An information architecture for courseware validation

A lack of pedagogy in courseware can lead to learner rejec- tion. It is therefore vital that pedagogy is a central concern of courseware construction. Courseware validation allows the course creator to specify pedagogical rules and principles which courseware must conform to. In this paper we investigate the information needed for courseware valida- tion and propose an information architecture to be used as a basis for validation

Model-driven description and validation of composite learning content

Authoring of learning content for courseware systems is a complex activity requiring the combination of a range of design and validation techniques. We introduce the CAVIAr courseware models allowing for learning content description and validation. Model-based representation and analysis of different concerns such as the subject domain, learning context, resources and instructional design used are key contributors to this integrated solution. Personalised learning is particularly difficult to design as dynamic configurations cannot easily be predicted and tested. A tool-supported technique based on CAVIAr can alleviate this complexity through the validation of a set of pedagogical and non-pedagogical requirements. Courseware validation checks intra- and inter-content relationships and the compliance with requirements and educational theories

Model-driven transformation and validation of adaptive educational hypermedia using CAVIAr

Authoring of Adaptive Educational Hypermedia is a complex activity requiring the combination of a range of design and validation techniques.We demonstrate how Adaptive Educational Hypermedia can be transformed into CAVIAr courseware validation models allowing for its validation. The model-based representation and analysis of different concerns and model-based mappings and transformations are key contributors to this integrated solution. We illustrate the benefits of Model Driven Engineering methodologies that allow for interoperability between CAVIAr and a well known Adaptive Educational Hypermedia framework. By allowing for the validation of Adaptive Educational Hypermedia, the course creator limits the risk of pedagogical problems in migrating to Adaptive Educational Hypermedia from static courseware

An information architecture for validating courseware

Courseware validation should locate Learning Objects inconsistent with the courseware instructional design being used. In order for validation to take place it is necessary to identify the implicit and explicit information needed for validation. In this paper, we identify this information and formally define an information architecture to model courseware validation information explicitly. This promotes tool-support for courseware validation and its interoperability with the courseware specifications

The use of innovation and practice profiles in the evaluation of curriculum implementation

Most generic curriculum reform efforts have to deal with a gap between the innovative aspirations of the initial designers and the daily reality of the intended audience of teachers. That tension is not alarming in itself. One might even say that without it no compelling reason for starting development work would exist. Unfortunately, many evaluation studies on the implementation and impact of curriculum development projects show that this discrepancy does not decrease over time. Apparently, not much improvement is made in detecting and reducing potential implementation problems.\ud This article presents some conceptual and instrumental guidelines for dealing with these problems, focusing on the use of `profiles¿ during evaluation of curriculum materials.\ud The paper starts with an introduction on the functions of exemplary curriculum materials and their possible representations, on the long road from original designers¿ ideas to effects of student learning. Next, we will explain the concepts of innovation and practice profiles. We will then provide guidelines for the development and use of such profiles, based on previous research experiences, and illustrated with some specific examples. Finally, we will reflect on the advantages and limitations of working with profiles

Automatic validation of learning object compositions

Course construction using reusable learning objects is becoming ever more popular due to its’ efficiency. The course creator who uses this methodology may face problems due to the fact that he or she is not as intimately involved in the creation of every element of the course. In this paper we discuss one such problem faced by course creator known as “the competency gap”. Here, we define the competency gap, explain how it can be identified and suggest ways of correcting the problem

The use of animated agents in e‐learning environments: an exploratory, interpretive case study

There is increasing interest in the use of animated agents in e‐learning environments. However, empirical investigations of their use in online education are limited. Our aim is to provide an empirically based framework for the development and evaluation of animated agents in e‐learning environments. Findings suggest a number of challenges, including the multiple dialogue models that animated agents will need to accommodate, the diverse range of roles that pedagogical animated agents can usefully support, the dichotomous relationship that emerges between these roles and that of the lecturer, and student perception of the degree of autonomy that can be afforded to animated agents

A hybrid method for the analysis of learner behaviour in active learning environments

Software-mediated learning requires adjustments in the teaching and learning process. In particular active learning facilitated through interactive learning software differs from traditional instructor-oriented, classroom-based teaching. We present behaviour analysis techniques for Web-mediated learning. Motivation, acceptance of the learning approach and technology, learning organisation and actual tool usage are aspects of behaviour that require different analysis techniques to be used. A hybrid method based on a combination of survey methods and Web usage mining techniques can provide accurate and comprehensive analysis results. These techniques allow us to evaluate active learning approaches implemented in form of Web tutorials
