The accuracy of this is highly dependent on the length of the presentation. The EchoPlayer does not send data up to HEMS on every segment viewed. It accumulates them and sends data on timed intervals just like google analytics does. The timed interval is dependent on the length of the presentation. For presentations less than 50 minutes, it only sends data once every 1.5 minutes, with segments at 15-second intervals. So let's say, the presentation is only 2 minutes long and the user views the 2 minutes and then closes the browser. In this case, only the first set of stat data would be sent by the EchoPlayer and therefore, even though the user watched the entire presentation, the second chunk of data was never sent and EchoCenter will only see about 50% of the presentation as viewed.

Think Before You Conclude. If a student shows low numbers for the first six parameters listed (Unique Views, Cumulative Views, Completion, Last Viewed, and Date Viewed), you might conclude that she is not engaged. Before drawing that conclusion, look at the Downloads parameter. A student may have downloaded many Echoes and be diligently viewing them, but these activities will not be reflected in the first six parameters. Is the Student Using a Mobile Device? If usage information is not appearing at all for a student, or minimal usage information appears, find out how the student is consuming the Echoes. The EchoSystem collaboration service is not able to collect information from mobile players at this time, so those views are not being tracked. This is slated to be addressed in a future release. Why is the Data Skewed Like That? When a student views an Echo via the full EchoPlayer (via desktop or laptop), the EchoSystem Server (ESS) can collect the parameters listed above. When a student downloads anEcho, or views an Echo from a mobile device (phone or tablet), communication with the ESS is hindered and no such data can be collected. Because it is not collected, the parameters for the student are low. Therefore. Consider the Downloads parameter and mobile viewing possibility before drawing conclusions about a student's engagement. |
