Here is the recap of this week’s expanding learning time (ELT) news:

U.S. Secretary of Education Arne Duncan visited the Orchard Gardens K-8 ELT School in Roxbury, MA, this week to highlight the USED’s Turnaround Arts Initiative. Turnaround Arts helps schools in the early-to-mid stages of school reform to use the arts to increase student engagement and improve the culture and climate of the school. Watch the Boston Herald report inside the school on YouTube.

As part of the city’s 2015 budget, Washington, D.C. Mayor Vincent Gray and D.C. Public Schools Chancellor Kaya Henderson want to dramatically expand a pilot program that allows low-performing schools in D.C. to expand their school days. Gray and Henderson want to allow up to 40 low-performing public schools — 21 elementary schools and every middle school — to expand their day for up to an additional hour every day.

Massachusetts’ Lawrence Public Schools are already showing early gains and kids are doing better academically after expanding their school year this year in the entire district’s elementary and middle schools. The percentage of students scoring proficient or higher on the math portion of the MCAS went up by double digits last year in third grade, fifth grade, eighth grade and 10th grade.
