Subclaims¶

q3 i? After treatment, only 7% of the ER group versus 31% of the no-ER group said they had never read a whole book, a highly significant difference. → Rodrigo 2014 q3 i? The book-completion difference remained significant 6 months after treatment. → 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 survey item on whether participants completed whole books, analyzed by Chi-square across the ER and no-ER groups; the article reports the difference as highly significant with "Eta = .309" but no standardized effect size in d, g, or r form, so no magnitude is coded. At baseline all 108 respondents said they normally finished books they started.

"Then only 7% of the ER group versus 31% of the no-ER group said they had never read a whole book. The difference between the two groups is highly significant (χ2 = 15.383, df = 1, n = 161, p = .000, Eta = .309) and shows change in reading behavior for the ER group."

Rodrigo 2014 (2)¶

q3 · i? · causal · r2

Six-month follow-up of the book-completion item; the group difference remained significant with "Eta = .323" (n = 104), but no standardized effect size is printed, so no magnitude is coded. The authors interpret this as the ER group learning to stick with a book until finished.

"However, it should be noted that this literate-like behavior remained fairly strong over time, (i.e., 6 months after treatment [χ2 = 10.883, df = 1, n = 104, p = .001, Eta = .323])."

Discussion¶

Related Claims¶

• 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
• The ER group showed more bookstore and library visiting than the no-ER group, with the library difference significant at follow-up — related
• Media print exposure did not differ between the ER and no-ER groups at any point, though both groups changed over time — related
