RE (2024) — Appendix Iv

Appendix Iv

The author argues that literacy is fundamentally an interpretive act, rooted in the philosophical field of hermeneutics, rather than a technical general skill. Because reading requires the sharing of unstated background knowledge to achieve an identity of meaning between author and reader, the move toward individualized, content-diverse curricula and quantitative 'readability' metrics has systematically undermined both literacy and national social cohesion.

empirical challenge (2)
Even if reading is interpretive, there are clearly general cognitive processes (like working memory capacity, syntactic processing, and decoding fluency) that act as 'general skills' across all domains of text.
Targets: The notion that reading ability is a general skill with measurable gen...
Cognitive strategies like 'monitoring for understanding' or 're-reading' are general skills that help readers tackle unfamiliar knowledge-rich texts across different domains.
Targets: Reading, after basic decoding is mastered, is a shared-knowledge-speci...
alternative explanation (4)
The 'diversity' of content may increase engagement and relevance for marginalized groups, potentially improving individual reading outcomes even if it reduces a single 'common' national knowledge base.
Targets: The introduction of diverse content for diverse students has diminishe...
The verbal decline in the 1950s and 60s could be attributed to the rise of television and visual media, which reduced the time children spent engaged with complex print materials, independent of school curriculum.
Targets: The 20th-century decline in American literacy was caused by the child-...
The SAT score decline in the 1960s is widely attributed to the democratization of the test-taking pool (the 'compositional effect'), as more students from diverse socio-economic backgrounds began taking the exam.
Targets: The implementation of child-centered education in the 1940s led to a c...

value disagreement (2)
National unity in a pluralistic democracy is better served by a shared commitment to democratic processes and rights rather than a shared inventory of specific cultural facts.
Targets: Shared background knowledge is a necessary prerequisite for national u...
In a pluralistic democracy, having 'adults' decide a specific curriculum content risks political indoctrination or the exclusion of minority perspectives, which 'natural' development ostensibly avoids.
Targets: Adults have a duty and responsibility to decide the specific content o...
methodological concern (2)
While the decline may have started before full integration, the expansion of the test-taking pool to include a broader socio-economic range of students during the mid-20th century could naturally lower average scores without implying a decline in the quality of instruction.
Targets: The American verbal decline in the 1950s and 60s was not caused by rac...
Readability formulas were never intended to be exhaustive measures of meaning, but rather practical tools for ensuring students aren't overwhelmed by word length and syntactic density.
Targets: Readability formulas are flawed because they omit elements like implic...
scope limitation (1)
State-mandated topic sequences may lead to a 'narrowing of the curriculum' where teachers focus only on tested topics, excluding emerging subjects or local interests.
Targets: State legislatures and state education officials should enact the Shan...
internal inconsistency (1)
Allowing local choice of materials risks re-introducing the very 'content incoherence' the Shanker Principle seeks to fix, as different materials may emphasize different aspects of the same topic.
Targets: Leaving the choice of materials of instruction for specific topics to ...

Unstated assumptions required for the arguments to work.

The introduction of diverse content was the primary reason for the decline in shared knowledge, rather than other factors like changing media habits or teaching quality.
critical
Mutual understanding (identity of meaning) between individuals is the primary causal driver of social cohesion and national unity.
significant
A statewide curriculum framework (The Shanker Principle) is the most effective way to provide the specific shared background knowledge required for literacy.
significant
A child's 'natural development' in an unknown future world cannot, by definition, include the specific historical and cultural content required for literacy.
significant
The 'shared knowledge' measured by the AFQT is the same 'shared knowledge' required for high-income professional participation.
minor
Establishing that no other major societal changes in the 1940s (e.g., shifts in family structure or media consumption) could have caused the same longitudinal effect.
