Raphael Wess – författare

This open access book presents a structural model and an associated test instrument designed to provide a detailed analysis of professional competences for teaching mathematical modelling. The conceptualisation is based on the COACTIV model, which describes aspects, areas and facets of professional competences of teachers. The manual provides an overview of the essential teaching skills in application-related contexts and offers the tools needed to capture these aspects. It discusses the objectives and application areas of the instrument, as well as the development of the test. In addition, it describes the implementation and evaluates the quality and results of the structural equation analysis of the model.Teaching mathematical modelling is a cognitively challenging activity for (prospective) teachers. Thus, teacher education requires a detailed analysis of professional competence for teaching mathematical modelling. Measuring this competence requires theoretical models thataccurately describe requirements placed upon teachers, as well as appropriate evaluation tools that adequately capture skills and abilities in this field. This book presents an instrument that measures the professional competences in a sample of 349 prospective teachers.

Raphael Wess stellt eine Interventionsstudie zur Entwicklung modellierungsspezifischer professioneller Kompetenz in zwölf mathematikdidaktischen Lehr-Lern-Labor-Seminaren vor. In seiner Studie vergleicht er die Kompetenzentwicklungen Studierender, die Modellierungsaufgaben für den Einsatz mit Schülerinnen und Schülern eigenständig erstellen, und Studierender, die in einem vergleichbaren Lehr-Lern-Labor die Modellierungsaufgaben nicht selbst konzipieren. Mithilfe der Item-Response-Theorie weist er nach, dass sich sowohl die Aufgaben- als auch die Diagnosekompetenz zum Lehren mathematischen Modellierens als eindimensionale Leistungsdisposition erfassen lässt. Es wird deutlich, dass die Konzeption von Modellierungsaufgaben und ihr Einsatz in der Praxis zu einer differenten Kompetenzentwicklung beider Gruppen führen. Ferner lassen sich unterschiedliche, die Kompetenzentwicklung beeinflussende Faktoren, wie etwa das Vorwissen oder Überzeugungen zum mathematischen Modellieren, identifizieren.
