Groups - prevent a non-editing teacher from seeing other groups in course

Symptoms: A non-editing teacher can see student information (eg assignments) from other groups in the course - and this is not ok due to privacy issues.

Resolution

When you have groups organised, the non-editing teacher needs to select their own group from the drop down box at the top of the screen. This saves the teacher having to find their own students among others.

If privacy is an issue, then try setting the capability moodle/site:accessallgroups for non-editing teachers to prevent.
