Abstract

The Department of Education (DepEd) in the Philippines emphasized the importance of foundational literacy skills in its K to 12 Curriculum, highlighting the need for phonics and phonological awareness in early education. Research on the effectiveness of using tangible aids like the CVC (Consonant-Vowel-Consonant) sound box technique in classroom settings was lacking. Studies showed that CVC word strategies and word box instruction were effective in improving students' vocabulary and basic literacy skills. For at-risk urban first graders, word box intervention led to increased acquisition of CVC words, with some participants demonstrating maintenance and generalization of skills (Aller-Morgan et al., 2021). The use of CVC word game strategies significantly increased vocabulary mastery among second-grade students, as evidenced by improved posttest scores (Hamzah et al., 2020). Structured phonological awareness interventions, particularly sound boxes, were effective in developing early literacy skills in preschool children. Children who received sound box instruction demonstrated enhanced phoneme segmentation performance, maintained these skills after the intervention, and showed some ability to generalize to untaught words (Durst & Joseph, 2020; Durst, 2020) The study evaluated the CVC Sound Box for teaching vocabulary words among 297 Grade 1 pupils at Maligaya Elementary School. Grade 1 sections were selected through simple random sampling. The result shows improved vocabulary performance among Grade 1 pupils, with 78% reaching a high-proficiency level and a composite weighted mean of 13.26. The Wilcoxon signed-rank test was reported as significant. Schools, teachers, parents, learners, and future researchers may examine causes of English reading difficulty and appropriate vocabulary interventions. The CVC Sound Box findings require fuller reporting of baseline performance, intervention procedures, and inferential statistics before effectiveness and retention can be assessed.
