Through formative assessment, teachers check student understanding, get valuable data on student learning, and then use that data to modify instruction. When teachers know what students know (or don't know), they can adjust to meet students right at their level. There are digital formative assessment apps for everything from discussion to quizzing, polling, and student responses to interactive lessons and videos. Secondary teachers will be able to generate a clearer understanding of using digital formative assessment tools in their classroom while keeping their students engaged and learning. Digital tools to promote student discourse and collaboration such as Quizlet, Kahoot, Padlet, and many more are demonstrated to make your learning environment a fun, yet enriched one.
