DESCRIPTION (provided by applicant): The long-term objective of this SEPA project is to design and field test a science-enriched middle school healthful living curriculum to increase students' knowledge and interest in health-related science, enhance their intention to pursue a life science-related career, and improve the communities' understandings of NIH funded clinical and basic research. In 2010 the Trust for America ranked North Carolina (NC) as the state with the 10th highest rate of obesity in the nation. Currently, more than one third of NC adolescents and two thirds of adults are overweight or obese. Six local education associations (LEAs) in the Piedmont region of NC will partner with scientists and educators on this SEPA team to design and evaluate The Science of Healthful Living Curriculum (HLC). The HLC will be based on the National Science Content Standards and the NC Standard Course of Study for 6th-8th grade students. Currently, the six LEA partners do not have a HLC based on the NC Standard Course of Study. This SEPA middle school HLC will use student-centered modules to help teens examine the effects of their physical activity and nutrition choices on body systems. The specific aims of this SEPA project are to evaluate the extent to which (Aim 1) the science-enriched HLC can increase students' knowledge of health-related science and the science inquiry process; (Aim 2) students' personal experiences with the HLC can increase their interest in and understanding of effective science practices and their vision of themselves as future scientists; and (Aim 3) students' participation with their families in HLC-related events can increase their family's trust in and use of NIH-sponsored research results, enhancing their life and health choices. The HLC will be assessed during funding Yrs 2 - 3 using a randomized clinical trial in which 20 middle schools, representing the 6 LEA partners, will be assigned to either experimental (HLC) or control conditions. Curricular effects will be analyzed using a hierarchical linear modeling design. The professional development plan includes extensive teacher training throughout the funding period, increasing teachers' science knowledge and ability to use science-education teaching strategies. At the conclusion of the clinical trial period, the curriculum will be disseminated locally and nationally to new middle schools within 3 teacher support conditions: sustaining, full, and web-based. The dissemination will be evaluated using a quasi-experimental design in funding Yrs 4 - 5 to test the effectiveness of the three dissemination conditions. Health and physical education teachers will implement the HLC in their classes. The Healthful Living concept reflects a deep integration of Life and Health-related Science Standards taught using a constructivist, student centered approach to the scientific inquiry process. The HLC leverages instructional time currently allocated to health/physical education to increase time for science education. As a result of this SEPA, over 33,000 young adolescents will conduct experiments examining the effects of healthful living choices on weight and stress management and preventable diseases, such as Type II diabetes and many heart related illnesses and events.

描述（由申请人提供）：该 SEPA 项目的长期目标是设计和现场测试科学丰富的中学健康生活课程，以增加学生对健康相关科学的知识和兴趣，增强他们追求健康的意愿。生命科学相关的职业，并提高社区对 NIH 资助的临床和基础研究的了解。 2010 年，美国信托基金会将北卡罗来纳州 (NC) 列为全美肥胖率第十高的州。目前，超过三分之一的北卡罗来纳州青少年和三分之二的成年人超重或肥胖。北卡罗来纳州皮埃蒙特地区的六个当地教育协会 (LEA) 将与该 SEPA 团队的科学家和教育工作者合作，设计和评估健康生活科学课程 (HLC)。 HLC 将基于国家科学内容标准和 NC 标准学习课程（针对 6-8 年级学生）。目前，六个 LEA 合作伙伴没有基于 NC 标准学习课程的 HLC。这个 SEPA 中学 HLC 将使用以学生为中心的模块来帮助青少年检查他们的身体活动和营养选择对身体系统的影响。该 SEPA 项目的具体目标是评估（目标 1）科学丰富的 HLC 在多大程度上可以增加学生对健康相关科学和科学探究过程的了解； （目标 2）学生在 HLC 中的个人经历可以增加他们对有效科学实践的兴趣和理解，以及他们对自己作为未来科学家的愿景； （目标 3）学生与家人一起参与 HLC 相关活动可以增加家人对 NIH 资助的研究成果的信任和使用，从而改善他们的生活和健康选择。 HLC 将在资助第 2 - 3 年期间通过随机临床试验进行评估，其中代表 6 个 LEA 合作伙伴的 20 所中学将被分配到实验 (HLC) 或对照条件。将使用分层线性建模设计来分析课程效果。专业发展计划包括在整个资助期内进行广泛的教师培训，提高教师的科学知识和使用科学教育教学策略的能力。临床试验期结束时，该课程将在 3 个教师支持条件下向当地和全国的新中学传播：持续、全面和基于网络。将在第 4-5 年资助中使用准实验设计来评估传播，以测试三种传播条件的有效性。健康和体育教师将在课堂上实施 HLC。健康生活的概念反映了生命和健康相关科学标准的深度整合，采用建构主义、以学生为中心的方法进行科学探究过程。 HLC 利用目前分配给健康/体育教育的教学时间来增加科学教育的时间。作为这项 SEPA 的成果，超过 33,000 名青少年将进行实验，研究健康的生活方式选择对体重和压力管理以及可预防疾病（例如 II 型糖尿病和许多与心脏相关的疾病和事件）的影响。
