Abstract
Introduction: The aim of the study was to examine the effect of an elaborate feedback and an audience response system (ARS) on learning success. Methods: Students of the 1st clinical semester were randomly assigned to a study and a control group. The randomization was carried out considering the factors of age, gender and power spectrum during preliminary dental examination. Within 10 lectures 5 multiple-choice questions were asked about the learning objectives and answered by the students using an ARS. Only the study group received an immediate comprehensive feedback on the results. A final exam at the end was carried out in order to evaluate whether the elaborate feedback leads to a successful learning. Furthermore the effect of the ARS on the lecture atmosphere was investigated. Result: The results of the final exams showed no significant difference between the study and the control group regarding the learning success. Conclusion: Although no significant effect on learning success was found, the ARS creates a more interactive, positive learning environment.
