ASU Professor Jeff MacSwan notes problems with data used in a new Arizona Department of Education report, The Effects of Bilingual Education Programs and Structured English Immersion Programs on Student Achievement: A Large-Scale Comparison.

Two other essays in response were published in The Arizona Republic, one by Johanna Haver, "Data 'Poison' Just When Others Use It," and one by Beth Swadener, "English Immersion Robbing Students."
