Wie lang sollte eine Rollstuhlrampe sein? Ein Modellierungsbeispiel mit Bezug zum Konzept der Steigung in der Sekundarstufe I

Authors

Mathematisches Modellieren stellt ein zentrales Moment eines modernen Mathematikunterrichts dar. Für eine erfolgreiche Unterstützung des Kompetenzaufbaus von Schüler/inne/n bedarf es jedoch Aufgaben, die expliziten Lebensweltbezug aufweisen. Der vorliegende Beitrag stellt eine derartige Aufgabe mit Lebensweltbezug vor, die − aus fachlicher Sicht − inhaltlich mit dem Konzept der Steigung in Verbindung steht: Gesucht sind praxistaugliche Lösungen zum realen Problem der Überwindung von (treppenartigen) Höhenunterschieden durch Rampenkonstruktionen. Die Modellierungsaufgabe wurde im Unterricht erprobt und kann ausgehend von den hier beschriebenen fachdidaktischen Ideen in Komplexität und Authentizität weiterentwickelt sowie an unterschiedliche Lernausgangslagen von Schüler/inne/n angepasst werden.
