The role of learning goals in the design of ILEs: some issues to consider

Part of the motivation behind the evolution of learning environments is the idea of providing students with individualized instructional strategies that allow them to learn as much as possible. It has been suggested that the goals an individual holds create a framework or orientation from which they react and respond to events. There is a large evidence-based literature which supports the notion of mastery and performance approaches to learning and which identifies distinct behavioural patterns associated with each. However, it remains unclear how these orientations manifest themselves within the individual: an important question to address when applying goal theory to the development of a goal-sensitive learner model. This paper exposes some of these issues by describing two empirical studies. They approach the subject from different perspectives, one from the implementation of an affective computing system and the other a classroom-based study, have both encountered the same empirical and theoretical problems: the dispositional/situational aspect and the dimensionality of goal orientation

An examination of factors impacting the Implementation of Information Technology Shared Services (ITSS) in UK local government bodies

The Conservative and Liberal Democrats coalition government was formed in the year 2010 and embarked on austerity measures aimed at reducing the UK’s budget deficit. Among the measures that were proposed was the need for local governments to find ways of reducing their cost of operations. One way of reducing costs was through sharing resources. This measure was proposed in the Gershon report, commissioned by the central government. Information technology is a vital resource for running the operations of local governments. Sharing of information technology became crucial in facilitating sharing of other resources by Local Government bodies. There is, however, the need to take into consideration a number of factors in order to ensure that sharing of Information technology (Information Technology Shared Services – ITSS) resources is successful. Factor consideration involves implementation processes that take into account the constraints or facilitators that can be categorised into Technological, Organisational and Environmental categories. Through the review of academic literature, government records, news articles and from the interviews that were held with respondents from Local Government bodies, using advanced qualitative research method and Nvivo as an analytical tool, it was found that beside the reduction of costs and efficiency motives, sharing of Information Technology also impacted work culture and changes to internal processes. The main contribution of this thesis is that Information Technology Shared Services led to long term (or permanence of) association among Local Councils. This degree of permanence of association is beneficial for meeting the main objectives of each council, but also has the potential to lead to loss of autonomy by individual local authorities. Local government managers (management bodies) had to consider the ‘How? When? What?’ questions in order to implement the sharing of information technology resources. This research proposes further examination of the Technological, Organisational and Environmental (TOE) framework through the prism of a Technology Sharing Implementation Framework (TSIF). The proposed framework examines the impacts of TOE factors on implementing sharing of information technology processes / resources and why these factors have to be examined jointly, not disparately, when seeking to implement information technology resources. Mention has been made about examining these factors by assigning weights on them and using quantitative measures to show the importance of the factors. Implementation process of ITSS has been proposed for local government managers

Adaptive intelligent tutoring for teaching modern standard Arabic

A thesis submitted to the University of Bedfordshire, in partial fulfilment of the requirements for the degree of Doctor of PhilosophyThe aim of this PhD thesis is to develop a framework for adaptive intelligent tutoring systems (ITS) in the domain of Modern Standard Arabic language. This framework will comprise of a new approach to using a fuzzy inference mechanism and generic rules in guiding the learning process. In addition, the framework will demonstrate another contribution in which the system can be adapted to be used in the teaching of different languages. A prototype system will be developed to demonstrate these features. This system is targeted at adult English-speaking casual learners with no pre-knowledge of the Arabic language. It will consist of two parts: an ITS for learners to use and a teachers‘ tool for configuring and customising the teaching rules and artificial intelligence components among other configuration operations. The system also provides a diverse teaching-strategies‘ environment based on multiple instructional strategies. This approach is based on general rules that provide means to a reconfigurable prediction. The ITS determines the learner‘s learning characteristics using multiple fuzzy inferences. It has a reconfigurable design that can be altered by the teacher at runtime via a teacher-interface. A framework for an independent domain (i.e. pluggable-domain) for foreign language tutoring systems is introduced in this research. This approach allows the system to adapt to the teaching of a different language with little changes required. Such a feature has the advantages of reducing the time and cost required for building intelligent language tutoring systems. To evaluate the proposed system, two experiments are conducted with two versions of the software: the ITS and a cut down version with no artificial intelligence components. The learners used the ITS had shown an increase in scores between the post-test and the pre-test with learning gain of 35% compared to 25% of the learners from the cut down version

Supporting learning in intelligent tutoring systems with motivational strategies.

Motivation and affect detection are prominent yet challenging areas of research in the field of Intelligent Tutoring Systems (ITSs). Devising strategies to engage learners and motivate them to practice regularly are of great interest to researchers. In the learning and education domain, where students use ITSs regularly, motivating them to engage with the system effectively may lead to higher learning outcomes. Therefore, developing an ITS which provides a complete learning experience to students by catering to their cognitive, affective, metacognitive, and motivational needs is an ambitious yet promising area of research. This dissertation is the first step towards this goal in the context of SQL-Tutor, a mature ITS for tutoring SQL. In this research project, I have conducted a series of studies to detect and evaluate learners' affective states and employed various strategies for increasing motivation and engagement to improve learning from SQL-Tutor. Firstly, I established the reliability of iMotions to correctly identify learners' emotions and found that worked examples alleviated learners' frustration while solving problems with SQL-Tutor. Gamification is introduced as a motivational strategy to persuade learners to practice with the system. Gamification has emerged as a strong engagement and motivation strategy in learning environments for young learners. I evaluated the effects of gamified SQL-Tutor on undergraduate students and found that gamification indirectly improved learning by influencing learners’ time on task. It helped students by increasing their motivation which produce similar effects as intrinsically motivated students. Additionally, prior knowledge, gamification experience, and interest in the topic moderated the effects of gamification. Lastly, self-regulated learning support is presented as another strategy to affect learners’ internal motivation and skills. The support provided in the form of interventions improved students’ learning outcomes. Additionally, the learners' challenge-accepting behaviour, problem selection, goal setting, and self-reflection have improved with support without experiencing any negative emotions. This research project contributes to the latest trends of motivation and learning research in ITS

Rubric-based Learner Modelling via Noisy Gates Bayesian Networks for Computational Thinking Skills Assessment

In modern and personalised education, there is a growing interest in developing learners’ competencies and accurately assessing them. In a previous work, we proposed a procedure for deriving a learner model for automatic skill assessment from a task-specific competence rubric, thus simplifying the implementation of automated assessment tools. The previous approach, however, suffered two main limitations: (i) the ordering between competencies defined by the assessment rubric was only indirectly modelled; (ii) supplementary skills, not under assessment but necessary for accomplishing the task, were not included in the model. In this work, we address issue (i) by introducing dummy observed nodes, strictly enforcing the skills ordering without changing the network’s structure. In contrast, for point (ii), we design a network with two layers of gates, one performing disjunctive operations by noisy-OR gates and the other conjunctive operations through logical ANDs. Such changes improve the model outcomes’ coherence and the modelling tool’s flexibility without compromising the model’s compact parametrisation, interpretability and simple experts’ elicitation. We used this approach to develop a learner model for Computational Thinking (CT) skills assessment. The CT-cube skills assessment framework and the Cross Array Task (CAT) are used to exemplify it and demonstrate its feasibility

Empowering educators to be AI-ready

In this paper, we present the concept of AI Readiness, along with a framework for developing AI Readiness training. ‘AI Readiness’ can be framed as a contextualised way of helping people to understand AI, in particular, data-driven AI. The nature of AI Readiness training is not the same as merely learning about AI. Rather, AI Readiness recognises the diversity of the professions, workplaces and sectors for whom AI has a potential impact. For example, AI Readiness for lawyers may be based on the same principles as AI Readiness for Educators. However, the details will be contextualised differently. AI Readiness recognises that such contextualisation is not an option: it is essential due to the multiple intricacies, sensitivities and variations between different sectors and their settings, which all impact the application of AI. To embrace such contextualisation, AI Readiness needs to be an active, participatory training process and aims to empower people to be more able to leverage AI to meet their needs. The text that follows focuses on AI Readiness within the Education and Training sector and starts with a discussion of the current state of AI within education and training, and the need for AI Readiness. We then problematize the concept of AI Readiness, why AI Readiness is needed, and what it means. We expand upon the nature of AI Readiness through a discussion of the difference between human and Artificial Intelligence, before presenting a 7-step framework for helping people to become AI Ready. Finally, we use an example of AI Readiness in action within Higher Education to exemplify AI Readiness

Supporting students’ confidence judgement through visualising alignment in open learner models

Supporting students’ knowledge monitoring skills, a component of metacognition, can help students regulate their own learning. This thesis investigates the alignment of learners’ confidence in their knowledge with a computer’s assessment of their knowledge, visualised using an Open Learner Model (OLM). The research explored students’ preferred method for visualising inconsistent data (e.g. misalignment) in an OLM, and the ways in which visualising alignment can influence student interaction with the computer. The thesis demonstrates that visualising alignment in Open Learner Models signifi-cantly increases students’ confidence compared to a control condition. In particular, visualising alignment benefited low-achieving students, in terms of knowledge monitoring and this was associated with improvements in their performance. Students showed a preference towards the visualisations that provides an overview of the in-formation (i.e. opacity) rather than ones, which provide detailed information. Graph-ical representation is shown to be more beneficial in motivating students to interact with the system than text-based representation of the same information in the con-text of representing the alignment within OLMs
