Wiki

 https://www.edutopia.org I liked the website, since it's well-made and the design is great. They have different interesting articles such as teaching strategies, online learning, social and emotional learning.

All of the articles are up-to-date and very informative. I've read the one called 

"6 Exercises to Get to Know Your Students Better—and Increase Their Engagement" and I enjoyed it a lot. 

A very helpful resource.
