A study on video usage in the classroom found that 71% of responding educators believe the optimal length for viewing is 10 minutes or less. Another 28% preferred videos between 10-30 minutes in length, according to a report in THE Journal.
Authors of the report, The State of Video in Education, felt shorter videos could reflect the fact that students are used to watching videos on YouTube, while the longer lengths might relate to the popularity of the 18-minute TED Talks video format.
The research also found that 91% of the respondents said video had a positive impact on student satisfaction and 82% said it led to higher student achievements. At the same time, 83% of the educators said that ease of use continues to be the biggest need to bring video to the classroom, while 60% reported needing more training and support on tools already available.
“The data in this survey firmly suggest that video technology is a major force in education,” the report concluded. “In the future, students will expect video to be a part of their learning experience and will generate more video content. In 10 years’ time, video will become a standard part of education, will evolve beyond delivery of content, and enable innovative types of teaching and learning. It will gradually take the place of textbooks and will become an increasingly important skill in itself, participating in a shift in the role of the educators.”
