DigitalChalk

As an xAPI conformant LRS, Watershed can receive data from any xAPI conformant Activity Provider. Many Watershed cards are flexible and you can configure Watershed to display useful visualizations and metrics from almost any xAPI data set. To help you get the most out of your data, we’re working with a number of product vendors to ensure that the data they send is optimized to produce the best possible results in Watershed. We want to help you to configure Watershed cards in the best way possible to display that data.

DigitalChalk is an LMS and Video platform. DigitalChalk is continuing to expand the number of activities tracked with xAPI. Currently video interactions such as playing, pausing and watching are tracked, along with responses to questions and surveys. This guide tells you how to configure DigitalChalk to send data to Watershed and how to configure Watershed to report on the data.

This guide has two sections:

Configuring DigitalChalk to connect to Watershed

To connect DigitalChalk to Watershed you will need xAPI endpoint and credential details. See How do I add an activity provider to Watershed? for details of where to find your endpoint and credentials in Watershed.

Organization Administrators have access to connect their DigitalChalk environment to Watershed.  After logging into DigitalChalk, navigate to the Administration tab and to My Organization.  From there, click on xAPI/TinCan LRS to start the setup.

Click on Add your LRS.

You can name your connection and add your endpoint, key and secret.  Don’t forget to enable the connection when you are ready for DigitalChalk to start sending statements.

Configuring Watershed to report on DigitalChalk data

Surveys are best reported on using the Activity card. Simply create a new Activity card and select the survey you want to report on.

Video metrics are best viewed by creating measures and using them in various measure based cards. Measures you could create include:

Pause, Play and Completion Count

Pause, play and completion count measures can be used to explore usage of videos or activity of learners. They can be created using a simple ‘Verb’ filter and ‘Count’ aggregation as shown below.

Start and End Point

The start and end point measures can be used with the Range card and a timestamp custom dimension to  explore which sections of the video are most commonly watched.

These measures look at the value of a context extension and use the ‘Last’ aggregation. They should also include a verb filter for the verb ‘watched’ (http://activitystrea.ms/schema/1.0/watch).

The timestamp custom dimension must be entered using advanced configuration and the following syntax:

"dimensions": [
  {
    "type": "STATEMENT_PROPERTY",
    "statementProperty": "timestamp"  
  }
]

Pause Position

The pause position measure is identical to the End Point measure except filtered with the verb ‘paused’ (http://id.tincanapi.com/verb/paused). It can be used with the Interaction Count Measure to create a linear scatter chart organized by statement id using the following custom dimension:

"dimensions": [
  {
    "type": "STATEMENT_PROPERTY",
    "statementProperty": "timestamp"  
  }
]
