I just took a skim through the material. The only objectionable thing was couching it in heavily racial or equitable terms, but the bulk of the work is really just trying to look for opportunities to improve pedagogy. The content itself is pretty vanilla and is discussing methods of pedagogy that are pretty old (at first glance it does not seem meaningfully different from the Montessori method and other approaches like “couching math in everyday examples” is an old idea).
The difference is in the results. At the end of the day, children taught by the Montessori method were proficient in reading, writing and math. Today proficiency levels are plunging at the same time that the focus on "education" is being shifted heavily towards "diversity and equity".
