Communication Resources for the Modern Leaner

When I review a new EdTech tool or resource I want to know how it can support and build essentials skills before I think about content. I always start with how a tool can support one or more of the 4Cs of collaboration, communication, critical thinking, and creativity. 
There are many incredible tools to support communication. ISTE has a set of standards to connected to essential communication skills for students. 

Communication - Students use digital media and environments to communicate and work collaboratively, including at a distance, to support individual learning and contribute to the learning of others. Students will:

• Interact, collaborate, and publish with peers, experts, or others employing a variety of digital environments and media.
• Communicate information and ideas effectively to multiple audiences using a variety of media and formats.
• Develop cultural understanding and global awareness by engaging with learners of other cultures.
• Contribute to project teams to produce original works or solve problems.
