In a preschool class at Gardner Academy, a public elementary school near downtown San Jose, teacher Rosemary Zavala sketched a tree as she fired off questions about what plants need to grow. “¿Qué necesitan las plantas?” she asked her 4-year-old charges in Spanish.
“Las flores toman agua” was the exuberant answer from one girl, who said that flowers drink water. A boy answered in English: “I saw a tree in my yard.”
The next day, Ms. Zavala’s questions about plants would continue—but in English.
