Concept Cartoons zur UV-Strahlung

Abstract

Concept Cartoons stellen naturwissenschaftliche Phänomene mit Alltagsbezug graphisch dar und bieten vielfältige didaktische Einsatzmöglichkeiten. Das Herzstück dieser Arbeit bilden Concept Cartoons auf Basis relevanter fachdidaktischer Theorien. Sie werden zu zwei Sonderformen weiterentwickelt: Concept Cartoons mit gestuften Hilfen und gestufte Concept Cartoons. Erstere bieten den Lernenden Problemlösestrategien bei der Bearbeitung der Aufgabe an. Bei zweiteren werden zusätzliche Gegenargumente eingesetzt. Beide Formen der Concept Cartoons sollen sich positiv auf den Diskussionsprozess in der Gruppe auswirken. Die vorliegende Arbeit untersucht, inwiefern die beiden Formen der Concept Cartoons Diskussionen anregen und ihre inhaltliche Qualität beeinflussen. Dazu werden die Concept Cartoons in eine schülerzentrierte Unterrichtseinheit zur UV-Strahlung eingebettet, bei der die Lernenden sowohl fachliche als auch überfachliche Kompetenzen erwerben. Im Rahmen einer Vergleichsstudie wird untersucht, ob und wie sich die beiden Formate der Concept Cartoons auf den Diskussionsprozess auswirken und ob eine der beiden Versionen im Unterricht zu favorisieren ist. wird ein Feedbackbogen eingesetzt, um eine Selbsteinschätzung der Lernenden zu erhalten. Bei der Analyse der Ergebnisse zeigen die beiden Concept Cartoon Formate in ihrem Einfluss auf den Diskussionsprozess keine klaren Unterschiede, da der Einsatz von Concept Cartoons von diversen Faktoren abhängt.

Concept Cartoons illustrate phenomena from natural sciences in everyday life contexts and offer a variety of possible didactical applications. This thesis focuses on two Concept Cartoons based on solid theoretical fundaments of educational research. We specifically investigate two different types of Concept Cartoons: Concept Cartoons with stepped supporting tools and stepped Concept Cartoons. The latter includes counter arguments in addition to the baseline Concept Cartoon, while the first offers problem-solving strategies. Thus, both types of Concept Cartoons should affect discussion processes positively. This thesis examines the effects of these two types of Concept Cartoons on the discussion process and on the quality of the discussion. For this reason, we embed the Concept Cartoons into a student-centered teaching module on UV-radiation. With this module, students might acquire technical knowledge as well as interdisciplinary competences. Afterwards we analyze the findings from this implementation quantitatively and qualitatively. Moreover, we also capture students’ opinions via self-assessment feedback forms. The results show that there is no mayor difference between the two types of Concept Cartoons and their influence on the discussion process, as their use depends on a variety of factors.
