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.

Futures in education

Futures education (FE) in a rapidly changing world is critical if young people are to be empowered to be proactive rather than reactive about the future. Research into young people's images and ideas of the future lead to the disturbing conclusion that, for many, the future is a depressing and fearful place where they feel hopeless and disempowered. On the other hand, as Richard Slaughter writes, 'young people are passionately interested in their own futures, and that of the society in which they live. They universally 'jump at the chance to study something with such intrinsic interest that also intersects with their own life interests in so many ways'. FE explicitly attempts to build on this interest and counter these fears by offering a profound and empowering set of learning strategies and ideas that can help people think and act critically and creatively about the future, without necessarily trying to predict it. Futures educators have, over the past decades, developed useful tools, ideas and a language for use with students of all ages to enable them to develop foresight literacy. Most of us tend to view the future as somehow beyond the present and rarely consider how decisions and choices made today profoundly affect not just one fixed future but any number of futures. The underlying goal of FE is to move from the idea of a single, pre-determined future to that of many possible futures, so that students begin to see that they can determine the future, that they need not be reactive and that they are not powerless. How does one do that? Ideas include, but are not limited to: timelines and Y-diagrams, futures wheels and mind maps, and 'Preferable, possible and probable' futures - a.k.a. the 3Ps. Current Australian curricula present education about the future in various implicit or explicit guises. A plethora of statements and curriculum outcomes mention the future, but essentially take 'it' for granted, and are uninformed by FE literature, language, ideas or tools. Science, the humanities and technology tend to be the main areas where such an implicit futures focus can be found. It also appears in documents about vocational education, civics and lifelong learning. Explicit FE is, as Beare and Slaughter put it, still the missing dimension in education. Explicit FE attempts to develop futures literacy, and draws widely upon futures studies literature for processes and content. FE provides such a wide range of ideas and tools that it can be incorporated into education in any number of ways. Programs in two very different schools, one primary and one secondary, are described in this article to provide examples of some of these ways. The first school, Kimberley Park State Primary School in Brisbane, operates with multi-age classrooms based on a 'thinking curriculum' developed around four organisers: change, perspectives, interconnectedness and sustainability. The second school, St John's Grammar School in Adelaide, is an independent school where FE operates as an integrated approach in Year Seven, as a separate one-semester subject in Year Nine and in separate subjects at other levels. Teachers both at Kimberley Park and St John's are very positive about FE. They say it promotes valuable and authentic learning, assists students to realise they have choices that matter and helps them see that the future need not be all doom and gloom. Because students are interested in the Big Questions, as one teacher put it, FE provides a perfect opportunity to address them, and to consider values that are fundamental for them and the future of the planet. Like any innovation, the long-term success of FE in schools depends on an embedding process so that the innovation does not depend on the enthusiasm and energy of a few individuals, only to disappear when they move on. It requires strong leadership, teacher knowledge, support and enthusiasm, and the support and understanding of the wider school community.

Supporting adaptive learning in hypertext environments : a high level timed Petri net-based approach

A problem for hypertext-based learning application is to control learning paths for different learning activities. This paper first introduces related concepts of hypertext learning state space and high level Petri Nets (PNs), then proposes a high level timed PN based approach used to providing kinds of adaptation for learning activities by adjusting time attributes of targeted learning state space. Examples are given while explaining ways to realising adaptive instructions. Possible future directions are also discussed at the end of this paper.

Perceptions of the value of site visits in assisting undergraduate learning

This study evaluates the usefulness of site visits in assisting the learning experience of undergraduate students. The research is based on a survey of undergraduates students enrolled in built-environment courses in property and construction. Past research has shown that it is becoming more difficult to provide students with access to building sites to provide learning experiences. While students were positive about the benefits of real site visits, universities have been encouraged to develop virtual approaches to teaching construction technology using photographs, movies and computer simulations.

This strategic research investigates the perceptions of students towards a number of different site visits each with particular characteristics. This was done to examine the most effective use of real site visits within an undergraduate course. The results identified that some aspects of construction technology could be easily replaced by computer simulations and the like. However, other aspects of the curriculum are more effectively taught by retaining real site visits. The research was intended to provide a more structured approach to determining the value of site-based learning in construction related courses.

Technology adoption : voices of teaching academics, educational designers and students

This folio presents three studies (a dissertation and two electives) which use qualitative case study methodologies to investigate technology adoption from three perspectives. Central to all three studies is the study context of Monash University. The Dissertation explores adoption of web-based learning and teaching approaches from the perspective of teaching academics as they incorporate these to facilitate their students’ learning. The study investigates teaching academics’ reasons for adopting these new technologies, the factors that influenced their adoption decisions, and the challenges they were confronted with, including the contributing factors that impacted on their adoption decisions. The study shows that while contextual factors such as power and politics of the school, department, faculty and the institution impact on adoption, supportive organisational infrastructures and policy frameworks are necessary to encourage adoption, including wider adoption. In turn, on going staff development, adoption of new work practices and being adaptive to changing work environments are key demands made on teaching academics as a result of adopting web-based teaching approaches. Elective 1, a smaller study, leads on from the dissertation and examines the impact of technology adoption on the evolving role of educational designers. The study identifies the educational designers’ role change in assisting teaching academics to move from more conventional forms of teaching to more technology based learner-centred collaborative models. An important aspect of the study is the managers’ perspectives of this role in a university that has adopted a strong flexible learning and technology policy. The findings show that educational designers now work as project managers in larger teams consisting of a wider range of professionals, their expanded role in introducing technology into learning designs, providing staff development in the area, and giving technical help including advice on copyright and intellectual property issues. Elective 2 explores student readiness to adopt these technologies for learning. The study is designed to achieve an understanding of three broad categories of learners from a first year design unit: (1) South East Asian and East Asian students, (2) all other international students, and (3) local Australian students are studied to examine their readiness for modes of learning that are flexible; their approaches to study in a creative discipline area; and their openness to using technology. Findings of the study are discussed under the key themes – dependence on the teacher and classroom environment, flexible learning and working alone, structure, communication and work patterns. The study concludes by discussing the possible cultural attributes that have an impact on the learning. The three studies found that the institution, its people, structures and processes must all adapt, evolve and grow in order to provide effective, engaging, student-centred web-based learning environments. Students in turn must be enabled to manage their study, make use of the technologies and maximise their learning experience. The findings revealed the stage of technology use reached at Monash University at the time of the study through the voices of the teaching academics, educational designers and students.

Telecommunication technology and the professional development of teachers : challenge and opportunity

The thesis explores an effective model for using the internet in a distance training program for secondary school teachers. The professional development program, the dissertation, titled The Virtual University: Professional development for teachers, was initiated based on aspects of telecommunication technology and the professional development for Thai school teachers. The question of this program was “How could information technology be used in developing an appropriate professional development model for Thai teachers?” Prior to the project, the four research studies were conducted to formulate the related base line information and supported framework for the program development. The four researches are: (1) Telecommunication Technology in Thai Schools, (2) The Role of University on Science Teachers Development, (3) Computer Education Curriculum for Student Teachers: Theory and Practice, and (4) Teachers’ Perceptions of the Academic Link Project Between Schools and Universities for Teacher Professional Development. The first research study provides the information about the necessary basic factors for change in Thai secondary schools and the new insights and understandings about change in Thai schooling. The major findings were the understandings about teachers’ need for professional development, the available support in Thai school for professional development, and the limitations of professional development of teachers. The second research study provides the information about the roles of university faculty on initiation and operation of science teacher development programs, science teaching and learning resources centers, science instructional media design and production services, science teaching clinics, and science teachers’ associations. The third research study provides the conceptual framework for both preservice and inservice curriculum development program for teacher development. The last research study provides a base of descriptive information about the perspectives of school teachers towards the academic link project between schools and universities and the partnership which can assist in its establishment. The findings of these four research tasks were used for the formation of the framework of the dissertation. The EDNET Project, an example of teachers’ professional development through the information technology based training, was developed and implemented with ten school teachers in Khon Kaen.

Microarray classification using statistical learning and decision tree algorithms

This considers the challenging task of cancer prediction based on microarray data for the medical community. The research was conducted on mostly common cancers (breast, colon, long, prostate and leukemia) microarray data analysis, and suggests the use of modern machine learning techniques to predict cancer.

Using information and communications technology in higher education

A folio-based doctoral study comprising a dissertation, a major literature review, and a website. The dissertation identified key dimensions of blended learning environments created by the teachers in the study. These environments were characterised by different media blends and learning activities underpinned by resource-based learning approaches to teaching and learning.

Community resilience, climate change, sustainability & engagement : adventures in creative project-based education on the Eyre Peninsula

Teaching sustainability ethics and creative practical technological applications holistically, in a multi-disciplinary ethos, with real community engagement is fraught with pedagogical and logistical issues. This paper reviews a highly community-acclaimed tertiary course/project, offered at the School of Architecture, Landscape Architecture & Urban Design at the University of Adelaide, undertaken on the Eyre Peninsula in 1st semester 2009. The course successfully enhanced student appreciation of rural community capacity building and economic fragility issues while undertaking a project-based approach to interrogating and working with rural communities to devise and demonstrate potential micro-relevant design and planning initiatives that could strengthen community resilience, climate change adaptiveness, and validate natural resource management aims within townships. The project involved some 120 students in 6 host communities through 6 local municipalities with the full support of the Natural Resource Management (NRM) Board and Local Government Association (LGA).

The paper reviews the project, its historical evolution, aims, objectives, learning strategies, community aspirations and outcomes, and positions such against various professional education accreditation frameworks. The methodological learning process, including its philosophical, pedagogical and instruments outcomes are reviewed and interrogated. The student learning outcomes, University reputation impact, and community impact, professional practice knowledge and skill attributes, and instrumental outcomes are also reviewed drawing upon evidence derived from extensive meetings, questionnaire surveys, synergistic NRM-sponsored research projects, student evaluation of teachings (SELTS), and local media coverage of the project.

The project has received applause from the Australian Institute of Architects (AIA) and Australian Institute of Landscape Architects (AILA), and preliminary endorsement from the Planning Institute of Australia (PIA), as being integral to the School’s curriculum that achieves their professional accreditation expectations of key learning experiences relevant to climate change, master planning and design, and community engagement. The project offers a possible educational model that enriches student experience and learning and addresses recent generic university community engagement policy expectations.

The value of experiential learning for providing a contextual understanding of the construction process

This research investigates effectiveness of real site visits within an undergraduate course. Experiential learning is a process of providing education, based on the experiences and observations of real-world examples. Some of the theory of experiential learning has been used to examine whether site visits assist the students learning experience.

The results of the research show that students generally have a positive attitude towards site visits and see them as beneficial. Although the study identified that some aspects of construction technology could be easily replaced by computer simulations and the like, other aspects of the curriculum are more effectively taught by retaining real site visits. The research was intended to provide a more structured approach to determining the value of site-based learning in construction-related courses.

The social side of social media : technology or collaboration?

This paper discusses how course design may draw upon social media in order to teach students appropriate skills for a network society in the context of team-work based learning. The emphasis is not upon web 2.0 and social media as inherently suited to providing educational solutions, but upon the ways in which they can be adapted by course designers within the framework of explicit learning objectives. More specifically, we provide a case study of how the use of social media in a blended or wholly-online learning environment provides affordances for team-based collaborative learning, especially when incorporated within a course design that encourages independent, self-directed and authentic learning. This paper argues we need to assess the social aspects of social media, rather than upon the technological, that is, avoid the fetishisation of 'apps,' through the creation of assessment that alternately foregrounds a critical appraisal of web 2.0 technologies and places onus upon the students to develop, with guidance, teamwork skills and processes. We provide an example of how it is possible to integrate web 2.0 technologies into their learning processes and assessment, in order to teach about the realities of collaborating with others in small teams in a work environment increasingly mediated by the Internet. In order to achieve these learning outcomes, course design needs to balance scaffolding with the need to place the imperative for learning specific content and skills upon the students, the latter through the provision of assessment outcomes and resources that the students need to work towards together.
