This morning my freshmen students took a quiz that I created and distributed through Google Forms. The quiz was self-grading because I used the answer key option in Google Forms. The quiz was also a timed activity because I used assignment scheduling combined with Form Limiter. With that combination I was able to give my students exactly 35 minutes to complete the quiz. On the short answer questions, I used data validation to require that students write complete sentences. If you’d like to do a similar thing, watch the following two videos that demonstrate the process I used in making my quiz.
