"Team communication
for the 21st century.
Channels
Organize your team conversations in open channels. Make a channel for a project, a topic, a team, or anything-everyone has a transparent view of all that's going on. For sensitive information, create private channels and invite a few team members
Direct Messages
Send messages directly to another person or to a small group of people for more focused conversations.
Calls
Take a conversation from typing to face-to-face by starting a voice or video call in any Channel or Direct Message. Make one-on-one or group calls right from Slack without needing to open another app or share invite links."
"Screencasting is the capture all of the action on a computer screen while you are narrating. Screencasts can be made with many tools and are often used to create a tutorial or showcase student content mastery. This page provides links to information, ideas, rubrics, and tools for the creation of screencasts by both teachers and students.
