WKM (2016) — Appendix Ii
Appendix Ii
Appendix II provides a methodological overview of the 2008 French study (Note d’Information 08-38) which tracked a twenty-year decline in student performance between 1987 and 2007. Hirsch uses this data to argue that reading is more sensitive to school-based knowledge curricula than math because reading relies heavily on vocabulary and general knowledge acquired in the home, making school-provided knowledge the primary lever for equity.

The Equity-Subject Correlation Chain strong
The overall decline in mathematics performance in France between 1987 and 2007 was more than twice as large as the decline in reading.2 ev
↓
The increase in the performance spread between demographic groups was quantified as .1 standard deviation for math and .4 standard deviation for reading.
↓
The decline in educational equity, measured by the spread between demographic groups, was four times greater in reading than in math in France.1 ev
↓
Mathematics is primarily a school subject where instructional effectiveness tends to decline for all students uniformly.
↓
Reading performance is dependent upon general knowledge and vocabulary size, making it both a school and a home subject.
↓
Poor schooling has a significantly greater negative impact on equity in reading than it does on equity in math.1 ca
The Social Mandate Chain strong
A knowledge-based curriculum is far more effective at promoting equity than a skills-based curriculum.1 ca
↓
Between 1987 and 2007, France experienced a simultaneous decline in the effectiveness of instruction for both knowledge acquisition and decoding skills.
↓
Schools must maximize their contribution to student knowledge and vocabulary in order to fulfill the social aim of equal opportunity.1 ca
The Curricular Reform Chain moderate
Decimal multiplication and division were removed from the French primary curriculum between 1987 and 2007.
↓
The adoption of whole-language methods led younger French teachers to reject the more effective phonics method for teaching decoding.
↓
Direct word study and skills-based curricula cannot achieve a significant increase in a student's vocabulary size.
↓
A knowledge-based curriculum is far more effective at promoting equity than a skills-based curriculum.1 ca
French Writing Quality Evidence Chain moderate
Counter-Arguments (5)
empirical challenge (1)
A knowledge-based curriculum could theoretically widen the gap if advantaged students, who already have high knowledge, benefit from the rich content at an even faster rate than disadvantaged students (the Matthew Effect).
alternative explanation (3)
The greater negative impact on reading equity might be due to increased linguistic diversity in the French student population between 1987 and 2007, rather than the intrinsic nature of reading as a 'home subject.'
The increase in writing errors may be primarily due to the increased influence of digital communication and 'texting' culture on ten-year-olds between 1987 and 2007, rather than changes in school curriculum.
The decline could be attributed to a general increase in the number of students from non-French speaking households entering the public school system during this twenty-year period.
value disagreement (1)
Focusing schools exclusively on maximizing vocabulary and knowledge acquisition to serve 'equal opportunity' may neglect other vital social aims of schooling, such as social-emotional development or critical inquiry.
Logical Gaps (3)
Unstated assumptions required for the arguments to work.
Establishing that the increased reading gap was caused by the curriculum shift specifically, rather than external factors that disproportionately affected reading (e.g., changes in home literacy environments).
significant
Evidence that the 'skills-based' methods adopted by teachers were the primary reason for the decline, rather than a decline in the quality of teacher training or student motivation.
significant
Evidence that the student population in 2007 was demographically and linguistically comparable to the 1987 population.
