Learning to detect texture objects by artificial immune approaches

This paper introduces a novel method to detect texture objects from satellite images. First, a hierarchical strategy is developed to extract texture objects according to their roughness. Then, an artificial immune approach is presented to automatically generate segmentation thresholds and texture filters, which are used in the hierarchical strategy. In this approach, texture objects are regarded as antigens, and texture object filters and segmentation thresholds are regarded as antibodies. The clonal selection algorithm inspired by human immune system is employed to evolve antibodies. The population of antibodies is iteratively evaluated according to a statistical performance index corresponding to object detection ability, and evolves into the optimal antibody using the evolution principles of the clonal selection. Experimental results of texture object detection on satellite images are presented to illustrate the merit and feasibility of the proposed method.

Continuous improvement through shared understanding : reconceptualising instructional design for online learning

Many Australian tertiary institutions provide support for academic staff in the design and development of online teaching and learning resources, often employing a centralised unit staffed with educational and instructional designers, multimedia and online developers, audio/video producers and graphic artists. It is not unusual for these units to have evolved from print-based distance education providers and consequently the design and development processes inherent within those units are often steeped in ‘traditional’ sequential instructional development models. We argue that these models are no longer valid for effectively working with academic staff given the dynamic nature of online learning environments and the diversity of skills to implement effective online learning. This paper therefore presents an extended instructional design model in which the development cycle for online teaching and learning materials uses a scaffolding strategy in order to cater for learner-centred activities and to maximise scarce developer and academic resources. The model also integrates accepted phases of the instructional development process to provide guidelines for the disposition of staff and to more accurately reflect the creation of resources as learning design rather than instructional design. It is a model that builds on instructional design processes and integrates concepts of team-based development, shared understanding and the development of relevant communities of practice.

E-learning development in higher education : maximising efficiency : maintaining quality

Many tertiary institutions in Australia provide support to develop online teaching and learning resources, an environment characterised by demands from students for quality face-to-face and distance education, staff concern over workloads, institutional budgeting constraints and an imperative to use management systems. There also remains a legitimate focus on using online learning to facilitate new learning strategies within a complex social setting. This paper presents an extended instructional design model in which the development cycle for online teaching and learning materials uses a scaffolding strategy in order to cater for learner-centred activities and to maximise scarce developer and academic resources. The model also integrates accepted phases of the instructional development process to provide guidelines for the disposition of staff and to more accurately reflect the creation of resources as learning design rather than instructional design.

Enhancing instructional development processes for e-learning

This paper presents an extended instructional design model in which the development cycle for online teaching and learning materials uses a scaffolding strategy in order to cater for learner-centred activities and to maximise scarce developer and academic resources.

Designing blended learning in higher education : the neomillenial learner and mediated immersion

Blended learning as a term and a learning approach is still being refined, at times debated as a legitimate area of research, at times seen as the answer to the conundrum and challenges of the digital learner. Is it the Emperor’s new clothes? As Morrison (2003) suggests, blended learning could be seen as an uncertain or unsure strategy, or alternatively a way to find a solution to promises given for e-learning. Three case studies within this paper explore the possibilities of e-learning within a work-based framework. Elements of ‘neomillenial learning styles’ (Dede in Educause Quarterly vol 28 No 1 2005) reflected by students in postgraduate coursework programs provided the challenge and stimulation of designing and facilitating e-learning components, incorporating experiential or action learning with ‘associational’ approaches rather than linear ones. The journey to virtual simulations such as the postgraduate Newlandia incorporates the learner perspective, or how to activate neomillenial learning styles; blended learning with online and face-to-face community activist groups working for solutions to a water problem; and a virtual scenario which can appeal to and engage an internationalised user group. Do Dede’s neomillenial learners synthesise and process experiences rather than (or as well as) information? Is this mediated immersion a part of Newlandia’s applicability to the modern learner? The student teams of community activists and project managers described in the case studies incorporate a potent mix of learning styles, nationalities and backgrounds, expectations, interpersonal and technical skills and indicate a trend in millennial learners towards a community of knowledge which is collaborative, mobile and group-focused.

School innovation in science: improving science teaching and learning in Australian schools

School Innovation in Science is a major Victorian Government initiative that developed and validated a model whereby schools can improve their  science teaching and learning. The initiative was developed and rolled out to more than 400 schools over the period 2000-2004. A research team worked with 200+ primary and secondary schools over three years, supporting them in developing new initiatives in science, and monitoring the impact on school and classroom practice, and student outcomes. The research effort underpinning the development phase included the development and validation of a set of components describing effective teaching, the refinement of a school and teacher change strategy, the development of instruments to monitor teacher classroom practice and a variety of student outcomes, and the development of insights into the change process using questionnaires, observations, and interviews across four years. This paper describes the project and its major outcomes, and raises a number of issues concerning the nature of school and teacher change, pedagogy, school and community, and student learning, and the way these interact. A number of research issues are raised by the size and developmental nature of the project, the range of research methods, and the different audiences served by the research. The issue of sustainability of such system-wide change initiatives is discussed.

Investigating the 'integrated' in work-integrated learning.

Work-integrated learning (WIL) is an educational strategy in which students undergo conventional academic learning with an educational institution, and combine this with some time spent in a workplace relevant to their program of study and career aims. It goes under a number of names internationally; sandwich degree (Ward & Jefferies, 2004); cooperative education; and internships (Groenewald, 2004; Sovilla & Varty, 2004; Walters, 1947). The name cooperative education reflects the tripartite nature of WIL in which the student, tertiary education institution (TEI), and workplace work together collaboratively to develop a comprehensive skill set in students (Coll, 1996). Recently the World Association for Cooperative Education added 'integrated' in a by-line to its name to reflect a broader perspective of the nature of cooperative education that can include capstone programs [practicum], internships, sandwich degrees, and work-based learning via industry projects (Franks & Blomqvist, 2004). A key aspect of WIL is the notion that it entails the integration of knowledge and skills gained in the educational institution and in the workplace. It is the integration aspect of WIL that distinguishes it from workplace learning (i.e., simply what a student or employee learns in the workplace, see Boud & Falchikov, 2006).

Eames (2003) notes that whilst there is a rich literature on the success of WIL programs, such research is almost entirely concerned with what he terms 'operational outcomes', such as benefits for students (Dressler & Keeling, 2004), employers (Braunstein & Loken, 2004), and TEIs (Weisz & Chapman, 2004). For example, it has been reported that compared with conventional graduates students who participate in WIL programs gain employment more easily, fit in better in the workplace, advance more rapidly in their careers, and so on (Dressler & Keeling, 2004). However, there is a serious paucity of research into what WIL students learn, how they learn, whom they learn from (Eames & Bell, 2005), and how the learning might be better facilitated and supported. A key purpose of work-integrated learning is the notion of providing graduates with a comprehensive skill set desired by potential employers. However, the literature notes that it is problematic for tertiary education providers to provide students with such skills, especially behavioural skills; the so-called soft skills (Burchell, Hodges & Rainsbury, 2000; Coll & Zegwaard, 2006). In what way does the student take what he or she has learned into the workplace, and conversely in what way does what the student learns in the workplace become related to, or incorporated into, the next phase of academic learning when he or she returns to the TEI after completing a work-placement?

Mathematical power of special-needs pupils : an ICT-based dynamic assessment format to reveal weak pupils' learning potential

This paper reports a study aimed at revealing special-educational-needs pupils' learning potential by means of an ICT-based assessment including a dynamic visual tool that might help pupils when solving mathematics problems. The study focused on subtraction problems up to 100, which require 'borrowing'. These problems, in which the value of the ones-digit of the subtrahend is larger than the ones-digit of the minuend, are known as a serious difficulty for weak pupils in mathematics. Seven of such problems from a standardised test were placed in the ICT environment. Data were collected from two test conditions: the standardised written test format and the ICT version of the test items including the tool that provided pupils with a set of virtual manipulatives. The 37 pupils involved in the study were 8–12 years old and from two special-education schools in the Netherlands. Comparison of the performance scores in the two formats showed that an ICT-based assessment format, including a dynamic visual tool, can reveal weak pupils' learning potential and strategy use. The study also pointed out that 'partial-tool use', ie, not carrying out the complete subtraction operation with the tool, can provide sufficient support to find the correct answer.

Action research in higher education : the advancement of university learning and teaching

This thesis aims to contribute to the improvement and advancement of university learning, teaching, and staff development; to integrate educational theory and the practice of university teaching; and to contribute to the establishment of a new, emerging paradigm in higher education. The strategy towards achieving these aims comprises (1) an alternative research methodology in the interpretive, non-positivist paradigm; (2) an integrated framework drawing on a variety of previously unrelated theories to form an alternative model of university education; and (3) reference to the dialectical relationship between educational theory and teaching practice and their integration through action research in higher education. The thesis is not so much a critique of the traditional paradigm and of existing functionalist-structuralist approaches to higher education, but more a development and clarification of an alternative, dialectical, human action approach to higher education. The original contribution of this thesis to the theory and practice of higher education lies in the development (1) of an alternative model of university education based on an integration of previously unrelated domains of theory; (2) of a theoretical model of professional development as action research (the CRASP Model: Critical attitude, Research into teaching, Accountability, Self-evaluation, Professionalism); and (3) of action research projects in higher education. Action research is research by the university teachers themselves into their teaching practice, i.e. into problems of the curriculum and student learning. The case studies included in and appended to this thesis show that in one educational setting at least it was possible to improve and advance university learning and teaching through action research. The evidence for this advancement is provided in a number of previously published case studies compiled in the Appendix.

A problem-based learning project supported by the internet

This case study looks at how bank sites with interactive calculators can be used to enhance directed investigations of students in a Mathematics Studies course. In the course of these investigations, students access simulated contexts which enabled them to have a feel of how they would spend money in the real world. This case study reveals the confidence of students in carrying out searches and transferring data, learning about bank calculators and their role in real life, how hidden costs are incorporated into loans and being able to validate what is presented in these calculators with their own calculations. This case study also highlights the perceptions of the teacher regarding this strategy in teaching this topic and the areas that need improvement. This paper analyses what has happened in the teaching and learning process and endeavours to shed some light into how the Internet can be used to promote a quality mathematics education.

Towards a cyberspatial pedagogy : exploring synchronous online learning potentials

It has been a quarter of a century since William Gibson (1984) coined the term cyberspace in his seminal science fiction novel Neuromancer. Subsequently, a proliferation of online teaching technologies have emerged supporting Virilio’s (1991) contention that, “time and space have ceased to function as meaningful dimensions to human thought and action.” The aim of this presentation is to discuss and demonstrate the innovative modification of an online, synchronous learning environment, Elluminate Live! (eLive), which allows participants to transcend the spatial dimension. Specifically, we present an example of good practice which aimed to enhance student engagement by implementing a structured online tutorial series which replicated the entire first year psychology on-campus tutorial series in the eLive environment. We discuss Student Evaluation of Teaching and Units (SETU) results which support the utility of this pedagogic strategy. Finally, we outline various challenges for the virtual teacher who wishes to implement a structured learning program in the eLive environment.

Continuous professional learning through school based strategic planning

There is ample evidence that in many countries school science is in difficulty, with declining student attitudes and uptake of science. This presentation argues that a key to addressing the problem lies in transforming teachers’ classroom practice, and that pedagogical innovation is best supported within a school context. Evidence for effective change will draw on the School Innovation in Science (SIS) initiative in Victoria, which has developed and evaluated a model to improve science teaching and learning across a school system. The model involves a framework for describing effective teaching and learning, and a strategy that allows schools flexibility to develop their practice to suit local conditions and to maintain ownership of the change process. SIS has proved successful in improving science teaching and learning in primary and secondary schools. Experience from SIS and related projects, from a national Australian science and literacy project, and from system wide science initiatives in Europe, will be used to explore the factors that affect the success and the path of innovation in schools.

Simulation-based learning for control of complex conveyor networks

This research investigated the problem of path planning in complex conveyor networks. A reinforcement learning approach was applied to derive a control strategy for routing traffic. The derived strategy was verified in real world systems and was found to improve network performance by prioritising traffic flows and balancing network load.

Action learning through the use of enterprise resource planning system in construction management

Although information communication technology (ICT) tool is long regard as very useful in today’s engineering, architectural and construction management, organizations cannot just only simply operate based upon its origin, but also requires the on-going observation, controlling measures, monitoring aids, adding features and fine-tuning actions to such tool before the desirable outcome can be achieved. However, it is a very common phenomenon that organizations purchase the licensed “off-the-shelf-software” ICT package and customize it to suit their own requirements. Due to the incapability and inefficiency of such software and customization, the possible result is making such tool becomes not user-friendly and obsolete.

The purpose of this paper therefore, as part of the doctoral research, is to review and report those actions taken by a construction organization to enhance the performance of its Enterprise Resource Planning (ERP) system upon launching it since December 2002. Such actions include: improving data inputting method; removing the transition bottleneck; introducing crystallization function; revising the organization’s “Delegation and Limits of Authority”; publishing the “League Table” amongst users; integrating the 3D Modeling into the system and adopting the “Resources Requirement Planning”.

Whilst the ultimate goals of this system are well beyond the time limit of the research project, an obvious interim result, achieved by this case studied organization, was winning a landmark project worth HK$5 billion after the ERP system was functioned effectively. The experience and success of this organization can be borrowed by those companies which are planning to adopt information technology (IT) strategy and use ICT tool in the architectural management system.
