Reading the full report provides a helpful overview and it’s clear that a lot of work went into conducting the pilot and evaluating these programs. Ever the data nerd, I read the report and then went right to the data provided in the appendices. As it was difficult to eyeball things from all the different pages presented, I’ve distilled it down and color coded the average ratings received (strongest ratings are in green; weakest ratings are in red) so that overall ratings can be readily viewed simultaneously.
Of the 42 items rated by teachers on the Materials Review subcommittee, Math Expressions was rated the highest on 26 items and lowest on just 1. Investigations was rated highest on only 13, and lowest on 14. enVisions was rated highest on a mere 2 and lowest on 26.
Broken down by ratings area (e.g., content, instruction, assessment, etc.) and grade level, Math Expressions is rated higher than Investigations 75% of the time:
Thanks for doing this – the color coding goes a long way toward telling the story. I noticed that the “Overall Mean” row in the top chart isn’t right – Investigations and enVision are swapped.
Thanks – this has now been corrected.
