In order to give students permission to rate, we have to go into the permissions section. Could there not be a checklist on the glossary form?
Well, the Forums settings also use the permissions section in the same manner, so this is not proper to the Glossary module.
In permissions, there is a plus icon for allow and there is a plus icon for prohibit. That is strange.
Nothing strange here. Take a closer look at the Column headings:
So if you click on the + icon in the Roles with permission column this will enable you to add a role with Permission (=Allow=; but if you click on the + icon in the Prohibited colum, this will enable you to add a "prohibited" role. Everything is very well explained on the next screen after clicking those + icons I should think.
When I switch role to student, they can delete and edit an entry that I, as administrator, created. Bad.
They can add comments. Good.
But they cannot give a rating. Bad.
Although the "switch role to... (student)" is a very useful feature for testing how things will look like to a student in a Moodle course, what you see and the actions you can perform are never guaranteed to be identical to what a real student will see or be able to do when logged in. This is the case of the particular scenario you mention. When testing things on a Moodle site, my advice is always to log in with a "real" student role.
Hope that helps,
