Faster YouTube review by speeding up videos? Science says yes!

Since the beginning of the health crisis, many things in our daily lives have changed. In particular our way of working or studying. Yes, face to face, distance … These words are now an integral part of our vocabulary. For students, lessons that are recorded and then made available online, is a rather trivial story today. Some watch them at an interval to save time. But is it really useful? A study from the University of California, Los Angeles (UCLA) seems to confirm this.

We learn at the same speed!

Since the democratization of this method of study, many studies have looked at this topic: Does watching videos of intensive courses hinder learning? The results are often very divided. Yes, no … Finally, no one agrees.

So UCLA did a new study on this and it seems like disrupting courses isn’t a bad idea. In fact, the researchers selected 231 students and divided them into four groups for the experiment. One group watched the course at normal speed, the second group watched the normal speed 1.5 times, the third watched at double speed, and finally, the last group followed the path 2.5 times faster.

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

Those who took the course at a normal speed got, on average, 26 out of 40 correct answers, while groups that watched it at speed 1.5 or twice the fastest gave 25 correct answers. On the other hand, it spoils when you go too fast. In fact, students who followed the course 2.5 times faster did not get such good results with an average of 22/40.

After a week, the four groups were asked to answer more comprehension questions, on the same topic of course, in order to see what they actually took. And again, the first three groups did well. Thus, taking an intensive course does not hinder comprehension in the short or long term.

Surprisingly, video speed has very little effect on instant and delayed comprehension up to 2.5 times the normal speed., found Dillon Murphy, a doctoral student in psychology at the University of California. So taking intensive training courses would not be a bad idea. Be careful but maybe with more complex topics.

The scientists pushed the study forward, and watching a video twice at high speed than once at normal speed would be even more important. like what…
