MIND has finished two years of operation as a regional center for continuing dental education. The responses from viewing cards, and the number of credit hours given, indicate that approximately 20% of the potential audience participated in the course offerings. Previous experience from a two-year study in South Dakota has shown that there are three major factors that are essential for effective use of television as a dissemination medium. These are as follows: 1) the program should establish effective use of the communication system to maintain an audience; 2) the quality of thr programming material that is televised must be high; 3) the program should be televised on a regular basis to develop viewer habits or expectations. With a potential audience of 11,000 persons, MIND has had to depend heavily on a bulk-rate mailing system to communicate with members of the dental profession. This has caused problems such as reminders not being received on time, or being lost in the mail, or not being read, so that the individual is unaware that the courses are being telecast. Another problem of mailing system is maintaining an up-to-date list of addresses. The names and addresses of the dental assistants are impossible to keep up to date. We use the lists of licensed dentists and dental hygienists issued each July and a list of the certified dental assistants, which, of course, does not include all the dental assistants in our five-state area. A system providing more direct contact with the individual needs to be developed. Quality of televised courses is determined by the clinician's style of presentation as well as by the content and organization of the course material. The selection of dental information aimed toward the dentist in general practice results in loss of some members of the viewing audience, particularly specialists and generalpractitioners who have confined their practice to a particular area of dentistry. Quality is also judged by the technical aspects such as camera coverage, color, types of audiovisual materials, and televison reception. There is a limited amount of videotaped material available, and the members of the Board of Directors are asked to preview the videotapes and select three courses that they judge to be of the best quality for the year's programs. One difficulty is to find courses that will be of value to all three groups--dentists, dental assistants, and dental hygienists. Despite the problems encountered, the use of educational television should focus on the positive characteristics of availability, relatively low cost of operation, and the opportunity to provide continuing dental education at a convenient time and place.
MIND作为一个区域性的继续牙科教育中心已运营两年。观看卡片的反馈以及所授予的学分小时数表明,大约20%的潜在受众参加了课程。南达科他州一项为期两年的研究的先前经验表明,有效利用电视作为传播媒介有三个主要因素。具体如下:1)该节目应有效利用传播系统以维持受众群体;2)所播放的节目材料质量必须很高;3)该节目应定期播放以培养观众的习惯或期望。MIND的潜在受众有11000人,因此不得不严重依赖批量邮寄系统与牙科专业人员进行沟通。这引发了一些问题,比如提醒未按时收到、在邮寄过程中丢失或未被阅读,以至于个人不知道课程正在播出。邮寄系统的另一个问题是保持地址列表的最新状态。牙科助理的姓名和地址很难保持最新。我们使用每年7月发布的持牌牙医和牙科保健员名单以及注册牙科助理名单,当然,这并不包括我们五州地区的所有牙科助理。需要开发一种能与个人进行更直接联系的系统。电视课程的质量取决于临床医生的授课风格以及课程材料的内容和组织。针对一般执业牙医选择牙科信息会导致部分观众流失,尤其是那些将业务局限于特定牙科领域的专科医生和全科医生。质量还由诸如镜头覆盖、色彩、视听材料类型和电视接收等技术方面来评判。可用的录像材料数量有限,董事会成员被要求预览录像带并挑选出他们认为是当年节目中质量最佳的三门课程。一个难题是找到对牙医、牙科助理和牙科保健员这三个群体都有价值的课程。尽管遇到了这些问题,但教育电视的使用应关注其可用性、运营成本相对较低以及能在方便的时间和地点提供继续牙科教育等积极特性。
