PROJECT SOLVE (STUDENT OUTCOMES IN LEARNING VOLUME EXCELLENT): STRENGTHENING STUDENTS' ABILITY TO CONVERT UNITS OF VOLUME

The purpose of this study was to determine the effectiveness of the Project SOLVE (Student Outcomes in Learning Volume Excellent) strategy in enhancing the ability of Grade 7 students to convert volume units. Twenty-eight students from Sampao Integrated School were purposively selected to participate in a pre-experimental one-group pre-test and post-test design. The intervention lasted one month and involved a systematic procedure that included a pre-test, implementation of the Project SOLVE strategy, and a post-test using the same assessment tool. Results revealed a substantial improvement in performance, with the mean score increasing from 49% on the pre-test to 73% on the post-test. A paired-samples t-test indicated a statistically significant difference between pre- and post-test scores, t (27) = 6.91, p < .001, d = 1.31, suggesting a very large effect size. These findings demonstrate the effectiveness of Project SOLVE in improving students’ skills in volume conversion. Although some students reported difficulty during the evaluation phase of the intervention, qualitative data from interviews supported the quantitative findings by highlighting improvements in note-taking habits, motivation, and conceptual understanding. Overall, the study suggests that Project SOLVE is a promising strategy for strengthening students' mathematical competency in volume conversions.
