@article{Schulz_2022, title={Wie und mit welchem Erfolg dividieren angehende Primarlehrpersonen natürliche Zahlen, gemischte Brüche und Dezimalzahlen? Eine fokussierte Analyse mathematischen Wissens von Studienanfängern mit Folgerungen für die Ausbildung}, url={https://attidida.supsi.ch/index.php/dida/article/view/41}, DOI={10.33683/dida.22.05.81}, abstractNote={<div class="container"> <div class="sixteen columns"> <div class="contact_form">&nbsp;</div> </div> </div> <div id="footer_bottom"> <div class="container"> <div class="eight columns">Das Dividieren mit mehrstelligen Zahlen sowie das Verständnis und Operieren mit rationalen Zahlen ist für Schüler:innen herausfordernd und stellt zudem wichtige Grundlagen für ein erfolgreiches Weiterlernen in der Domäne Mathematik dar. Um Schüler:innen angemessen zu fördern, müssen Lehrpersonen selbst in der Lage sein, die zu bearbeitenden Probleme auf flexible, verstehensbasierte und kreative Weise zu lösen. Daher fokussiert die hier vorgestellte Studie auf mathematisches Wissen angehender Primarschullehrpersonen zur Division mit natürlichen und rationalen Zahlen. Zunächst wurde theoretisch analysiert, worauf Schwierigkeiten im Verständnis und in der prozeduralen Geläufigkeit zur Division zurückzuführen sein können. Darauf aufbauend wurden entsprechende Testaufgaben entwickelt und in Erhebungen mit angehenden Primarschullehrpersonen im ersten und dritten Semester eingesetzt. Die Befunde verdeutlichen, dass bei einem nennenswerten Anteil der Studierenden zum Studienbeginn sowie im dritten Semester Lücken im Verständnis und in der prozeduralen Geläufigkeit zur Division mit natürlichen und rationalen Zahlen bestehen. Die Befunde werden hinsichtlich ihrer Konsequenzen für die Gestaltung der fachdidaktischen Ausbildung angehender Primarschullehrpersonen und vor dem Hintergrund begrenzt zur Verfügung stehender Ausbildungszeit interpretiert und diskutiert.</div> </div> </div> <div class="bsa_fixed-leaderboard"> <div id="bsa-zone_1615580517822-2_123456" data-google-query-id="CMn01PeutfsCFQPLUQodTgMGTw"> <div id="google_ads_iframe_/8691100/StripHTML_S2S_FixedFooter_ROS_Pos1_0__container__" style="border: 0pt none; margin: auto; text-align: center; width: 320px; height: 50px;"><iframe id="google_ads_iframe_/8691100/StripHTML_S2S_FixedFooter_ROS_Pos1_0" style="border: 0px none; vertical-align: bottom;" tabindex="0" title="3rd party ad content" role="region" src="https://70b462aa0005439c9c31d9114c1999f3.safeframe.googlesyndication.com/safeframe/1-0-40/html/container.html" name="1-0-40;19387;<!doctype html><html><head></head><body leftMargin=&quot;0&quot; topMargin=&quot;0&quot; marginwidth=&quot;0&quot; marginheight=&quot;0&quot;><script src=&quot;https://tpc.googlesyndication.com/safeframe/1-0-40/js/ext.js&quot;></script><script>window.dicnf = {};</script><script data-jc=&quot;41&quot; data-jc-version=&quot;r20221110&quot; data-jc-flags=&quot;[&amp;quot;x%278446&amp;#39;9efotm(&amp;amp;20067;&amp;gt;8&amp;amp;&amp;gt;`dopb/%&amp;lt;1732261!=|vqc)!7201061?&amp;#39;9efotmy&amp;quot;]&quot;>(function(){/* Copyright The Closure Library Authors.
