Here is Principle Four, related to this:
Principle Four: Teaching and Learning activities are planned and delivered in a way that reflects the importance of language in facilitating effective learning across and within each curriculum area.
a. In our bilingual context there is a clear understanding of the importance of developing listening, writing and speaking skills in English and Spanish and their key role in providing a framework for developing understanding and thinking skills across the curriculum in line with our Language Policies.
b. Language fluency plays a key role in providing a framework for developing understanding and thinking skills across the curriculum, and, as such, all teachers are aware of the need to provide strategies to develop students' fluency in the language of instruction.
c. Teachers understand the important of building academic vocabulary to support learning within their curriculum area and have in place effective strategies to teach this vocabulary. Students will have access to the critical vocabulary in Spanish as well as English.
