ABSTRACT Open Educational Resources (OER) are becoming a significant, mission-driven trend within educational literature. To help address rising costs, instructors and designers are looking to OER to effectively replace traditional instructional content, which requires more than just identify and replace. Drawing from 51 OER studies conducted in countries across the five continents, this systematic literature review explored the empirical themes evident in the current research on a global scale. This review found (1) discoverability, sustainability, and remixing are significant barriers that stand in the way of OER disrupting traditional textbook models; (2) there is no significant difference in learning outcomes when instructors incorporate OER; and (3) implementation of OER as instructional strategies is challenging but can be effective in supporting positive learning outcomes when properly designed. The paper concludes with a discussion of gaps in the literature, considerations for implementation and further directions for future research.

开放的力量：整合开放教育资源的收益，障碍和策略

摘要开放教育资源（OER）在教育文献中正成为一种重要的，以任务为导向的趋势。为了帮助解决不断上涨的成本，教师和设计人员希望OER有效地替代传统的教学内容，而这不仅仅是识别和替换。这项系统的文献综述借鉴了五大洲各国开展的51项OER研究，探索了当前全球范围内研究中显而易见的经验主题。这项审查发现（1）可发现性，可持续性和重新混合是阻碍OER破坏传统教科书模型的重大障碍；（2）当教师采用OER时，学习成果没有显着差异；（3）将OER用作教学策略具有挑战性，但如果设计合理，则可以有效地支持积极的学习成果。本文最后讨论了文献中的空白，实施注意事项和未来研究的进一步方向。
