The empirical evidence concerning the question whether an instructor should be presented on online lecture slides is equivocal and two lines of theoretical reasoning exist. On the one hand, the instructor may distract from the content, thereby hampering learning; on the other hand, the instructor may function as a social cue that triggers a more…

Multitasking refers to the simultaneous execution of two or more tasks. Perceived multitasking superiority of the digital natives and gifted students in the popular education literature need to be investigated with robust studies. In this regard, the effect of different multitasking scenarios on multimedia learning was investigated with 93 gifted…

For learners, it can be difficult to imagine how to perform a complex skill based on textual information from solely a text-based analytic rubric. Rubrics lack (1) the contextual information needed to convey real-world attributes (2) the dynamic information (such as gesturing in the complex skill of presenting) (3) the procedural information…

Implementing online technologies alone cannot ensure learning. A verified approach is needed to optimize the pedagogical effect of online learning. Previous studies have suggested that the application of the modality principle in multimedia design improves the efficiency of learning by reducing cognitive load. Nevertheless, this design approach…

This study assessed the role different kinds of secondary tasks play for researching the modality effect of cognitive load theory. Ninety-six university students worked with a computer-based training program for approximately 13 min and had to fulfill an additional secondary task. In a 2 x 2 factorial design, modality of information presentation…

The purpose of this study was to examine the effects of diagrams and time-compressed instruction on learning and learners' perceptions of cognitive load. The following design factors, visuals (visuals and non-visuals) and time-compressed instruction (0%-normal paced, 25, and 50%) were presented to 216 university students to analyze learning in a…

Educational multi-user virtual environments (MUVEs) have been shown to be effective platforms for situated science inquiry curricula. While researchers find MUVEs to be supportive of collaborative scientific inquiry processes, the complex mix of multi-modal messages present in MUVEs can lead to cognitive overload, with learners unable to…
