e-Learning research: emerging issues?
e-Learning research is an expanding and diversifying field of study. Specialist research units and departments proliferate. Postgraduate courses recruit well in the UK and overseas, with an increasing focus on critical and research-based aspects of the field, as well as the more obvious professional development requirements. Following this years launch of a National e-Learning Research Centre, it is timely to debate what the field of study should be prioritising for the future. This discussion piece suggests that the focus should fall on questions that are both clear and tractable for researchers, and likely to have a real impact on learners and practitioners. Suggested questions are based on early findings from a series of JISC-funded projects on e-learning and pedagogy
Trail records and navigational learning
An emerging wave of 'ambient' technologies has the potential to support learning in new and particular ways. In this paper we propose a 'trail model' of 'navigational learning' which links some particular learning needs to the potentialities of these technologies. In this context, we outline the design and use of an 'experience recorder', a technology to support learning in museums. In terms of policy for the e-society, these proposals are relevant to the need for personalised and individualised learning support
Cognitive trait model for persistent and fine-tuned student modelling in adaptive virtual learning environments : a thesis presented in partial fulfilment of the requirements for the degree of Master of Information Science in Information Systems at Massey University
The increasing need for individualised instructional in both academic and corporate training environment encourages the emergence and popularity of adaptivity in virtual learning environments (VLEs). Adaptivity can be applied in VLEs as adaptivity content presentation, which generates the learning content adaptively to suit the particular learner's aptitude, and as adaptive navigational control, which dynamically modifies the structure of the virtual learning environment presented to the learner in order to prevent overloading the learner's cognitive load. Techniques for both adaptive content presentation and adaptive navigational control need to be integrated in a conceptual framework so their benefits can be synthesised to obtain a synergic result. Exploration space control (ESC) theory attempts to adjust the learning space, called exploration space, to allow the learners to reach an adequate amount of information that their cognitive load is not overloaded. Multiple presentation (MR) approach provides guidelines for the selection of multimedia objects for both the learning content presentation and as navigational links. ESC is further formalised by including the consideration of individual learner's cognitive traits, which are the cognitive characteristics and abilities the learner relevant in the process of learning. Cognitive traits selected in the formalisation include working memory capacity, inductive reasoning skill, associative learning skill, and information processing speed. The formalisation attempts to formulate a guideline on how the learning content and navigational space should be adjusted in order to support a learner with a particular set of cognitive traits. However, in order to support the provision of adaptivity, the learners and their activities in the VLEs need to be profiled; the profiling process is called student modelling. Student models nowadays can be categorised into state models, and process models. State models record learners' progress as states (e.g. learned, not learned), whereas a process model represents the learners in term of both the knowledge they learned in the domain, and the inference procedures they used for completing a process (task). State models and process models are both competence-based, and they do not provide the information of an individual's cognitive abilities required by the formalisation of exploration space control. A new approach of student modelling is required, and this approach is called cognitive trait model (CTM). The basis of CTM lies in the field of cognitive science. The process for the creation of CTM includes the following subtasks. The cognitive trait under inquiry is studied in order to find its indicative signs (e.g. sign A indicates high working memory capacity). The signs are called the manifests of the cognitive trait. Manifests are always in pairs, i.e. if manifest A indicates high working memory capacity, A's inverse, B, would indicates low working memory capacity. The manifests are then translated into implementation patterns which are observable patterns in the records of learner-system interaction. Implementation patterns are regarded as machine-recognisable manifests. The manifests are used to create nodes in a neural network like structure called individualised temperament network (ITN). Every node in the ITN has its weight that conditions and is conditioned by the overall result of the execution of ITN. The output of the ITN's execution is used to update the CTM. A formative evaluation was carried out for a prototype created in this work. The positive results of the evaluation show the educational potential of the CTM approach. The current CTM only cater for the working memory capacity, in the future research more cognitive traits will be studied and included into the CTM
Integrating DGSs and GATPs in an Adaptative and Collaborative Blended-Learning Web-Environment
The area of geometry with its very strong and appealing visual contents and
its also strong and appealing connection between the visual content and its
formal specification, is an area where computational tools can enhance, in a
significant way, the learning environments.
The dynamic geometry software systems (DGSs) can be used to explore the
visual contents of geometry. This already mature tools allows an easy
construction of geometric figures build from free objects and elementary
constructions. The geometric automated theorem provers (GATPs) allows formal
deductive reasoning about geometric constructions, extending the reasoning via
concrete instances in a given model to formal deductive reasoning in a
geometric theory.
An adaptative and collaborative blended-learning environment where the DGS
and GATP features could be fully explored would be, in our opinion a very rich
and challenging learning environment for teachers and students.
In this text we will describe the Web Geometry Laboratory a Web environment
incorporating a DGS and a repository of geometric problems, that can be used in
a synchronous and asynchronous fashion and with some adaptative and
collaborative features.
As future work we want to enhance the adaptative and collaborative aspects of
the environment and also to incorporate a GATP, constructing a dynamic and
individualised learning environment for geometry.Comment: In Proceedings THedu'11, arXiv:1202.453
Issues in designing learning by teaching systems
Abstract: Learning by teaching systems are a relatively recent approach to designing Intelligent Learning Environments that place learners in the role of tutors. These systems are based on the practice of peer tutoring where students take on defined roles of tutor and tutee. An architecture for learning by teaching systems is described that does not require the domain model of an Intelligent Tutoring System. However a mutual communication language is needed and is defined by a conceptual syntax that delimits the domain content of the dialogue. An example learning by teaching system is described for the domain of qualitative economics. The construction and testing of this system inform a discussion of the major design issues involved: the nature of the learnt model, the form of the conceptual syntax, the control of the interaction and the possible introduction of domain knowledge. 1

Towards humanising creativity?
Within the context of developing creativity discourse and policy, this paper begins by exploring a number of the tensions that emerged from research using an interdisciplinary framework to investigate creativity with English expert specialist dance teachers. The paper then interrogates and articulates the productive dynamics of one of these tensions that occur between individual, collaborative and communal creativity. This tension is discussed within the wider debate of individualised versus collaborative/communal creativity and the encouragement of the former by individualised, marketised creativity policies. It is argued that one constructive product of articulating how dance professionals negotiate this tension within education is a pertinent and helpful example of a more humane framework for creativity than that espoused by the individualised marketisation agenda. In turn the paper draws out the idea of humanising creativity as a productive process that has the potential to challenge aspects of the dominant policy discourse in an emergent way
Ants don't have friends: thoughts on socially intelligent agents
The question what is an agent? has been under dis cussion for many years. However, a consensus exists that the term 'agent' only makes sense in a multi-agent context - namely if there are at least two agents and assuming interaction and or communication between the agents. Agent research is generally done fairly independently in dfferent research areas, separated by the nature of the agents - natural or articial. This paper presents some thoughts on agency and sociality. Social intelligence is studied in the context of human style forms of social behaviour. Issues like embodiment, believability, rationality, social understanding,and different levels of social organisation and control are discussed
Disability and special education needs : some perennial European concerns
In this brief paper I propose to first, offer some opening remarks including my reasons for personal involvement in this particular field of study. Secondly, I will identify some key issues relating to disability which European societies are struggling with. Finally, I will make some concluding remarks. In this paper I have been very selective over the issues I will attempt to briefly examine. Please do not see this as implying that I do not feel equally passionate about other issues such as parental participation. I do not want to give the impression that European societies have effectively engaged with these issues and all that is necessary is to emulate them. Nothing could be further from the truth. These are some key concerns that are being struggled over. Thus all European societies are open to criticism on each of these issues. Finally, educational issues, and disability is no exception, are complex, contradictory and contentious. This topic, therefore, raises the most fundamental questions and values. The process of engagement is thus both exciting and disturbing.peer-reviewe
Voltage uprating of existing 275kV overhead transmission line tower for increasing the power transfer capability
This project presents a methodological approach, suggestions and information
in uprating the existing 275kV transmission overhead line. The work also calculate
and analyses the effect of conductor swing angle on L3 tower top geometrics and keep
the probability of flashover at low state. In this project, the insulator length and
clearances of swing conductor to tower body, top cross-arm, bottom cross-arm and
conductor to conductor are considered. The purpose of this work is to determine the
clearances necessary to insulator withstand for 400kV line. In addition, it is also
important to make sure that conductors have to maintain the clearances under TOV
(temporary over-voltage), switching and lightning overvoltages. The work in this
project have used Excel and Smart Draw to analyze the results and plot the clearance
distances of swing conductor, also the phase to phase rms voltage and redrawing the
existing overhead tower. Therefore, voltages rating for the L3 tower can be
determined through the available clearances. Firstly, the voltage rating is determined
with standard 400kV specification of insulator length. Then, the insulator is being
shorted to do the analysis to the voltage rating and lastly, the overall cross-arm is
changed to fully insulate such as composite cross-arm. As the result, by using standard
insulator length, the tower only carried 351kV rather than composite cross-arm that
carry 450kV. The standard L3 tower will be increase the power transfer capacity to
400kV in term of voltage by changing the steel cross-arm to composite cross-arm

Artificial Intelligence And Big Data Technologies To Close The Achievement Gap.
We observe achievement gaps even in rich western countries, such as the UK, which in principle have the resources as well as the social and technical infrastructure to provide a better deal for all learners. The reasons for such gaps are complex and include the social and material poverty of some learners with their resulting other deficits, as well as failure by government to allocate sufficient resources to remedy the situation. On the supply side of the equation, a single teacher or university lecturer, even helped by a classroom assistant or tutorial assistant, cannot give each learner the kind of one-to-one attention that would really help to boost both their motivation and their attainment in ways that might mitigate the achievement gap.
In this chapter Benedict du Boulay, Alexandra Poulovassilis, Wayne Holmes, and Manolis Mavrikis argue that we now have the technologies to assist both educators and learners, most commonly in science, technology, engineering and mathematics subjects (STEM), at least some of the time. We present case studies from the fields of Artificial Intelligence in Education (AIED) and Big Data. We look at how they can be used to provide personalised support for students and demonstrate that they are not designed to replace the teacher. In addition, we also describe tools for teachers to increase their awareness and, ultimately, free up time for them to provide nuanced, individualised support even in large cohorts
