q2 · i? · review · r1

The white paper reports, citing LRRC (2015), that word recognition fluency combining accuracy and rate "significantly predicted reading comprehension of students in grades 1–3." No effect size is printed.

"Researchers at the Language and Reading Research Consortium (LRRC) found that that word recognition fluency—a measure that includes both accuracy and rate—significantly predicted reading comprehension of students in grades 1–3 (LRRC, 2015)."

q2 · i? · review · r1

The paper reports, citing LRRC (2015), a grade-level moderator: accuracy predicts comprehension more strongly for first- and second-graders, while for third-graders rate-inclusive fluency measures "predict reading scores better than accuracy scores alone."

"accuracy is a stronger predictor of reading comprehension for first- and second-graders, but for third-graders, measures of fluency that include rate predict reading scores better than accuracy scores alone (LRRC, 2015)."

Learner Variables¶

• Decoding — predictor: learners who differ on it differ in outcomes
