Marking and feedback
Description: Kaizena is an online Google Docs’ extension for providing feedback on student work. Educators can use Kaizena to leave voice comments, text comments, and annotations directly on students' Google Docs. Students can then listen to the feedback and make revisions based on the comments received. Kaizena offers both free and premium plans. Users are required to sign up for a Kaizena account to use the platform. Teachers and students can sign up for accounts using their Google credentials or by creating a separate Kaizena account.
Evaluation: Kaizena is a valuable tool for providing feedback and corrections for learners. It helps educators reduce the time needed to evaluate students’ work by embedding comments as voice and text messages or explanatory videos. It also allows educators to save and reuse not only comments but also whole lessons, thus avoiding repeating themselves. The tool also provides many lessons for common mistakes that educators can include in student feedback. The free version can only be used as an extension to Google Docs, while the premium version can also be used on Google Slides. Average IT skills required.
