q3 i? Across three studies meeting WWC group design standards, Odyssey® Math showed a potentially positive effect rating on mathematics achievement: one statistically significant positive effect, one substantively important positive effect, and one indeterminate effect. → wwc-rating-1

q3 · i? · quant-synthesis · r1

Systematic review synthesis of three studies meeting WWC group design standards. The review concludes "one study showed a statistically significant positive effect, one study showed a substantively important positive effect, and one study showed an indeterminate effect," yielding the potentially positive effects rating.

"Thus, for the mathematics achievement domain, one study showed a statistically significant positive effect, one study showed a substantively important positive effect, and one study showed an indeterminate effect."

• Everyday Mathematics® has potentially positive effects on mathematics achievement for primary students, with a substantively important but statistically non-significant effect size of 0.27 — related
• Cornelius (2013) finds a positive, statistically significant effect of Odyssey® Math versus teacher-directed supplemental instruction on STAR Math scores — a narrower finding that bears on this claim
• The evidence base for Odyssey® Math's mathematics achievement effects is rated medium to large, based on three studies of 2,768 students in 41 schools — related
