What best describes Mr. Padillo's bilingual content approach during his lesson?

The preview-review approach is characterized by introducing students to content in both their native language and the target language, allowing them to build on prior knowledge and reinforce learning. This method often involves presenting a lesson with an overview or preview in the native language before delving into the target language, thereby creating a supportive bridge for ELL students to understand and engage with the material.

In the context of Mr. Padillo's lesson, if he uses strategies that allow students to first preview the subject matter in a language they are comfortable with, followed by a review in the target language, this would effectively empower the students. This process not only strengthens comprehension but also helps students connect new information with their existing knowledge, enhancing overall understanding and retention.

The other options represent different methodologies that may not align with the described approach. For example, while the immersion approach involves total exposure to the target language without using the native language, the sheltered instruction approach focuses on making content more accessible within the target language itself. The balanced literacy approach emphasizes reading and writing skills within a comprehensive framework but doesn't specifically target bilingual content adaptation. Understanding these methodologies clarifies why the preview-review approach is the most fitting description of Mr. Padillo's bilingual content approach.
