Stay Relevant

We are always discussing what teaching in the 21st century is all about. As digital immigrants it is quite tough for some of us to let go of some old (successful) practices in favor of new ones. Again, the painful situation of leaving our comfort zones.
The thing is, as Educators, we MUST be ready or at least willing to learn more about everything that might facilitate students' learning not to mention their survival in a world without walls. The attached video will show how important it is to be aware of these changes in the world we live and the way we communicate. Are we supposed to rush and get to know EVERYTHING about it? I would never say that. However, I strongly believe we should be open and receptive to it if we want to survive as well and still be heard. The video is another variation of Karl Fisch's, "Did you know?" video.
I would really appreciate to know about your opinion. Have you been using these social medias? How can you implement it and make a difference in your daily teaching?
