In order to correctly use the JoeZoo app, a teacher must first download JoeZoo as an extension on their Chrome browser. Due to JoeZoo being such a simple and easy tool to use, in order to utilize the app efficiently, all one needs to do is open the application in a google doc and grade/comment away! For example, the Monkey-Checker can be used on a student's assignment in order to check the spelling of an essay or paper that is grammar-sensitive. This tool is helpful to teachers because it saves them valuable time in which they could be working on other important lesson plans and assignments.
An example of what teachers could use this tool for is simply for the luxury of commenting and grading their students google assignments in order to provide the feedback necessary for their students to improve.
As a student I think that JoeZoo Express could be an interesting tool to use due to its variety of helpful tools, however, I believe that teachers could find a much better way of providing feedback on assignments elsewhere.
