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 1500 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.

Slack & the SAMR Model

Dr. Ruben Puentedura’s SAMR model offers a lens for examining how technology is adopted in a classroom. As you strive to incorporate online tools into your classroom, we encourage you to use this model as an analytic tool.

  • Substitution: Instructors and students use Slack as a text messaging tool rather than having an in-class discussion.
  • Augmentation: Instructors and students can ask questions, respond to comments, and communicate outside of class time using Slack.
  • Modification: Students use Slack channels to manage group projects in a single workspace (e.g., sharing files, providing feedback, engaging in live video chats, sending text messages).
  • Redefinition: Students can integrate more than 1,500 apps (e.g., Google Apps) into their Slack channels for improved efficiency in project management and communication.
