CHILDRENS MULTIMEDIA NUTRITION SIMULATION SOFTWARE

产品说明：这项研究的长期目标是开发和评估9至12奥尔兹多媒体营养模拟的知识和行为结果。 这种计算机模拟使用管理空间站食品供应的情景，将用于传达营养选择对癌症风险和心脏健康的影响。 在第一阶段，我们的健康教育，营养，评估，软件编程和多媒体设计专业人员的团队将开发和现场测试模拟原型软件。 通过焦点小组讨论，我们将评估软件的整体表现，用户界面和内容。 通过问卷，我们将衡量使用前到使用后的知识变化。 在第二阶段，模拟将扩大到包括更多的复杂性，研究设计纳入随机选择和分配到实验组和对照组，以及营养知识和行为变化的纵向测量。 最终产品将允许用户参与并观察进口食品、准备膳食、饲养和繁殖植物和动物以及测量营养变量的影响。用户还将收到有关短期和长期健康影响的反馈。 这款与互联网相连的产品将适合规模庞大且迅速扩大的家庭和学校儿童教育软件市场。

DESCRIPTION: The long-term aim of this research is to develop and evaluate knowledge and behavioral outcomes of a multimedia nutrition simulation for 9 to 12 year olds. This computerized simulation, using the scenario of managing the food supply of a space station, will be used to convey the effects of nutrition choices on cancer risk and heart health. In Phase I our team of health education, nutrition, evaluation, software programming, and multimedia design professionals will develop and field-test prototype software for the simulation. Through focus group discussions, we will evaluate the software's overall presentation, user interface, and content. With questionnaires we will measure pre- to post-use knowledge change. In Phase II the simulation will be expanded to include more complexity, a research design incorporating random selection and assignment to experimental and comparison groups, and longitudinal measurement of nutrition knowledge and behavior change. The finished product will allow users to participate in and observe the effects of importing food, preparing meals, raising and breeding plants and animals, and measuring nutrition variables. Users will also receive feedback on short and long-term health effects. This Internet-linked product will fit into a sizable and rapidly expanding home and school markets for children's educational software.
