Multisite research (MSR) offers the key advantages of greater statistical power and external validity via larger and more diverse participant pools. In second language acquisition (SLA) research, recent developments in meta‐analysis have created a robust foundation for MSR. Although logistical and financial obstacles can complicate expansion beyond a single site, we show that MSR's benefits can justify the investment of resources. We begin by outlining how developments in meta‐analytic research, replication, and access to data and materials have created an especially opportune moment for MSR. Next, we discuss the methodology for a classroom study on metacognitive instruction as an illustrative case, outlining the major elements of its design and implementation. Finally, we review how four issues critical to MSRs (funding, compliance, logistics, and analysis) were addressed in our example study, including a discussion on multilevel modeling. We conclude with a discussion of how the field can build upon existing research to advance multisite work.

多站点第二语言习得研究的案例：挑战，风险和奖励

多站点研究（MSR）通过更大和更多样化的参与者库提供了更大的统计能力和外部有效性的关键优势。在第二语言习得（SLA）研究中，荟萃分析的最新发展为MSR奠定了坚实的基础。尽管后勤和财务障碍可能会使扩展到单个站点之外的事情变得复杂，但我们证明了MSR的好处可以证明资源投资的合理性。我们首先概述了元分析研究，复制以及对数据和材料的访问的发展如何为MSR创造了特别有利的时刻。接下来，我们讨论以元认知教学为例的课堂研究方法，作为案例，概述其设计和实现的主要内容。最后，我们回顾了对MSR至关重要的四个问题（资金，合规性，物流，和分析）在我们的示例研究中得到了解决，包括有关多级建模的讨论。最后，我们讨论了该领域如何在现有研究的基础上推进多站点工作。
