The EchoCenter provides a variety of statistical data to help you understand overall viewing patterns and students’ level of interaction with specific lecture recordings. How are these statistics generated and what do they mean? More importantly, how can you use this information to improve your teaching efforts?

echocenter-help-iconNote: The following information was drawn from the Echo360 document Teaching Aids – What Did Students Watch?, which is available through the Help icon in the upper right corner of the EchoCenter screen.

Course Statistics

The course statistics graphically shows you the number of views by specific Echo recording and by week.

Select the View Trends By Echo option in the drop-down list to see how many times an Echo recording was viewed and the number of unique viewers. In the bar chart below, we see that the Echoes of April 17 (4/17) and April 30 (4/30) had far more viewers than typical. There may be discussion questions in these Echoes that are worth reviewing.

Select the View Trends By Week option in the drop-down list to see how many Echo recordings were viewed by week and  the number of unique viewers. You will probably see an upsurge in viewing the week before an exam.

You can glean additional information from these charts by maniplating these bar charts:echocenter-hover

  • See details. Hover over a bar to see a pop-up with details about the number of views, as shown on the right.  
  • Focus  on a particular part of the chart by clicking on it and dragging to zoom, revealing additional detail. Double-click to restore the normal view.
  • See earlier and later dates. Click the arrows on the left or right side of the chart to scroll the area displayed.


 
Viewing Analytics

Viewing analytics present quantitative date for a particular Echo recording.

Average Completion helps you gauge the level of student viewing of this Echo recording relative to other recordings in the course. Say that student A watches the entire Echo (every scene), generating a completion rate of 100%. Student B watches only half of the scenes, generating a completion rate of 50%. If no other students watch the Echo, the Average Completion is 75%. You might want to keep an eye on this parameter to see if the completion rate for a particular lecture recording is very high or very low.

Engagement Analytics

Engagement analytics give you a quantitative view of student interest in a particular Echo recording, based on the level of activity in related online discussions.

Notice that the screen image above, the Echo recording selected generated four discussion topics with six replies.This means a total of six replies among the four topics. One topic could have generated all six.

echocenter-discussion-iconTo display the discussion topics and related replies, select the Discussion tab .


 
Usage Heat Maps

Heat maps illustrate student reaction to an Echo recording. A color-coded line shows what segments of an Echo students found most interesting (“hot spots”), somewhat interesting (“warm spots”), and less interesting. Clicking on the heat map opens the Echo to that segment.

The EchoCenter determines the “heat quotient” of a segment by analyzing:

  • The number of views received by a segment
  • The number and intensity of discussions generated by a segment
  • The number of notes generated by a segment

The text below the map calls out the number of hot and warm spots (left screen image).

When you hover your cursor over parts of the heat map (right screen image), a yellow tooltip:

  • Indicates the segment in the Echo. In the example below, the cursor is over minute 19, second 0 of the Echo.
  • Interprets the color. In the example below, the cursor is over an orange portion of the heat map so the tooltip indicates that the segment is “warm”.
