{"abstract":"The present study aims to research and develop recommendations for improving the academic performance of Grade 11 students in a hybrid flexible modality. This was implemented by creating a self-made instrument, along with themed stores using coin counters from the incentives earned in the class, which was tested using a sample of 50 Grade 11 students from the Morong National High School. The results of this investigation revealed the effectiveness of themed stores using coin counters to not only improve students learning, but also the student’s ability retention, critical thinking, and time management. The themed stores using coin counters created interest in the students and kept them focused on improving themselves and their learning. As a result, it is recommended that educators and policymakers keep using the themed stores through the coin counters incentive system to enhance student learning and engagement.","abstract_source":"original","authors":["Florabel Hilario"],"date":"2023-05-16","doi":"10.5281/zenodo.7941915","id":1272,"issue":9,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"3f237edbefef954e08f28f8223aa55e601c86c76e10ccd1e2cb27fd3ae0500ea","schema":"scimatic-article/1","title":"Using Coin Counters in Themed Stores: Way of Improving Mathematics Performance","volume":8}
