The Iowa Reading Research Center’s Effective Fluency Instruction for Fourth Graders study showed an alternative approach to improving students’ reading fluency was effective, while both approaches studied resulted in exceptional growth.

During the Spring of 2018, students at 21 elementary schools across Iowa were randomly assigned to either Repeated Reading or Varied Practice Reading for the study.

Students in the Repeated Reading group read one passage three times in succession. This has been the most common approach to improving reading fluency. However, this approach can lead students to read in ways that are not authentic to how skilled readers approach texts. For example, some teachers have directed students both in class and for home reading to read each page of a book three times. There is no evidence that this approach is effective for book reading, however. 

For the Varied Practice group featuring the alternative approach, students read three different passages, one time each. The passages used similar words, which is referred to as “word overlap.” Students had the chance to practice many of the words in a passage several times, but did so while seeing them in a different order and used in different contexts across the second and third passages of the set.

A total of 827 fourth-grade students practiced 3 to 4 times per week for 20 minutes per session, for an average of 26 sessions. They read with a partner, and helped each other review any missed words.

The study results show the Varied Practice group statistically significantly outperformed the Repeated Reading group. In fact, Varied Practice achieved slightly more than an extra week’s worth of improvement in reading fluency over Repeated Reading. Students in both groups showed growth near the 90th percentile, which would be considered very ambitious growth.

These findings are encouraging, study authors say, and indicate that reading fluency practice through means other than Repeated Reading may be beneficial. However, more research over multiple studies would need to show improvement to establish an evidence base for Varied Practice.

Varied Practice Passage Sets Available for Teachers via eLearning

The Iowa Reading Research Center has developed a Varied Practice Reading instructional method to facilitate use of Varied Practice Reading passage sets in the classroom. This instructional method is available to teachers through our eLearning Varied Practice Reading module. Those who complete the module will receive access to digital versions of the passage sets. See our eLearning page for more information.
