If we want students to excel at STEM, we really need to have them study Latin. The classical languages are the true languages of STEM: its philosophy was composed in Latin, its nomenclature comes from and still will come from Latin and Greek. Latin uses and exercises the same parts of the brain as math and will teach students how to communicate, especially in written form, more effectively than studying English alone.
In the U.S., we do not teach foreign languauges to the degrees of fluency that other countries do because we don’t have to; English is the lingua franca of our age.
Nobody is going to get a job from such basic language skills as being able to say their name, describe their bedrooms, and order a cheeseburger.
Business meetings across the globe take place in English. Latin supports STEM as well as English.
