What tool did Mr. Davidson create to facilitate student feedback during presentations?

Mr. Davidson created a backchannel discussion using Today's Meet to facilitate student feedback during presentations. This tool allows students to engage in real-time discussions while a presentation is ongoing, providing them with a platform to share their thoughts, ask questions, and offer feedback without interrupting the speaker.

Today's Meet is designed to create a temporary chat room that can be accessed by all students, fostering an environment where interaction is encouraged. This approach encourages participation from all students, including those who may be hesitant to speak up during a live presentation. By using a backchannel, Mr. Davidson enhances student engagement and ensures that feedback is collected in a timely and organized manner.

The other options, while potentially useful for communication, do not specifically address the need for real-time feedback during presentations in the same interactive and organized manner as a backchannel discussion does.
