One of the changes I wanted to make with my classroom this year was to make sure that they were sharing their learning with others. When you give students an opportunity to share their work outside the classroom walls, they typically will produce better work.
Padlet was one tool that I wanted to use more with my students. We use them a lot for literacy tasks. Students are writing book reviews, sharing current events, as well as keep track of their reading logs.
Students have the ability to type in their response or record videos. If you want to have extra long videos, I would recommend their Backpack package, which is $5/month or $45/year.
