Sketchlot is a free collaborative whiteboard service that works on any device that has a web browser. I tested it on my MacBook, my iPad, and my Android tablet this afternoon. Sketchlot is designed for teacher and student use. Teachers create their own accounts and then inside that account they can create a list of students. Each student is assigned his or her own password to use to join a drawing shared by his or her teacher. Teachers can create as many drawings as they like and share them on an individual basis. Teachers can share their drawings to one or all of their students at a time. Students can create their own sketches to share back to their teachers through Sketchlot.
Applications for Education
There are few ways that teachers might use Sketchlot with students. Teachers could ask students to create and label diagrams and share them via Sketchlot. Students could use Sketchlot as a collaborative mind mapping tool.
