Set-level problems are as important as instance-level problems. The core in solving set-level problems is: how to measure the similarity between two sets. This paper investigates data-dependent kernels that are derived directly from data. We introduce Isolation Set Kernel which is solely dependent on data distribution, requiring neither class information nor explicit learning. In contrast, most current set-similarities are not dependent on the underlying data distribution. We theoretically analyze the characteristic of Isolation Set-Kernel. As the set-kernel has a finite feature map, we show that it can be used to speed up the set-kernel computation significantly. We apply Isolation Set-Kernel to Multi-Instance Learning (MIL) using SVM classifier, and demonstrate that it outperforms other set-kernels or other solutions to the MIL problem.

This paper looks at apprenticeship learning and training from a new standpoint – the psychological contract. The notion of the psychological contract is commonly used in the human resource management field to understand the nature of employment relationships. It has not previously been applied to apprenticeships in any systematic manner. This paper reports on a research project that applied a preexisting instrument to apprentices and employers and also included qualitative case studies in nine companies.

In this paper I report on a project designed to enhance student teacher engagement in learning by developing an explicit pedagogy of affective learning, traditionally ignored in teacher education as discipline-based studies have dominated the field. Strategies investigated are based on reading engaged on affective levels, intertwined with current approaches to academic reading, with metacognitive responses recorded by the students as part of student evaluation of their own learning. Reading has been structured around literature reading circles (affective reading component), and academic reading circles (professional reading component). The project uses strategy in relation to the identifiable stages in a teaching sequence which help students to realise a learning goal, so that they use learning strategies and respond to teaching strategies that scaffold their learning. The reading program pushes the boundaries of their discipline-based learning, engaging what Schön refers to as ‘indeterminate zones of practice’ as giving an affective dimension, having wider implications for student engagement in discipline-based units than straight academic encounters with discipline-based literature allows. The reading is designed to integrate discipline-based knowledge, the implications of this for professional lives, and the affective dimensions of professional practice. The results of this project indicate that, according to student evaluations, their capacities for self monitoring and self evaluation was enhanced at the same time as their own engagement with relevant literature deepened their understandings of issues that emerged from that engagement.

Our paper is based on our recently published NCVER project on Men's sheds in Australia, Learning through Community Contexts (Golding, Brown, Foley, Harvey & Gleeson, 2007), which showed that men';s sheds informally cater for non vocational, social, health, wellbeing and learning needs of mainly older men. We deliberately used unedited transcripts from the NCVER project in the form of narratives or stories to give the men an opportunity to speak for themselves about the benefits of participating in men's sheds. The paper highlights some of the limitations of the methodology used in the attempt to allow the men themselves to make sense of the benefits they experience and enjoy from participating in men's sheds as conveyed through their own voices.

At the University of Ballarat, pre-service teachers (PSTs) in their second year of the Bachelor of Education (P-10) are required to plan community-based teaching and learning in conjunction with school students, their teachers and schools along with community organisations. These requirements are in synergy with curriculum developments in schools and appear to be valued by them. While the transformative potential of community-based teaching and learning for teacher educators is acknowledged, there is a clear need for more research into the factors which underlie the success or otherwise of such approaches. In this paper, the implementation of community-based teaching and learning programs developed by pre-service teachers is examined for educational and organisational issues that shaped the outcomes for students. The paper highlights a number of consistent themes that throw light on factors that appear to affect the success of such pre-service courses. These insights contribute to the understanding of community-based pre-service teacher education curricula and pedagogies as an important and emerging area of interest.

Universities are challenged to seek methods to improve student learning. Leading edge technologies, such as podcasts, that put the focus on learner-chosen activities may be one way to accomplish this. This study explored student perceptions of podcasting as a learning and teaching tool in a first semester information systems course within an Australian university. Students were provided with a short podcast to supplement face-to-face lectures. Students were then surveyed to determine their perceptions of the impact of this podcast on their learning. A high number of respondents agreed that they used the podcast, that it increased their understanding of the lecture material and that it assisted their learning in the unit overall. The findings in this preliminary study lend support to the concept that podcasting can enhance learning when used as a supplement to traditional teaching methods.

Eligibility traces have been shown to substantially improve the convergence speed of temporal difference learning algorithms, by maintaining a record of recently experienced states. This paper presents an extension of conventional eligibility traces (compiled traces) which retain additional information about the agent’s experience within the environment. Empirical results show that compiled traces outperform conventional traces when applied to policy evaluation tasks using a tabular representation of the state values.

In this study more than 40% of the 355 student nurses who completed a pre-test, involving comparisons of decimal numbers, made errors that indicate an incomplete or incorrect conceptual understanding. This includes students who are sometimes able to achieve 100% on drug calculations tests. Seven test items with error rates of between 10% and 26% form the focus of our discussion. A sub-group of the students attended a one-hour remedial intervention using various physical materials to give conceptual meaning to decimal numbers. A matched post-test three months after the intervention, detected a statistically significant improvement for the intervention students but not for those who only practiced drug calculation procedures. Conceptual teaching for number sense is needed to underpin procedures.

Narrative or story telling has long been used to structure and organise human experience. In contrast to logical models of reasoning, narrative models enable complex situations to be understood and recalled by humans readily. In this work a narrative model is integrated into a logical reasoning model for the purpose of advancing a learning environment that promises to be engaging and effective. The narrative model includes a representation of the point of a story and a simple story grammar. The logical reasoning model is based on an argumentation model. The learning environment is designed to enable the automated generation of plausible scenarios that involves an intensive care unit nurse responding to a low oxygen level alarm.

Corio Bay Innovators, trading as dal Gourmet Café and Catering, is an innovative supported training and employment service that operates a gourmet catering service and two retail cafes in Geelong. Currently, dal has around forty staff who receive federal or state disability funding, and about half as many support staff. Rather than being seen as an agency providing supported employment, dal is regarded as a successful and competitive business that is very popular locally, and is in demand in the hospitality sector. Yet dal’s primary purpose is not the friendly service, great atmosphere, and delicious food, but the creation of a range of innovative employment opportunities in a caring work environment for adults who have been labeled as having disabilities. Most significant, however, is the extremely strong emphasis on inclusion in the local community, in combination with an actively supportive and empowering workplace. Staff at dal have voted that they do not want to be labelled as having disabilities but to have it noted that they have special needs. While the choice of such terminology may not necessarily be in line with current “politically correct” discourse, it is a choice that is respected at dal. It is a description worn with pride in difference and collective identification adopted by other oppressed communities and acknowledged by Meekosha (2000) and Barton (2003). While exploring dal as a model of best practice in training young people for the hospitality industry, this paper will explore the conflicts raised by contrasts between the voices of the staff at dal and the discourses of educators and trainers, in an attempt to develop a sustainable model for the future.

Narrative or story telling has long been used to structure and organise human experience. In contrast to logical models of reasoning, narrative models enable complex situations to be understood and recalled by humans readily. There is also some indication that narrative models represent the way in which jurors weigh up the veracity of legal evidence. In this work a narrative model is integrated into a logical reasoning model for the purpose of advancing a learning environment that promises to be engaging and effective. The narrative model includes a representation of the point of a story and a simple story grammar. The learning environment is designed to enable the automated generation of plausible scenarios representing a variety of family law property division cases told from the point of view of numerous characters.

Computer Algebra Systems (CAS) are powerful tools for both doing and learning mathematics. They may be used to perform algorithmic routines both quickly and correctly but harnessing this power in a manner which is effective for promoting learning is not trivial. Research undertaken with both secondary school and undergraduate students clearly indicates that, while students quickly come to appreciate the availability of CAS to check their answers, several key factors influence the development of their use of the facility of CAS to extend both access to mathematics and support learning of mathematical concepts. First, the institutional value which the technology is afforded influences the degree to which students are willing to apply themselves to the task of learning technical skills necessary to work with CAS. Second, the use of multiple representations may both increase students’ conceptual understanding and provide them with alternative methods through which to progress solution of problems. Finally, students need to be guided in judicious use of CAS. This will involve teaching students to be discriminating in their use of technology for functional purposes, that is, to find solutions to difficult or time consuming problems, and strategic in their use of CAS to explore patterns and link representations in order to gain greater insight into mathematical processes and concepts.

Networks have increasingly been recognised by educators as important in adult and vocational learning contexts, in that they have the capacity to help potential learners engage and become better connected with a wide range of learning organisations through their families, jobs and communities and also with opportunities for future learning and work. The importance of ‘being connected’, including through networks to and between learning organisations, has come into higher relief with a recent increase in theorising about aspects of social capital including learning networks, the growth of lifelong learning and an identification of the particular penalties associated with several forms of disengagement from learning for people of all ages. This paper begins with a scan of research literature on networks in adult and vocational learning. The paper identifies some new techniques involving networks, found by experience to assist in the process of adult and vocational learning research: particularly for identifying potential research interviewees within learning organisations and communities, strengthening relationships between learning organisations and identifying opportunities for future collaboration. It also provides some insights from new data on organisational networks derived from a number of recent research studies about learning networks in TAFE, adult and community education and public safety organisations in small and remote towns. The paper finally provides a number of tentative, general findings about the broader applicability of network theory to research and theories about learning in such contexts.

Increased access to university by students with different backgrounds and capabilities from those in the past has posed, and continues to pose, dilemmas for lecturers who seek effective ways of addressing the challenge of undergraduate literacy and learning. To this end, we have been engaged on a Committee for University Teaching and Staff Development (CUTSD) funded program that we call TULIP (Tertiary Undergraduate Literacy Integration Program) which focuses on the integration of tertiary literacy within content teaching as a means of enhancing student literacy. The broad aim of the TULIP Project was to build on collaborative and reflective teaching and learning partnerships between lecturers and students, between lecturers across two universities, and between lecturers in disparate disciplines. The project developed, trialed and evaluated a suite of learner-centred literacy strategies that comprise the TULIP Resource Kit which foregrounds the embeddedness of tertiary literacy within content teaching.

Adults in Australia have tended to return relatively recently to learning in patterns that are significantly different by gender. These patterns of gender segmentation for adults are particularly noticeable in the findings of recent research by the author into adult, community and vocational learning in small and remote towns in Victoria. The issues associated with such patterns form the basis of this exploratory paper.
