Developing And Testing An Implementation Strategy For Active Learning To Promote Physical Activity In Children

促进青年人的体育活动对于预防心血管疾病至关重要。尽管可用 尽管对体育活动采取了循证办法，但实施工作仍然是一项挑战，特别是在学校。 因此，迫切需要制定有效的执行战略， 和实施以证据为基础的儿童体育活动方法。这四年的目的 K 01奖是准备博士蒂莫西J.步行者与必要的培训和经验，以实现他的职业生涯 目标是成为一个独立的调查员和领导者在实施科学和物理领域 活动推广。该建议包括三个培训目标：1）熟练执行 研究; 2）建立分析技能，使用多层次模型和贝叶斯统计方法， （三）加强学校体育活动研究能力。 博士步行者已经组建了一个指导小组的专家在实施科学（博士玛丽亚费尔南德斯， 主要导师），应用统计方法（查尔斯绿色博士，共同导师），和身体活动研究 (Drs. Harold Kohl和John Bartholomew，共同导师）。拟议的研究旨在改善 实施主动学习，这是一种以学校为基础的循证方法， 进入学术课程。研究的基本原理是，积极的学习方法是有效的， 增加儿童的身体活动，但在研究中存在很大的差距， 实践研究的目的是：1）制定一项实施战略，以改善使用和维持 在小学采用积极的学习方法，2）进行可行性研究，评估 制定了关于主动学习的实施和效果的实施策略。目标1将 使用干预地图，一种系统的方法来开发一个以科学为基础的多方面 实施战略目标2将使用准实验设计来检查 实施策略及其对实施保真度影响。目标2还将审查初步的 积极学习的有效性。这项研究非常重要，因为它解决了 迫切需要执行支助的学校儿童。如果有效，发达国家 实施战略有可能改善主动学习的使用，并惠及数百万学生 在美国各地。这项研究是创新的，因为它针对一种新的主动学习方法， 关于支持使用这些方法的执行战略的研究有限。它还使用了一本小说 框架来指导实施战略的制定，贝叶斯统计方法来确定 实施战略是否值得进一步测试。这项研究的结果将提高 to scale-up规模up physical体育activity活动approaches方法in schools学校.数据还将用于寻求R 01资金， 规模试验，这将进一步支持步行者博士的过渡到研究独立。

Physical activity promotion among youth is critical for cardiovascular disease prevention. Despite available evidence-based approaches for physical activity, implementation remains a challenge, especially in schools. Therefore, there is an urgent need to develop effective implementation strategies to improve the dissemination and implementation of evidence based physical activity approaches for children. The purpose of this four year K01 award is to prepare Dr. Timothy J. Walker with the training and experience necessary to achieve his career goals of becoming an independent investigator and leader in the field of implementation science and physical activity promotion. This proposal includes three training objectives: 1) gain proficiency in implementation research; 2) build analytic skills to use multilevel models and Bayesian statistical approaches in implementation research; and 3) increase competency in conducting school-based physical activity research. Dr. Walker has assembled a mentorship team of experts in implementation science (Dr. Maria Fernandez, primary mentor), applied statistical methods (Dr. Charles Green, co-mentor), and physical activity research (Drs. Harold Kohl and John Bartholomew, co-mentors). The proposed study sets out to improve the implementation of active learning, which is a school-based evidence-based approach that incorporates physical movement into academic lessons. The study rationale is that active learning approaches are effective for increasing children's physical activity, yet there are large gaps in research about their implementation in practice. The study aims are: 1) develop an implementation strategy to improve the use and sustainment of active learning approaches in elementary schools and 2) conduct a feasibility study to evaluate the impact of the developed implementation strategy on the implementation and effectiveness of active learning. Aim 1 will use Intervention Mapping, a systematic approach to develop a scientifically-based multifaceted implementation strategy. Aim 2 will use a quasi-experimental design to examine acceptability of the implementation strategy and its impact on implementation fidelity. Aim 2 will also examine the preliminary effectiveness of active learning. This study is highly significant because it addresses physical inactivity among children in schools where there is an urgent need for implementation support. If effective, the developed implementation strategy has the potential to improve the use of active learning and reach millions of students across the US. The study is innovative because it targets a novel approach for active learning where there is limited research about implementation strategies to support the use of such approaches. It also uses a novel framework to guide implementation strategy development, and Bayesian statistical methods to determine whether the implementation strategy warrants further testing. Results from this study will enhance the ability to scale-up physical activity approaches in schools. Data will also be used to pursue R01 funding for a larger scale trial, which will further support Dr. Walker's transition to research independence.
