{"abstract":"This study investigated the effectiveness of mnemonic devices, spaced repetition, and brain training on memory recall among Senior High School STEM students in General Biology 1. A quasi-experimental design with pre-test and post-test was conducted at Saint Mary’s University, involving Grade 12 STEM students with average scores ranging from 88 to 91. Participants were grouped by the memory recall technique used. A frequency count determined differences in quiz scores before technique use, while a paired sample t-test assessed differences after technique use. The research found that students' performance levels significantly improved, shifting from predominantly low to a higher frequency in the medium to high levels. This indicates that mnemonic devices, spaced repetition, and brain training all led to notable improvements in quiz scores compared to pre-test results. Significant differences in quiz scores were observed before and after applying each technique, demonstrating their effectiveness in enhancing memory recall among participants.","abstract_source":"gemini_shortened","authors":["Carla Kirstein Lj Melegrito","Klythene Genosie Baclig","Kean Mari Balantac","Dianne Audrey Guzman","Kych Kyna Vidal","Lady Valen Charon DelaPeña","Kristel Joy Dapiawen"],"date":"2025-04-17","doi":"10.70838/pemj.350604","id":4899,"issue":6,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"8c6ad0a10bedf93b62ccd507b33c629f7d0b955ae71e7f6f1709f062820a9652","schema":"scimatic-article/1","title":"Effectiveness of Self-Paced Learning using Mnemonic Devices, Spaced Repetition, and Brain Training on Memory Recall of Senior High School STEM Students","volume":35}
