{"abstract":"This study evaluated the perceived effectiveness and suitability of word problems as a tool for enhancing literacy and numeracy among elementary pupils in District VII of Malaybalay City Division during SY 2023–2024. Using a descriptive–correlational design and complete enumeration of 109 public elementary mathematics teachers, the research employed a researcher-made questionnaire validated by experts and tested for reliability. Data were analyzed through descriptive statistics and Pearson's r correlation. Findings showed that teachers rated word problems as generally effective (M = 4.01) and suitable (M = 3.98) for assessing both skills. No statistically significant relationships were found between respondents' demographic characteristics (age, sex, educational attainment, position, and length of service) and their perceptions of effectiveness. The results affirm the pedagogical value of integrating word problems to address literacy–numeracy competencies and recommend further qualitative studies to explore instructional improvements.","abstract_source":"original","authors":["Mechell Velasco","Edna Curayag"],"date":"2025-12-15","doi":"10.70838/pemj.500502","id":6881,"issue":5,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"a476d53b7c0f48f1a4ce864550670d5d78eaca93e6f2f38fcf0bacb89537af3f","schema":"scimatic-article/1","title":"An Evaluation Survey of Effectiveness and Suitability of Word Problems: A Literacy–Numeracy Tool","volume":50}
