ABSTRACT
The purpose of this study is to determine the effectiveness of project BLOC (Blending Letters through Mock calls) as a reading intervention in improving the reading word, particularly in initial and final consonant blends, for Grade 4 pupils of Lepanto Elementary School-Main in the Quezon District, School Year 2022-2023. The researchers used a one-group pre-test-post-test research design, with universal sampling of 22 Grade 4 pupils. Data were analyzed using mean scores and standard deviation to measure improvement, paired samples t-test to assess the significance of the results, and ETA-squared to evaluate the effect of the intervention. The findings of the study revealed that the project BLOC has a substantial impact on pupils’ reading ability, particularly on mastering the initial and final consonant blends. It is therefore recommended as a supplemental reading intervention to support early literacy development among elementary pupils.
