Design-based Implementation Research (DBIR) is an iterative approach to developing practical theory and tools to solve problems of practice and to support innovation in improving teaching and learning, which is rarely used in informal settings such as libraries. This study presents findings from a multi-year researcher-practitioner collaboration in which the authors employed DBIR to iteratively design and implement a professional development resource, the ConnectedLib Toolkit, for use in public libraries across the United States (U.S.). In this study, the authors explain what established DBIR challenges and benefits in K-12 formal educational contexts manifest in the development and implementation of a professional development resource for youth-serving library staff working in diverse public libraries across the U.S. This study also disentangles how these challenges and benefits manifest in this setting. These insights will be useful to researchers and library practitioners who are considering partnerships to address problems of practice in library systems.

基于设计的实施研究（DBIR）是一种迭代方法，用于开发实用的理论和工具来解决实践问题并支持创新以改进教学，这在非正式环境（例如图书馆）中很少使用。这项研究提出了多年研究人员与从业人员合作的结果，在该合作中，作者使用DBIR来迭代设计和实施专业开发资源ConnectedLib Toolkit，以供在美国（US）的公共图书馆中使用。在这项研究中，作者解释了在K-12正规教育背景下已建立的DBIR挑战和收益在开发和实施针对全美各地公共图书馆中为青年服务的图书馆工作人员的专业发展资源中所体现的内容。这项研究还弄清了在这种情况下这些挑战和好处是如何体现的。这些见解对正在考虑建立合作伙伴关系以解决图书馆系统实践问题的研究人员和图书馆从业人员很有用。
