How Physics Teaching is Presented on YouTube Videos

One hundred and twenty videos on YouTube were selected and investigated in terms of content relating to physics and science teaching. This video material was used to generate categories that were then applied to three investigations: physics as taught in upper secondary school and in the introductory level at university, physics projects in upper secondary school, and science in preschool. The results revealed different practices for the use of YouTube in physics and science teaching. One practice, in upper secondary school and at the introductory level at university, was to display physics based on traditional lectures that were video recorded. Another practice was the presenting of students' projects, and a third was support for preschool teachers as a means of promoting science material for their teaching needs.
