||Ryu, Do Hyung. (2018). A study of English word combinations and chunking: Application of the block concept. The Linguistic Association of Korea Journal, 26(2), 229-247. There is agreement that many word combinations are multiword units stored in long-term memory and retrieved as chunks. There is also increasing evidence that these formulaic language units are integral to first and second language acquisition. This is based on the view of chunking in the cognitive process, which can be utilized to overcome the limitations of working memory and increase its capacity. This study suggests that the chunking process should be the core basis of the learning and teaching of English in classrooms. The present study describes the -chunking process, word combinations, and the block concept of computer languages, based on block-based coding. A block puzzle activity was developed to use chunking with word combinations, an approach applied from the concept of block coding. The purpose of this study is to investigate the possibility and effectiveness of facilitating memorization of word combinations by a block puzzle activity based on the chunking process. The experiment results indicate that students recalled expressions of word combinations better. The findings have implications for EFL teaching and activity design purposes.
