Purpose The purpose of this paper is to introduce a survey instrument to measure three components of students’ perceptions of open and affordable course materials – quality, integration, and experience – and discuss its reliability and predictive validity. Design/methodology/approach The authors distributed an end-of-semester online survey to students enrolled in sections of 12 courses that adopted OER in Fall 2016, as well as conducting a within-interview survey with the instructors of those courses. The authors calculated the descriptive statistics from the responses to the student survey, as well as examining the inter-item and inter-rater reliability of the instrument. Finally, explored correlations in the data gathered through both the student and faculty surveys were explored. Findings The authors found that both students and faculty were generally pleased with the quality and experience of using open and affordable digital materials. The authors also found that our three survey subscales had strong inter-item reliability, and that the quality and experience subscales had predictive validity in terms of whether students would choose a traditional or digital text in future courses. Originality/value In addition to providing evidence in terms of the full survey instrument’s reliability and predictive validity, factor analysis indicates that a short scale of quality and experience Likert scale items could be used by practitioners to effectively assess satisfaction of digital materials among traditionally aged undergraduate students.

了解学生对OER作为课程材料的满意度

目的本文的目的是介绍一种调查工具，以测量学生对开放和负担得起的课程材料的看法的三个组成部分–质量，整合性和经验–并讨论其可靠性和预测有效性。设计/方法论/方法作者向在2016年秋季采用OER的12门课程的部分入学学生分发了期末在线调查，并与这些课程的指导者进行了面试。作者根据对学生调查的回答计算了描述性统计数据，并检查了仪器的项目间和评分者之间的可靠性。最后，探讨了通过学生和教职员工调查收集的数据中的探索相关性。结果作者发现，使用开放和负担得起的数字资料的质量和经验使学生和教师普遍感到满意。作者还发现，我们的三个调查子量表在项目间具有很高的信度，并且质量和经验子量表在学生将来会选择传统还是数字文本方面都具有预测效度。独创性/价值除了提供全面调查工具的可靠性和预测效度方面的证据外，因素分析还表明，从业人员可以使用李克特量表的质量和经验水平较短，以有效评估传统年龄的大学生对数字资料的满意度学生。
