{"abstract":"This study determined the effects of algebra tiles on the academic performance of Grade 7 students in operations of integers and polynomials at Gil Montilla National High School-Camindangan Extension during the 2023-2024 academic year. Data was gathered using a standardized questionnaire based on the Enhanced Regional Unified Numeracy Test (ERUNT) for integers and self-learning modules for polynomials. Eighty participants were divided into a control group (40 students) and an experimental group (40 students). For the control group, the pre-test mean for integer operations was 20.20, increasing to a post-test mean of 26.38. For polynomial operations, the pre-test mean was 2.40, increasing to 7.83. For the experimental group, the pre-test mean for integer operations was 19.17 (nearly proficient), increasing to 27.78 (nearly proficient). For polynomial operations, the pre-test mean was 2.37 (not proficient), increasing to 9.70 (low proficient). The Wilcoxon Signed Ranks Test at a 0.05 significance level showed a computed value of -5.518 and a p-value of","abstract_source":"gemini_shortened","authors":["John Mark Peñafiel","Sharon Apohen"],"date":"2025-01-15","doi":"10.5281/zenodo.14652507","id":4356,"issue":9,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"2ce06cbb1e444caf5f0c58d2bb41caabfe2468cb5a5bb694fb3f13e46068e8c5","schema":"scimatic-article/1","title":"The Effect of Algebra Tiles in the Operations of Integers and Polynomials to the Academic Performance of Grade 7 Students","volume":30}
