Summer Achievement Gap

Research suggests that nearly all students lose a month or more of skills and knowledge over the summer break. However, not all kids are affected equally. Middle-class children who make trips to the library, travel and take classes, experience some slide in math but little in reading. Low-income students lose math abilities like their middle class counterparts. In addition, though, poor kids can lose between one and two months in reading achievement.
Karim Abouelnaga  who co-founded Practice Makes Perfect (PMP) in 2011, has  a comprehensive summer education program to help close this gap. The core tenet of the program (which runs from Monday-Friday 9am-4pm, early July-Mid August) is that students teach each other. Two struggling students in second grade through eighth grade are paired with academically stronger students four years older. Three times a day, a Practice Makes Perfect teacher, usually a college student interested in education, gives a 15-minute lesson in basic skills associated with math, vocabulary, spelling or writing. Then the students and their mentors get to work completing an exercise using the skills the teacher has just taught. Lessons are broken up by meals, playtime, read-alouds, classes in entrepreneurship and trips to a nearby park.
