Abstract
In einer empirischen Untersuchung wurde eine mittels Macromedia Director 6.0 entwickelte Lernsoftware zum Thema "Routineeingriffe in der Kinderchirurgie" evaluiert. Das multimediale Lernprogramm wurde an einer Stichprobe von 121 Medizinstudenten hinsichtlich gestalterischer Merkmale, motivationalen Effekten, Einstellungen und Maßen des Wissenserwerbes untersucht. Es wurden 121 Medizinstudenten randomisiert (medianes Alter 24; Spannweite: R=21-33) in 2 Gruppen aufgeteilt. Diese haben sich über 90 Minuten entweder mit dem Lernprogramm (CBT: n=71) oder in einem Seminar (Kurs: n=50) auf den Lernstoff vorbereitet. Eine Woche nach der Lernphase wurde mittels MC-Fragen ein Wissenstest durchgeführt. Nach einem zusätzlichen Bed-Side-Teaching für beide Gruppen wurden die Studenten durch den Dozenten geprüft. Hierbei wurde der klinische Umgang, der Problemzugang und die chirurgische Entscheidungsfindung evaluiert. Bezüglich des Wissenstestes zeigte sich zwischen beiden Gruppen ein statistisch signifikanter Unterschied zugunsten der CBT-Bedingung (P < 0.001) (CBT: Median=5; R=2.67 - 9.2 Punkte von 10 vs. Kurs: Median=3.16; R=1.0-7.0 Punkte). Beim Vergleich der beiden Gruppen hinsichtlich der evaluierten Faktoren wie klinischem Umgang, Angehen von Problemen und chirurgischer Entscheidungsfindung zeigte die CBT-Gruppe ein im Durchschnitt um 25% besseres Ergebnis gegenüber der Kontrollgruppe. Aufgrund der durchgeführten Untersuchung kann festgestellt werden, daß Lehr-Lernmodule in der Chirurgie zur signifikanten Steigerung der Vermittlung medizinischen Wissens und zur verbesserten Ausbildung des deduktiven Denkens führen.
