This study aims at investigating the effect of response rate and class size interaction on students' evaluation of instructors and the courses offered at heath science colleges in Saudi Arabia.
A retrospective study design was adapted to ascertain Course Evaluation Surveys (CES) conducted at the health science colleges of the University of Dammam [UOD] in the academic year 2013-2014. Accordingly, the CES data which was downloaded from an exclusive online application 'UDQUEST' which includes 337 different courses and 15,264 surveys were utilized in this study. Two-way analysis of variance was utilized to test whether there is any significant interaction between the class size and the response rate on the students' evaluation of courses and instructors.
The study showed that high response rate is required for student evaluation of instructors at Health Science colleges when the class size is small whereas a medium response rate is required for students' evaluation of courses. On the other hand, when the class size is medium, a medium or high response rate is needed for students' evaluation of both instructors and courses.
The results of this study recommend that the administrators of the health science colleges to be aware of the interpretation of students' evaluations of courses and instructors. The study also suggests that the interaction between response rate and class size is a very important factor that needs to be taken into consideration while interpreting the findings of the students' evaluation of instructors and courses.
本研究旨在调查沙特阿拉伯健康科学学院学生对教师及所授课程评价中回应率与班级规模的交互作用影响。
采用回顾性研究设计，以确定达曼大学（UOD）健康科学学院在2013 - 2014学年进行的课程评价调查（CES）。据此，本研究使用了从独家在线应用程序“UDQUEST”下载的CES数据，该数据包含337门不同课程和15264份调查问卷。采用双向方差分析来检验班级规模与回应率在学生对课程和教师评价方面是否存在显著交互作用。
研究表明，当班级规模较小时，健康科学学院学生对教师的评价需要高回应率，而学生对课程的评价需要中等回应率。另一方面，当班级规模为中等时，学生对教师和课程的评价都需要中等或高回应率。
本研究结果建议健康科学学院的管理人员要了解学生对课程和教师评价的解读。该研究还表明，在解读学生对教师和课程评价结果时，回应率与班级规模之间的交互作用是一个非常重要的因素，需要加以考虑。
