	abstract = {<p>In diesem Beitrag pr{\"a}sentieren wir eine generische und erweiterbare Analyseworkbench und zeigen, wie sie mit verschiedenen Lernplattformen integriert werden kann, um die Aktivit{\"a}ten auf der Plattform zu analysieren. Da die Workbench bereits ein breites Spektrum von Analysen abdeckt, beschr{\"a}nkt sich der Integrationsaufwand auf das Bereitstellen von Import- und Exportfunktionen, um die zu analysierenden Daten und die Analyseergebnisse zwischen Lernplattform und Analyseworkbench zu transportieren. Die Workbench erlaubt zudem eine einfache Erg{\"a}nzung um weitere, speziellere Analysen, sollten diese gew{\"u}nscht sein. Anhand von drei Beispielen pr{\"a}sentieren wir einen allgemeinen Ansatz zur Integration der Analyseworkbench mit Lernplattformen.</p>
