E-BOOK OF A DIFFERENT COVER: Expect to see many trials of digital curriculum popping up. Here's an intriguing one that's been going on in a corner of LAUSD: 230 students and four teachers in New Open World (NOW) Academy in Los Angeles have been trying out Copia, an e-reader that emphasizes creating collaborative learning environments where students can share questions, notes and so on. (Other features include dictionaries, study aids, a "speak" option that can read highlighted text outloud and messaging). Copia works on iOS, Android and Windows platforms. The pilot was run by the blended learning design firm, The Alvo Institute, which plans to release the full results of the effort in late June.
