Padlet is essentially an online bulletin board that makes it easy for instructors and students to share content. You can take a look at Padlet at padlet.com.
Below are two tutorials developed by the HCTM program at Bellevue College. Part 1 showcases some of Padlets abilities and Part 2 gives a demonstration for creating a Padlet page and embedding it to your Canvas course. Enjoy!
