How might a professor use an LMS to keep track of attendance in a class that is held face to face?

a. At the beginning of each class period, students are required to use clickers to take a brief multiple-choice test to indicate they are present.

b. An instructor uses a sheet of paper to take attendance but transfers that information to the LMS after the class time is over.

c. Students ask questions using the chat feature of the LMS rather than raising their hands in class.

d. Students are required to bring their own device to class to view the lecture PowerPoints on the LMS instead of the professor projecting them onto a smartboard.
