We can now use Google Forms to make quizzes in Google. These quizzes have a number of useful features; they are self checking, so you won't need to spend time marking them. They can included pictures and vidoes. They can track all your students answers and at a click of a button you can see a list of the answers your students have given. And you can add feedback to your quizzes, so students can be given feedback on their results. This tool has its limits, but it's really useful for formative assessment and checks. This is not only a useful technology for teachers but it is also a useful technology for your students to learn to use. Get them to make their own formative assessments too, for them to try out on other students.
