This research analyzes the challenges teachers face in enhancing early literacy development among elementary school students within the context of deep learning pedagogy, focusing on a case study of letter recognition difficulties. Conducted at SD Negeri 3 Tempur, this qualitative case study examines a first-grade student who demonstrates an atypical literacy profile: the ability to "read" words with visual-picture support and copy written letters accurately, yet significant struggles with abstract letter recognition and differentiation. Through comprehensive observation and assessment, the study explores the cognitive, social-emotional, and psychological developmental dynamics of this learning pattern. Findings reveal that the student exhibits stronger dependence on visual-semantic processing pathways rather than phonological-alphabetic routes, experiencing particular difficulties with mirror-image letters and lacking phonological awareness development. The research identifies that deep learning approaches emphasizing symbolic processing without multimodal support may exacerbate early literacy gaps for children with non-typical literacy profiles. Based on Piaget's and Vygotsky's developmental theories, along with Dual Coding Theory, this study recommends comprehensive multi-component interventions including explicit phonological awareness instruction, multisensory letter recognition methods, individualized scaffolding, and close collaboration among teachers, parents, and professional specialists to support inclusive literacy development.
