Lecture, narrated slides, or first person view? Impact of presentation on learning outcomes

We are experimentally conducting a fine-grain comparative analysis of two different methods of producing pre-recorded lectures versus a traditional live lecture. The two different pre-recorded lecture production methods do not require assistance from university staff members and therefore represent a low-cost approach. The first method is generating narrated slides using PowerPoint during a live lecture and the second method is the recording of a live lecture from the instructor´s point of view using a head mounted camera such as Google´s Glass. We present some of our preliminary results of this comparative analysis, which indicate that little interactions exist overall between the implemented modus of presenting instructional materials and the observed student learning gains within the study configuration. Thus, as a preliminary indicator within our study confines, instructors are enabled to select the most convenient fashion of lecture presentation. We are presently expanding our set of experiments (different cohorts, different specific subject matter, etc.) to obtain broader conclusions.
