{"abstract":"This study explores the effectiveness of multimedia teaching resources in improving the cognitive and technical skills of Grade 11 students enrolled in the Food and Beverage Services (FBS) strand at General Mariano Alvarez Technical High School. Anchored in Richard Mayer’s Multimedia Learning Theory, the research connects theoretical insights with classroom application through the use of videos and interactive instructional materials. It evaluates instructional videos in enhancing student learning and examines the relationship between cognitive and technical competencies. Using a pre-experimental design, the study involved two groups from the same specialization and schedule. Cognitive skills were assessed using pre-tests and post-tests based on Bloom’s Taxonomy, while technical skills were evaluated using performance rubrics in tasks like food service and customer assistance. A pre-test was administered to gauge prior knowledge. Instructional videos were shared via group chat, allowing students to learn at their own pace. A post-test followed to measure learning outcomes. The findings revealed notable improvement in both cognitive and technical skills among students who received multimedia-enhanced instruction. There was also a correlation between students’ perceptions of multimedia instructional materials and academic performance. These results underscore the value of multimedia as an effective educational tool for improving Technical Vocational Livelihood instruction.","abstract_source":"original","authors":["Jennifer Castillo"],"date":"2025-07-16","doi":"10.70838/pemj.420501","id":5790,"issue":5,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"ba32dd43b9f1fd8aae02915fffe997f62b5799ff82db6dbf6c7866f117e15aca","schema":"scimatic-article/1","title":"Multimedia Instructional Materials for an Improved Cognitive and Technical Skills in Food and Beverage Services","volume":42}
