This study examines how different classroom strategies influence learners’ academic outcomes. Specifically, it investigates the extent to which teachers employ differentiated instruction, student engagement strategies, contextualized learning materials, and the integration of real-world scenarios. The study also assesses learners’ academic performance in English, Mathematics, and Science, exploring significant relationships between teaching strategies and student achievement. A descriptive-correlational design was used, involving 30 teachers and 162 learners as respondents. Data were collected through validated survey questionnaires and analyzed using weighted mean, Pearson correlation, and t-tests. Findings revealed that teachers strongly agreed they frequently used all four strategies, with differentiated instruction and real-world scenarios being the most consistently applied. Learners demonstrated high performance across all subjects, with outstanding results in English and very satisfactory ratings in Mathematics and Science. Significant relationships were identified between differentiated instruction and real-world scenarios and overall academic performance, while student engagement strategies were particularly linked to improved Mathematics and Science outcomes. Contextualized learning materials, though commonly used, did not show a strong direct correlation with higher grades in this study. The results highlight the importance of personalizing lessons and connecting content to real-life contexts to enhance learning. The study recommends further training, resource provision, and professional collaboration to sustain effective practices. An enhancement plan was developed to guide continuous improvement in instructional strategies, aiming to strengthen learner engagement and achievement.
