That I learned from online course: Kaizena

 Kaizena supports the performance of students. It takes place like that in the teaching process. It is a feedback tool for Google Docs. It is an add-on tool used in Google Drive. 

Teachers can give feedback on student work quickly, simultaneously, and personally by typing or recording their voices. They can review up to 75% faster than typing with voice comments. Even better, over thirty years of research shows that students love to hear the teachers' voices. 

Also, let them know you, as a teacher, care with a voice comment. Or personalize one of your lessons by adding a text comment to the same thread. Highlight and speak your voice comments, attach lessons, track skills and complete your rubric right inside Google Docs.

Besides, you can share their lessons and rubrics with your department, school, district, or campus. That provides everyone on the same page, and everything is in the same place. You can mix and match comments. It gives a chance for a two-way conversation. Thanks to Kaizena, students have access to the same commenting tools as teachers, and can reply to your comments with a voice comment of their own! 

Install the Kaizena as an addition to Google Drive, open it with your email account then activate it which is found under the additions title on google docs. It is ready to use.
