Welcome to Parsimony’s blog, where we help K-12 educators identify evidence based ways to maximize student outcomes.

This blog post is part of our What Works Clearinghouse review series. The What Works Clearinghouse (WWC) is an initiative by the Institute of Education Sciences (IES) which is the independent statistics, research, and evaluation arm of the United States Department of Education. WWC estimates the effectiveness of programs by evaluating the quality and quantity of evidence for that program.

This week’s blog post is about the evidence behind Odyssey® Math’s impact on students. Here’s the short version:

Odyssey® Math is a web-based program developed by Compass Learning® for mathematics instruction in grades K–8. The online program includes a mathematics curriculum and formative assessments designed to support differentiated and data-driven instruction.

The evidence for Odyssey® Math covers students in 4th grade through 8th grade.

The outcomes examined include: general mathematics achievement. Here’s what the evidence suggests about Odyssey® Math’s impact on each outcome:

  • General mathematics achievement: Positive impact (an average student would be expected to improve by 12 percentile points)

The studies looking into Odyssey® Math had student samples who were White and Black, and were English language learners, and received free & reduced price lunch.
