Phonological awareness is a critical skill that children must master during the early foundations of literacy. It is considered a highly accurate predictor of a child’s success in learning to read. However, at the expected age, there are cases in which children have not developed phonological awareness that consequently result in poor reading skills. This case study sought to determine the alphabet knowledge of two seven-year-old children and address their difficulties in phonological awareness through the alphabetic code. The researchers conducted ten sessions of phonological interventions to  children with identified language learning difficulties in reading. The data analysis and collection process included curriculum document reviews, diagnostic assessments, phonological interventions, and evaluation. Diagnostic results indicated that the children have difficulties in letter recognition of Consonant-Vowel-Consonant (CVC) patterns, blending, and segmentation of phonemes. However, anchoring on the principles of learning-by-doing delivered through oral-situational as a core language approach, the interventions in this case study were found effective for phonics instruction. The audio-lingual method and the total physical response in learning phonics, or letter sounds, activated children’s basic phonological skills. Repetition, drilling, memorisation and performing language or vocabulary concepts using physical movement to react to verbal input can lessen the phonological difficulties of children. In light of the current global situation, no previous studies have applied a case study utilizing both audiolingualism and total physical response to address the phonological issues of non-readers. Hence, this study offers scientific and pedagogical implications.
