Here’s a quick (6 minute) video by National Trail Local Schools that highlights one of the reports in Moodle that allows you to drill down to see what students have accessed a specific resource in your online classroom. A simple and easy way to get a short list of students to contact with an additional friendly reminder. (In Moodle 2+ it’s actually located as a link in your Navigation block, not the course settings as shown in the video which highlights 1.9 or before.)
