The Growing Evidence Against separating English Learners: rethinking Educational Practices for Better Outcomes
For decades, a common practise in American schools has been to separate English Learners (ELs) for dedicated instruction. However,a growing body of rigorous research is challenging this default approach,suggesting that segregating ELs may not only fail to deliver academic benefits for most students,but can actively hinder their long-term success. Recent studies from New York University (NYU) Steinhardt, published in leading education journals American Education Research Journal (AERJ) and Psychological Science, provide compelling evidence for a shift towards more inclusive educational models.
Challenging the Status Quo: Findings from Recent Research
The research, led by Professors Michael Kieffer and Rachel Black, utilizes both randomized controlled trials and large-scale data analysis to paint a nuanced picture of EL education. Professor Kieffer’s team directly examined the impact of homogenous versus heterogeneous grouping in elementary schools. 84 fourth and fifth-grade ELs were randomly assigned to either groups comprised solely of els or mixed groups with English-proficient peers. Over a 12-week period, both groups received the same curriculum delivered by the same teachers. The results? No significant difference in overall academic outcomes for the average student.
However, the study revealed a critical nuance: heterogeneous groups appeared to benefit students with stronger English language skills, fostering richer classroom discourse through more open-ended questioning by teachers. Conversely, students at earlier stages of English acquisition showed slight gains in homogenous settings, likely due to more targeted language instruction. This suggests that while some strategic homogenous grouping may be appropriate for initial language support,it shouldn’t be the default. As Kieffer emphasizes, “grouping English learners together should be done sparingly and strategically.”
The second study, focusing on high school students in New York City, analyzed data from over 31,000 ELs tracked over six years. Researchers categorized students based on their years learning English (newcomer, developing, and long-term ELs) and examined the impact of ”EL concentration” – the percentage of ELs in their courses - on graduation and college enrollment rates. The findings were stark.
Irrespective of prior English proficiency or school demographics,higher concentrations of ELs in courses were consistently linked to:
* A 10-15% decrease in four-year graduation rates.
* A 6-11% decrease in six-year graduation rates.
* A 12-13% decrease in immediate college enrollment.
* A 9-13% decrease in college enrollment within 2.5 years of graduation.
These are not marginal differences.They represent significant barriers to opportunity for a vulnerable student population. This data strongly suggests that isolating ELs, even unintentionally through course tracking, can create a self-fulfilling prophecy of lower academic achievement.
Why Separation Frequently enough Fails: A Deeper Look
These findings align with a growing understanding of how language acquisition works. Effective language learning isn’t simply about receiving targeted instruction; it’s about meaningful interaction with language in authentic contexts. Heterogeneous classrooms provide precisely that – opportunities for ELs to engage with native speakers, negotiate meaning, and develop the communicative competence necessary for success.
Furthermore, separating ELs can inadvertently limit their access to challenging coursework and enriching extracurricular activities. It can also contribute to feelings of isolation and marginalization, hindering their social-emotional growth and overall integration into the school community. As Professor Black powerfully states, ”English learners have a right to be integrated into the life of their school, and an important part of that experience is taking courses with English-proficient peers.”
Moving Forward: Towards Inclusive EL Education
The implications of this research are clear: schools need to critically re-evaluate their practices regarding EL placement and instruction. This isn’t about abandoning support for ELs; it’s about providing that support within inclusive settings.
Here are key steps schools can take:
* Prioritize Integrated Instruction: Focus on providing high-quality language support within mainstream classrooms, rather than pulling ELs out for separate instruction whenever possible.
* Professional Development for Teachers: equip all teachers with the knowledge and skills to effectively support ELs in their classrooms, including strategies for differentiated instruction, scaffolding, and culturally responsive teaching.
* Strategic Homogenous Grouping (When Appropriate): Reserve homogenous grouping for short-term, targeted interventions for students at the earliest stages of English acquisition.
* Monitor EL Concentration in Courses: Actively work to avoid creating “EL tracks” where students are disproportionately concentrated in courses with other
