21st century skills?

From Andrew J. Rotherham and Daniel Willingham:

"A growing number of business leaders, politicians, and educators are united around the idea that students need "21st century skills" to be successful today. It's exciting to believe that we live in times that are so revolutionary that they demand new and different abilities. But in fact, the skills students need in the 21st century are not new.Critical thinking and problem solving, for example, have been components of human progress throughout history, from the development of early tools, to agricultural advancements, to the invention of vaccines, to land and sea exploration. Such skills as information literacy and global awareness are not new, at least not among the elites in different societies. The need for mastery of different kinds of knowledge, ranging from facts to complex analysis? Not new either. In The Republic, Plato wrote about four distinct levels of intellect. Perhaps at the time, these were considered "3rd century BCE skills"?"

"People on all sides of this debate often speak of skills and knowledge as separate. They describe skills as akin to a function on a calculator: If your calculator can compute square roots, it can do so for any number; similarly, if a student has developed the ability to "think scientifically," he or she can do so with any content. In this formulation, domain knowledge is mainly important as grist for the mill—you need something to think about.

Skills and knowledge are not separate, however, but intertwined. In some cases, knowledge helps us recognize the underlying structure of a problem."

"At other times, we know that we have a particular thinking skill, but domain knowledge is necessary if we are to use it. For example, a student might have learned that "thinking scientifically" requires understanding the importance of anomalous results in an experiment. If you're surprised by the results of an experiment, that suggests that your hypothesis was wrong and the data are telling you something interesting. But to be surprised, you must make a prediction in the first place—and you can only generate a prediction if you understand the domain in which you are working. Thus, without content knowledge we often cannot use thinking skills properly and effectively."
