Evaluation planing

Today, we have started our evaluation. For question 4, I had an idea to show 5 students who has not seen the film and film their reaction while watching the film on camera. Also a teacher. After they finish watching the film I have created 3 questions to ask which are:
1) What was the plot of the sequence you just watched?
2) Would you watch the rest of the film?
3) What went well and what would you improve?

I thought to ask a teacher aswell because I think they would have a very different opinion to the students, and this will have an understanding of the target audience. 
Also when we are going to ask the students, we will ask mixture of races and gender so there will be a fair judgement. 

The way I am going to film this clip was inspired by watching "Kid's Reaction To.." videos which I've found on YouTube.
