Optimizing Young EFL Learners’ Phonics Instruction Based on the Comprehensible Input and Output Hypotheses: Explaining the Decoding-Spelling Imbalance in Primary English Classrooms
TOTAL VIEWS: 635
Abstract
Phonics instruction bears the dual tasks of decoding and spelling in the early development of reading and writing ability of young English as a foreign language (EFL) learners. However, in phonics instruction for young learners, some students show the problem of decoding-spelling imbalance, which may hinder the coordinated development of early English literacy. The existing research on phonics instruction mainly focuses on systematic skill training, decoding development, or participation in classroom activities. Few studies have examined the value of Krashen’s Comprehensible Input Hypothesis and Swain’s Comprehensible Output Hypothesis, and there is still insufficient discussion on the development of phonics instruction for young learners. This study adopts a qualitative literature review to synthesize relevant theories and teaching research on input, output, phonics instruction, decoding, and spelling. It examines how input- and output-related factors lead to decoding-spelling imbalance, and discusses the corresponding teaching optimization principles. The reviewed literature shows that unsystematic and non-cumulative Grapheme-Phoneme Correspondence (GPC) input may provide limited support for spelling development, and the lack of independent, spelling-oriented output opportunities may limit learners’ active retrieval and consolidation of orthographic knowledge. By integrating the views of comprehensible input and comprehensible output, this study provides a theoretical framework for explaining the imbalance and puts forward research-based principles to formulate a more systematic and balanced phonics instruction for young elementary EFL learners.
