STEM teachers are educators who teach science, technology, engineering, or mathematics. Most STEM teachers specialize in one subject area, such as algebra or chemistry, especially at the secondary and post-secondary levels. However, primary school educators often teach general STEM lessons. Teaching students about science, math, or technology and motivating them to get excited about STEM subjects are your primary responsibilities. Your job duties include curriculum design, lesson implementation, student evaluation, and collaboration with other teachers. You must participate in professional development and continuing education to make sure you remain current in your STEM subject area, as the field is continually evolving.
