How do I make sure each student only has one login
If your students already have multiple Yacapaca accounts
Don't panic. You can direct the students themselves to sort this out. On each student's to do list a button links to a popup where multiple IDs can be merged.
This leads to a very simple popup where a second login and ID can be added. Even if the student has acquired several different IDs from different teachers, they can all be merged together using this simple system.
If doing this with a whole class, remember to print out ID Cards for both of the student sets of which they are members. It is unlikely that students will have kept a record of both logins.
If you want to put students into an additional student set
Whether with a different teacher or not, you can do this from their current Student Set page. This screencast will show you how.
