Four Key Focus Areas for Improved Student Outcomes

District leaders, principals, and teachers agree that SEAL works in their schools and classrooms. How do we do it? By focusing on these four areas for student success, we create learning environments that are at once welcoming and challenging.

Oral Language

Oral Language practice with sophisticated, academic concepts is foundational to learning and language development, especially for MLs. SEAL practices and strategies foster rich, content-based dialogue among students.

Biliteracy Development

SEAL supports students' home language development and biliteracy, helping them master multiple languages while simultaneously deepening their content learning.

Student Engagement 

SEAL’s approach cultivates student engagement. The learning is inquiry-based, active and joyful. Instruction is culturally and linguistically responsive and builds on students' interests and experiences. 

Content Learning 

SEAL’s approach supports language and literacy development within grade level content learning, including science and social studies, to increase students’ access to the full curriculum in rich and rigorous ways.

Putting SEAL to the Test: Findings from a Multi-year Evaluation

Between 2015 and 2019, Loyola Marymount University's Center for Equity for English Learners (CEEL), alongside the Wexford Institute, studied the SEAL model across 67 schools in 12 districts. The results? At SEAL schools there were improvements in (1) teaching practices, (2) student engagement, and (3) language and academic development among English Learners and Dual Language Learners. These findings affirm that the SEAL model can be successfully scaled up to benefit students across California and, eventually, the country.

Student Success and Outcomes

Early learners with minimally developed language skills are at risk of falling behind in English, academics, and even their home language. SEAL focuses on strengthening students’ language, biliteracy, engagement, and content learning—and the results speak for themselves.
