We know that our world is saturated with rapidly improving technology, yet we still face disparities that demand our attention. The issues facing our world today are not simple fixes. Food waste, chronic homelessness, the refugee crisis, and the mental health stigma will not be solved by one engineer, or one writer, or one politician. Being awesome at multivariable calculus simply isn’t enough. Georgia Tech’s motto is “Progress and Service.” Here at Grand Challenges we recognize that to most effectively create the progress our world needs, service is not an extracurricular activity, but a leadership style. In the classroom, students begin their yearlong journey towards optimizing teamwork to tackle the world’s Grand Challenges through the W-Model - a broadening and specifying technique that they learn to depend on. With the larger goal of exploring and learning together, students learn how to work with people who are different from themselves, and they begin to develop the skills of highly effective teams. Specifically, they learn that effective teamwork results from three things: honest communication, an understanding of each team member's strengths and weaknesses, and frequent team evaluation. The second semester course creates the space for teams to develop a solution to the problems they chose to address. Grand Challenges teaches students the problem solving, analytical, and critical thinking skills to discover real world solutions and allows them to put in practice what they learn in the classroom by funding the implementation of their solution.
