title: Comparison of the Educational Effect upon Myopia Prevention and Treatment between Video Demonstration and Traditional Teaching.
abstract: OBJECTIVE
  To compare the education effect of video demonstrations and conventional teaching on the prevention and control of myopia.
  
  
  METHODS
  Eighty students were randomly divided into an experimental (n = 40) and a control (n = 40) group, and each group was split into two classes of 40 students. The students in the experimental group attended classes mainly based on video demonstration and those in the control group received conventional teaching. All students then undertook a test and the examination scores were statistically compared between the two groups.
  
  
  RESULTS
  The educational background, age, and gender did not differ between the two groups (all P > 0.05). The experimental group had a mean test score of 8.25 ± 1.45, which was slightly lower than the mean of 8.58 ± 1.11 in the control group, but the difference was not statistically significant (t = -1.589, P = 0.114).
  
  
  CONCLUSIONS
  The educational effect of video demonstrations was almost identical to that of traditional teaching. In addition, video classes reduced the training time and financial costs, indicating that they deserve widespread application.
