Interesting. Thanks for the report.

I agree with your concern about the representativity of the sample.

I was concerned that instruction for students with disabilities was not considered in the survey.

Also, I'm saddened that "Connecting Math Concepts" by McGraw Hill was not among the possible choices. Perhaps it would have been (or was) chosen very infrequently. However, it is a curriculum that is predicated on both good research and sage instructional principles.

My daughter’s former middle school switched to Illustrative Mathematics just as she started middle school. It was the most awful rubbish, perhaps the worst curriculum I’ve ever seen with the possible exception of TERC.

I wrote long critiques of it to the district, tried to enlist other parents in fighting it, but it was for naught.
