Supporting Multilingual Learners at Busan Foreign School: An Action Research Study

MS/HS ELL teacher Nate Kebbas Published in Fall Edition of EARCOS Triannual Journal

At Busan Foreign School (BFS), the diversity of our community is one of our greatest strengths. With students from more than 20 nationalities, BFS is proud to provide an inclusive learning environment where every child is supported in reaching their full potential. This year, Secondary ELL teacher Nathaniel Kebbas brought that mission into focus by conducting an action research study published in the EARCOS Triannual Journal (page 54) on how international schools in South Korea prepare teachers to support English Language Learners (ELLs).

 “I wanted this research to capture not just what schools are doing, but what teachers bring with them when it comes to supporting language learners.” Kebbas reflects

The study surveyed EARCOS member schools, evaluating six key areas including language policy, teacher training, school systems, and overall culture. On average, schools met about two-thirds of the benchmark, evidence of meaningful progress. At the same time, gaps emerged in areas such as regularly updating language policies, expanding targeted professional development, and ensuring strong communication and collaboration among staff.

“These findings tell us that international schools are on the right path,” Kebbas explains, “but they also show we need to be more intentional. A one-size-fits-all mentality simply doesn’t work for such a broad range of language learners.”

At BFS, Kebbas is part of a dedicated K–9 ELL team of three specialists, providing both inclusive classroom support and sheltered programs for students who need more targeted instruction. “What I appreciate at BFS is the balance,” Kebbas notes. “Our team approach ensures that students don’t feel isolated—they are learning alongside their peers, but they also have the support they need to succeed.”

The study highlights how schools can grow stronger by combining research with practice, and it underscores BFS’s ongoing commitment to building a culture where multilingual learners thrive.
