Estoy en casa would mean I am a home, that is not used much in Colombian Spanish, rather estoy en mi casa.
Estoy en la casa refers to being in a specific house known to both parties.
Estoy en la clase - here clase pertains to the class room, the people of the class, everything that makes up the class
Estoy en clase refers to being in the process of being taught
Estoy en casa. - I am at home.
Estoy en clase. - I am in class.
The 'la' is simply not needed in this case... Just as in English, you do not need 'the' here.
