Metadata Enrichment of an Exercise and See Mastery Bullets Update

This tasks explains how to enrich the trivial interactive exercise with metadata so that the successful result provokes a mastery boost indicated by the mastery-bullets.

Prerequisite:

• add a trivial interactive exercise
• applications-on: jEditOQMath, ActiveMath, web-browser

Task steps

• we continue based on add a trivial interactive exercise where the exercise mini-exo in the file first.oqmath was being edited
• first verify that the for attribute of our exercise element is correctly written, e.g., that no Unresolved reference appears there
• locate your cursor just below <metadata> and before </metadata> and add the <extradata> element
• inside extradata type <, c, o, choose competency, tick self-closing, press return. Choose a value there, e.g. language
• still inside extradata, type<,c,o, choosecompetencylevel, press return, in the dialog choose a value suchelementaryand tickself-closing-tag`
• still inside extradata type <, d, i return. Choose difficult, tick self-closing tag
• we have now added three essential pedagogical metadata which will serve for the learner-model to associate an exercise result with the mastery of a concept, the concept related to the exercise by the for relation
• invoke a build in AntFarm (as in add a trivial interactive exercise](/?q=en/node/159)), correct any reported errors and re-run if need be
• go to the book’s first page and click Start the exercise
• enter any value in the blank
• see Your exercise is over and close the window with the given button
• this should trigger a reload of the book’s page and table-of-contents
• the latter should now show a changed color aside of My first document (typically green, may depend on the competency and competencylevel you chose)
