I’m not one to do New Year’s resolutions—why set myself up for failure? But I do like to take a little time over the holidays to reflect on the year.
For me, the highlight of 2014 was attending the Politico 50 reception with E. D. Hirsch, who shared the No. 8 spot on Politico’s list of “thinkers, doers, and dreamers” with David Coleman. Most striking as we mingled was the depth and ease of the conversation. For Prof. Hirsch and me, at least, this was a room full of strangers. No matter. The topic could be the Iranian revolution or United States v. Windsor or technology’s potential impact on opportunity to learn; we all possessed enough common knowledge to converse seriously.
Whether at home, at school, at the library, or online, somehow we all acquired a definite core of knowledge. As a result, it did not matter that we had just met, were from all over the US, and specialized in different fields—we understood each other. The evening was a microcosm of how a democracy ought to be. Each of us had our personal interests and individual expertise; and each of us had enough knowledge in common to be able to discuss important topics. That’s not to say we agreed on those topics. Differing views were expressed and, in a couple of instances, vigorously debated.
The heart of a democracy is the ability to communicate with fellow citizens across space, time, and individual differences. Especially in a country as large and diverse as ours, that ability to communicate depends on all of us sharing a core of knowledge. That core does not mean we will agree, but it gives us a platform for being able to understand each other.

Communicating across time and place requires shared knowledge (image courtesy of Shutterstock).
No one kernel of knowledge may matter; but collectively, this core of knowledge divides the citizens with full access to civil society from the disenfranchised. It is essential for literacy, grasping analogies, critical thinking, and learning yet more (and more easily). Recent research shows that such knowledge is a powerful factor in social mobility, more powerful than parents’ education or school selectivity by one’s early 40s.
Most of us lucky enough to have learned this core of knowledge seem not to appreciate just how often we rely on it. At work, at the coffee shop, catching up on the news, we draw on and add to our vast stores of knowledge constantly. Neither news anchors nor neighbors provide all the details; they give you what’s new, and your store of knowledge plugs the holes. Even better, our shared knowledge is a source of strength. From the celebration of the Star-Spangled Banner that took place in Baltimore in September (another highlight of 2014 for me) to “one giant leap for mankind” 45 years ago, there are certain events, concepts, and people that cause a flood of images and ideas among the education haves. That flood is instantaneous. It offers both an anchor to steady us and a foundation on which to build. The simple words “I have a dream” can be overwhelming. Joyous. Sorrowful. Hopeful.
Well, I too have a dream. It is for everyone to have the core of shared knowledge that facilitates communication and invites all to be full participants in civil society. Yes, we have a long way to go. But at least people are starting to recognize that E. D. Hirsch’s great idea—that we could identify essential knowledge and create a curriculum to teach it to all children—is essential for equal opportunity. It’s egalitarian, not elitist, and it guarantees that everyone gets to study the arts, sciences, and humanities. Nor does it interfere with unique pursuits: If we spread that core of shared knowledge over several grades, there’s plenty of time left each year for students to learn content of local import and pursue their individual interests.
If you know of a district that shares my dream, please let me know: lhansel@coreknowledge.org. The Core Knowledge Foundation is seeking a district with the courage to close the achievement gap by implementing a content-rich, coherent, cumulative curriculum (including art, music, civics, and all the other important things that too often are neglected these days) in all of its elementary schools. While Core Knowledge would like to work with the district in creating the curriculum, it need not follow the Core Knowledge Sequence. The curriculum would have to be rigorous, coherent, and cumulatively build knowledge and skills. School entry is when the achievement gap is the smallest. By addressing vocabulary and knowledge disparities from the very beginning of schooling (mainly through engaging read-alouds, discussions, and projects), we can close the gap by the end of elementary school.
In the Core Knowledge community, we have individual schools that achieve terrific results with all of their students. We believe the results would be even better if the effort were districtwide. Teachers would be able to collaborate across schools; after a few years of shared problem solving and visiting each other’s classes, they would have world-class curriculum and pedagogy. They could even engage in their own form of Japanese lesson study. In addition, student mobility would be less of a problem, because children would not be completely lost academically when they changed schools within the district.
My words are neither eloquent nor enduring, but they are sincere. Let’s work together to give all children the broad, rich knowledge they need to become productive, responsible, engaged citizens.
