The disfluency effect postulates that intentionally inserted desirable difficulties can have a beneficial effect on learning. Nevertheless, there is an ongoing discussion about the emergence of this effect since studies could not replicate this effect or even found opposite effects. To clarify boundary effects of the disfluency effect and to investigate potential social effects of disfluency operationalized through handwritten material, three studies (N 1 = 97; N 2 = 102; N 3 = 103) were carried out. In all three experiments, instructional texts were manipulated in terms of disfluency (computerized font vs. handwritten font). Learning outcomes and cognitive load were measured in all experiments. Furthermore, metacognitive variables (Experiment 2 and 3) and social presence (Experiment 3) were measured. Results were ambiguous, indicating that element interactivity (complexity or connectedness of information within the learning material) of the learning material is a boundary condition that determines the effects of disfluency. When element interactivity is low, disfluency had a positive effect on learning outcomes and germane processes. When element interactivity increases, disfluency had negative impacts on learning efficiency (Experiment 2 and 3) and extraneous load (Experiment 3). In contrast to common explanations of the disfluency effect, a disfluent font had no metacognitive benefits. Social processes did not influence learning with disfluent material as well.
360° videos raised the attention of educators, as they can mediate complex environments in educational settings. However, learning irrelevant cognitive strains might be imposed because it is necessary to navigate through spherical material. These downsides could be compensated by using signalling techniques. In a two (macro‐level vs. no signalling) × two (micro‐level vs. no signalling) factorial between‐subjects design plus control group, 203 students watched a video about visual and behavioural characteristics of animals. Learning outcomes, cognitive load, disorientation, and presence were investigated. Results revealed that macro‐level signalling enhanced learning outcomes. Descriptively, the control group outperformed all experimental groups except the condition with macro‐level signalling regarding retention performance. According to an exploratory path model, extraneous load moderated the effects of signalling on learning outcomes. Results are discussed considering cognitive load and spatial presence induced by using 360° videos as learning material.
