CHILDREN'S MULTIMEDIA NUTRITION SIMULATION SOFTWARE

该项目的长期目标是开发、评估和传播一种多媒体营养软件产品，使9至12岁的儿童能够积极参与营养知识的学习。用户操纵的计算机模拟将被用作工具，以提高适龄营养知识，行为和应用的食物选择技能。模拟将使用3d动画、音乐和音效来描绘火星殖民地。四种模拟——自助餐厅、运动队、探险和营养不良——被设想出来。我们将进行两个层次的评估；在产品开发过程中的测量，以及干预的随机试验的结果评估。我们将测量治疗前和治疗后的变化：1)关于营养成分食品标签的知识，以及与总脂肪、饱和脂肪、胆固醇和膳食纤维相关的癌症和心脏病风险；2)将营养成分食品标签应用于行为选择，包括每天食用新鲜水果和蔬菜，减少每日总脂肪、饱和脂肪、胆固醇和膳食纤维的摄入量；3)展示自己和他人的营养计划技能。内置的Web链接允许用户访问更多的营养信息，下载有关新食品的营养信息，并与其他用户和专家进行交流。建议的商业应用：华盛顿特区的国家卫生博物馆将在其商店和国际分发的目录中出售我们的软件（见附录A中的信件）。使用点是娱乐和学校软件市场。随着PC普及率的提高和消费支出的增长，2001年互动娱乐市场将达到116亿美元，比1997年的55亿美元增长112.9%。到1999年，电子教学材料在学校的销售额将超过10亿美元。

The long-term goal of this project is to develop, evaluate, and disseminate a multimedia nutrition software product that enables active participation in learning about nutrition for 9 to 12 year-olds. User manipulated computer simulations will be employed as tools to improve age appropriate nutritional knowledge, behavior, and application of food choice skills. The simulations will portray a Martian colony using 3-D animation, music, and sound effects. Four simulations - a cafeteria, sports teams, exploration, and malnourishment - are envisioned. We will conduct two levels of evaluation; process measures during product development, and outcomes assessment in a randomized trial of the intervention. We will measure pre- to post-treatment changes in: 1) knowledge about the Nutrition Facts food label, and the cancer and heart disease risks associated with total fat, saturated fat, cholesterol, and dietary fiber; 2) application of Nutrition Facts food labels to behavioral choices, including eating fresh fruits and vegetables daily, and decrease in daily intake of total fat, saturated fat, cholesterol, and dietary fiber, and; 3) demonstration of skills on nutritional planning for oneself and others. A build-in Web link to allow users to access more nutrition information, download nutritional information on new food products, and communicate with other users and experts. PROPOSED COMMERCIAL APPLICATIONS: The National Health Museum in Washington, D.C. will make our software available for sale in their store and internationally distributed catalogues (see letter in Appendix A). Points of use are the recreation and school software markets. Driven by increasing PC penetration rates and growing consumer spending, the market for interactive entertainment will reach $11.6 billion in 2001, a 112.9% increase over the $5.5 billion spent in '97. Sales of electronic instructional materials will exceed $1 billion in school-only sales by 1999.
