Short for web-based seminar, a presentation, lecture, workshop, or seminar that is transmitted over the Web. A key feature of a webinar is its interactive elements - the ability to give, receive and discuss information (definition adapted from Webopedia). A webinar is a seminar or workshop which is held online using video conferencing software. Webinars are often held in virtual classrooms but can also be held using other video conferencing tools. Presenters and attendees at a webinar will join online, synchronously from wherever they are. Webinars are usually interactive, not just a lecture with Q&A. The different tools provided by virtual classroom software enables student engagement in webinars e.g., by text chat, answering polls, engaging in activities, asking questions, or discussion and activities in breakout rooms.
