I have worked with some teachers that have wanted a way to give a daily assignment to their students and collect each student's daily response in one Google doc for each student. Here are the instructions to easily set this up.
At the bottom of this page you can fill out the form and see how it works. Fill out the form, then in the embedded folder with the student's files, open the file of the student for whom you added the form, and see how it is appended.
1. Create a project folder with a subfolder to hold the assignments.
2, Create the Form
3. Create the Assignment Document in the Assignment Folder and format it.
4. After you have the Assignment Document formatted just the way you like, make copies of it and name each copy with a student's name. Your Assignment folder should have a doc for each student.
There was a Recent Google Plus Discussion in which the teacher wanted to create a 'Discussion Board' in Google Classroom. The eventual answer was that it is possible to use the Question Feature of Classroom and allow students to respond to each other and have a stream that the teacher could use to grade the student discussion.
But in the meantime I decided to see if it was possible to create something within a google form that would allow the students to see and take part of the discussion and give the teacher a document of said discussion. So using Doc Appender, I have been able to create a project that might be useful for some to use.
To use this successfully as a discussion board, you will need to open two windows side by side. In the first window open the form, and in the second window open the Discussion Responses Spreadsheet, and all three documents so you can track in real time what is happening as you submit the form.
