Google Classroom seems to be a promising application that may be available in September 2014. Although gClassFolders, creates classroom shared folders, and Doctopus allows you to manage assignments and feedback, this workflow could be challenging and difficult for some teachers who are not comfortable with scripts.
Google Classroom seems to replace that workflow. It seems to mange students and assignments similar to Edmodo. This application can be a great tool for school districts who are currently using gClassFolders and other scripts to help manage assignments. It has the capability to replace the entire gClassFolder and Doctopus workflow in a user friendly interface.
See for yourself!
