| | All evaluations were performed by the research group Didactics and Evaluation in virtualized Learning (DEviL) which belongs to the department of education II at the University of Mannheim. DEviL is dedicated to attend, consult and evaluate multimedial teaching concepts.
Two experimental investigations of the new scenario were conducted. (in this semester, the third study is running). In a first trial in a computer science lecture (N=44), the quiz service was implemented for the use on mobile computers. The students participated either in an interactive or a conventional lecture session. The groups were compared regarding to acceptance and success in learning. With respect to acceptance, the interactive condition was evaluated significantly better than the conventional one. Concerning the learning outcome the results for the interactive scenario were superior when compared to the conventional setting.
In the second study (N = 99), a long-term integration of the quiz service was implemented as well as an experimental application of the call-in-service. Again, the lecture was part of a computer science course. Besides, the lecture was transmitted to the University of Freiburg as a tele-lecture, and the students at the remote location were likewise included into the investigation actively. Additionally to acceptance and knowledge acquisition, data concerning current motivation and attention were obtained continuously in all meetings. The highly positive acceptance values of the preliminary investigation were replicated. Besides, a significant higher and faster learning increase was observed in the interactive condition.
The results highlight the potential of the Interactive Lecture scenario for didactic and technical improvements in higher education. |  |  |
