Which of the following best describes the primary benefit of using Google Hangouts On Air for professional development?

Using Google Hangouts On Air for professional development provides a primary benefit in its ability to record sessions that are shareable on YouTube. This functionality is highly advantageous because it enables educators and professionals to host webinars or training sessions and then easily distribute the recordings to a wider audience. By sharing the sessions on platforms like YouTube, participants who could not attend the live event can watch the recorded content at their convenience. This enhances accessibility and allows for continuous learning as others can benefit from the information presented long after the original session has ended.

Additionally, this recording feature supports various learning styles, as individuals can revisit complex topics and absorb the material at their own pace. This aspect also encourages collaboration and community-building in professional development, as it provides a platform for sharing expertise and insights beyond the confines of a single meeting or location.
