What is STEM and why is it important?

STEM is the acronym for the educational disciplines of science, technology, engineering, and mathematics. The science in STEM concerns two of the three branches of science; natural sciences, (which includes biology, physics, and chemistry) with the formal sciences with mathematics along with logic and statistics. STEM is a curriculum based on the integration of all four of these subjects that offers a lot of hands-on and relevant learning experiences for students. The result is students studying based on real-world applications.

Why is it important? STEM is important because it is spread throughout every facet of our lives. Science is all around us, technology is always expanding, and engineering not only is the basic design of physical structures but it also involves the challenges of our planet and the world around us. Think about it, mathematics is in almost every occupation and a part of our daily lives. Exposure to STEM will help give students the opportunity to develop an interest in it and potentially pursue a job in this field. A curriculum that is STEM-based places students in real life situations to learn hands on. This helps make math and science not only a learning experience but also fun and practical!
