BACKGROUND
The advent of newer technology and students' growing familiarity with it has enabled information providers to introduce newer teaching methods such as audio podcasting in education. Inclusion of audio podcasts as a teaching aid for undergraduate medical or dental students could serve as a useful supplement to make reviewing more convenient and to enhance understanding and recall of the subject matter.
AIMS
To assess the efficacy of podcasts as a supplementary teaching and learning aid for first-year dental students of Manipal.To study students' attitudes towards audio podcasts and perceived utility of podcasts.
METHOD
This study was conducted at the Manipal College of Dental Sciences, India. The participants were first-year dental students. Live lecture classes were conducted for the students (n=80). The students were then divided randomly into two equal groups of 40 each. Group 1 students (n=40) had a study session followed by a multiple choice question (MCQ) test. This was followed by a podcasting session. Group 2 students had a study session along with an opportunity to listen to a podcast, followed by the test. Following this both groups completed a feedback form intended to assess their perceived utility and attitude towards podcasts. The performance score was analysed using SPSS and an independent sample t test was used to test the significance of differences in the mean score between the two groups.
RESULTS
Our analysis revealed a significant difference (p = 0.000) in the mean score between the two groups. Group 1 scored a mean of 7.95 out of 13 and group 2 scored a mean of 6.05 out of 13. Analysis of the feedback forms showed that 91.3 per cent of the students found the podcasts useful, as they could listen to lecture content repeatedly and at their own convenience. Sixty-three per cent of the students, however, felt that the absence of images and diagrams in podcasts was a disadvantage.
CONCLUSION
Students benefited when podcasts were used to supplement live lectures and textbook content. This was indicated by better student performance in the podcast group. Also, students showed a favourable attitude for podcasts being used as a supplementary teaching and learning aid.
背景
新技术的出现以及学生对其日益熟悉，使得信息提供者能够在教育中引入诸如音频播客等新的教学方法。将音频播客作为本科医学生或牙科学生的教学辅助工具，可作为一种有用的补充，使复习更便捷，并增强对学科内容的理解和记忆。
目的
评估播客作为印度马尼帕尔大学一年级牙科学生辅助教学和学习工具的效果。研究学生对音频播客的态度以及对播客实用性的认知。
方法
本研究在印度马尼帕尔牙科学院进行。参与者为一年级牙科学生。为学生们进行了现场讲座课程（n = 80）。然后将学生随机分为两组，每组40人。第一组学生（n = 40）先进行学习课程，随后进行多项选择题（MCQ）测试。之后进行播客课程。第二组学生进行学习课程并同时有机会收听播客，随后进行测试。在此之后，两组学生都完成一份反馈表，旨在评估他们对播客实用性的认知以及对播客的态度。使用SPSS分析成绩得分，并使用独立样本t检验来检验两组平均分差异的显著性。
结果
我们的分析显示两组平均分存在显著差异（p = 0.000）。第一组在满分13分中平均得分为7.95分，第二组平均得分为6.05分。对反馈表的分析表明，91.3%的学生认为播客有用，因为他们可以根据自己的方便反复收听讲座内容。然而，63%的学生认为播客中缺少图像和图表是一个缺点。
结论
当使用播客来补充现场讲座和教科书内容时，学生受益。这通过播客组学生更好地表现得以体现。此外，学生对将播客用作辅助教学和学习工具表现出积极态度。
