Our objective was evaluate the effectiveness and acceptability of 3 methods of instructor interaction during distance learning with prerecorded seminars in orthodontic residencies and continuing education.
After residents at 3 schools (Sydney, Australia; Winnipeg, Manitoba, Canada; and Manchester, United Kingdom) viewed a recorded interactive seminar, they discussed its content with the seminar leader at a distance via video conferencing, audio-only interaction by telephone, and Internet chat with Net Meeting software (Microsoft, Bellevue, Wash). The residents then completed evaluations containing both closed- and open-ended questions. In addition, attendees at the Iranian Orthodontic Congress also viewed a recorded seminar, had questions answered via an interpreter in a video conference, and completed summary evaluations.
Video conferencing received the highest ratings and was never cited as the least favorite method of interaction. Telephone interaction was a close second in mean scores, and Internet chat was a distant third. All residents stated that they would like to be taught through distance education again. However, the Iranian orthodontists were less enthusiastic.
Distance learning based on observation of recorded seminars and follow-up interaction is an acceptable method of instruction that can allow residents and practicing orthodontists access to various materials and experts, and perhaps help to ease the strains of current faculty shortages. More data are needed to determine whether video conferencing is worth the additional cost and complexity over audio-only interaction.
我们的目标是评估在正畸住院医师培训和继续教育中,通过预先录制的研讨会进行远程学习时三种教师互动方法的有效性和可接受性。
来自三所学校(澳大利亚悉尼、加拿大曼尼托巴省温尼伯和英国曼彻斯特)的住院医师观看了一场录制好的互动研讨会后,他们通过视频会议、电话纯音频互动以及使用Net Meeting软件(微软公司,华盛顿州贝尔维尤)进行互联网聊天,与研讨会负责人远程讨论其内容。住院医师随后完成了包含封闭式和开放式问题的评估。此外,伊朗正畸大会的参会者也观看了一场录制好的研讨会,通过视频会议中的口译员解答问题,并完成了总结评估。
视频会议获得了最高评分,且从未被列为最不受欢迎的互动方式。电话互动的平均得分紧随其后,互联网聊天则远远落后位居第三。所有住院医师均表示他们愿意再次接受远程教育。然而,伊朗正畸医生的热情较低。
基于观看录制好的研讨会及后续互动的远程学习是一种可接受的教学方法,它能让住院医师和正畸执业医生获取各种资料并接触到不同专家,或许还有助于缓解当前师资短缺的压力。需要更多数据来确定视频会议相较于纯音频互动,额外的成本和复杂性是否物有所值。
