Science is a body of knowledge that explains the phenomena of our world through observations and experimentation. Many nations have developed because of the attention they give, and the investment they put into science education. However, globally, students’ interest in science tends to wane and so is a drop in their numbers as they transition from elementary to secondary schools. Many factors were associated with the cause in the drop of students’ numbers and interest.

Since observations and experiments are the fundamentals in science teaching, we propose the use of YouTube STEM videos as effective learning resources for the teaching of science in high schools. This approach could potentially help to bridge the gap between theory and practice and likewise help to reverse the perception about science. For instance, YouTube STEM videos could motivate students, especially those in the underprivileged schools that lack the basic science resources to take up science programs. The study reviewed previous studies and conducted an empirical study with selected Estonian high school teachers to have their perspectives and insights into using YouTube videos to teach STEM subjects. Interviews with open-ended questions were administered to participants to have their perspectives and insights on teaching STEM lessons with YouTube videos. Results show that all participating teachers find YouTube videos more interactive and effective for STEM teaching and learning. Hence, the increase in the frequency of its use in teaching.
