Watching A Lecture Twice At Double Speed Can Benefit Learning Better Than Watching It Once At Normal Speed

new paper in Applied Cognitive Psychology….

231 student participants to watch two YouTube videos (one on real estate appraisals and the other on the Roman Empire) at normal speed, 1.5x speed, 2x speed or 2.5x speed. They were told to watch the videos in full screen mode and not to pause them or take any notes. After each video, the students took comprehension tests, which were repeated a week later. The results were clear: the 1.5x and 2x groups did just as well on the tests as those who’d watched the videos at normal speed, both immediately afterwards and one week on. Only at 2.5x was learning impaired.

When the team surveyed a separate group of UCLA students, they found that a massive 85% usually watched pre-recorded lectures at faster than normal speed. However, 91% said they thought that normal speed or slightly faster (1.5x) would be better for learning than 2x or 2.5x. These new results certainly suggest that this isn’t right: double-time viewing was just as good as normal viewing.

While 2x viewing was fine for learning about the material in their studies — real estate appraisals and the Roman Empire — perhaps it might not work for more complex subject matter; again, only more research will tell.

How Social Media Is Being Used In Education

good graph on the bottom of the article (http://www.edudemic.com/wp-content/uploads/2013/10/social-media-for-teaching.jpg)

  • The level of personal use of social media among faculty (70.3 percent) mirrors that of the general population
  • 55 percent of faculty use social media in a professional context (any aspect of their profession outside of teaching), up from 44.7 percent last year
  • Only 41 percent of faculty use social media in the classroom, but this use continues to experience steady year-to-year growth
  • Faculty are sophisticated consumers of social media. They match different sites to their varying personal, professional, and teaching needs
  • Concerns remain about privacy, maintaining the class as a private space for free and open discussion, and the integrity of student submissions
  • Most faculty agree that “the interactive nature of online and mobile technologies create better learning environments” and that digital communication has increased communication with students
  • Faculty believe that online and mobile technologies can be distracting, and that they have resulted in longer working hours and more stress
