The number line<\/strong> (formerly AR number line<\/em>The app has been fundamentally expanded: It has evolved from a simple augmented reality app into a comprehensive learning tool for the number line \u2013 featuring an AI tutor, an adaptive learning system, and nine different exercise types and experimental environments with and without AR. The app is based on scientific findings from trials and is the subject of ongoing research.<\/p>\n\n\n\n

Three experimental environments<\/strong> \u2013 Neben dem Augmented-Reality-Modus gibt es einen mit Touch-Bedienung und Zeichenwerkzeugen sowie einen kombinierten Modus, der AR- und 2D-Ansicht synchron nebeneinander zeigt. In den Experimentierumgebungen kann mit den unterschiedlichen Zahlenstrahldarstellungen frei gearbeitet werden \u2013 hier sind keine Aufgabenstellungen enthalten.<\/p>\n\n\n\n
