🤲🏿 😎 👯 xAPI / CMI5. Volle Kraft 🛄 🔼 👨🏽‍🏭

Fahren wir mit der Analyse der xAPI / CMI5-Spezifikationen zum Speichern und Analysieren von Personalschulungsdaten fort. In den letzten Jahren ist eine relativ große Anzahl von Artikeln über die Verwendung der berücksichtigten Spezifikationen erschienen (z. B. https://levellab.ru/blog/xapi-1 ). Bestehende Veröffentlichungen beschreiben jedoch meiner Meinung nach die Verwendung von Spezifikationen sehr oberflächlich. Ja, ich stimme zu, dass die Verwendung von xAPI zum Berichten einer Kursansicht einer Präsentation oder eines Tests eine ziemlich triviale Aufgabe ist. Vor allem, wenn Sie nur Informationen in Form von Zeitaufwand und Schätzungen benötigen. Im vorherigen Artikel habe ich bereits geschrieben, dass die Verwendung von xAPI bei diesem Ansatz meines Erachtens keinen signifikanten Vorteil bietet.

Aus diesem Grund habe ich mich entschlossen, "tiefer zu graben" und zu zeigen, wie Sie die xAPI-Spezifikation bei 100% Leistung verwenden können. nicht nur im Speicher, sondern auch in der Datenanalyse. Darüber hinaus werde ich versuchen , den Unterschied zwischen xAPI und CMI5 im Zusammenhang mit der Formalisierung der Verwendung von xAPI durch CMI5 praktisch zu erklären.

Als Beispiel verwenden wir einen Simulationssimulator zur Schulung des Personals, zum Beispiel https://youtu.be/zewU3JHZCfg

Sehen wir uns nun den Bericht auf dem CMI5 / xAPI-Formular an. Beim Starten unserer Ressource (über ein Plugin für Moodle oder über einen sehr praktischen Service zur Überprüfung) erhalten wir automatisch einen Eintrag im LRS mit dem Verb "http://adlnet.gov/expapi/verbs/launched". Bitte beachten Sie, dass die Aufnahme nicht von unserem Programm mit Ihnen durchgeführt wird, sondern von dem Dienst, der sie startet (z. B. -moodle). Die letzten 4 Datensätze (ID, Berechtigung, gespeichert, Zeitstempel) werden vom LRS selbst gebildet. Auch Informationen zur Registrierung (Registrierung: "fb13ae65-d9cf-469d-8d89-e41fd61c842d"), zum LRS-Endpunkt und zur Autorisierung werden direkt an unsere Ressource übertragen, wodurch es möglich ist, eine Anfrage an LRS zu stellen und den "gestarteten" Datensatz sogar zu finden. Zum Beispiel aus der exe-Datei. Auf diese Weise können wir Informationen über den Auszubildenden, das Team usw. erhalten. Grundsätzlich können wir diese Aufzeichnung selbst durchführen, wenn wir beispielsweise eine exe-Datei ohne LMS-System ausführen.
