My current favorite is Audioboo, a great app students can use record and share reflections. They can comment on other students' reflections. One strategy (called AudioMo) asks students to record a boo everyday for a month, reflecting on what they are learning. At the end of the month students can record a metaboo where they summarize their learning. Boos are limited to five minutes in length. You can even find Audioboos in iTunes.
