Symphonical is an online tool that allows students to collaborate on projects and keep track of individual tasks. Organized in an easy to use grid containing categories for Not Started, In Progress and Completed, students create notes containing tasks to move around the board, thus showing visual progress. Any task that contains a due date can then be viewed on a calendar as well.
This application does require an account, but the basic service is free. Once one account holder logs in, other team members can be invited from within the app to collaborate.
An additional feature that facilitates collaboration is the ability to invite team members to a Google Hangout from within the app so that students can discuss tasks (which can be imported from Gmail and Google Drive) and priorities.
This simple and free platform can help students get organized, prioritize tasks to achieve success for the project and best of all...collaborate!
