In these days every, a person knows that the present world is ever more interconnected and interdependent in many aspects for many things. We all share opportunities for global collaboration in such areas as scientific and artistic creation, trade, and international cooperation. These challenges and opportunities define the contours of our lives, even in their most local magnitude. Yet in spite of growing awareness of the importance of developing global skills, few students around the world have the opportunity today to become globally competent. But, it is the responsibility of the teacher to prepare the students for life in the real world in their communities and societies, both in the present—while students are in school—and in the college- and in the future—after they leave school/college behind. As today we are living in a global society, the knowledge and skills should people need to understand today's flat world and to integrate across disciplines so that we can comprehend global events and create possibilities to address them in our real life.
