I’m excited to share my dissertation, where I explore how data-driven insights can identify the most effective instructional models for English Language Learners (ELLs) in various educational settings. In this research, I analyze the impact of self-contained and cotaught classrooms on ELL outcomes, offering practical solutions for educators seeking to optimize classroom strategies. Below is a brief overview, and you can access the full dissertation through the link. Happy Languaging!
Transforming ELL Education: A Data-Driven Approach for Better Outcomes
English Language Learners (ELLs) face unique challenges in U.S. public schools, including widening achievement gaps and higher dropout rates. My dissertation, A Quantitative Causal Comparison of State Standardized Test Scores in Cotaught and Self-Contained ELL Content Classes, uncovers critical insights into how classroom placement can significantly impact ELL academic success. By publishing my research online, I aim to share evidence-based strategies to help educators and policymakers transform ELL education.
Key Contributions to ELL Education
- Revolutionizing ELL Teaching Models: My study reveals the profound benefits of self-contained classrooms for ELLs. These settings, where instruction is tailored to students’ specific language needs, consistently outperform cotaught classrooms on standardized tests. This finding challenges traditional assumptions and highlights the need for a targeted approach to ELL education.
- Empowering ELL Learners: Self-contained classrooms create an inclusive, supportive environment where ELLs can confidently develop academic language skills and content knowledge. This model fosters better engagement and builds the foundation for long-term success.
- Rethinking Classroom Integration: While cotaught models promote integration with native English-speaking peers, they often lack the focused support that many ELLs require. My research advocates for a nuanced approach, blending the strengths of both models to optimize outcomes.
- Data-Driven Policy Recommendations: The findings provide actionable insights for educators, administrators, and policymakers. By investing in proven strategies like self-contained classrooms, schools can better allocate resources, close achievement gaps, and ensure ELLs graduate prepared for future success.
