Researchers analyzed state assessment scores from spring 2019 and spring 2021 in a large urban district where students experienced remote learning for the majority of the 2020–2021 school year. The study compared achievement growth on the state assessment for students who consistently completed three or more Zearn digital lessons each week during the disrupted 2020–2021 school year to students who did not consistently use Zearn. While this research study does not have a randomized control and differences between student groups cannot be fully ruled out, demographics were similar across all available measures.
In the context of district-wide declines, consistent Zearn usage resulted in score growth for students at every level of math proficiency.
Consistent Zearn usage dramatically reduced learning loss in district where learning was primarily remote during the 2020–2021 school year.
Across two disrupted school years when no students in the district reached the expected state two-year benchmark growth, consistent Zearn usage helped to mitigate pandemic learning loss. For students who met proficiency in 2019, scoring at Level 3, Zearn usage resulted in almost a year of learning gains, while students who did not use Zearn fell behind 0.7 years of learning over the course of two years.
