These boards are still being added to, but they are a good starting place. Personally, I had used Wallwisher in the past, but wasn't a huge fan. I started using another tool, Lino, which was like Wallwisher. Both are electronic bulletin boards centered around a specific question or topic. Then you open the board so others can contribute resources to the topic or answer the posted question. Either tool would be great for exit questions, brainstorming for a project or paper or collecting online resources centered around a topic. I could see using this as part of a web evaluation activity. The students have to find a reliable website related to a specific topic everyone is researching. They could give the link and explain how they know it is a reliable site. Here is a sample Lino canvas I used this summer during one of our training sessions:
After working with the new Wallwisher, I'm going to give it another try. Although Wallwisher doesn't have an app for the iPad, I can still go to the internet on the iPad and use Wallwisher to create new boards or respond to boards. Tom Barrett has a slideshow showing several interesting ways to use Wallwisher in the classroom. On his blog, Sean Banville provides 105 ideas for using Wallwisher in the classroom.
