| Outline of Final Research Achievements |
The estimation of food portion size is a necessary skill for dieticians and clients so that they both can assess the clients' food intake.This study aims to develop an online eLearning program to increase skills in food portion size estimation, and to provide guidelines to improve learning effectiveness.Learning effectiveness was confirmed through using 3-dimensional food images to solve difficulties with spatial perception, such as those for 2-dimensional food images, and a real digital scale, which enabled adjustments of real food size in this eLearning program.
After nutrition students completed six weeks of training, the study group exhibited decreases in estimation errors for all food (25 foods), excluding seasoning. The study group also had stronger intentions to estimate food portion size than did the control group. Training was effective at increasing both skills and intentions. This eLearning program is expected to be a useful educational tool in nutrition education.
