Rates of scientific literacy among American adults hover below 30 percent. More than a third of them aren’t convinced that the planet is warming, and only half think human activity is causing climate change, despite consensus among scientists that it is. Even long-settled subjects are still clouded by doubt: 30 percent of Americans say parents should be able to choose not to vaccinate their children; 53 percent think humans and dinosaurs coexisted; and 70 percent don’t believe in the Big Bang theory.
When I work with educators, I get asked on a regular basis, “What about the universities? What are they doing to prepare educators who can facilitate technology-infused learning environments that emphasize deeper cognitive complexity and greater student agency?” Unfortunately, I don’t have much to offer them.
I am rereading Teaching As a Subversive Activity, which is a phenomenal book if you haven’t read it. About halfway through the book, Postman and Weingartner discuss ‘closed’ versus ‘open’ systems of knowledge:
A closed system is one in which the knowables are fixed. Examples of this kind of system would include any in which most of its answers are either yes or no, right or wrong, clearly and without any other possibility. (p. 116)
Open systems may be thought of as situations in which there are degrees of ‘rightness,’ and in which a right answer today may well be a wrong answer tomorrow. (p. 117)
Most of what we do in school falls under the description of a ‘closed’ system. There is typically a right answer, the teacher (or the textbook or the learning software) knows it, and it’s up the student to ‘learn’ it and then spit it back correctly: Describe the water cycle. If 4x2 + 3 = 39, what is x? What is the capital of Delaware?
In life, however, much of what we do falls under the description of an ‘open’ system. We ask questions and make choices and devise solutions that seem right at the time given the particular context: What major should I choose? Should I look for a new job? Is she the one with whom I want to spend the rest of my life? Which car is best for our family? At another time, in another context, we might decide and act differently. This is true for both individual- and citizen-/policy-level decisions: Should we try to stop Russia from annexing Crimea? Are ethanol subsidies a good way to reduce our nation’s fuel dependence? Should I vote ‘yes’ for the school district referendum? When should we place limits on free speech?
Many argue that fixed knowledge items such as ’the water cycle’ or ‘4x2 + 3 = 39’ or ‘the capital of Delaware’ are the necessary parts that form a foundation for deeper, more cognitively complex thinking. And that’s often true. But it’s a whole nother matter to treat fixed items of knowledge as sacrosanct or to elevate them to the primary desired outcomes of schooling, particularly given the increasing presence of Internet-enabled learning contexts in which such items are easily and quickly accessible. Instead of treating content retention and procedural thinking as foundational floors from which we then build larger, more important edifices of learning, we have made them into almost-impermeable ceilings that drive teaching, curriculum, and assessment.
To fully prepare most students for life – and, arguably, to reengage many of them in the learning, not just social, aspects of their schooling – they need greater immersion in open systems of learning where questions are raised, answers aren’t fixed, and solutions are often contextual. This is true for all grade levels, not just secondary. So far most schools don’t do a great job with this. Instead, what schools usually do
in effect [is] to make closed systems of largely open ones. (p. 117)
We take areas of knowledge like science or government or language or health and we set them in stone – “yes or no, right or wrong, clearly and without any other possibility” – instead of bravely facing them – as they are in real life – as open opportunities for discussion, inquiry, problem-solving, and, yes, divergent learning and knowing.
A tremendous challenge for us as educators and policymakers is to stop reducing learning to convergent, ‘closed’ models of knowing and instead embrace the power and potential of more ‘open’ systems of knowledge and inquiry. This challenge is worth taking on because
very few problems of any great significance can be answered if they are approached from a ‘closed’-system point of view. (p. 117)
And goodness knows we have innumerable problems of great significance that would benefit from some fresh thinking…
