Globe and Mail visual graph: Is technology a boon or burden in the classroom? As the world becomes increasingly digital, school boards are trying to negotiate technology's role in the classroom. Some have embraced digital tools, enhancing their classrooms with Smartboards, cell phones and social media. Others have favoured tradition, claiming technology is a distraction and a nuisance. Where do Globe readers stand? Each dot on this graph represents one person's response colour-coded by age group.

Why I Like Prezi In my life, I have given a *lot* of presentations. In high school, they were presentations on group projects. In university, they were presentations on research projects. At Google, they're presentations on how to use our APIs. When I first started giving presentations, I used Powerpoint, like everyone else. But I kept thinking there must be a better way, and I experimented with other options - flash interfaces, interactive Javascript apps. Then I discovered Prezi, and it has become my presentation tool of choice. Prezi is an online tool for creating presentations - but it's not just a Powerpoint clone, like the Zoho or Google offering. When you first create a Prezi, you're greeted with a blank canvas and a small toolbox. You can write text, insert images, and draw arrows. You can draw frames (visible or hidden) around bits of content, and then you can define a path from one frame to the next frame. That path is your presentation. It's like being able to draw your thoughts on a whiteboard, and then instructing a camera where to go and what to zoom into. It's a simple idea, but I love it. Here's why: It forces me to "shape" my presentation. A slide deck is always linear in form, with no obvious structure of ideas inside of it. Each of my Prezis has a structure, and each structure is different. The structure is visual, but it supports a conceptual structure. One structure might be 3 main ideas, with rows of ideas for each one. Another might be 1 main idea, with a circular branching of subideas. Having a structure helps me to have more of a point to my presentations, and to realize the core ideas of them. It makes it easy to go from brainstorming stage to presentation stage, all in the same tool. I can write a bunch of thoughts, insert some images, and easily move them around, cluster them, re-order them, etc. I can figure out the structure of my presentation by looking at what I have laid out, and seeing how they fit together.

"In a recent post, Edudemic introduced us to a very intricate, color-coded visualization by Envisioning Tech on what to expect in education technology in the next 30 years or so. And these concepts are not broad generalizations- Envisioning Tech takes topics like digitized classrooms and tangible computing and segments them into practical ideas to produce a well-organized, cohesive diagram"
