When a Google Classroom is connected to an Edpuzzle classroom, the roster is automatically imported.
However, once a classroom has been connected to Google Classroom, the only way to add more students to the class is to add the students to the Google Classroom course and sync them to Edpuzzle.
Here's how you can sync your students Google Classroom roster to Edpuzzle:
1. Check your Google Classroom to make sure the student is on the roster for the same Google Classroom connect class in Edpuzzle. If they are not, you'll need to add them to the Google Classroom before proceeding
2. Go to edpuzzle.com and click the "My Classes" tab at the top right
3. Select the class you've connected to Google Classroom
4. Click the Students tab and on the right-hand side you'll see the "Sync students" button
And you're ready to go!
Any new students who joined the Google Classroom course after it was originally imported will be enrolled in the Edpuzzle classroom. The student will have to log in to Edpuzzle with their Google Classroom account and be on the Google Classroom roster as well.
