During the Spanish period, English and Spanish were the medium of instruction in schools. This means that classes were taught in both English and Spanish languages.

This bilingual approach helped students like Lucy to gradually transition to English while ensuring they didn't fall behind in their learning. In Lucy's case, within two years, she was mostly receiving instruction in English.
