Technologically, the learning computer is distinguishable from either a LMS or a LCMS by its distributed<br />

functionality, asynchronous communications and integrated interface. But its most significant difference is that the<br />

distance students themselves, rather than the education providers, are the primary target users. An integrated, holistic<br />

approach is taken to e-learning in which the usability of the student’s overall computing environment is considered<br />

as important to successful learning outcomes as the learning content itself.<br />

The IMMEDIATE prototype is first and foremost a specialised learning environment in which network and<br />

education provider features are designed as support services rather than as authoring, teaching or course<br />

administration productivity tools. It demonstrates the potential for specialised computing environments to address<br />

usability concerns resulting from the increasing complexity of general purpose systems as they encompass more and<br />

more functions and features.<br />

IMMEDIATE models the forms in which learning will be delivered, while leaving most content to be authored<br />

separately or picked up from reusable learning repositories. The learning interface is assembled from reusable<br />

learning components, an extension of the drag and drop components of visual programming tools like Delphi or<br />

Visual Studio. Learning components differ from reusable software components (controls) in that they encapsulate a<br />

specific learning domain task rather than a more generally-applicable software feature. They differ from reusable<br />

learning objects in that they implement the form in which the content will be displayed rather than the content of a<br />

learning module. The learning components are the centrepiece of a modular construction which supports reuse on<br />

three levels – the student (multiple courses), the teacher (reusable learning materials), and the software engineer<br />

(reusable code).<br />

By combining an emphasis on interface design − especially user-centred adaptable and collaborative strategies −<br />

with an emphasis on e-learning as an extension of the human teacher and the university, the framework for an<br />

integrated, individualised, multi-dimensional, easy-to-use learning environment has been laid. This supports the<br />

findings of Murray et al. (2000) that “good interface design and passive but powerful user features can sometimes<br />

provide the benefits that are ascribed to more sophisticated or intelligent features” (para. 41).<br />

The learning computer concept is also distinct in that it draws upon the ubiquitous (embedded) computing approach<br />

to e-learning (Bork, 2001; Hoppe et al, 2000). The object is to so seamlessly embed the computer functionality into<br />

the learning domain – by taking into account the total context including hardware, software and human factors – that<br />

the computer will vanish for the learner. We are trying to enhance and extend the university learning environment<br />

rather than create an alternative virtual one.<br />

The Learning Shell uses specialised software to embed the computer in the learning environment in the form of a<br />

graphical user shell over the most widely-used family of operating systems, Microsoft Windows. In this way we<br />

implement a “what” interface centred upon the task in the user’s domain rather than a “how” interface focussed<br />

upon the computing mechanisms for achieving that task. This addresses a long-recognised challenge for simplifying<br />

and improving the usability of computer systems, as discussed in Gentner and Grudin (1990). The next challenge is<br />

to extend this approach to support special-purpose hardware, cross-platform functionality and mobile computing.<br />

Ongoing Work<br />

Research is proceeding along two axes: evaluating IMMEDIATE in an actual distance learning course, and reengineering<br />

the prototype to support mobile learning and low-cost hardware.<br />

Preparations are underway to trial a further-refined learning computer in the distance teaching at the university level<br />

of Maori and English as second languages. The trials provide opportunities to evaluate its pedagogical effectiveness<br />

with a particular emphasis on assessing the learning support and search facilities. They also provide opportunities for<br />

refining and testing IMMEDIATE's course authoring and management tool.<br />

IMMEDIATE implements the learning computer as an application that is installed on top of the Windows operating<br />

system on a specific computer. However, its anybody, anywhere, anytime goal would be better met if students were<br />

not confined to using their own computer but could use any available one. As a first step in this direction we are re-<br />
