Business Objectives

Buck Studios, through Sherry Matthews Group, developed several dozen online courseware modules related to nutrition, childcare, and parenting. These modules are offered through the Texas Women, Infants and Children online programs. The vendor selected xAPI as a data tracking solution, in order to provide more robust and fine grained metrics about course performance and assessment responses. The vendor initially tracked data to another (non-Veracity) LRS system, but found significant scalability issues resulting in hung courses and learners unable to access content. This issue manifested itself after a few weeks of operation, when data loads approached 1 million xAPI statements.

Approach

Veracity was selected to install and configure a system capable of servicing thousands of course completion each day, and provide data metrics and analytic insights in real time. Additionally, Veracity would be responsible for allocating and provisioning AWS resources in the customers name to support the expected load. Veracity would also implement a custom report showing weekly question responses and content use across all classes and cohorts.

Outcome

As of June 2020, this case study has generated over 66 million xAPI Statements. The system continues to track several thousand courses each day, with 99.98% uptime. Data reports are used to continuously refine the learning content.

The Solution

Veracity added the ElasticSearch based analytics integration, and deployed this solution within weeks of contract award. This software feature allowed Veracity to display interactive metrics in real time over large amounts of data. These features proved so successful that they have since been integrated into the core product, and continue to serve the WIC program. Veracity also designed the customer hosted IT infrastructure for high throughput and high availability. The final solution involved a network of 7 servers in 3 domains, with complex security and availability configurations.
