Beginning in 1990s, Hirsch began publishing books in the "Core Knowledge Grader Series" which the Foundation describes as "an engaging, illustrated guide to the essential knowledge outlined in the Core Knowledge Sequence". This series of books was received well by parents educating children at home, and it has been adopted by many school systems.
Sol Stern, a senior fellow at the Manhattan Institute who has written extensively on education reform, wrote in 2013 that Hirsch was "the most important education reformer of the past half-century."

Estimator
In statistics, an estimator is a rule for calculating an estimate of a given amount based on observed data: thus the rule (the estimator), the amount that is being measured (the estimand) and its result (the estimate) are different.
An estimator of a parameter formula_1 is often written as formula_2. If the expected value of the estimator is equal to the parameter, then the estimator is called unbiased. Otherwise, it is called biased.
Statistical parameter
A statistical parameter or population parameter is an amount put into the probability distribution of a statistic or a random variable. It can be thought of as a numbered amount of a trait of a statistical population or a statistical model.
A statistical parameter is different from its estimator in that the parameter is a fixed amount, while the value of an estimator changes according to some probability distribution. The notations formula_1 (for the parameter) and formula_2 (for the estimator) are often used to clarify this distinction.
Efficiency (statistics)
In the comparison of statistical procedures, efficiency is a measure of an estimator's quality. This would be about the estimator of an experimental design, or of a hypothesis testing procedure. Basically, a more efficient estimator, experiment, or test needs fewer observations than a less efficient one to get a given performance.
Method of moments (statistics)
In statistics, the method of moments is a method of estimation of population parameters.
Suppose that the problem is to estimate formula_1 unknown parameters formula_2 describing the distribution formula_3 of the random variable formula_4. Suppose the first formula_1 moments of the true distribution (the "population moments") can be expressed as functions of the formula_6s:
Suppose a sample of size formula_8 is drawn, and it leads to the values formula_9. For formula_10, let
be the "j"-th sample moment, an estimate of formula_12. The method of moments estimator for formula_13 denoted by formula_14 is defined as the solution (if there is one) to the equations:
The method of moments is simple and gets consistent estimators (under very weak assumptions). However, these estimators are often biased.
