Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Students who completed a year of formal algebra instruction performed significantly better on verbally presented problems than on symbolic equations, in both samples. → Nathan 2001

q3 · i? · theoretical · r3
Research on problem-solving performance of ninth grade students in two samples (n1 = 76, n2 = 171) who had completed a year of formal algebra instruction. The article reports "statistically significant advantages for verbal problems in both samples (p < .01)"; no effect size is printed.
"Students’ performance on equations is less than 30%, while verbal problems are solved correctly over 50% of the time, leading to statistically significant advantages for verbal problems in both samples (p < .01)."

Related Claims¶
- Polya Method students outscore Dahmus Method students on the equation criterion for verbal problems
- Dahmus Method students translated phrases successfully but failed to combine them into a single solution equation
- Algebra ability level differences appear on both criteria with no treatment-by-ability interaction
- Baseline versus code-augmented performance differs significantly for story and symbolic representations but not word-equations, with small effect sizes — related
- Personalization to student interests improved accuracy on hard knowledge components involving algebraic expression-writing within the tutoring unit — related
- Typical verbal achievement tests may underestimate students' subject-matter knowledge because of a mismatch between the test's symbolic form and students' symbolic encoding — related
- Bilinguals may have a specific advantage in transferring understanding of novel symbolic rules to new contexts — related
