Thread "ExtendedTestStatistics Plugin"

Hello Fred,

thank you for the great plugin! Great work!

This will be an enrichment for testing with ILIAS and our testers will be excited. A great step for an extensive quality management of tests.

I have tested the plugin with some tests which are already done in the past. We have many tests with a number of participiants > 500, up to 1500. Even the number of used question varies up to 200 questions in one test. If I understood the function of the plugin correctly, the statistics are generated with clicking on the register "aggregated testresults" ...

Is it possible to implement a kind of "caching the statistic data" with the collected data of the first run (time stamp of the last run), and implement a button (e.g.) "refresh data" to generate the statistics on demand?!

Currently a click on the appropriate tabs takes many minutes or it runs into a timeout. Especially for the tab aggregated results for questions. So each click on the tab results in "waiting ... waiting ... waiting" or timeout.

Best regards,

Mark

Hi Mark,

thanks for your feedback. The performance is on our list of open issues. I tried to optimize the calculations in the plugin as far as possible, e.g. by separating the test statistics from question statistics and by calculating the additional question evaluations only for those questions that are displayed on a page. But this is not enough. I see two solutions with potential:

• The plugin is built on the output of ilObjTest::getUnfilteredEvaluationData() which seems not do be very performant for large tests. I could improve this by directly querying the raw table data but this won't be clean and would make updates difficult.
• We already discussed the caching possibility on the last SIG EA meeting. We have to ensure that the cache gets invalid when test results are changed. A "Refresh" button may help, but the plugin must be aware that the refresh is needed and show at least a warning if the cache is outdated. Björn proposed to fire an event in that case, but unfortunately the UI plugins are not able to listen to events. As a workaround we could look in the result tables of the test object for the highest timestamp and compare it with the timestamp of the statistics cache.

Best regards

Hi Fred,

just off topic:

 Wouldn't this be an important feature request for 5.3? If so, please create a feature request until tonight. Otherwise, it will take until 5.4 to get this feature.

Kind regards,

Matthias
