Hi Jhonn Marie
I'm not an IT specialist, but I'm fascinated with Xerte and in the past I have been asked to provide some way of tracking how long learners spend on XOT pages.
One way this can be done is through the Results page
xerte.org.uk/wiki/doku.php?id=3.13_results_page . This certainly tracks the duration a scorable Interactivity page is open, but I am not sure whether this can be done for all pages in a project including for example Text and Media pages.
The Results page provides feedback to the learner, not the instructor. You could ask learners to download their Resullts page and upload it to some kind of portfolio accessible to instructors, but woutd have to trust learners not to alter the records during the process.
In my experience (I'm retired now) educational managers like metrics, because they help them measure progress towards goals, or make/justify decisions. In the case of time spent with a webapage open, when learners are working independently outside the physical classroom, there is no practical way of knowing whether they are attending to the XOT page, chatting with a friend or doing something on social media. If learners know this metric is being tracked, and why, then it's fairly easy for them to game the system. There's a cost to any kind of activity, whether it's economic or educational, and I'm not sure that tracking time spent with a page open provides sufficient benefits to make it worthwhile. However, the beautiful thing about XOT is that you can choose whether or not to track.
Best wishes
