The Impact of Classworks® Individualized Learning Math Instruction as an Academic Intervention for Second Grade

This study examined the impact of Classworks® Individualized Learning math instruction on second-grade students performing below the 25th percentile in math. The research, conducted during the 2021-2022 school year, involved 1,367 students from 45 schools across seven districts. A quasi-experimental design compared 941 students who had any use of Classworks (treatment group) with 426 students who did not (comparison group). Students in both the treatment and comparison groups completed the Classworks Math Universal Screener assessments at the beginning and end of the school year. The study employed linear modeling with adjustments for clustering, baseline achievement, and district fixed effects. Results showed that Classworks users scored an average of 5.17 points higher on the spring math assessment compared to non-users, with an effect size of 0.13. Treatment group students engaged with the program for an average of 11 minutes per week over 30 instructional weeks. These findings suggest that Classworks Individualized Learning math instruction has a positive impact on the math performance for struggling second-grade students, even with modest time investment. Educators may consider implementing such personalized, technology-based interventions to support students performing below grade level in mathematics. Future research could explore the program's long-term effects and its impact on different student subgroups. The study includes tables presenting baseline equivalence statistics and model-based results, along with references supporting the methodology and context of the research.
