> A child sits through about 16,000 classroom hours from primary school through high school. In this enormous receipt, the time actually spent on 'chunk installation'—operating things yourself, making mistakes, being corrected, trying again—is only a small fraction. This is not the failure of any individual teacher, nor of any particular reform. It is the original shape of this configuration.

Part 1: What Does a 'Hardware Audit' Actually Audit?
A Receipt, Twelve Years Long
Set aside what schools *should* teach, and look only at where resources actually go.
A child's twelve years of basic education come with a heavy receipt:
| Item | Quantity | Notes | |------|----------|-------| | Classroom hours | ~16,000 | 6 class periods/day, 200 days/year | | Parental hours invested | Thousands | Homework tutoring, school communication, admissions anxiety | | Dedicated teacher attention | <30 min/week | Averaged per student | | Public expenditure | ~200,000+ RMB | Estimated full-cycle cost of public education in a tier-1 Chinese city |
The point of this receipt is not how much was spent, but *where it went*.
Chunk Installation
> Note: The original author defines 'chunk installation' as the loop of *operate it yourself → make a mistake → get corrected promptly → try again*. Not listening to lectures, not taking notes, not taking exams—it is the act of handling knowledge with your own hands, turning 'knowing' into 'being able to use'.
Cognitive science has mature research on this loop. Benjamin Bloom's 1984 'Two Sigma Problem' found that students receiving one-on-one tutoring outperformed traditional classroom students by two standard deviations—equivalent to moving from a C to an A. VanLehn's 2011 meta-analysis confirmed that human one-on-one tutoring yields an effect size of roughly 0.8 standard deviations. K. Anders Ericsson's 'deliberate practice' tradition further emphasizes that immediate feedback is irreplaceable in skill formation.
These studies point to the same conclusion: real learning happens in the short loop of 'error-correction-retry', not in the long pipeline of 'listen-memorize-test'.
The problem: of those 16,000 classroom hours, how much does this short loop occupy? The answer is small. In a class of fifty, a teacher can give one-on-one feedback only a handful of times per lesson. Most of the time, students are 'listening' and 'recording', not 'doing' and 'fixing'. Chunk installation is structurally squeezed out of the classroom.
The Eight-Function Spectrum of Education
The original author arranges eight functions of education along a spectrum, ranked by a single criterion: can the function be reliably delivered at scale, standardized, under exam conditions?
| Scale-friendly end | Middle ground | Scale-unfriendly end | |--------------------|---------------|----------------------| | Workforce preparation | Basic knowledge transmission | Chunk installation | | Social sorting | Cultural transmission | Judgment of persons | | Childcare (custody) | | Curiosity preservation |
Key insight: What gets measured gets resourced; what goes unmeasured gets structurally squeezed out.
Exams can measure memory and calculation, so schools excel at teaching memory and calculation. Exams cannot measure 'how to decompose an unfamiliar problem', so schools don't teach it—not because they don't want to, but because this configuration inherently cannot.
The existence of the private tutoring market is itself evidence: it fills not gaps in teaching quality, but functions schools *structurally cannot deliver*. What parents buy is not 'more school', but 'a different form'—small classes, one-on-one attention, immediate feedback, customized paths. These are precisely the conditions chunk installation requires.
Schools as an 'Organ' in a Larger Arrangement
The original text states it bluntly: schools are not failing; they are doing what they were structurally chosen to do.
Schools are an organ in the roughly 150-year-old arrangement of 'state · capital · family · next generation'. Schooling is not education itself—only one form of it, a form extremely compressed for scale and standardization.
Eugen Weber's *Peasants into Frenchmen* documented this process: 19th-century European nation-states used schools as tools of 'protocol synchronization', turning scattered peasants into unified citizens. Schools were never designed to maximize each individual's potential—they were designed to fit large numbers of people into a shared template.
Bowles & Gintis's 1976 *Schooling in Capitalist America* and Bourdieu's cultural capital theory further identify a hidden function: class reproduction. Using seemingly fair 'uniform standards', schools allocate children of different classes to different social positions. Exams are not neutral measuring instruments—they are allocation instruments.
Michael Spence's 1973 signaling theory and Kenneth Arrow's 1973 screening theory make the logic explicit: the core value of a diploma is not 'what you learned', but 'sending employers a recognizable signal'. Once the signal is clear enough, employers don't need to know your actual ability—only that you 'passed the filter'.
Goodhart's Law: When a Metric Becomes a Target
Charles Goodhart (1975) and Donald Campbell (1976) independently articulated what is now called the Goodhart-Campbell Law: when a measure becomes a target, it ceases to be a good measure.
Education is a perfect laboratory for this law.
- Test scores were meant to indicate 'learning outcomes'. Once scores became the target, learning became 'how to score high'.
- Admission rates were meant to indicate 'educational quality'. Once admission rates became the target, schools became 'sorting factories'.
- Diplomas were meant to signal 'capability'. Once diplomas became the target, education became a 'credential arms race'.
