I've long been a huge fan of Google forms for exit slips, surveys, and formative assessments. For me, it is one of the easiest tools to efficiently engage my students in reflective learning and assessments. I've even dabbled with using Google forms as a HyperDoc.
Another great feature of Google Forms is the ability direct learners to different sections of the form based on the answer chosen in a multiple choice question. This is a great way to support differentiated learning experiences. Students can be directed to a statement, video, website or other digital resource based on the answer they choose.
