I have been reminded of several platforms for getting online students to collaborate online. I would welcome feedback on your experiences and how they work. Why don’t you go to my Padlet page and add your own ideas and comments

Hi John, I’m afraid I was not allowed onto your Padlet page…something about Cookies,
Anna, I am coming to the conclusion that there is an issue with Padlet and WordPress. I have put a link to the Padlet page on Open Studio. The issue of people being able to access your creations is quite an important one. If students have the experience you have had they soon get discouraged.
Indeed. I’ll try on Studio and let you know.
