And perhaps it would be best if we simply taught the students the meaning of the word "theory", which would probably help you out as well, given that your grasp of the definition of the term seems a bit shaky.
By definition, a theory is "unproven", it is "a plausible or scientifically acceptable general principle or body of principles offered to explain natural phenomena <a theory of organic evolution." Note that the definition of the word theory nowhere contains the word "fact".
