Adobe Spark (formerly Adobe Voice) is an awesome multi-platform application (Chromebooks, IPads, PC, MAC) that lets students demonstrate their understanding of concepts through the use of photos, icons, video, text and voice recordings. The output is a movie file that is easily viewed in the classroom or embedded on websites. Multiple templates that include background music and color palettes enable students to create professional presentations in one or two class sessions. This tool is successfully used from kindergarten on upward. This twelve-minute video explains everything you need to start using Spark in your classroom.
