The easiest way to take attendance is to have the students send a message over chat. The chat is saved in a text file automatically after you meeting has ended. The default location for your Zoom folder is in your Documents folder.
Yes. All the students can listen and view presenters and their materials. At minimum everyone would need a microphone to speak. The default meeting setting is for everyone to be able to share their screen, so when each person presents they would share their presentation (powerpoint, google slides, web pages, images, etc). from their device (computer/laptop/phone/tablet). They would only need a camera if they need to be seen. If they are presenting without a camera, you could hear them and would be able to see a shared screen.
Many students may choose to interact using Zoom on a smartphone or other mobile device. Zoom works well on mobile devices. Student would need to go to the app store and download the Zoom Cloud app.
There are 2 methods of recording to the cloud and on your local computer. The benefits of recording to the cloud are that it does not impact the use of your computer, it creates a transcript, and creates a sharable link to share/view. Once the video is processed it can be downloaded and edited and republished elsewhere (YouTube, Mediasite). Overall cloud recording is the recommended method.
Recording to the local computer allows you to edit without waiting for the cloud but you would have to publish to YouTube, Google Drive, OneDrive, Mediasite or other publishing point. Could be preferable if you want to edit your recordings before publishing.
Only hosts and co-hosts can start a cloud recording. If you want a participant to start a recording, you can make them a co-host or use local recording. Recordings started by co-hosts will still appear in the host's recordings in the Zoom web portal. For instructions on how to record, have a look at the bottom of this page:
