Science, technology, engineering, and math (STEM) education is much more than the mashing together of these subject areas. Students will utilize STEM principles to engage in project-based learning (PBL) through performance-based projects. The engineering design process gives students a good, solid model to follow, which can be applied throughout STEM areas as well as to social studies, art, and even gym class. STEM-based PBL naturally lends itself to the formation of 21st-century skills, which are crucial to students’ development in school and beyond. STEM learning engages students and equips them with critical thinking, problem solving, creative, and collaborative skills. Because of the authentic nature of STEM-based PBL experiences and the final products that students create, students also develop communication skills as well as self-direction. STEM and PBL create a perfect marriage in ensuring students are ready to be the leaders of tomorrow.
