ABSTRACT
This column evaluates the advantages and disadvantages of the use of Webcasts for continuing education, and offers strategies to improve learner outcomes.
Recent advances in Internet applications provide nurse educators with more options for engaging learners in active and accessible continuing nursing education. One recent addition to the repertoire is the Webcast. Webcasts, also known as Webinars, e-conferencing, or Internet videoconferencing, are synchronous meetings using the Internet.
Webcasts require the use of specific but easily accessible hardware and software (Shi & Morrow, 2006). The minimal hardware requirements include a computer with high-speed Internet access and a web browser along with a telephone to dial into the conference (usually by way of a toll-free number). Additional hardware can include a desktop video camera (all participants can then see and hear each other) and a handsfree headset for speaking.
Webcasts require software to organize and manage the conference. The software typically has a text message (chat) function that can be private or public, an audio interface that enables voice communication among participants, and white board and application sharing tools that permit all participants to view and use an application (e.g., viewing a PowerPoint presentation, video, data set, spread sheet, or shared file development using a Word document). There is also a "polling" function in which participants can complete surveys, answer questions, vote, or "raise their hand." Large groups can be divided into subgroups using the chat room function. The archive function allows participants who could not attend to view the session.
Webcast software can be purchased or leased. Commonly used vendors include Elluminate, Macromedia Breeze, and Horizon Wimba. Webcast software may be integrated within a learning management system such as Blackboard/WebCT. Other vendors and software are evaluated at http://www.thinkofit.com/webconf/ realtime. The decision to purchase or lease depends on the frequency of use and size of the authence.
PROS AND CONS OF WEBCASTS
Webcasts are ideal for short educational sessions in which an educator or expert is presenting key information. The educator can use PowerPoint slides to illustrate key points or show a video clip to demonstrate a skill or use of new equipment. Webcasts can also be used with small groups at a participating site. Continuing education...
