STEM, STEAM, STREAM, iSTEM, ESTEM...SMET?
In 2001, the National Science Foundation (NSF) used the acronym SMET to refer to careers in or integrated knowledge from science, math, engineering, and technology. American biologist and assistant director of education and human resources at NSF, Judith Ramaley, rearranged SMET to form STEM.
Well, that explains STEM, but what about STEAM? For STEAM, the intrigue comes from the definition of the 'A'. For some, A means Ag others think it means Art, while others think it represents Aeronautics. (Who is to say it couldn’t be Architecture?)
But STEM/STEAM has less to do with the first letter of the subject and more to do with how the subject matter is taught.
