Subclaims¶

q3 i? After treatment, 77% of the ER group had visited a bookstore versus 60% of the no-ER group, a significant difference; the follow-up difference was not significant. → Rodrigo 2014 q3 i? Six months after treatment the ER group still visited a library more often than the no-ER group, a statistically significant difference. → Rodrigo 2014 (2)

Evidence¶

Rodrigo 2014¶

Rodrigo, V., Greenberg, D., & Segal, D. (2014). Changes in reading habits by low literate adults through extensive reading. Reading in a Foreign Language, 26(1), 73-91. http://nflrc.hawaii.edu/rfl

q3 · i? · causal · r2

Post-treatment Chi-square on bookstore-visit frequency; the article reports the difference as significant with "Eta = .176" but no standardized effect size in d, g, or r form, so no magnitude is coded. At follow-up the ER group still visited more (74% vs. 57%) but the difference was not significant (p > .05).

"After treatment, 77% of the ER group had been to a bookstore to look at or buy books versus 60% of the no-ER group. Chi-square, however, revealed a significant difference (χ2 = 5.464, df = 1, n = 176, p =.019, Eta = .176) for bookstore visits."

Rodrigo 2014 (2)¶

Rodrigo, V., Greenberg, D., & Segal, D. (2014). Changes in reading habits by low literate adults through extensive reading. Reading in a Foreign Language, 26(1), 73-91. http://nflrc.hawaii.edu/rfl

q3 · i? · causal · r2

Follow-up Chi-square on library visits; the article reports the difference as statistically significant with "Eta = .215" but no standardized effect size in d, g, or r form, so no magnitude is coded. The groups already differed at baseline (78% vs. 59%, p = .008), which the authors note as a pre-treatment difference.

"However, 6 months after treatment, in the follow-up, the ER group appears to continue to visit a library more often (82% vs. 63%) while the no-ER group shows a decrease, and this difference is statistically significant (χ2 = 4.672, df = 1, n = 101, p = .031, Eta = .215)."

Discussion¶

Related Claims¶

• The ER group developed book-completion behavior after treatment, and the difference persisted at 6-month follow-up — related
• Low literate adults in an extensive reading intervention read more books than no-ER peers after treatment and at 6-month follow-up — related
• The language variable only partially affected reading habits: native speakers read and finished more books in some comparisons, with no differences on other variables — related
• Media print exposure did not differ between the ER and no-ER groups at any point, though both groups changed over time — related
