{"abstract":"This research aimed to assess the effect of Math USAD (Umpisahan sa Addition hanggang Division) and its effects on the Mathematical Performance of Grade 7 students in Morong National High School. This study employed the experimental research method employing single group design with forty (40) Grade 7 students in Morong National high School using homogenous purposive sampling since the learners who belong to the heterogeneous group who falls under the category of Fairly Satisfactory and Did not meet expectations in their first and second quarterly grades participated in this study. Thus, the data were gathered using pretest-posttest design. Based on the statistical analysis, there is a significant difference between pretest and posttest scores (p-value < 0.05), indicating the positive impact of Math USAD on Mathematical Performance of the Grade 7 students. The study's conclusions were evaluated and discussed, and recommendations for additional research were made.","abstract_source":"original","authors":["Eula Marie Padlan","Liza Bonifacio","Mia Rose Ann Iway"],"date":"2023-08-31","doi":"10.5281/zenodo.8305383","id":1913,"issue":10,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"70e058b5c41e908c2884f8773b308289206ff101523631279de0927153ebfb07","schema":"scimatic-article/1","title":"Utilization of Math USAD (Umpisahan sa Addition hanggang Division) and its effects on Mathematical Performance of Grade 7 Students: An Action Research","volume":12}
