T&L Advisor Guest post — Henry Thiele, Chief Technology Officer for District 207 in Park Ridge, IL: Over the past few months, I have been sitting in on some focus groups comprised of teachers who have worked in a 1:1 setting for more than a year. A constant theme has been rising out of these conversations: differentiation works in a 1:1 environment. This goes against the reasoning of a recent EdWeek article that claims that a “mixture of students with varying abilities in one classroom causes even the most experienced and conscientious teachers to flinch, as they know the task of reaching each child is an impossible one.” I hate to think that we would give up on kids so easily. I believe today’s tools make understanding and providing support for each student possible. Our teachers use tools like Google Forms, PearDeck, Socrative, and EduCanon for quick formative assessments that show where their students' skills are so they can adjust lessons as needed. The combination of the device and assessment tools provides the pathway to differentiation that allows our teachers to reach every one of their students, no matter how big the challenge.
