One of the key interests for learning analytics is how it can be used to improve retention. This paper focuses on work conducted at the Open University (OU) into predicting students who are at risk of failing their module. The Open University is one of the worlds largest distance learning institutions. Since tutors do not interact face to face with(More)
The media curation craze has spawned a multitude of new sites that help users to collect and share web content. Some market themselves as spaces to explore a common interest through different types of related media. Others are promoted as a means for creating and sharing stories, or producing personalized newspapers. Still others target the education(More)
BACKGROUND Thymic carcinoma (TC) is a rare aggressive tumour. Median survival with current treatments is only 2 years. Sunitinib is a multi-targeted tyrosine kinase inhibitor that has shown benefit in various other cancers. METHODS Laboratory analyses of snap-frozen tumour tissues were performed to detect activation and genetic mutations of receptor(More)
Learning analytics (LA) as a field remains in its infancy. Many of the techniques now prominent from practitioners have been drawn from various fields, including HCI, statistics, computer science, and learning sciences. In order for LA to grow and advance as a discipline, two significant challenges must be met: 1) development of analytics methods and(More)
Museum narratives, like other forms of narrative, are developed from an underlying conceptualization of events that can be referred to as the story. Storyscope is a web-based environment for constructing and exploring museum narratives and their underlying concepts. Storyscope aligns with a formal model of story and narrative specialized for a museum(More)
This paper explores the potential of analytics for improving accessibility of e-learning and supporting disabled learners in their studies. A comparative analysis of completion rates of disabled and non-disabled students in a large five-year dataset is presented and a wide variation in comparative retention rates is characterized. Learning analytics enable(More)
This paper presents a model, called Scene-Driver, for the reuse of film and television material. We begin by exploring general issues surrounding the ways in which content can be sub-divided into meaningful units for re-use and how criteria might then be applied to the selection and ordering of these units. We also identify and discuss the different means(More)
In a curated exhibition of a museum or art gallery, a selection of heritage objects and associated information is presented to a visitor for the purpose of telling a story about them. The same underlying story can be presented in a number of different ways. This paper describes techniques for creating multiple alternative narrative structures from a single(More)
We report our case series involving the use of a MicroOptical™ (MicroOptical™ Corporation, Westwood, MA, USA) head mounted, computer display monitor during orthopaedic procedures such as open reduction and internal fracture fixations and spinal pedicle screw placement. Since the MicroOptical™ viewer does not fully obstruct the surgeon’s direct vision,(More)
Existing metadata schemes and content management systems used by museums focus on describing the heritage objects that the museum holds in its collection. These are used to manage and describe individual heritage objects according to properties such as artist, date and preservation requirements. Curatorial narratives, such as physical or online exhibitions(More)
