In kindergarten through 5th grade classrooms at Allen Jay Elementary School, students learn subjects like reading, math, and science in English, and in Urdu. The school, in High Point, N.C., offers dual-language immersion programs in Urdu and Spanish, reflecting the two most commonly spoken world languages in the local community. The programs follow a 50/50 model: Half of the day’s lessons are taught in English, the other half in either Urdu or Spanish. A teacher may be speaking in English, but a student may initially respond in Urdu if the answer is easier to first grasp in that language, or vice versa.
