Can you expand on this? I looked at the blog post and as far as I can tell piCards operate the same way as plickers. In my use of Plickers, I can either choose to give each student a specific card for personalized polling, but I can also just not identify the student with each card which allows for anonymous polling.

What have I missed here?

In plickers, you still get to see responses on the cards and since you know the students in most cases, you can identify and if you want to single out a student (which I'm sure most teachers don't do), you can do it. "piCards: Anonymous Polling App" is a truly anonymous feedback system where you cannot know the students' response unless you read their cards. This will also give more confidence to students to freely answer without worrying about getting it right.

Thanks for the awesome question :) you can get in touch with me over email as well - [email protected] Would love to listen to any feedback you or your fellow teachers might have. Thanks again!
