Grading has never been ____.
Yesterday Google quietly announced a new Forms feature that allows you to grade by question and allows for streamlined short answer grading. Now you can create short answer/fill in the blank questions and grade them in Forms itself. You provide an answer key (currently case sensitive) and if the student puts that exact answer, Forms grades it automatically. All other answers can be graded quickly with clicks.
With this new update you can easily add short answer and fill in the blank questions to your Forms quizzes.
Feedback is best when it is ____.
The new forms update also allows for individual feedback for questions and even allows you to post a link and test in your feedback. For example you could link to a video or screencast re-teaching the skill. Alternately if the student showed mastery to a video that would challenge them to do more.
