As our daily lives become more integrated with science & technology, our education systems need to ensure that all students are gaining the essential scientific literacy and critical-thinking skills to navigate the diverse technological landscape that defines the 21st century. Although STEM education has been at the forefront of global initiatives to prepare students to life, recent systemic reviews show that current pedagogic methods focus separately on individual subjects and fail to impart the necessary integrated systems thinking for students to design solutions for complex contemporary problems ailing our world. Game design processes employed as pedagogic tools can be the answer to contemporary issues in STEM education. As a unique blend of artistic and engineering processes, game design is an iterative design process that requires research, synthesis, dialogue, collaboration, interdisciplinary integration, and systems thinking to implement solutions for the construction of a desired experience. These affordances fit the bill for a design-based, student-centered, constructionist, hands-on learning experience that is desired by educators on both the national and international levels. Thus, game design could be the pedagogic tool necessary for STEM education to adapt to the needs of the 21st century and the future.
