q2 · i? · causal · r1

Platform-level manipulation conducted with ReadWorks for users in the target district: the audio default was changed so teachers no longer had to actively enable it but could disable it. The report calls this its experimental study of audio supports and concludes that when audio was available to more students, more students used it.

"This change in the default setting resulted in an increase in audio support availability from 72 percent to 99 percent of assignments. More students also made use of the feature, with the proportion of students who played audio in any of their assignments rising from 68 percent to 84 percent."
