The purpose of this study is to investigate the effects of a tier 2 phonics instruction for students
with spelling difficulties. After eight weeks of tier 1 intervention, six students with spelling
difficulties were identified as students in need of tier 2 intervention. Tier 2 phonics intervention
comprised 10 sessions delivered across five weeks. All the lessons were designed to instruct the
reading and spelling of final consonants. After the intervention, all six participants improved their
phonemic awareness, word recognition, and spelling skills based on CBA results. The t test results
also showed that students’ improvement on standardized test were statistically significant in the areas
of phonemic awareness, word recognition, and spelling. These results imply that Hangul phonics
instruction was effective as a tier 2 intervention for students with spelling difficulties. Authors
suggest that Hangul phonics need to be implemented in elementary schools as part of the regular
curriculum, especially for students who need extra help. Concerns regarding students from a
multicultural background and implements of tier model in the school settings were discussed.
