We know effective assessment can be more powerful than class size reduction for raising achievement. Take a deeper look at how technology tools (mostly free) can check for understanding. Projects previously requiring a semester can be accomplished in a period. Mobile phones, MovieMaker, iMovie, and a host of Web 2.0 sites can do the job. Even PowerPoint and Google can be tapped. iPads have surprise ways to support teaching and assessment. The digital age produced spectacular tools that match the learning style of students native to the touch screen, who create videos for the web, texts on a mobile, and stream media everywhere. These skills and tools, often free, should be adapted for assessment. Bring your laptops and cellphones for examples in an interactive session from a leader in the field.
