This study investigates the effectiveness of Nurturing Engagement and Lifelong Learning through Audio-visual (NELLA) as Supplementary Materials in Enhancing the Academic Performance of Grade 11 Students in Food and Beverage Services. Using a quasi-experimental design, ninety-six participants were divided into an experimental and comparison group using a match pairing method based on pretest scores. The experimental group received Nurturing Engagement and Lifelong Learning through Audio-visual (NELLA) interventions, while the comparison group followed the standard curriculum. Formative and post-test results revealed significant improvement in the understanding and learning outcomes of students using Nurturing Engagement and Lifelong Learning through Audio-visual (NELLA) compared to the comparison group. This suggests that Nurturing Engagement and Lifelong Learning through Audio-visual (NELLA), potentially through increased engagement, targeted instruction, and self-paced learning, maybe a valuable pedagogical tool for enhancing knowledge retention and comprehension in the Food and Beverage Services course. While the traditional methods used by the comparison group showed improvement, Nurturing Engagement and Lifelong Learning through Audio-visual (NELLA) demonstrated a clear advantage in accelerating learning and achieving deeper understanding.
