Students' Behavior and Perceptions Regarding Complementary Videos for Introductory Physics Courses in an Online Environment

Featured Application This works can help to choose the better and more efficient videos for professors of Physics courses. Digital videos have an important and increasing presence in student learning. They play a key role especially in subjects with high mathematical content, such as physics. However, creating videos is a time-consuming activity for teachers, who are usually not experts in video creation. Therefore, it is important to know which kinds of videos are perceived as more useful by students and why. In this paper we analyze students' perception of videos in an introductory physics course of engineering with over 200 first year students in a 100% online university, Universitat Oberta de Catalunya (UOC). Students had 142 videos available of several types. We followed a qualitative methodology from a ground theory perspective and performed semi-structured interviews. Results show that students found videos as the most valued resource, although they considered that videos cannot substitute text documents. Students valued human elements and found them in videos where the hands of the professor appear. Finally, students consumed videos according to the course schedule, visualized the whole video the first time, and consumed it later according to further deliveries and exams. The main contributions of this paper were analyzing the perception of students from a qualitative perspective in an introductory course of physics in engineering, obtaining the main elements that make videos useful for students and showing that videos with hands are valued by students.
