Introduction

What is the impact of Learning Analytics Beta version?

We have released Learning Analytics in Beta to gain targeted experience within data usage in combination with all the different test types that are possible to create within Inspera Assessment. There are also a few notable items in the current version:

  • Older tests can have missing or less accurate calculation of time spent per question, this and derived values could therefore be wrong.
  • The usage of advanced scoring rules, such as negative marks, marks per alternative, threshold values on questions, and bands and criteria, can affect the values in such a way that they can be hard to interpret.
  • Questions with manual scoring, can be left unmarked by a marker. In these cases, values as average score, P-value and correlation will not be correct.

The best approach for solving the above-listed issues, is something we want to investigate further before a general release. 

 

Question analytics

To access the Analytics: In the menu header, hover over the Author drop-down and click Questions. In the Questions page, navigate to the left side Default Views menu and click Analytics.

Below is a list of all available Learning Analytics-data for each question in a test:

Variable

Description

Attempted

The number of students who answered the question.

Avg. time spent

The average number of seconds spent on the question among the students who have seen the question.

Avg. score

The average score on the question among the students who submitted this test.

Correct 

The number of students who answered the question correctly.

Correlation

A number between -1 and 1. The correlation is the extent to which the question score correlates to the total score. Negative or very low positive values ​​may indicate that the question does not discriminate (differ) well between students of high and low ability. See here for additional documentation: http://https://en.wikipedia.org/wiki/Point-biserial_correlation_coefficient.

Exposed

The number of students, among those who submitted this test, who opened the question. Equals the sum of "Attempted" and "Omitted".

Max score

The maximum score on the question.

Not exposed

The number of students who did not open the question.

Omitted

The number of students who opened the question without answering it.

P-value

The P-value is the normalized average score on a question. This means that the maximum value of the P-value is 1, which happens if all the candidates answer the question correctly. It is worth noticing that the P-value can differ from the average score, even if the question has a maximum score of 1 because the P-value only takes into account the number of candidates that were exposed to the question.

Question order

The position of the question in this test.

 Note: If you use advanced scoring rules with negative scores, it may be difficult to interpret this value.

 

Question usage across test

The stats in the table view are per test only. To filter on a particular test, you know the question has been used in, use the list filter and filter on the name of the test mceclip2.png
If the same question has been used across several test events the stats will be replaced by "Multiple
Values". To look at all the tests the question has been used in, under Question No., click Multiple values and a list of all the test-IDs will be shown.

      1. Copy the ID in parenthesis and open the URL:
        • https://<subdomain>.inspera.no/admin#deliver-test/<question ID here>
      2. This will open the test where the question was used. It is then possible to filter on that test to get the results from that particular test.

Ex. https://demo.inspera.no/admin#deliver-test/23099404
