This distinction between "skills that are novel" and "skills that must be taught more intentionally and effectively" ought to lead policymakers to different education reforms than those they are now considering. If these skills were indeed new, then perhaps we would need a radical overhaul of how we think about content and curriculum. But if the issue is, instead, that schools must be more deliberate about teaching critical thinking, collaboration, and problem solving to all students, then the remedies are more obvious, although still intensely challenging.

To complicate the challenge, some of the rhetoric we have heard surrounding this movement suggests that with so much new knowledge being created, content no longer matters; that ways of knowing information are now much more important than information itself. Such notions contradict what we know about teaching and learning and raise concerns that the 21st century skills movement will end up being a weak intervention for the very students—low-income students and students of color—who most need powerful schools as a matter of social equity.

What will it take to ensure that the idea of "21st century skills"—or more precisely, the effort to ensure that all students, rather than just a privileged few, have access to a rich education that intentionally helps them learn these skills—is successful in improving schools? That effort requires three primary components. First, educators and policymakers must ensure that the instructional program is complete and that content is not shortchanged for an ephemeral pursuit of skills. Second, states, school districts, and schools need to revamp how they think about human capital in education—in particular how teachers are trained. Finally, we need new assessments that can accurately measure richer learning and more complex tasks.

Why would misunderstanding the relationship of skills and knowledge lead to trouble? If you believe that skills and knowledge are separate, you are likely to draw two incorrect conclusions. First, because content is readily available in many locations but thinking skills reside in the learner's brain, it would seem clear that if we must choose between them, skills are essential, whereas content is merely desirable. Second, if skills are independent of content, we could reasonably conclude that we can develop these skills through the use of any content. For example, if students can learn how to think critically about science in the context of any scientific material, a teacher should select content that will engage students (for instance, the chemistry of candy), even if that content is not central to the field. But all content is not equally important to mathematics, or to science, or to literature. To think critically, students need the knowledge that is central to the domain.

Because of these challenges, devising a 21st century skills curriculum requires more than paying lip service to content knowledge.

Advocates of 21st century skills favor student-centered methods—for example, problem-based learning and project-based learning—that allow students to collaborate, work on authentic problems, and engage with the community. These approaches are widely acclaimed and can be found in any pedagogical methods textbook; teachers know about them and believe they're effective. And yet, teachers don't use them. Recent data show that most instructional time is composed of seatwork and whole-class instruction led by the teacher (National Institute of Child Health and Human Development Early Child Care Research Network, 2005). Even when class sizes are reduced, teachers do not change their teaching strategies or use these student-centered methods (Shapson, Wright, Eason, & Fitzgerald, 1980). Again, these are not new issues. John Goodlad (1984) reported the same finding in his landmark study published more than 20 years ago.

Why don't teachers use the methods that they believe are most effective? Even advocates of student-centered methods acknowledge that these methods pose classroom management problems for teachers. When students collaborate, one expects a certain amount of hubbub in the room, which could devolve into chaos in less-than-expert hands. These methods also demand that teachers be knowledgeable about a broad range of topics and are prepared to make in-the-moment decisions as the lesson plan progresses. Anyone who has watched a highly effective teacher lead a class by simultaneously engaging with content, classroom management, and the ongoing monitoring of student progress knows how intense and demanding this work is. It's a constant juggling act that involves keeping many balls in the air.

Most teachers don't need to be persuaded that project-based learning is a good idea—they already believe that. What teachers need is much more robust training and support than they receive today, including specific lesson plans that deal with the high cognitive demands and potential classroom management problems of using student-centered methods.

Without better curriculum, better teaching, and better tests, the emphasis on "21st century skills" will be a superficial one that will sacrifice long-term gains for the appearance of short-term progress.

stress is known to have an impact on cognitive function, and this includes memory

For starters, stress can interfere with sleep, which we have already identified as important to memory. But stress also impacts the brain more directly in both positive and negative ways.

So what are some approaches to managing stress? Getting enough sleep and exercising regularly are an excellent starting point

Programming -OK, on the programming thing, here are my thoughts.In our curriculum our objective is not as much a specific LANGUAGE. One year I may use HTML with Javascript, this past year I used LSL — what I want kids to know that when they encounter programming and coding that there are certain conventions. Some are case sensitive, some are not. How do you find out how to add to what you know about programming? Do you know where to go to find prewritten code? Can you hack it to make it work to do what you want it to do?We spend about a week – two weeks but I require they know how to handcode hyperlinks and images – they are just too important.But to take 12 weeks or 6 weeks to learn a whole language – yes maybe some value – but to me the value is HOW is the language constructed or built. What are the conventions and how do I educate myself if I am interested in pursuing. What comes out of this time is kids who say either “I never want to do that” or “this is really cool, I love coding.”They are doing very simplistic work (although the LSL object languages were pretty advanced) but since we don’t have a full course nor time in our curriculum, I do see this as an essential part of what I teach.I’m not teaching it for the language sake but for the sake of understanding the whole body of how languages work – we talk about the different languages and what they are used for as part of Intro to Computer science and have an immersive experience.To me, this is somewhat a comprimise between leaving it out entirely or forcing everyone to take 12 weeks of it. I just don’t know where 12 weeks would go in the curriculum.

It’s a step backward. A 1:1 classroom done at least fairly well becomes a an intense learning environment. Students are engaged, empowered, active learners instead of sitting learning to be taught. It is an active process a far greater amount of the time (and this is one area I need to improve, is getting that and letting that happen more) and the feel of the classroom changes. People that visit pick up on that. It changes from a 1:1 laptop classroom into a learning environment that uses laptops and other tools to leverage learning.
