{"abstract":"The Number Tower is a game intended to improve the performance of Grade 8 students at J.P. Laurel High School for S.Y. 2024-2025 relative to the addition and subtraction of integers. The study used quasi-experimental and one-group pretest-posttest as a research design. The researchers employ a non-probability sampling technique specifically purposive sampling. The study utilized the multiple-choice questionnaire for the pre-test, implemented The Number Tower Game for intervention, and conducted the post-test and interview guide afterward. The results of the pre-test and post-test show an increase in students' performance from FS (Fairly Satisfactory) to S (Satisfactory) after the utilization of the game. The result of the t-test revealed that there is a significant difference between the pretest and posttest scores of the 25 students after the utilization of the game. This means that the utilization of The Number Tower is effective in improving the level of performance of the least performing students in the addition and subtraction of integers.","abstract_source":"original","authors":["Jeann Guan","Maricar Dedase","Kelvin Carl Fulay","Jan Angelo Morata"],"date":"2025-03-26","doi":"10.70838/pemj.340405","id":4758,"issue":4,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"1f9745ab7ceee998c3d0ed13ecf10105596aec56d77fb1e4f85865a50ca55c0b","schema":"scimatic-article/1","title":"Enhancing the Mathematics Performance Level of Grade 8 Students through The Number Tower: A Game-Based Intervention in Addition and Subtraction of Integers","volume":34}
