The Web 2.0 tool that have used and will start to use again is Quizlet. I used it with my 7th grade Geography class 2 years ago as a study tool for vocabulary words learned in class. They loved it! Before the unit, I would upload all of the vocabulary. As students finished assignments, I would allow them to log onto Quizlet to review. There are multiple things they can do on the site. They can learn the set of terms posted by the teacher, test themselves, and play games. There is also a feature where they can interact and chat with one another. Any user of Quizlet can use other sets posted by users, so you do not always need to create new ones. I would like to use this with my high schoolers and place it on my website for my Action Research project.
