Which distance learning method allows multiple classroom locations to view and hear a presentation simultaneously?

The correct choice is videoconferencing because this method enables real-time audio and video communication in a multi-location setup. Participants in different classrooms can see and hear the same presentation simultaneously, fostering interactive discussions and allowing for shared learning experiences, much like being in the same physical room. This technology connects various sites through digital means, helping to overcome geographical barriers associated with traditional classroom settings.

In contrast, audio conferencing only transmits sound without the visual component, limiting the ability for participants to engage with visual materials or observe presenters. Computer-based training usually involves self-paced learning through software without live interaction, and online learning typically refers to courses conducted primarily over the internet, which may not include the synchronous interaction possible in videoconferencing. Thus, videoconferencing stands out as the method that best meets the criteria described in the question.
