Developing stages of the App by ADDIE model
The ADDIE model : The five phases-Analysis, Design, Development, Implementation, and Evaluation-represent a dynamic, flexible guideline for building effective training and performance support tools
Core elements for the development of the App contents
Contents of the classroom education by using developed App
Comparison of the levels of knowledge, attitude and behavior of treatment and control groups before using the App1)
1) 5-point Likert scale questions: 1 for strongly disagree, 2 for disagree, 3 for neutral, 4 for agree, and 5 for strongly agree
2) T: Treatment group (n = 27)
3) C: Control group (n = 27)
4) Mean ± SD
Comparison of the treatment and control groups with regard to the scores of correct answers on nutritional knowledge before and after using the App1)
1) Multiple choice questions
2) T: Treatment group (n = 27)
3) C: Control group (n = 27)
4) N (%)
5) Mean
*: p < 0.05, **: p < 0.01, ***: p < 0.001
Changes of nutritional knowledge, attitude and behavior in the treatment group of the App1)
1) 5-point Likert scale questions: 1 for strongly disagree, 2 for disagree, 3 for neutral, 4 for agree, and 5 for strongly agree
