The results were promising, according to a paper that was made public in October 2024. Half of the remedial students in the mixed class passed the ninth grade algebra course and moved on to geometry with their classmates. The other half still had to retake algebra in 10th grade, which is when they would have taken it anyway, but their test scores in 11th grade were higher than similar students who had learned math in a separate remedial classroom in ninth grade. Eleventh grade math achievement for remedial students who had taken ninth grade algebra was so much higher that the difference was equivalent to an extra year’s worth of math, according to the researchers.
