Collaboration is a major feature of global projects. It's also an important part of 21st century learning skills. It's embedded in the new BC curriculum. You can also see elements of this throughout various inquiry models....and as if these weren't enough, it connects with the later stages of SAMR. Simply put.....it's beneficial for students and teachers to incorporate global projects into your lessons.
It allows participants to learn about new people and cultures. It allows them to make connections with people they never would have met and to learn with them.
Some of the project topics that I stumbled across were: global encounters, water, my city and me, and the world we live in.I was very impressed with this, I will use it, and I'd encourage you to check out the websites.
