Development and Evaluation of The Use of The Food Exchange Game in The Learning of Staff in The Working-Age Health Promotion Project : A Case Study Comparing Knowledge and Satisfaction Results by Analyzing Data Using the Wilcoxon Signed Ranks Test

Abstract

This study aimed to 1) compare knowledge levels before and after learning with the food exchange game category and 2) evaluate satisfaction with the learning media related to the food exchange game category. The sample consisted of 20 staff members from the Health Promotion Project for Working-Age Adults at Samut Sakhon Hospital, aged 35 years and older. The instruments used were 1) a knowledge test on the food exchange category and 2) a satisfaction assessment form for the learning media on the food exchange category. This was a single-group study with pre- and post-tests. Data were collected by administering a knowledge test before and after learning with the food exchange game category and a satisfaction assessment form for the learning media on the food exchange game category. The data were then analyzed using t-tests, with the mean, standard deviation, and comparative analysis of differences in mean knowledge before and after learning with the food exchange category, assessed by the Wilcoxon Signed Ranks Test.
The results showed that the sample group’s knowledge score before using the food exchange game had an average of 7.15 points, which increased to an average of 9.35 points out of a full score of 10 points after using the game. The Wilcoxon Signed Ranks Test yielded a Z value of 3.865, statistically significant at the p < .001 level. Furthermore, the trainees reported the highest levels of satisfaction with the food exchange game media in terms of content, format, components, and practical application. This food exchange game media helps reduce the cost of preparing actual food and is a suitable option for teaching nutrition education.
