While user‐centred design and user experience are given much attention in the e‐learning design field, no research has been found on how users are actually represented in the discussions during the design of online courses. In this paper we identify how and when end‐users' experience—be they students or tutors—emerges in designers' discussions during their meetings in well‐established open universities. More precisely, we observed 15 design meetings of two design teams during the development of specific online courses. Designers' discourse was analysed on the basis of six dimensions regarding relevant actors, contents and strategies (purposes) of user experience anticipation. Results show the emergence of a solution‐oriented anticipatory discourse in form of scenarios regarding how learners and tutors will react to the course and the proposed activities. Moreover, this discourse is related to an emergent type of users‐based expertise, translated as the capacity of some designers to empathise with the end‐users more than other designers do. The participation of designers with this type of expertise in e‐learning design teams emerges as relevant for the decisions related to the course activities, interface or overall experience. Further research is invited towards this direction. Further discussion on this article can be found in “Being in the users' shoes: Is there maybe another way?” (DOI: 10.1111/bjet.12104 ). 相似文献

In the current study, we have developed and fabricated a novel lab-on-a-chip device for the investigation of biofilm responses, such as attachment kinetics and initial biofilm formation, to different hydrodynamic conditions. The microfluidic flow channels are designed using computational fluid dynamic simulations so as to have a pre-defined, homogeneous wall shear stress in the channels, ranging from 0.03 to 4.30 Pa, which are relevant to in-service conditions on a ship hull, as well as other man-made marine platforms. Temporal variations of biofilm formation in the microfluidic device were assessed using time-lapse microscopy, nucleic acid staining, and confocal laser scanning microscopy (CLSM). Differences in attachment kinetics were observed with increasing shear stress, i.e., with increasing shear stress there appeared to be a delay in bacterial attachment, i.e., at 55, 120, 150, and 155 min for 0.03, 0.60, 2.15, and 4.30 Pa, respectively. CLSM confirmed marked variations in colony architecture, i.e.,: (i) lower shear stresses resulted in biofilms with distinctive morphologies mainly characterised by mushroom-like structures, interstitial channels, and internal voids, and (ii) for the higher shear stresses compact clusters with large interspaces between them were formed. The key advantage of the developed microfluidic device is the combination of three architectural features in one device, i.e., an open-system design, channel replication, and multiple fully developed shear stresses. 相似文献
