Scoring system for digital assessment quality with harmonic averaging

A system comprising:

• a computer processor;
• at least one data store in electronic communication with the computer processor that stores assessment data and content health scores;
• and
• a computer memory in electronic communication with the computer processor and configured to store computer-readable instructions which, when executed by the computer processor cause the computer processor to:
• receive a request from a client device in electronic communication with the computer processor, the request defining a content element;
• in response to the request, generate a content analytics interface corresponding to the content element by:
• identifying subcontent elements of the content element;
• retrieving subcontent health scores from the at least one data store;
• and
• generating a table that includes identifying information for each of the subcontent elements and that includes the subcontent health scores, the content analytics interface comprising the table;
• cause the content analytics interface to be displayed at the client device;
• and
• calculate a subcontent health score of the subcontent health scores corresponding to a subcontent element of the subcontent elements by:
• retrieving the assessment data from the data store;
• determining metric values for a plurality of metrics for the subcontent element based on responses submitted to one or more assessment item parts of the subcontent element by a sample population of responders, the plurality of metrics corresponding to a hierarchical content level of the subcontent element, wherein at least one metric value of the metric values is determined by performing weighted harmonic averaging of the subcontent health scores of the subcontent elements of the content element;
• determining metric scores for the plurality of metrics based on the metric values;
• assigning weight values to each of the plurality of metrics for the subcontent element;
• determining reliability values for each of the plurality of metrics for the subcontent element;
• and
• determining the subcontent health score for the subcontent element based on the metric scores, the weight values, and the reliability values.

A method comprising:

• retrieving assessment data from a source database, the assessment data corresponding to a plurality of digital assessment items comprising a plurality of assessment item parts;
• determining first content health scores for each of a plurality of subcontent elements of a content element, the plurality of subcontent elements corresponding to a first hierarchical content level and the content element corresponding to a second hierarchical content level, wherein determining a first content health score for a first subcontent element of the plurality of subcontent elements comprises:
• determining first metric values for a plurality of first metrics for the first subcontent element based on responses submitted to the plurality of assessment item parts by a sample population of responders, wherein at least one metric value of the first metric values is determined by performing weighted harmonic averaging of the first content health scores of the subcontent elements of the content element;
• determining first metric scores for each of the first metrics based on the first metric values;
• assigning first weight values to each of the first metrics;
• determining first reliability values for each of the first metrics based on at least a size of the sample population of responders;
• and
• determining a first content health score of the first content health scores for the first subcontent element based on the first metric scores, the first weight values, and the first reliability values;
• receiving, from a client device, a request for a content analytics interface corresponding to the content element;
• generating the content analytics interface, the content analytics interface comprising a listing of the subcontent elements and the first content health scores corresponding to the subcontent elements;
• and
• causing the content analytics interface to be displayed at the client device.
