology integration. It is a conference held each year to share ideas and experiences with technology in the classroom. This conference is what all professional development should be…inspiring. 
I have had the great pleasure of working with a small group of students during the past few weeks. Our focus is on math, specifically fractions. I haven’t been in the classroom full time for a few years and, although I knew that children pretty much remain the same, I wondered how I would adjust to the “new ways of doing business.” I found some constants and some things that made my “work” a bit simpler.
