Formative is set up a little like Kahoot, where the teacher creates a panel of questions (or even just one question) and sends the kids a link to a question, survey, short answer response, etc. It saves all of the questions within the site so you can reuse them year after year. The site also establishes a data summary so you can check and see understanding.
One of the components I appreciated was the capability of making classes within the site. I feel that is an awesome aspect of the site. It can help aggregate data even better by comparing classes to each other, gauging needs of different levels. I can help a teacher do differentiation.
I decided to try the site out with my yearbook staff. I added a photo of a student at the fair and ask the students to caption the photo. They received 5 points for doing so. I think I am going to start doing this for a daily starter. There are hundreds of yearbook photos out there. If they caption them together, we can get several done with good captions!
