Subclaims¶

q2 i? Ninth-grade algebra students taught with the Polya Method achieved significantly higher equation (translation) scores than students taught with the Dahmus translation Method. → Bassler 1972

Evidence¶

Bassler 1972¶

Bassler, O. C.; Beers, M. I.; Richardson, L. I. (1972). Comparison of Two Instructional Strategies for Teaching the Solution to Verbal Problems. Final Report. George Peabody College for Teachers. https://eric.ed.gov/?id=ED075260

q2 · i? · causal · r2

Three-factor ANOVA (treatment x ability x test occasion, repeated measures on occasion) on equation-criterion scores of 48 ninth-grade girls, 8 per cell, after seven days of slide-tape instruction. The treatment main effect was significant (F = 20.30, p < .05), with "the PM subjects had a significantly larger mean score than the DM subjects on the equation criterion."

"Comparing this with the results reported in Table 2 indicates that the PM subjects had a significantly larger mean score than the DM subjects on the equation criterion."

Discussion¶

Learner Variables¶

• Algebraic Thinking — outcome: instruction changes it

• Polya and Dahmus methods do not differ on the problem solution criterion — related
• Students exposed to AI-generated responses achieved higher performance in solving quadratic equations than those taught through conventional teaching methods — related
• Ninth grade algebra students solve verbally presented problems better than symbolically presented problems
• On the problem solution criterion, verbal problem solving scores do not decline over four weeks and rise on the more complex problems — related
• Algebra ability level differences appear on both criteria with no treatment-by-ability interaction — related
