STEAM fields are the areas of science, technology, engineering, the arts, and mathematics, or applied mathematics. Various other definitions for the "A" exist, but no other definition formally defines the arts with research. STEAM is designed to integrate STEM subjects with arts subjects into various relevant education disciplines. These programs aim to teach students innovation, to think critically and use engineering or technology in imaginative designs or creative approaches to real-world problems while building on students' mathematics and science base. STEAM programs add art to STEM curriculum by drawing on reasoning and design principles, and encouraging creative solutions.
