BACKGROUND
Incorporating physical movement in the teaching of academic content (active learning) is a promising approach to improve children's health and academic performance. Despite documented benefits, implementation of active learning remains challenging for schools. The aims of this study are to develop an implementation strategy to support the delivery of active learning in elementary schools and examine the impact of the developed implementation strategy on the implementation and effectiveness of active learning.
METHODS
Aim 1 will use Implementation Mapping, which is a multi-step approach that guides the use of theory, stakeholder input, and existing literature to develop a scientifically based implementation strategy for active learning in elementary schools. Aim 2 will feature a feasibility study to examine the impact of the implementation strategy on both implementation and effectiveness outcomes, consistent with a Hybrid Type 2 design. Acceptability and implementation fidelity will be the primary implementation outcomes, and student physical activity levels will be the primary effectiveness outcome. We will recruit two elementary schools within our partner district, and one will be randomly assigned to receive usual support while the other will receive the newly developed implementation strategy. Participants from each school will complete baseline, 6-, and 12-month assessments. Bayesian statistical approaches will quantitatively examine preliminary effectiveness outcomes. We will also use an embedded mixed methods approach to triangulate findings.
DISCUSSION
This study's innovative overarching conceptual framework (centered on Implementation Mapping) will inform the development and testing of the implementation strategy. This study also uses methodological approaches optimal for feasibility studies, including mixed methods and Bayesian statistics. As a result, we will be able to gain a thorough understanding about the feasibility and preliminary effectiveness of the implementation strategy, which will inform subsequent research and practice for implementing active learning in schools.

背景
将体育活动融入学术内容教学（主动学习）是改善儿童健康和学业成绩的一种有前景的方法。尽管有已记录的益处，但主动学习的实施对学校来说仍然具有挑战性。本研究的目的是制定一项实施策略，以支持小学开展主动学习，并检验所制定的实施策略对主动学习实施情况和效果的影响。
方法
目标1将使用实施映射法，这是一种多步骤方法，指导运用理论、利益相关者的意见和现有文献，为小学主动学习制定基于科学的实施策略。目标2将开展一项可行性研究，以检验实施策略对实施结果和效果结果的影响，符合混合2型设计。可接受性和实施保真度将是主要的实施结果，学生的身体活动水平将是主要的效果结果。我们将在我们的合作学区内招募两所小学，其中一所将被随机分配接受常规支持，而另一所将接受新制定的实施策略。每所学校的参与者将完成基线、6个月和12个月的评估。贝叶斯统计方法将定量检验初步效果结果。我们还将使用嵌入式混合方法对研究结果进行三角验证。
讨论
本研究创新的总体概念框架（以实施映射为中心）将为实施策略的制定和测试提供信息。本研究还采用了最适合可行性研究的方法，包括混合方法和贝叶斯统计。因此，我们将能够全面了解实施策略的可行性和初步效果，这将为随后在学校实施主动学习的研究和实践提供信息。
