In the wake of the genocide,
Volunteers from the West can contribute several needed skills as teachers there. First, they bring their experiences in interactive educational settings. For some, this experience comes from their years as a student and for others like me, it comes also from tutoring and teaching experiences. Second, they bring expertise in specific areas. Many of the volunteers in my group have one or more post-secondary degrees and/or industry experience in a math or science related field. For a country in which only 5% of the population has a secondary degree, teachers with a deep understanding of such topics are great resources in helping Rwanda to achieve it's educational goals.
Another goal of the Rwandan government is to create a trilingual society (Kinyarwanda, French, and English). To do this, they are transitioning into an English language based education. Currently, most of their upper level math and science classes are taught in English. Native English speakers offer exposure to English that will help students improve upon their own English speaking abilities.
