Watching the recording at a higher speed is also an effective way to learn

A new study by scientists from University of California, Los Angeles It shows that students remember information surprisingly well when viewing recordings at twice the playback speed.

as he knows Alan Castle, the study author and professor of psychology, however, has a lower upper bound that students remember than when viewing standard recordings.

in experience 231 students were instructed to watch two films of several minutes each. One was about the Roman Empire and the other was about property valuation. The students were divided into four groups. One watched the video at normal speed, another watched the video at 1.5 times the playback speed, the third watched the video at twice the speed, and the last watched 2.5 times the playback speed. They were instructed not to pause videos or take notes while watching them.

After watching the recordings, students answered multiple choice and true-false questions. The group watching movies at normal speed scored the most points. They score 26 out of 40 possible points. Then 25 points were scored by students from groups that watch movies 1.5 times and double their playback speed. It turns out that only the students who watched the recordings at the fastest pace scored significantly fewer points, 22 to be exact.

A week later, the question tests were repeated. The results were similar to the previous results. Scientists just said that Watching the recordings at an acceleration rate of 2.5 times resulted in students less understanding and remembering the content.

The research was performed in a few other groups. The students were instructed to watch the recordings, first with the accelerator films, then without, or vice versa. All tests confirmed the general conclusion that viewing the recording at a maximum playback speed twice does not interfere with reception and allows for effective learning.

“Students can save time and learn more efficiently by watching pre-recorded lectures at a higher speed if they use the time saved in additional study,” he said. ” Dillon Murphy, PhD in Psychology, Research Co-Founder – However, we caution against using this strategy only to save time.

Scientists note that Video acceleration method may not be effective In the case of particularly complex or difficult training materials.

The results of the research were published in a scientific journal Applied Cognitive Psychology.
