If it is dimension side , use show values with no data in Visual
If it is on fact side add +0 to formula
in edit query mode, reverse the steps.
So strictly speaking the data model does not have a LEFT/RIGHT join concept.
But I'm assuming that what you actually want is to show all students regardless of whether they have an attendance record or not. Typically the visuals in Power BI will hide rows that return a blank value so the "trick" is to create a measure that returns a non-blank value. So if you wanted a count of attendance you could do something like the following:
COUNTROWS( Attendance ) + 0
