This paper describes the accretion representation for scrutable student modelling. Essentially, the representation maintains a times-tamped collection of the evidence about each component of the student model. This is interpreted by a resolver at the time that a teaching program needs to determine the value of parts of the model. The accretion representation treats external evidence as ground assumptions which are normally kept long term. By contrast, the student modelling system’s internal inferences are handled quite differently. This approach supports long-term modelling of the learner’s knowledge and other characteristics. It was used in large scale modelling and coaching experiments for knowledge of a text editor. An important concern for the representation is to support scrutability of the student model. This notion is explained in the paper and linked to the design of the accretion representation.

ABSTRACT Tabletops have the potential to provide new ways to support collaborative learning generally and, more specifically, to aid people in learning to collaborate more effectively. To achieve this potential, we need to gain understanding of how to design tabletop environments so that they capture relevant information about collaboration processes so that we can make it available in a form that is useful for learners, their teachers and facilitators. This paper draws upon research in computer supported collaborative learning to establish a set of principles for the design of a tabletop learning system. We then show how these have been used to design our Collaid (Collaborative Learning Aid) environment. Key features of this system are: capture of multi-modal data about collaboration in a tabletop activity using a microphone array and a depth sensor; integration of these data with other parts of the learning system; transforming the data into visualisations depicting the processes that occurred during the collaboration at the table; and sequence mining of the interaction logs. The main contributions of this paper are: our design guidelines to build the Collaid environment and the demonstration of its use in a collaborative concept mapping learning tool applying data mining and visualisations of collaboration.

The Active Model (AM) is a novel approach to supporting context-aware ubiquitous services. At its core are active models for peo- ple, sensors, devices and places. These make it possible to quickly build and augment flexible ubiquitous personalisation services. We use a pro- totype implementation of a music presentation system to illustrate the active, distributed models and associated resource discovery.

ABSTRACT Personal sensors track data about many aspects of our lives. This data can be used to form a long-term user model to help people self reflect on their long-term goals. Yet, there is a dearth of work on designing the infrastructure and associated interfaces so that people can control the data stored in their user models, enabling them to use and manipulate their own data as they wish. We have conducted a survey with over 100 participants to gain an understanding of people's attitudes towards controlling their data. This paper presents the design of the survey and reports on its results. We explored control issues in terms of three sensors for weight, activity and inactivity. Our results paint a nuanced picture of user preferences. We conclude with implications for designing long-term user modelling systems for user control of personal sensor data.

ABSTRACT We report our work towards building user models of learner's devel- opment based upon evidence of their interactions with an e -learning website composed of multimedia learning objects. Essentially, this involves three ele- ments: effective metadata for each learning object; analysis of each user's time spent with each learning object; reasoning about each individual's knowledge of the course that is based upon a collection of learning objects. In this chapter, we focus on the problem of creating the metadata in a manner that will support ef- fective user modelling. The chapter begins with a brief discussion of our overall architecture for building a user model and defining the metadata for multi-media learning objects. We then describe Metasaur, the interface used to create the metadata, and SIV, the visualisation interface to support users in scrutinising the reasoning about them. We also briefly describe the process used to construct an ontology automatically from an existing dictionary. Importantly, we describe an extension that enables a person to create new metadata terms and link these elegantly into the ontology. We report a qualitative study in the use of the Me- tasaur interface for its two roles, creation of metadata and scrutiny of the user modelling processes.

This paper explores two classes of emerging technology that offer the promise to provide radically improved ways to support lifelong learning. We particularly focus on the human computer interaction (HCI) challenges that must be addressed if that promise is to be realised. One technology is personalisation, based on a long term learner model which captures the learner’s knowledge, preferences and other attributes. We discuss the roles of an explicit learner model that is a first class software entity, with APIs for programmers as well as effective user interfaces that can give users control over their model and its use. We present the PLUS framework that provides the infrastructure for personalised learning, and how its Accretion-Resolution representation supports both flexible reasoning for personalisation by programs and provides the foundation for users to control the whole personalisation process. We link the PLUS framework to a second class of technology, the fast-changing and increasingly ubiquitous personal mobile devices and the emerging embedded surface computing devices, such as tabletop and shared wall displays. We show how we have tackled several of the HCI challenges that are key to both these technologies.
