Google Sheets data to MIT App Inventor

I am posting this on behalf of one of my students.

I am making an app to get homework for kids, using google sheets that I do not own. At the moment I am manually updating the app weekly, I would like to make it so that the app will update itself weekly. Ideally, I would like the app to update every time a teacher puts in a homework assignment, but I am an amateur coder and do not have much experience. I have tried many different tactics such as using google forms, but none seem to work.

If anybody could help it would be greatly appreciated.
Thank you,

Here is my code:
