2006 · The Knowledge Deficit
F. D. Smith's longitudinal analysis comparing reading scores of a Core Knowledge school against a control school from kindergarten to grade six.
direct When children are offered coherent, cumulative knowledge from preschool on, they become good readers.
Warrant (implicit): A longitudinal correlation between a specific curriculum and reading scores in a controlled comparison identifies that curriculum as the superior method for developing literacy.
could fail ifThe control school may have been using a particularly ineffective 'whole language' approach, making the Core Knowledge school look superior by comparison regardless of its specific content.
2010 · The Making of Americans
Fred Smith's 2003 study tracing four cohorts through six grades, showing Core Knowledge students significantly outperformed control schools in reading and math.
direct Both advanta ged and disa dvantaged st udents in Co re Knowledge schools outp erform peers in control s chools on st andardized r eading and m ath tests.
Warrant (implicit): Standardized test scores from longitudinal cohort studies are reliable indicators of the efficacy of a specific pedagogical philosophy across different socioeconomic tiers.
could fail ifThe 'Hawthorne Effect,' where the novelty of a new program and the increased attention given to teachers during a study lead to temporary gains that dissipate once the program is standardized.
Smith's stud y comparin g Core Know ledge schoo ls and cont rol schools in reading , math, and language g ains.
direct Both advanta ged and disa dvantaged st udents in Co re Knowledge schools outp erform peers in control s chools on st andardized r eading and m ath tests.
Warrant (implicit): Gains in standardized math and language scores are an accurate proxy for the overall intellectual development and knowledge acquisition provided by a curriculum.
could fail ifTeaching to the test or narrowing the curriculum to specifically match the items on the Stanford 9 TA tests can create inflated scores that do not translate to broader academic competence.
