The objective of the study was to determine the effect of nutrition instruction, using the curriculum guides, Nutrition In A Changing World, A Curriculum for Junior High Health, and A Curriculum for Senior High Health, on improving the nutrition knowledge, selected food/nutrition attitudes, and dietary behavior of students enrolled in secondary level health courses. Three groups of students were utilized including one experimental and two control groups at each level (junior high and senior high). The experimental group was pretested, taught the nutrition curriculum, and posttested. One control group was posttested only to measure the effect of the pretest on posttest performance. A second control group was pretested and posttested. Neither control group received nutrition instruction until after the study was completed. The three instruments used to collect data were a nutrition knowledge test, a food/nutrition attitude instrument, and a food frequency form. The results indicate that, at all grade levels, the experimental group had significantly improved knowledge scores. Little change in attitude scale scores was noted in grades seven and eight, while ninth grade experimental students scored significantly higher on the posttest for all attitude scales. Little improvement was seen in the posttest food frequency scores.
该研究的目的是确定使用课程指南《变化世界中的营养》《初中健康课程》和《高中健康课程》进行营养指导，对提高参加中等水平健康课程的学生的营养知识、选定的食物/营养态度和饮食行为的影响。研究使用了三组学生，包括初中和高中各一个实验组和两个对照组。实验组进行了预测试、接受了营养课程教学并进行了后测试。一个对照组仅进行后测试，以测量预测试对后测试成绩的影响。第二个对照组进行了预测试和后测试。在研究完成之前，两个对照组均未接受营养指导。用于收集数据的三种工具分别是营养知识测试、食物/营养态度工具和食物频率表。结果表明，在所有年级，实验组的知识得分都有显著提高。七年级和八年级的态度量表得分变化不大，而九年级实验组的学生在所有态度量表的后测试中得分显著更高。后测试的食物频率得分几乎没有改善。
