Enhancing web-based adaptive learning with colored timed petri net

One of the issues for Web-based learning applications is to adaptively provide personalized instructions for different learning activities. This paper proposes a high level colored timed Petri Net based approach to providing some level of adaptation for different users and learning activities. Examples are given to demonstrate how to realize adaptive interfaces and personalization. Future directions are also discussed at the end of this paper.

Understanding the ontological requirements for collaborative web-based experiential learning

The challenge of human-computer interaction forces educationalists to think of new ways to understand the social, historical and contextual nature of learning. Discussion and exchange of ideas enable learners to learn together. However, the granularity of the Webbased learning context is extensive; consequently, e- Courseware design faces new dilemmas. Only through targeted research will it be known with any certainty whether Web-based learning gives rise to a new type of learning dissonance [1]. It has been proposed that converged theoretical paradigms that underpin particular digitised or context-mediated learning systems are forcing learners into new ways of thinking [2]. This paper presents an overview of the plans for an experimental project designed to understand the ontological requirements for experiential instructional environments. This project is a joint research initiative involving three Universities in the Asia/Pacific region. Results will be used to inform educationalists interested in developing instructional strategies for a global community.

Developing wikis to foster web-based learning communities : an iterative approach

This paper discusses ongoing research at Deakin University, which focuses on developing wikis to foster web-based learning communities. Research to date has used wikis to facilitate collaborative icebreaker exercises, discussions, and to create knowledge repositories. Student feedback has contributed to the iterative revision of the wiki interface, the icebreaker exercise and the development of new tasks for students to complete using the wiki. The analysis and discussion of the experiments presented in this paper focuses on usage trends such as the signature, viewing and editing patterns exhibited by the student cohort. The community building potential of wikis is discussed, highlighting the specific wiki features that can be used to foster a sense of community in a web-based learning environment. Finally, issues surrounding the development of web-based learning communities, which have emerged through the wiki study, are discussed and future directions are outlined.

Adopting web-based learning and teaching: a case study in higher education

Most universities worldwide are becoming distance education providers through adopting web-based learning and teaching via the introduction of learning management systems that enable them to open their courses to both on- and off-campus students. Whether this is an effective introduction depends on factors that enable and impede the adoption of such systems and their related pedagogical strategies. This study examines such factors related to adopting a learning management system in a large multicampus urban Australian university. The research method used case study approaches and purposively selected the sample consisting of innovative teaching academics from across the university, who used web-based approaches to teach both on- and off-campus learners. The data were analyzed using a combination of Rogers' theory of diffusion of innovations and actor-network theory and revealed a series of enabling and impeding factors faced by pioneering technology-adopter teaching academics, some of which are technology related while others are policy related and common to large multicampus institutions. The study found that safe adoption environments recognizing career priorities of academics are a result of the continuous negotiation between the evolving institution and its innovative and creative staff. The article concludes with a series of conditions that would form a safe, enabling, and encouraging environment for technology-adopter teaching academics in a large multicampus higher education setting.

Accommodating learner diversity in web-based learning environments: imperatives for future developments

In this article, we focus on the use of Web-based learning environments for university students. We draw on an evaluation of an online environment that was developed to supplement face-to-face components of an undergraduate education unit in an Australian university. We explore learners' affective responses to this environment, finding that students' responses were often related to their familiarity with the learning environment, their skills and confidence with computer technology, and their preferred learning styles. It is not surprising to us that different students experienced the environment differently as this is the foundation of constructivist and socio-cultural understandings of learning. Yet, the models that currently predominate in the provision of online learning environments in universities offer very little in terms of responding and adapting to students' individual needs and preferences. Instead, online Web-based learning environments are most often designed to anticipate an average, or sometimes ideal, learner. We argue that designing for an imagined average or ideal learner does not adequately respond to the challenge of accommodating learner difference. If hopes for student-centred education are to be realised, future technological and pedagogical developments in online course provision need to be sophisticated enough to respond and adapt to individual students' needs and preferences across a wide range of variables.

Challenges of web-based learning environments: are we student-centred enuf?

The last decade has seen a phenomenal growth in the use of the Web in university education, with various factors influencing the adoption of Web-based technology. The reduction of government funding in the higher education sector has forced universities to seek technological solutions to provide courses for a growing and increasingly diverse and distributed student population [13,14]. Another impetus has been a shift in focus from teacher-centred to learner-centred education, encouraging educators to provide courses which enable students to manage their own learning [6]. In this paper we discuss challenges associated with the design and provision of Web-based learning environments that are truly student-centred. We draw on interview and questionnaire data from an evaluation study to raise issues surrounding the provision of online environments that meet learners' needs. We discuss the challenges of catering for the needs of different learners and the challenges associated with helping students to make the transition into new online learning environments.

Developing a web-based information resource for palliative care : an action-research inspired approach

Background : General Practitioners and community nurses rely on easily accessible, evidence-based online information to guide practice. To date, the methods that underpin the scoping of user-identified online information needs in palliative care have remained under-explored. This paper describes the benefits and challenges of a collaborative approach involving users and experts that informed the first stage of the development of a palliative care website.

Method : The action research-inspired methodology included a panel assessment of an existing palliative care website based in Victoria, Australia; a pre-development survey (n = 197) scoping potential audiences and palliative care information needs; working parties conducting a needs analysis about necessary information content for a redeveloped website targeting health professionals and caregivers/patients; an iterative evaluation process involving users and experts; as well as a final evaluation survey (n = 166).

Results : Involving users in the identification of content and links for a palliative care website is time-consuming and requires initial resources, strong networking skills and commitment. However, user participation provided crucial information that led to the widened the scope of the website audience and guided the development and testing of the website. The needs analysis underpinning the project suggests that palliative care peak bodies need to address three distinct audiences (clinicians, allied health professionals as well as patients and their caregivers).

Conclusion : Web developers should pay close attention to the content, language, and accessibility needs of these groups. Given the substantial cost associated with the maintenance of authoritative health information sites, the paper proposes a more collaborative development in which users can be engaged in the definition of content to ensure relevance and responsiveness, and to eliminate unnecessary detail. Access to volunteer networks forms an integral part of such an approach.

Web-based mathematics : student perspectives

This paper presents the results of a survey conducted with students (N=97) whose teachers have used the Web in their mathematics classes. The survey looked at students’ attitudes towards learning mathematics and their responses to the use of the Internet for learning mathematics. Factor analyses were used to determine the constructs that underlie the survey. Indices formed were used to explore their relationships with each other and with other variables. Interview findings were able to support and lend insight into some of these results.

The healthy child citizen: biopedagogies and web-based health promotion

The health of children in affluent economies has become closely tied to the ideal of a normative body weight achieved by monitoring and balancing diet and physical activity. As a result, the education of young people on how to avoid becoming fat begins at an early age through the language and practices of families, the messages embedded in children’s media, and through formal schooling. In this paper we use the concept of biopedagogies to investigate how discourses that connect food, the body and health come together on Internet websites to instruct children on how they should come to know and act on themselves in order to be(come) healthy bio-citizens.
