The simplest definition is what it stands for, which is science, technology, engineering, and mathematics. .... The ultimate goal of STEM education is to encourage students to take an interest in STEM subjects at an early age.
Integrated STEM "Integrated STEM education is an effort to combine the four disciplines of science, technology, engineering, and mathematics into one class, unit, or lesson that is based on connections among these disciplines and real-world problems. More specifically, STEM integration refers to students participating in engineering design as a means to develop relevant technologies that require meaningful learning through integration and application of mathematics and/or science."
STEAM is an educational approach to learning that uses Science, Technology, Engineering, the Arts and Mathematics as access points for guiding student inquiry, dialogue, and critical thinking. The end results are students who take thughtful risks, engage in experiential learning, persist in problem-solving.
"...the two people who probably personify STEAM are the Renaissance figures Leonardo da Vinci and Michelangelo Buonarroti. Allthough these fierce competitors were known more as painters and sculptors, they were also renowned as inventors, engineers, and scientists. For example, da Vinci conceptualized the helicopter and battle tank and made important discoveries in anatomy, hydrodynamics, and optics. Michelangelo also worked as an architect and engineer, designing the large dome of St. Peter's Basilica in Rome. These men saw no boundaries between the arts and sciences."
