Technology is now considered a way of life for people that its utilization cannot be ignored if schools are responsive to the demands of globalization. The study aimed to determine the level of efficacy of technology in reinforcing the performance tasks in English of the Grade 10 students of Pundasan National High School, Gingoog City. The researcher used an experimental design. A test was designed to determine the level of efficacy of technology in reinforcing the performance tasks in English administered to the 50 respondents after six weeks of treatment through teacher modeling. The treatment was carried out with the combination of lecture, discussion, and demonstration of the application of technology as a tool for students in completing the performance tasks in English. The statistical treatments applied were frequency and t-test. The overall result indicated that there is a significant difference tested at 0.05 level between the level of efficacy of technology in reinforcing the performance tasks in English before and after the treatment. Teacher modeling on the application of technology as treatment was found to be efficient in helping students use blogging, info graphics, digital scrapbooking and digital storytelling in completing the performance tasks.
