As an online and traditional classroom instructor, I incorporate news and announcements weekly. For my online class, I post news on the main page of the class forum. My traditional class sees the news and announcements on the whiteboard screen when they walk into the classroom. It is also available for them in Dropbox and Blackboard. The content includes important dates, trends in the industry and career news.

Graphic such as the above can be created in a variety of drag and drop web-based software or templates, or more robust software such as Adobe Illustrator or Photoshop. This example was made using Canva-an easy and straight-forward tool with libraries and sized templates for multi-use.
