This is an amazing Google Docs add-on which allows you to make audio and other comments and feedback on students’ work. It’s a wonderfully easy way to mark homework and assignments. Students can also reply to feedback with audio comments.
Whenever a student responds to or acts upon your feedback, you will receive a notification in your Kaizena dashboard. You will also receive an email (you can turn off the email option). Along with new notifications for you, students now receive notifications when you post new feedback for them.
Kaizena notifications are now integrated into the comments section of Google Documents and Google Presentations. When you leave feedback for students through Kaizena a link to that voice comment is added to the comments section of the document or presentation.
