Slack was designed to be a powerful communication tool to aid team collaboration. Its main use is to provide a platform for volumes of communication between a large team or classroom of individuals. Because communication on this scale can become unmanageable and inefficient this tool can be used to ensure that communications happen all in one place and can be segmented by creating Channels for various topics. Educators can assign users to as many (or as few) channels as they need in order to keep topics visible to the class members who want to see any individual topic.
Slack communications is a simple and dynamic tool to use. Slack offers such as integration with services students and teachers use every day such as drop box, it allows for the fast and easy searching of posts from users at any time through specific filtering, it allows for private or one to one group communication regarding sensitive subjects that are specific for one user and finally it is accessible on the go via the app. Slack offers a free version for small groups as well as two different premium versions.
