This phrase gave a hint into Don\u2019s outlook on society and the individual, which is built upon below.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><em>Why \u2018shared\u2019 knowledge matters<\/em><\/h3>\n\n\n\n<p>A great point that Don made within the podcast is that he could have easily, and perhaps more clearly, titled his book, \u2018Why <em>Shared <\/em>Knowledge Matters\u2019 instead of simply, \u2018Why Knowledge Matters\u2019. This is because his main point is that what&#8217;s important is not knowledge, but the fact that it\u2019s shared, and it\u2019s known that it\u2019s shared.&nbsp;<\/p>\n\n\n\n<p>When we know that knowledge is shared, we can improve the efficiency of our communication. The example that Don gave was of someone asking for directions on the subway. If someone is dressed up as a Bostonian and they ask a passerby, \u2018How do I get to central square?\u2019 the passerby will assume a certain amount of shared knowledge and answer simply, \u2018First stop on the subway\u2019. If someone is dressed up as a tourist and they ask the same question, they\u2019re likely to get a much more detailed answer.&nbsp;<\/p>\n\n\n\n<p>Another similar example is with teaching. If a coach and a coachee both know that they have shared knowledge about what a <em>cold call<\/em> is, the coach can say, \u2018That was a good opportunity for a cold call\u2019 when discussing a lesson. If this knowledge isn\u2019t shared, the coach will have to be much more explicit when describing this questioning technique.&nbsp;<\/p>\n\n\n\n<p>In short, <em>shared<\/em> knowledge improves both the accuracy and efficiency of communication.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><em>Challenging the dominant theory of development<\/em><\/h3>\n\n\n\n<p>One of Don&#8217;s other main points within the podcast was to challenge the dominant theory of development in American schools. This dominant theory posits that human beings are like plants, and that the human brain begins similarly to a seed in that it begins with all required information for its own healthy development.&nbsp;<\/p>\n\n\n\n<p>Don challenges this and suggests that the brain is actually more like the blank slate that John Locke was alluding to. That is, the brain requires inputs for its development, it doesn&#8217;t just develop naturally. Our bodies do develop in a natural way, and will do so without much external input. But knowledge and language require this external input, the knowledge required to thrive in modern society doesn\u2019t just naturally arrive in our brains as we make our way through life.&nbsp;&nbsp;<\/p>\n\n\n\n<p>To back up this claim, Don cited <a href=\"https:\/\/www.pnas.org\/doi\/abs\/10.1073\/pnas.0407088102\">this recent article<\/a> by Nir Kalisman and colleagues.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><em>Redefining individualism<\/em><\/h3>\n\n\n\n<p>Don defined individualism in an interesting way. He defined it within the scope of the tribe. That is to say that the question of individualism is a question of what it takes for the individual to flourish within the context of the tribe.<\/p>\n\n\n\n<p>This relates interestingly to the work of <a href=\"https:\/\/www.ollielovell.com\/errr\/billrogers\/\">Bill Rogers<\/a> and <a href=\"https:\/\/www.ollielovell.com\/errr\/tom-bennett-behaviour-management-running-the-room\/\">Tom Bennett<\/a>, who both emphasised within my discussions with them the fundamental desire of individuals to belong as a core driving force to behaviour. Therefore the question of how to promote individual flourishing (individualism) can be characterised as a question of how to support the individual to belong and flourish within the tribe. In his book, Don captures this with:<\/p>\n\n\n\n<p><em>The key task facing our elementary schools is to shift our emphasis from the goal of self-realisation to the goal of community &#8211; from child-centeredness to community-centeredness. No sensible person would disparage either goal. But the emphasis must shift decisively for the sake of the community and the individual child. (<\/em>pg. 2)<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Takeaways from <em>Why Knowledge Matters<\/em><\/h2>\n\n\n\n<p>There were three big and incredibly valuable ideas that I encountered in Don Hirsch\u2019s <em>Why Knowledge Matters<\/em>. We touched upon these three ideas in the podcast in various forms, but I will expand upon each of them in this summary.&nbsp;<\/p>\n\n\n\n<p>The three big ideas are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The danger of \u2018fadeout\u2019, and how it can only be avoided through a coherent and communal curriculum (as made clear through the French, Swedish, and German examples)<\/li>\n\n\n\n<li>The <em>Coleman Differential Effect<\/em>: Schooling can play the decisive role in closing achievement gaps, but only if it\u2019s good schooling<\/li>\n\n\n\n<li>Domain Immersion: Don\u2019s key recommendation for the building of a coherent and communal curriculum<\/li>\n<\/ul>\n\n\n\n<p>I\u2019m excited to share each of these takeaways with you below.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The danger of \u2018fadeout\u2019, and how it can only be avoided through a coherent and communal curriculum (as made clear through the French, Swedish, and German examples)<\/h2>\n\n\n\n<p>What is fadeout? Fadeout is the fading of beneficial effects of early schooling due to a lack of structure and coherence of later schooling.&nbsp;<\/p>\n\n\n\n<p>We are all familiar with this concept from our own lives. You start a learning project, maybe learning a language, exploring some area of history or geography, or reading a bit of philosophy or education research. You do some good learning in the early stages, but life gets in the way and the project is ultimately abandoned.&nbsp;<\/p>\n\n\n\n<p>A year or so later, you return to the same topic, but it\u2019s as if you had never even looked at it! You feel you remember nothing from your initial foray, and you need to start all over again.&nbsp;<\/p>\n\n\n\n<p>This is fadeout. Because of the way that our memories decay over time, we need multiple exposures to content, often in multiple contexts, in order to be able to remember knowledge, and crucially, to build upon it.&nbsp;<\/p>\n\n\n\n<p>But this isn\u2019t just an issue at the individual level, it\u2019s an issue at the national level. Irrespective of how structured and effective the early years of schooling are, if these early years aren\u2019t followed by a structured and coherent educational experience in later years, all of the hard earned gains in those early years can be lost.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><em>The case of Project Follow Through<\/em><\/h3>\n\n\n\n<p>One particularly striking example of fadeout from the US is <a href=\"https:\/\/en.wikipedia.org\/wiki\/Follow_Through_(project)\">Project Follow Through<\/a>. Project Follow Through, beginning in 1968, involved over 200,000 children spanning kindergarten to grade 3, and compared a total of 22 instructional programs. As Wikipedia states, this was the largest and most expensive research program ever undertaken in the United States, and it found that when it comes to building both basic skills and self-concept, Sigfried Englemann\u2019s model of Direct Instruction was the most effective approach of those implemented.&nbsp;<\/p>\n\n\n\n<p>But did these benefits last? A 1982 study followed up with about 1,000 students from the original Follow Through program and tested them several years after the initial program, now in grades 5 and 6. There were two key findings from Becker and Gersten\u2019s follow up study.&nbsp;<\/p>\n\n\n\n<p>Firstly, there was evidence that low-income students who received Direct Instruction through Project Follow Through performed better on standardised achievement tests in grades 5 and 6 than their peers who didn\u2019t receive this Direct Instruction. The authors write, \u2018Follow Through graduates often perform significantly higher than other low-income fifth and sixth graders in their communities, especially in the areas of reading decoding, math concepts, math problem solving, and science\u2019 (pg. 89). This is encouraging, and it means that significant learning gains were retained.<\/p>\n\n\n\n<p>The second main finding was that the gap between more and less affluent students that had been significantly reduced throughout Project Follow Through had again increased through the intervening years. Becker and Gersten report, \u2018without effective instruction which continues to build on these skills in the intermediate grades, the children are likely to lose ground against their middle-income peers.\u2019 (pg. 89).&nbsp;<\/p>\n\n\n\n<p>In respect to more complex concepts that these students encountered <em>after<\/em> Project Follow Through, the authors add, \u2018They are failing to master new computational skills (such as long division and complex multiplication), and are failing to develop their vocabularies and reading comprehension abilities at the rate of middle- and higher-income students. Limited English-speaking students appear to lose the most. In order for these children to become fully literate adults, it appears that they need high-quality instructional programs in the intermediate grades (and probably beyond).\u2019 (pg. 89)<\/p>\n\n\n\n<p>Put simply, even three years of fantastic instruction between kindergarten and Grade 3 is insufficient&nbsp; &nbsp; &nbsp; &nbsp; if it isn\u2019t followed by high quality instruction in later years. Without continued quality, we are going to&nbsp; &nbsp; see fadeout and significant portions of hard-won gains will be lost.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><em>France and the US<\/em><\/h3>\n\n\n\n<p>In chapter seven of <em>Why Knowledge Matters<\/em>, Hirsch draws parallels between policy changes and educational outcomes in France and the US. Hirsch writes that US education reforms in the 1930s that advocated for a progressive move away from a communal curriculum lead to national test results declining markedly from the 30s to the 50s. Markedly, there was a fall in verbal scores throughout the 1960s to 1970s which precipitated the 1983 <em>A Nation at Risk<\/em> report.&nbsp;<\/p>\n\n\n\n<p>Let us now consider the French example. Originally, France had one of the most communal, shared, specific, and structured education systems in the world. This system was traditionally based on the principles of universalism, uniformity, and equality of opportunity. However, France broke from these communal principles in 1981 with their establishment of <em>zones d\u2019e \u0301ducation prioritaire<\/em>. These zones were designed to enact the principle of positive discrimination, and this focus on priority education has remained from those first 1981 reforms till the present, in addition to being relaunched with vigor in 2006. This movement away from communalism was further strengthened by the Education Policy Law of July 10th, 1989 (known as Loi Jospin). Article 17 of this initiated the establishment of University Teacher Training Institutes that emphasised the placement of students at the centre of teachers\u2019 thought and action. What this meant in practical terms was that each local district would determine its own subject matter and curriculum in line with its own specific aims and local context. In essence, a move away from the shared national curriculum that had been the mainstay of French education for over a century.&nbsp;<img loading=\"lazy\" decoding=\"async\" src=\"blob:https:\/\/cosinus.opalstacked.com\/1a219fea-b3ea-4866-a404-d435705dc265\" width=\"373\" height=\"491\"><\/p>\n\n\n\n<p>Hirsch suggests that French national data can be compared to observe the impact of these changes. The following figure shows the decline in results between 1987 and 2007 based upon national soundings of student achievement conducted by the French Ministry of Education (found on pg. 154 of <em>Why Knowledge Matters<\/em>).<\/p>\n\n\n\n<p>Compounding this, French academic Paola Mattei writes that,&nbsp;<\/p>\n\n\n\n<p><em>In 2009, the government administered exams in French reading and math to assess student achievement, comparing the RRS and RAR schools (which receive the additional funding through positive discrimination reforms) with all other schools. At the end of primary school 79.4% of students were reading at or above the standard competency level in RRS schools, 76.6% in RAR schools, and 89.9% in all other schools. At the end of Coll\u00e8ge, the gap widened with competency levels of 68% in RRS schools, 50.6% in RAR schools, and 81.6% in all other schools.<\/em><\/p>\n\n\n\n<p>In essence, the movement away from a communal curriculum in both the US and France has led to a situation whereby less advantaged students are <em>supposed <\/em>to have more support, districts are <em>supposed<\/em> to tailor instruction and curriculum to local needs, and achievement gaps are <em>supposed<\/em> to be closed. However, the net effect in both countries has been a drastic decline of educational outcomes at all levels, even for our top students and, perhaps most worryingly, a significant increase in the gap between the achievement of more and less affluent students.&nbsp;<\/p>\n\n\n\n<p>What has this all got to with fadeout? Throughout this whole time period, French preschooling has remained incredibly communal, structured, and coherent. See an example of it here: <a href=\"https:\/\/www.youtube.com\/watch?v=bwfBxPfhcrQ\">Ecole maternelle on YouTube<\/a>. When this was backed up by a structured and coherent curriculum at the national level, the gains made in French preschools were compounded throughout French primary and high school. Unfortunately, since the movement away from a centralised national French curriculum, many of the gains made in these excellent preschools are now lost as students move into primary school.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><em>Sweden and Germany<\/em><\/h3>\n\n\n\n<p>Hirsch further adds weight to his argument with the contrasting examples of Sweden and Germany. In 1994, Sweden decided to hand over responsibility regarding curriculum and syllabus to the discretion of local schools. In 2014, Professor Leif Lewin undertook an analysis to evaluate the impacts of this change, which he summarised with, \u2018the basic idea of 1994 law was that henceforth teachers and principals are considered to be in the best position to design the curriculum, because they best know the local conditions.\u2019 (section 2.5). Sound familiar?<\/p>\n\n\n\n<p>Over a similar time period, and in response to surprisingly bad results in 2000, which the country termed, \u2018<em>der PISA Schock<\/em>\u2019, Germany began to adopt a well-defined national curriculum.&nbsp;<\/p>\n\n\n\n<p>Hirsch presents the following table to illustrate the contrasting impacts of these opposite curricular reforms (from pg. 154):<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"702\" height=\"327\" src=\"https:\/\/cosinus.opalstacked.com\/wp-content\/uploads\/2026\/03\/image.png\" alt=\"\" class=\"wp-image-30\" srcset=\"https:\/\/cosinus.opalstacked.com\/wp-content\/uploads\/2026\/03\/image.png 702w, https:\/\/cosinus.opalstacked.com\/wp-content\/uploads\/2026\/03\/image-300x140.png 300w\" sizes=\"auto, (max-width: 702px) 100vw, 702px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><em>Reflecting upon fadeout and the importance of a structured, coherent, and communal curriculum.&nbsp;<\/em><\/h3>\n\n\n\n<p>Let\u2019s step back for a moment to consider these important ideas from a more everyday perspective. In addition to Hirsch\u2019s position being very well argued, and supported with large scale national experiments, they also seem to me to hold well from a common sense perspective.&nbsp;<\/p>\n\n\n\n<p>Coherence: The building of knowledge is an accumulative process that occurs over time, whereby the learner must take each new piece of information and integrate it into what they already know. For this to happen, what the learner already knows, and what they\u2019re encountering in the new learning episode, must be sufficiently related for the new information to \u2018stick\u2019. This is what we mean by \u2018coherence\u2019. What is the definition of coherence? Coherence: \u2018the quality of forming a unified whole\u2019. If we serve up to students a curriculum that has a high level of coherence, both across year levels, and across subjects within year levels, we provide them with the best opportunity to develop a rich, complex, and deep web of knowledge that is likely to set them up for success, as well as standing the test of time.&nbsp;<\/p>\n\n\n\n<p>Structured: A structured curriculum is one that logically builds over time and that systematically revisits content with sufficient frequency such that it is retained by students. Coherence and structure naturally go together.<\/p>\n\n\n\n<p>Communal: A curriculum is communal when it is applied at a large scale, across many schools and systems. Communalism is important for several reasons. Firstly, as Hirsch\u2019s position implies, it provides all of the young people within a society with a shared body of foundational knowledge, knowledge that is integral to their country and culture. This is the foundation of a cohesive nation, which itself is foundational to political stability, and individual and collective prosperity. Secondly, communalism leads to economies of scale. Without a shared curriculum we have isolated teachers, and isolated schools, trying to reinvent the wheel and making lesson plans, projects, activities, and worksheets that will only be used a few times until the next teacher or leader comes along and instigates new ones. This is unsustainable and results in both a huge amount of wasted time and effort, and lower quality resources. If we have a national or large-scale approach, it makes sense to make significant investments into high quality curriculum (hiring the best writers, field-testing resources, and iteratively improving activities and projects). This results in incredibly high quality resources, such as those produced by the <a href=\"https:\/\/www.coreknowledge.org\/\">Core Knowledge Foundation<\/a>. (This is something that I\u2019m increasingly interested in the importance of\u2026 watch this space!)<\/p>\n\n\n\n<p>When we have such a curriculum, we can reduce fadeout, because what a student learns in one year will be built upon in subsequent years. Further, if a student changes schools, or a teacher changes schools, there\u2019s no starting from scratch; they can simply pick up from where they left off because they will be working from the same curriculum, and likely even the same textbooks!<\/p>\n\n\n\n<p>Hirsch\u2019s arguments for communality, structure, and coherence are backed up by evidence, but they also just make sense. I\u2019ll close this section with some quotes from Hirsch himself:<\/p>\n\n\n\n<p><em>\u2018Only by systematically imparting to all children the knowledge that is commonly possessed by successful citizens can all children gain the possibility of success &#8211; \u201csuccess \u201c understood as becoming a person with autonomy, who commands respect, has a communal voice that can write and speak effectively to strangers, can earn a good living, and can contribute to the wider community.\u2019 (pg. 2)<\/em><\/p>\n\n\n\n<p><em>\u2018In a system with a specific and coherent curriculum, the work of each teacher builds on the work of teachers who came before.\u2019 (pg. 37)<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The <em>Coleman Differential Effect<\/em>: Schooling can play the decisive role in closing achievement gaps, but only if it\u2019s good schooling<\/h2>\n\n\n\n<p>Here I emphasise a smaller point, but an equally important one. Debates often rage about the importance of schooling, and the potential impact that it can have. Often we debate the relative influence of background factors: poverty, hardship, language backgrounds that are not the dominant language. But in <em>Why Knowledge Matters<\/em>, Hirsch highlights and names an important effect that is often overlooked in these debates, The Coleman Differential Effect.&nbsp;<\/p>\n\n\n\n<p>The Coleman Differential Effect relates to the key, but underreported finding, of the Coleman Report. Coleman\u2019s 1966 report included almost 650,000 US students and teachers in more that 3,000 schools and is often misreported as having the finding, \u2018Schools don\u2019t matter, families do\u2019.&nbsp;<\/p>\n\n\n\n<p>However, Hirsch writes (pg. 95):&nbsp;<\/p>\n\n\n\n<p><em>[A] 2010 reanalysis summarised its findings as follows: \u201cOur results suggest that schools do indeed matter, in that when one examines the outcomes across the national sample of schools, fully 40% of the differences in achievement can be found between schools. Even after statistically taking into account students\u2019 family background, a large proportion of the variation among true school means is related to differences explained by school characteristics.<\/em><\/p>\n\n\n\n<p>Hirsch quotes from the original report which exemplified the language of its day (pg. 96-97):<\/p>\n\n\n\n<p><em>The average white student&#8217;s achievement seems to be less affected by the strength or weakness &nbsp; &nbsp; of his school\u2019s facilities, curriculum, and teachers than is the average minority pupils. To put it another way, the achievement of minority pupils depends more on the school they attend than does the achievement of the majority pupils. Thus, 20 percent of the achievement of Negroes in the South is associated with the particular schools they go to, whereas only 10 percent of the achievement of whites in the South is. Except for Oriental Americans, this general result is found for all minorities. The inference might then be made that improving the school of a minority pupil may increase his achievement more than would improving the school of a white child increase his. Similarly, the average minority pupil\u2019s achievement may suffer more in a school of low quality than might the average white pupil\u2019s. In short, whites and to a lesser extent Oriental Americans, are less affected one way or the other by the quality of their schools than are minority pupils. This indicates that it is for the most disadvantaged children that improvements in school quality will make the most difference in achievement.<\/em><\/p>\n\n\n\n<p>Hirsch concludes:<\/p>\n\n\n\n<p><em>Coleman\u2019s insight that school quality affects disadvantaged students twice as much as advantaged children deserved to be memorialized as the \u2018Coleman Differential Effect\u2019<\/em><\/p>\n\n\n\n<p>In summary, school matters, but school <em>really<\/em> matters when schooling is effective. Further, the benefit of a high quality education is roughly twice as large for disadvantaged students than it is for advantaged students.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Domain Immersion: Don\u2019s key recommendation for the building of a coherent and communal curriculum<\/h2>\n\n\n\n<p>We\u2019ve now heard the argument that we need a structured, coherent, and communal curriculum in order to avoid fadeout. We also know that schooling can matter a lot, especially for our most disadvantaged students, but only if it\u2019s <em>quality<\/em> schooling.&nbsp;<\/p>\n\n\n\n<p>In line with this, I\u2019d like to close this summary by sharing Don\u2019s main suggestion for designing such a curriculum, <em>Domain Immersion<\/em>. Domain immersion is the act of providing students with multiple opportunities for deep engagement with knowledge, vocabulary, ideas, and skills in relation to a specific domain or topic, over an extended period of time. Don shares such an example as follows:<\/p>\n\n\n\n<p><em>\u2018An effective preschool or primary teacher will introduce the subject &#8211; let\u2019s say \u201c plants and farms\u201d &#8211; and tell stories about plants and farms and ask questions about them not just on one day,&nbsp; but over several. Of course, it&#8217;s not all verbal, there will be hands on planting of some quick germinating seeds! I chose this example, because many American preschools already do plants! At first, there will be a big difference between children who already know something about plants and food and associated words, and those who do not. Gradually, though, over several days, the subject becomes familiar to all. The most impoverished child will begin to answer questions about plants and farms, and will know implicitly what soil is, what the parts of a plant are,&nbsp; how many of our foods come from plants, what is needed to make plants grow &#8211; to take a simple example &#8211; with plenty of stories about the countryside.<\/em><\/p>\n\n\n\n<p><em>Because all of the children are gradually coming to understand the stories and their sentences, they will also be learning general words like moreover, however, and nonetheless. When they learn about kings and queens, they will learn evil and generous and secure. Some of those words were already known by advantaged children but in the course of a few days they were also begun to be known by disadvantaged ones. The coherence series of stories about kings and queens will have enabled disadvantaged children to catch up a bit. They will have learnt words that were already familiar to advantaged children. They will learn relatively more words because they began far behind\u2019.
