Mike Petrilli talks with Education Next about the challenges of teaching high-achieving and low-achieving kids in the same classroom, and about one school in Montgomery County, Maryland, which is using a blend of ability grouping and differentiated instruction with great success.

For more on this topic, see “All Together Now? Educating high and low achievers in the same classroom,” by Mike Petrilli, which appears in the Winter 2010 issue of Education Next.
