Created a Kahoot for my library orientation. I worry that the message is lost in the fun of playing the game. Students certainly enjoyed themselves however. It's super fast to make one.
One of the problems with vocabulary walls is that often the kids who need them most are sitting near the back of the room and can't see them. Imagine instead a piece of paper, created by them with the word and then a QR code that links to a video of them explaining the word, or a definition written in their own language or something meaningful to them. I know we're trying to get away from paper and pencil but this would personalize the word walls, would be MUCH faster and use more media than just definitions written in ink on a page. Might try to experiment with both kinds to see which one makes a difference.
The student could create something as simple as this using https://www.the-qrcode-generator.com/
and could then use their device whenever they wanted it. Creating the personal word wall could be one of their in class assignments. Or they could contribute to a classroom Padlet math glossary.
I've started to rediscover sites that I used to use a lot. Answer Garden is one of those. It is described as a digital place to scribble. You pose a question and then everyone can respond with their answers.
I've decided to post one for the first day of school so that kids can see that their worries are pretty much shared by lots of other people.
