The public school population in Minnesota, as in many other states, is becoming more diverse by race and ethnicity. But the teacher workforce? Not so much. About one-third of Minnesota students are non-white, compared with roughly 5 percent of teachers, as Faiza Mahamud and MaryJo Webster report for the Star Tribune newspaper. That’s a growing problem for educators and policymakers looking to give more students the opportunity to learn from someone who looks like them — a benefit researchers say can improve academic achievement, self esteem, and other factors in student success. Mahamud, who covers the Twin Cities’ public schools, spent time talking with students and families about what they’re looking for in classroom teachers, and how a lack of diversity can hurt family engagement, especially among newer immigrant families. Webster, the newspaper’s data editor, shares the ins and outs of finding — and crunching — statistics on teacher diversity, as well as some lessons learned from the project.
