Does any one know how can I disable teacher's ability to unlock grade items?
Our school locks the students' grades once a month by locking the grade items in a moodle course, but the teacher in the course can still unlock it. I use the site administrator's account to redefine the teacher's role, and I set "lock grades or items" to allow, and "unlock grades or items" to prohibit (I tried set it to "prevent", still not working) , but the teachers can still unlock the grade items when it is locked.
Does anyone know how to solve it?
Thanks so much
