Hi,

I hope this article can help you:

Salem, Y., Gropack, S. J., Coffin, D., & Godwin, E. M. (2012). Effectiveness of a low-cost virtual reality system for children with developmental delay: a preliminary randomised single-blind controlled trial. Physiotherapy, 98(3), 189-195.‏

Thank you very much Sir...

I the question needs to be focus in a different way.

Let me give this example:

Is there a tool to measure the impact of books in education?

well what type of use are people giving these books we are talking about? are they using them to create book towers? are students just carrying them in their backpacks? are they reading them? how often? are they math books, or history books (if you are giving students math problems to measure the impact of history books, then you'll find that the history books did not help students to become better at math.) 

So what is the purpose of the virtual reality application that you want to test with children? e. g. if the purpose is to teach children how to jump, then the tool to measure the impact is a measuring tape. If the application teaches them to run then a stopwatch might be useful. If the application teaches maths then a math test might be useful. 

Once you specify the purpose of the specific VR application that you want to use, then you can identify what would be relevant to measure, and after that you can start thinking on what tools are available to measure this property that you selected. 

Hi,

Hope the attached literature will be of assistance to you.

Best wishes!

Article Risk Analysis (Assessment) Using Virtual Reality Technology ...

I do not know? Sorry.

if its blind children..they have visual impairment and are blind..so the media that plays an important role is their aural or hearing..and touch...so i think you have to very specific.  Today technology plays a major role in their education. Coursewares like OPEN BOOK, JAWS etc are commonly used by our pupils in schools and universities. Your question is very vague and very broad.. If you want to know the impact of the coursewares etc. I think descriptive and prescriptive methods would suffice, unless someone has come up with an electronic gadget with wires attached to the brain, etc sorry, till today  i'm not aware of those in Malaysia      

Thank you very much, I am heartily appreciating your responses and suggestions.

The main focus of my work focuses on the teaching science subject to Junior blind students studying in class 6,7 or 8.  

So I appreciate and Welcome your all responses.

                                                                                                       Thanking you ,

If it is just about measuring impact. I would keep it simple. 

Test their knowledge before using the virtual reality app. 

Test their knowledge after using it. 

Thanks again Sir. Mainly I want to measure the impact of Virtual reality on conceptual understanding and science process skill by blind students. As reviewing literature what i learn is that teaching science concept to blind students are difficult due to its abstract nature,but in the mean while it is also true that blind people have disability of eye not the mind and so have the same mental process but they see the world differently. I want to teach science subject to blind students with the use of Virtual reality technology, and it is difficult for me to choose appropriate Virtual Reality technology which works for both blind and low vision children and up to what level science can be understand by blinds.
