Video vs Real Life Demonstration

Department of Health and Physical Education (HPE)

This practice enhances health education by using interactive approaches such as video and real life demonstrations. University students could grasp the health-related knowledge better by using video demonstration than by using real life demonstration.

Situations where this practice can be used: 
This practice could be used in all health education and promotion seminars, especially when the target audience is university students.

This practice has been used in a health-related module within the Bachelor of Education (Honours) (Physical Education) and Bachelor of Science Education (Honours) (Sports Science) programmes (HKIEd).

Theoretical foundation: 

Recent learning theories stress the importance of interactive teaching and learning approaches in school environment. This practice is designed to improve the effectiveness of health education by using interactive approaches in university students.


1. Students were required to attend two health-related classes weekly. During the first three weeks, the lecturer presented some health-related contents (e.g., how to avoid shoulder disorders) in class by using video demonstration mainly. Students were allowed to question after watching the videos.
2. All students were then tested on their health-related knowledge in week 4 (test 1).
3. In the subsequent three weeks, the lecturer changed the presentation style from video demonstration to primarily real life demonstration (Fig. 1). Same as before, students were allowed to question and to discuss with the lecturer.
4. In the last week, all students were being tested on their health-related knowledge again (test 2).
5. Results of test 1 and test 2 were compared by paired t test. Alpha was set at 0.05 (two-tailed).
6. Feedbacks were obtained from students.

Supporting materials: 

Videos and photos are available.

Outcomes worth noting: 

Students (n=109) scored higher in test 1 (mean: 42.6±15.1) than in test 2 (mean: 39.5±15.8) (p=0.015). This hints that students grasp the health-related knowledge better by using video demonstration than by using real life demonstration.

Participants' response: 

1. “Both video and real life demonstrations by the lecturer are useful for us to learn about our body.”
2. “Use of videos could enhance our learning.”
3. “Good to show videos of the diseased populations in order to increase our health awareness.”

How this practice supports learning: 

. Include more videos and interactive discussions in University’s health education and promotion seminars.
. Real life demonstration may be used to supplement video demonstrations.


Using videos to present are more effective.
People can watch it again and again through their smartphone, iPad, computer and so on.
They can watch it even through they are working and walking on the street.

On the other hand, using the real life demonstrations are also a good way to teach people.
This can show them how to do it accurate directly.
The teacher/ coach can even help them to do it.
However, when the talk is finished, people cannot watch it again.
The worst thing is some people may not attend one of the lessons.

i agree that using video is more efficient that we can do the revision easily. i think real demobstration is good if the demonstrate can perform exactly the same every time

yes, if the real demonstration just have once only, that we cannot easy to follow and do the revision. Also that we cannot promote some new knowledge for people. because the real demonstration have the limited of the time and people.

I agree that using videos to present are more effective because students can watch the video anytime through the smart-products.

As a student who major in Physical Education or Sport Science, they should have the professional knowledge on health-related issues, such as anatomy and common disease. Video should be a good learning material because it can reuse for many times. Moreover, video's learning is easier to control by the students.

I would say that real life demonstration might be a example or detail information to ensure students' cognition and memories.

I agree with you. Videos can watch it in everywhere.
However, real life demonstration can show more details and give more interaction. For example, teacher or coach can not tell all the details which is keep the waist/spine straight when they doing the exercise. Moreover, teacher/coach invite audience to do that can let their body to remember the moves directly.

Nowadays, people are likely to use electric devices, like smartphone, computer to get the information because it is very convenience for everybody. I think the new education should using two ways to present the information, it can let more and more students to get the information and using the real life demonstration can help someone to catch up some information who haven't catch it. It is a very convenient idea for everyone.

videos can watch in everywhere and watch many times. after years, it stills here for people to remind.

I think the video and real life demonstrations are interesting. It is because we reading a lot of words on our studying life. Someone may think reading is boring. Therefore, the video and real life demonstrations can help them to pay attention in class. Moreover, the image can help us to remember some step or procedure more easily.

Video could draw people attention and it is an interesting present skills.Too much word would let people feel bored and decreased their interest of learning.Moreover,sometimes movement or exercise post is very difficult to describe in words and also for understanding.Using a 5-10mins video instead of using 3000 words to describe the content would be more friendly to the audience.
In addition, real life demonstration could increase the trustworthy of the actions,to ensure the actions could be applied.

I think the major point of effective of video demonstration is the students can understand the knowledge and throw into the situation easily. Moreover, they can enjoy the video whenever and wherever they are because they can enjoy the video through the ipad or tablet, smartphone and computer which connecting to the internet.
