Abstract
This paper aims to examine changes in students’ attitudes towards nutrition through education. Twentyseven senior high school students developed lesson plans with the title “food education for five minutes during school lunch time” for reading and communication activities of home economics class. The lessons were designed for elementary school children. The students answered a pre and post questionnaire, the activity was carried out in order to assess any changes in their own attitudes towards nutrition. The subjects were 12 in an experimental group and 15 in a control group. The results of the questionnaire were analyzed utilizing a t-test and a two-way factorial analysis of variance was performed. The study analyzed how their attitudes towards were changed through Modified Grounded Theory Approach (M-GTA). There were two key results: 1) The post -test score on average of the experimental groups was higher than the pre-test average. 2) By analyzing the students’ personal descriptions, they showed meaningful improvement of their attitudes towards nutrition with a three-step process.
