Welcome to the classroom of Jill Sontag and her 19 young bilingual collaborators. Join them as they simultaneously explore the world of insects and the world of language. These curious and energetic second graders are easily drawn into the realm of bugs. Encouraging them to speak in Spanish, however, is a bit more complicated. Jill uses her professional judgment to make choices about when and how to reinforce second language acquisition and literacy in Spanish in this two-way bilingual immersion classroom. Creativity and humor are cornerstones of her pedagogical style and are maximized throughout this inquiry-based curriculum. Content and literacy are authentically interwoven as the teacher skillfully promotes bilingualism.
