Because a traditionally instructed dental radiology lecture course is very time-consuming and labour-intensive, online courseware, including an interactive-learning module, was implemented to support the lectures. The purpose of this study was to evaluate the perceptions of students who have worked with web-based courseware as well as the effect on their results in final examinations.
Users (n(3+4)=138) had access to the e-program from any networked computer at any time. Two groups (n(3)=71, n(4)=67) had to pass a final exam after using the e-course. Results were compared with two groups (n(1)=42, n(2)=48) who had studied the same content by attending traditional lectures. In addition a survey of the students was statistically evaluated.
Most of the respondents reported a positive attitude towards e-learning and would have appreciated more access to computer-assisted instruction. Two years after initiating the e-course the failure rate in the final examination dropped significantly, from 40% to less than 2%.
The very positive response to the e-program and improved test scores demonstrated the effectiveness of our e-course as a learning aid. Interactive modules in step with clinical practice provided learning that is not achieved by traditional teaching methods alone. To what extent staff savings are possible is part of a further study.
由于传统的牙科放射学讲座课程非常耗时且劳动强度大,因此开发了在线课件,包括一个互动学习模块,以支持讲座。本研究的目的是评估使用基于网络的课件的学生的看法,以及对他们期末考试成绩的影响。
用户(n(3+4)=138)可以在任何联网的计算机上随时访问电子课程。两组(n(3)=71,n(4)=67)在使用电子课程后必须通过期末考试。结果与两组(n(1)=42,n(2)=48)进行了比较,这两组通过传统讲座学习了相同的内容。此外,对学生进行了调查,并进行了统计学评估。
大多数受访者对电子学习持积极态度,如果有更多机会接受计算机辅助教学,他们会感到满意。在启动电子课程两年后,期末考试的不及格率从 40%显著下降到 2%以下。
对电子课程的积极响应和考试成绩的提高证明了我们的电子课程作为一种学习辅助工具的有效性。与临床实践同步的互动模块提供了传统教学方法无法实现的学习。节省员工的程度是进一步研究的一部分。
