Revise faster on YouTube by speeding up videos? Science says yes!

Since the start of the health crisis, many things have changed in our daily lives. In particular our way of working or studying. Yes, face-to-face, remote… These words are now an integral part of our vocabulary. For students, courses recorded and then made available online is a rather commonplace story today. And some view them in fast motion to save time. But is it really beneficial? A study by the University of California at Los Angeles (UCLA) seems to confirm this.

You learn just as well in a hurry!

Since the democratization of this way of studying, many studies have looked at the subject: does watching accelerated course videos not hinder learning? And often the results are very divided. Yes, no… In the end, no one agrees.

So UCLA did a new study on this and it seems that crash courses aren’t such a bad thing. idea. Indeed, the researchers selected 40 students and separated them into four groups for the experiment. One group viewed the course at normal speed, another 1.5 times normal speed, the third at double speed and finally, the last group followed the course 2.5 times faster.

After watching these videos for about a quarter of an hour, regardless of the speed, the students had to answer forty comprehension questions. And the verdict is astonishing: there is no big difference between the results of the students.

Those who followed the course at normal speed had, on average 26 good answers on 40 while the groups that watched it 1.5 times or 2 times faster gave 25 correct answers. On the other hand, it gets worse when you go too fast. Indeed, students who took the course at 2.5 times the speed did not have such good results with an average of /40.

A week later, the four groups were asked to answer further comprehension questions, on the same subject of course, in order to see what they really retained. And again, the first three groups had good results. So taking a crash course doesn’t hinder short-term or long-term understanding.

“Surprisingly, the speed of the video only has little impact on immediate and delayed comprehension at up to 2.5 times normal speed” , found Dillon Murphy, a doctoral candidate in psychology at UCLA. So, taking your courses in a crash course wouldn’t be such a bad idea. Beware, however, of more complex subjects perhaps.

Scientists have pushed the study further and it would be more relevant to watch a video twice in accelerated mode than once at normal speed. Like what…
