The research study investigates the impact of audiovisual aids, specifically Microsoft PowerPoint presentations, on the teaching-learning process of senior high school students at the College for Research and Technology in Cabanatuan City for the academic year 2016-2017. Findings indicate that while the use of PowerPoint presentations did not show a significant relationship with students' academic performance, their attitudes and teacher's techniques during the presentations did have a positive impact. The study recommends enhancing curriculum with effective audiovisual materials and adapting teaching methods to improve student engagement and performance.
