{"abstract":"This quasi-experimental study aimed at determining whether or not Trending Motivational Activities had an effect on the mathematics performance of students. Fifty-three Grade 7 students from each of two intact sections of Sara National High School were matched based on their pretest results and assigned to Trending Motivational Activities or traditional motivational activities through a toss coin for an eight-week intervention. Data were gathered using a 30-item multiple choice researcher-made pretest and posttest covering Basic Concepts and Terms in Geometry, Angle, Basic Constructions, Polygons, Triangles, Quadrilaterals, and Circles, along with an observation-checklist for teacher-observers. Mean and standard deviation were used for descriptive analysis, and a t-test for independent samples at 0.05 alpha was used for inferential analysis. Prior to the intervention, the mathematics performance of both groups was comparable and categorized as \"low\", with no significant difference in pretest scores. After the intervention, students in both groups improved from \"low\" to \"high\" and showed a significant difference in their performance. Nevertheless, there was no significant difference in the mean gain scores of the students in the two groups; students exposed to Trending Motivational Activities became more active and participative, and maintained their enthusiasm and interest in mathematics throughout the conduct of the study.","abstract_source":"gemini_shortened","authors":["Gretchen Abañera"],"date":"2022-08-16","doi":"10.5281/zenodo.6994920","id":505,"issue":8,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"039f3cdb57743df3f244fbf46612c94f6f4353ba3458bbac1470909884442bfb","schema":"scimatic-article/1","title":"Trending Motivational Activities and Mathematics Performance of Grade 7 Students","volume":3}
