I used Padlet to create a page about Collaborative Problem Solving (CPS). CPS is a 21st Century Skill and ATC21S is doing extensive research on CPS. I have embedded some text, articles, websites, and videos about CPS in the page.
Padlet is a Web and Mobile App that allows you to create beautiful web pages. Just by double-clicking on the wall, you can add pictures, text, or videos and arrange the items to form any collage pattern. For more info read this article. Here is a short video on how to use Padlet.
