The Newton Free Library will again offer its hugely popular Girls Who Code after-school program for girls in Grades 6-12 on Friday afternoons 4-6PM during the 2016-17 school year.  Can you volunteer 2 hours per week as an instructor using the Girls Who Code computer-science curriculum?  It’s best if you’re proficient in programming languages, with intermediate knowledge of data structures and algorithms.  Perhaps you’re a current or former software developer or a current undergraduate/graduate student in computer science.  The most successful volunteer GWC instructors have experience teaching or working with youth — as teaching assistants, camp counselors, or tutors — although this is not required. To express interest or get more information, email teens@newtonfreelibrary.net.  Make a huge impact — in two hours per week over the school year.
