{"abstract":"This quasi-experimental research was conducted to find out the effects of game-based and project-based approaches on Grade 10 learners’ performance in biology of Ramon Avanceña National High School, Iloilo City. Purposive sampling design was used and researcher-made instrument for pre-test and post-test on learners’ performance was also utilized in gathering data. It was found out that the grade 10 learners’ performance in biology before they were exposed to game and project-based approaches was fairly satisfactory. There was no significant difference in the pre-test scores of the group of learners in the game-based and project-based approaches. The Grade 10 learners’ performance in biology after they were exposed to game-based and project-based approaches was very satisfactory. There was significant difference in the pre-test and post-test scores of learners in the game-based and project-based approaches. There was no significant difference in the post-test scores of learners in the game-based and project-based approaches.","abstract_source":"original","authors":["Kevin Jurada"],"date":"2024-02-20","doi":"10.5281/zenodo.10681856","id":2550,"issue":3,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"7966d14a31721403604256e515594d6c268be37a2deb2bb5f9b63705d1082b77","schema":"scimatic-article/1","title":"Game-Based and Project-Based Approaches: Their Effects on Grade 10 Learners’ Performance in Biology","volume":17}
