Slack is a communication and task management tool. Users can create specialized messaging groups, or “channels,” according to different projects, teams, and organizations. What makes it different from other communication tools is that it is specifically created for work and collaboration. Files that are up to 1GB can be sent and searched within a channel, which makes file management easy. Slack also allows users to integrate over 1,500 apps and services into the chat, so that they can work without having to switch tabs and accounts. Functions like video chatting and screen sharing make it ideal for teamwork. Bringing Slack into the classroom can increase communication and collaboration, facilitate project management, and allow students to learn how to use a tool that is popular in many workplaces today.
