This study investigates the different learning delivery modalities used by science teachers, academic performance of Grade 11 students in science, when grouped according to learning delivery modalities and the problems encountered by the science teachers in the use of different learning delivery modalities for the school year 2020-2021 at one division of Southern Luzon. The researcher utilized a descriptive correlation type of research using a questionnaire to carry out the study. The findings revealed that majority of the science teachers in the Senior high school were teaching modular distance among other modalities. Among them, students perform well in online distance learning, which can be attributed to the idea that they are all Science and Technology Engineering and Mathematics (STEM) students, and those students in other modalities were regular students at the school. It is recommended that Science teachers may continue to attend seminars, trainings, and workshops in various levels such as the school, division, national or international levels to further enhance more their knowledge about the implementation of learning modalities in the new normal class. Also, the Department of Education through science education department may craft supplemental learning materials such as modified learning modules to the students.
