Je suis en classe  - I'm in class

Je suis dans la classe - I'm in the classroom

... I actually don't see the difference between  'classe'  in both sentences
in my understanding both sentences could mean I'm in class or I'm in the classroom

In a situation where we are deciding whether to use le français or simply français with the verb parler, would one or the other be more appropriate in certain settings, or are they both equally valid? I am curious if there are any nuanced differences between the two.
