Learning with Interactive Knowledge Representations

Computers are promising tools for providing educational experiences that meet individual learning needs. However, delivering this promise in practice is challenging, particularly when automated feedback is essential and the learning extends beyond using traditional methods such as writing and solving mathematics problems. We hypothesize that interactive knowledge representations can be deployed to address this challenge. Knowledge representations differ markedly from concept maps. Where the latter uses nodes (concepts) and arcs (links between concepts), a knowledge representation is based on an ontology that facilitates automated reasoning. By adjusting this reasoning towards interacting with learners for the benefit of learning, a new class of educational instruments emerges. In this contribution, we present three projects that use an interactive knowledge representation as their foundation. DynaLearn supports learners in acquiring system thinking skills. Minds-On helps learners to deepen their understanding of phenomena while performing experiments. Interactive Concept Cartoons engage learners in a science-based discussion about controversial topics. Each of these approaches has been developed iteratively in collaboration with teachers and tested in real classrooms, resulting in a suite of lessons available online. Evaluation studies involving pre-/post-tests and action-log data show that learners are easily capable of working with these educational instruments and that the instruments thus enable a semi-automated approach to constructive learning.

Researching the Mechanisms of Gossip in Organizations: From Fly on the Wall to Fly in the Soup

In this paper, I explored how to research a sensitive topic such as gossip in organizations and used a narrative approach to illustrate the methodological and ethical issues that come up when considering a variety of research methods. I first attempted to conduct an ethnographic research on a project group from a Dutch university undergoing a major change. At the very beginning of the project, as a participant observer, I struggled to remain an outsider, or a “fly on the wall.” But as issues of power came into play and access became increasingly problematic, I moved towards the role of an “observing participant.” Therefore, in order to research gossip and some of the hidden dimensions of organizational life, I turned to auto- and self-ethnography as a way to regain access and greater authenticity. While following this route presented its share of ethical and methodological issues, it also provided valuable insights that could be of value to researchers attempting to study sensitive topics such as gossip in organizations. https://nsuworks.nova.edu/tqr/vol23/iss7/18 LinkedIn: https://www.linkedin.com/in/dominiquedarmon/

How nursing home residents respond to the interactive art installation ‘Morgendauw’

This paper reports the responses of nursing home residents who live in a psychogeriatric ward to the abstract interactive art installation ‘Morgendauw’, which was specifically designed for this study. All stakeholders were involved in designing and implementing Morgendauw. The artwork seems able to evoke responses in both the residents and their caregivers, but the amount and duration of the responses observed during the study were limited. 15 interactions over the course of 14 h were noted and almost all of them were initiated by the nursing home staff, physiotherapy students or visitors (n = 12). Interactions lasted for about 3 min on average. Although the nursing home residents initially did not seem to notice the artwork, the threshold of acknowledging and approaching the artwork was quickly overcome when staff nudged or directed the residents’ attention towards the artwork. Beyond this point, nursing home residents generally needed little explanation of the interface to interact with the artwork. The location in which Morgendauw was placed during the study or the characteristics of the installation seemed to create a threshold. Further research should focus on the importance and the effects of context when designing and implementing an interactive art installation in a nursing home environment.

How nursing home residents with dementia respond to the interactive art installation ‘VENSTER'

The goal of this study was (1) to determine whether and how nursing home residents with dementia respond to the interactive art installation in general and (2) to identify whether responses change when the content type and, therefore, the nature of the interaction with the artwork changes. The interactive art installation ‘VENSTER’ evokes responses in nursing home residents with dementia, illustrating the potential of interactive artworks in the nursing home environment. Frequently observed responses were naming, recognizing or asking questions about depicted content and how the installation worked, physically gesturing towards or tapping on the screen and tapping or singing along to the music. It seemed content matters a lot. When VENSTER is to be used in routine care, the choice of a type of content is critical to the intended experience/usage in practice. In this study, recognition seemed to trigger memory and (in most cases) a verbal reaction, while indistinctness led to asking for more information. When (initially) coached by a care provider, residents actively engaged physically with the screen. Responses differed between content types, which makes it important to further explore different types of content and content as an interface to provide meaningful experiences for nursing home residents. •Implications for rehabilitation •VENSTER can facilitate different types of responses ranging from verbal reactions to active physical engagement. The choice of a type of content is critical to the intended experience/usage in practice. •Activating content seems suitable for use as a meaningful experience during the spare time in between existing activities or therapy. •Sessions with interactive content are short (avg. 30 mins) and intense and can therefore potentially be used as an activating therapy, activity or exercise. •In order to actively engage residents with dementia, the role of the care provider seems very important.

Reducing dementia related wandering behaviour with an interactive wall

People suffering from dementia often have problems with way finding and feel restless. In this paper we present an interactive wall developed for decreasing the amount of wandering behaviour of people suffering from dementia. The installation aims at making these people feel more at home in the nursing homes by guiding them with a motion triggered audio path. This leads them to a wall with large windows displaying images and short movie tracks from their hometown. The results of an observation study show that the interactive wall succeeds in attracting people and thus reducing the wandering behaviour. Remarks of the elderly as well as their family and caretakers support this conclusion.
