Integrating Physics in Disaster Risk Reduction (DRR) through YouTube Videos

This paper is focused on the integration of physics in Disaster Risk Reduction (DRR) using a Web 2.0 tool, YouTube and its effect on the students' understanding of the physics of DRR. There were 96 senior high school students from the General Academic Strand (GAS) who were taking Disaster Risk Reduction (DRR) Management subject in one semester of School Year 2019-2020 in one of the public school institution in Bacoor City, Cavite. One of the required outputs in the subject is to develop a community preparedness plan to lessen and avoid the effect of different disasters. However, the student participants did not have any physics subject in the entire school year yet had physics classes when they were in Grade 7 to Grade 11. YouTube videos were used to help the students revisit and connect those physics lessons to their DRR lessons. The YT videos were selected by the researchers and was checked and validated by the DRR teacher. The video links were given to the students at the start of the discussion of the specific DRR lesson and formative tests were given at the end of each lesson. Results showed that there was an increasing mean formative test scores and that the DRR teacher observed that students became more interested in the lessons. It was noted that students became more active in class and some were able connect physics concepts in their DRR lessons as they explain and give examples. Students' responses to the questionnaire also revealed that YT videos helped the students understand the physics concepts of DRR and that it taught them to be an independent learner. Further, specific cases and/or situations that limit the students from recommending the use of YT videos in their other subjects was elucidated.
