In response to the Philippines low reading proficiency ranking based on the 2018 PISA results, the study titled WORDWISE: A SUPPLEMENT FOR ENHANCING LEVEL OF VOCABULARY OF GRADE 7 STUDENTS IN PEDRO GUEVARA MEMORIAL NATIONAL HIGH SCHOOL set out to assess the efficacy of a researcher-made vocabulary supplement in raising the vocabulary levels of Grade 7 students. For the purpose of tracking vocabulary growth independently, four groups of Grade 7 students were chosen using convenience sampling and an experimental design. When creating the intervention and research instruments, professional guidance was sought. The study tackled a number of important issues. It began by assessing the WordWise features usability, design, content, and degree of interactivity. Secondly, it evaluated the degree of vocabulary growth concerning usage, correlation, scope, and complexity. The study also looked at how well students performed on WordWise Exercises and the Screening Test Class Reading Record (STCRR). Students expressed great pleasure with the WordWise supplements design, usability, interactivity, and substance in their feedback. They commended its extensive content, broad vocabulary coverage, lucid explanations, and useful applications. Its aesthetically pleasing layout, readable fonts and colors, useful images, and logical organization all drew praise. Notable usability elements that were emphasized included progress tracking, easy navigation, unambiguous directions, and entertaining activities. The tools overall effectiveness in raising vocabulary levels was attributed to the interactive elements, which were found to be both enjoyable and helpful for vocabulary acquisition. Additionally, students showed mastery in relationship, depth, usage, and breadth as well as other areas of language application and knowledge. This shows that students vocabulary growth was significantly and diversely aided by the WordWise technology. Students also demonstrated strong performance on the WordWise Exercises and the STCRR, suggesting that the WordWise supplement had a beneficial effect on vocabulary and reading comprehension assignments. Nevertheless, statistical study failed to uncover any meaningful relationships between vocabulary expansion and WordWise features—Interactivity, Design, Content, and Usability. This is consistent with the null hypotheses HO1 and HO2, which propose, respectively, that there is no meaningful relationship between WordWise attributes and students results in the WordWise Exercises and STCRR. Higher scores on the STCRR compared to the WordWise Exercises, as indicated by the paired t-test, suggest a potential difference in assessment focus and skill evaluation between the two tasks. Despite the encouraging outcomes of the WordWise tool, further research is needed to explore the variables driving vocabulary development among Grade 7 students. As seen by the paired t-test, higher results on the STCRR relative to the WordWise Exercises point to a possible distinction in the assessment focus and skill evaluation between the two tasks. Even though the WordWise tool produced encouraging results, more investigation is required to determine the factors influencing vocabulary development in students in Grade 7.
