The authors of the articles are all widely known and respected for their work in the areas in which they wrote. They were asked to select a general issue that they consider important to 21st century education and to discuss the elements of it that they consider especially significant to educators. Some authors focus on simply exploring the issue itself and others also suggest educational applications.
