This study examined the influence of teacher enthusiasm on innovative teaching strategies among 138 elementary teachers in the Division of Davao del Norte. Using a quantitative descriptive-correlational research design, the study employed adapted and validated survey instruments to measure teacher enthusiasm, categorized into teaching enthusiasm and subject enthusiasm, and innovative teaching practices, which included critical thinking, creativity, social skills, and ICT skills. Data were analyzed using Weighted Mean, Pearson Product Moment Correlation, and Multiple Regression Analysis at a 0.01 level of significance. Findings revealed that both teacher enthusiasm and innovative teaching strategies were at an extensive level, indicating that these constructs were oftentimes evident among the respondents. A strong and significant positive relationship was found between teacher enthusiasm and innovative teaching strategies. Regression analysis further demonstrated that both teaching enthusiasm and subject enthusiasm significantly predicted innovative teaching strategies, collectively explaining a substantial proportion of the variance. The results suggest that teachers’ passion for teaching and excitement about their subject matter play a critical role in fostering creativity, reflective thinking, collaboration, and effective technology integration in the classroom. The study highlights the importance of sustaining teacher enthusiasm to strengthen instructional innovation and improve educational quality.
