For the past two years, eighth graders at Lincoln Middle School have been participating in the STEMester of Service program, which uses the science, math, and language arts curricula to help students improve the environment. More than 70% of Lincoln students receive free and reduced-price lunch, and the school is diverse because it hosts the district's newcomer and international student program. A structured semester of service learning provides teacher preparation and support. Students work across disciplines to identify and contribute to solutions for a local environmental problem. Through the STEMester of Service, students, teachers, and community partners implement high-quality service learning not only to "green" their schools and communities but also to increase student engagement and achievement. Teachers encourage students' interest in their communities by giving them a voice and teaching them how they can make a difference. And as a result of their study and service, students develop their leadership and academic skills.
