Comprehension is the primary objective reading, which promotes cognizance in all disciplines and so improves the teaching-learning process. The objective of this research was to see how SQ3R affected the reading comprehension of Grade 11 students at the Palompon Institute of Technology. The pretest-posttest control group design was employed in this research. Sixty Students randomly assigned to either of the groups. To gather the data, a reading comprehension test was used. It was treated using the mean and t-tests for dependent and independent samples. The following findings were revealed: 1) The initial reading comprehension of the SQ3R was “fair to good†while the conventional reading strategy was also “fair to good.†2) The students’ initial reading comprehension was of the same level; 3)The final reading comprehension of the SQ3R was better than the conventional reading strategy ; 4) A significant difference was found between the initial and final reading comprehension of the students exposed to the SQ3R as well as those to the conventional reading strategy; and 5) There was a significant difference between the reading comprehension of the students exposed to the SQ3R and to the conventional reading strategy. This means that the SQ3R is a more effective strategy than conventional reading in the development of the students’ reading comprehension. On the above findings, it was concluded that students need a different reading strategy to improve their reading comprehension, but they perform better if they use the SQ3R instead of conventional reading strategy.
