Open educational resources (OER), are openly licensed text, media, and other digital and analog assets that are useful for teaching, learning, and research. Recent research has shown that in courses where open textbooks are assigned, students perform as well as or better than students in similar courses with commercially licensed textbooks. Despite cost savings and demonstrated effectiveness, perceptions about quality, relevance, ease of access, and other concerns persist. The objectives of this study were twofold: (a) to develop a practical and reusable measure for evaluating open textbook quality in terms of pedagogy, openness, accessibility, and relevance; and (b) to use the measure to rate the quality and relevance of open textbooks for use in higher education in The Bahamas. The study confirmed the viability of the quality measure as a practical tool to assess open resources and found that the open textbooks studied were accessible and well matched to course content, but of varying quality. More study is needed to explore ways to increase faculty adoption, use, adaption and production of OER.

开放式教科书：巴哈马高中学习的质量和相关性

开放式教育资源（OER）是开放式许可的文本，媒体以及其他对教学，学习和研究有用的数字和模拟资产。最近的研究表明，在分配公开课本的课程中，学生的表现要好于拥有商业许可课本的类似课程的学生。尽管节省了成本并表现出有效性，但人们仍然对质量，相关性，易用性和其他担忧保持着看法。这项研究的目标是双重的：（a）制定一种实用且可重复使用的措施，以从教学法，开放性，可及性和相关性方面评估公开课本的质量；（b）使用该措施对巴哈马高等教育中公开课本的质量和相关性进行评估。该研究证实了质量度量作为评估开放资源的实用工具的可行性，并发现所研究的开放教科书易于获取，并且与课程内容完全匹配，但质量不同。需要更多的研究来探索增加教师对OER的采用，使用，适应和生产的方法。
