An active stereo vision-based learning approach for robotic tracking, fixating and grasping control

In this paper, an active stereo vision-based learning approach is proposed for a robot to track, fixate and grasp an object in unknown environments. First, the functional mapping relationships between the joint angles of the active stereo vision system and the spatial representations of the object are derived and expressed in a three-dimensional workspace frame. Next, the self-adaptive resonance theory-based neural networks and the feedforward neural networks are used to learn the mapping relationships in a self-organized way. Then, the approach is verified by simulation using the models of an active stereo vision system which is installed in the end-effector of a robot. Finally, the simulation results confirm the effectiveness of the present approach.

Vocational learners: testing readiness for online learning

McVay's (2000) Readiness for Online Learning questionnaire is tested for its potential value as an instrument to assess the readiness for online learning of technical level and of university level vocational learners. The research indicates that the instrument yields a reliable factor structure that is replicable across the two learner groups, and is interpretable in a context of broader research and theory on flexible learning. Although the reliability of the instrument and its items is acceptable for the university level sample, reliability was less than acceptable for the technical level learners. The utility of the instrument is discussed for each of these samples of learners.

Evidence for sustainable e-learning in quality online learning environments: a purposive approach to content analysis

This paper examines a methodology for establishing quality in online learning environments. For e-learning to be sustainable in flexible, open and distance learning, its value in learning must be able to be analysed. In the case of computer conferencing, one way to do this is with content analysis. This methodology is discussed with a review of current frameworks. These indicate that while some researchers and evaluators either use or modify existing frameworks, most researchers develop new ones, generally through the adaptation of existing theories, concepts or model, but in some cases through grounded theory approaches. The development and implementation of two frameworks are then discussed in detail. Both were developed to investigate and evaluate both collaborative learning and deep and surface learning as evidenced in computer conferences. Evidence of such learning attributes are precisely the elements of value in e-learning that can be shown through such a methodology. These attributes can then be integrated into courses developed for quality online learning environments.

An introduction to eRoadmapping : providing learning paths for students and empowering teachers

This paper reports on the development of an innovative teaching strategy: an eRoadmap.  Based on the theory of conceptual mapping, the eRoadmap provides an interactive, hierarchical structure for course delivery, using the readily accessible platform provided by Microsoft PowerPoint.  For the student, the eRoadmap provides a self-paced learning environment which encourages student engagement; for the teacher, it provides an environment for the development of a course framework, and the integration of teaching materials from a variety of sources.  Futher advantages of the eRoadmap from the perspectives of both students and teachers are discussed, and future directions for development, evaluation and research are outlined.

Innovative science education assessment : linking theory with practice

This paper presents an assessment approach which demonstrates the characteristics of excellent assessment. In a third year Science Education unit in an undergraduate degree in teacher education, assessment is seen as an integral part of the learning process. Learning outcomes are improved for the students and they appreciate the validity of the assessment. Assessment is an important aspect of any unit in higher education but should be seen, not as an end in itself, but rather as a means for educational improvement. Using the assessment task as an illustration, this paper will discuss the theoretical framework of assessment. It will describe how the unit, delivered in a school-based mode, provides opportunity for students to link their theoretical understandings with practical applications, drawing together the academic debates with the first-hand experiences. It will illustrate how the assessment task itself embeds the principles of constructivism and conceptual change models in science education. Finally, the paper will highlight the benefits of this assessment approach with particular reference to the student learning.

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.

Critical incident analyses : a practice learning tool for students and practitioners

The development of critical skills in social work students and practitioners has been a major focus of social work education and training in recent years. Critical incident analysis has developed as a tool to aid critical reflection in practice, in health and social work. This paper provides an overview of the use of the tool in these fields. It then reports on a demonstration project which sought to examine how critical incident analysis might be used as a form of assessment and as a supervisory tool by social work students and practice teachers. An evaluation of the project is provided. Completion of critical incident analyses using the framework was found to provide a structured approach to critical reflection. It assisted the integration of theory and practice and the examination of value issues. Students and practice teachers identify its use in supervision and its potential as an assessment tool. The paper concludes with a discussion on the potential uses of critical incident analyses, with particular attention given to its use to develop anti-oppressive practice.

Teacher researchers - sustaining professional learning

In this paper we argue for an approach to professional development which supports teachers to engage in sustained intellectual inquiry and to investigate the conditions in their classrooms that might make a difference for students at risk of not succeeding at school. We focus on the work of one primary school teacher involved in the research project Teachers investigate unequal outcomes in literacy: Cross generational perspectives and explore the effects that redesigning her literacy curriculum had on her professional identity and the literacy outcomes for one of the children in her class. We suggest that the principles of building theory and practice, positioning teachers as agentive, and making a space for teachers to bring new – and renewed – professional knowledge to their work are principles of practice that energise and sustain teachers and their day-to-day classroom work. Such principles deserve attention, particularly at a time when teacher quality and professional standards are in the minds of policy makers.

A primary numeracy : a mapping review and analysis of Australian research in numeracy learning at the primary school level : report

The outcome from this project produces a database of over 185 projects and 726 publications relating to numeracy research to systematically ‘mapped’ Australian research on primary school numeracy over the last decade. The database incorporates research summaries and findings that are easily accessible to teachers and teacher educators, and act as a valuable tool for determining further research directions. The project report examines the available research and organises the discussion of the research findings under a set of themes and sub-themes.

Some summarised examples from the report reveals that:

* Effective teachers of numeracy:
- have high expectations of their students;
- focus on children’s mathematical learning, rather than on providing pleasant classroom experiences;
- provide a challenging curriculum;
- use higher-order questioning;
- make connections both within mathematics and between mathematics in different contexts; and
- use highly interactive teaching involvement with students in class discussion.

* Effective professional development programmes:
- provide teachers with the time and appropriate resources to enable them to reflect on their teaching;
- provide continuing support and encouragement while teachers explore possibilities and trial new strategies in their classrooms;
- involve teachers in school-based and wider networks;
- are of sufficient duration to allow significant changes to habitual beliefs and practices; and
- create opportunities for the exploration of theory-practice relationships.

Constructivism in environmental education beyond conceptual change theory

Constructivism, as a set of theories about how learners learn, has been an important discourse in the educational research literature for a number of years. Interestingly, it has been far more visible in science education research than in environmental education research. This article considers conceptual change theory within constructivism as a contested concept, outlines differing expressions of constructivism in science education and environmental education, and argues for approaches to environmental education that adopt socially constructivist perspectives with respect to the character of the subject matter content as well as to learners' apprehension of such content. In considering implications for research, this perspective is juxtaposed with a recent United States Education Act, which prescribes a far more objectivist approach to educational research and which serves as a reminder that research itself is a powerful factor in shaping how we construct the nature of subject matter, learning and the implications of these for teaching practice.

Research supports quality learning

This article reports on research currently being conducted at the Faculty of Education, Deakin University, into the factors that contribute to quality learning. It describes a shift in research focus from an emphasis on teachers and teaching to an emphasis on learners and learning, as well as to exploring how learning occurs within a social context.

Using activity theory in researching young children's use of calculators

Constructivist and socio-cultural perspectives in mathematics education highlight the crucial role that activity plays in mathematical development and learning. Activity theory provides a socio-cultural lens to help analyse human behaviour, including that which occurs in classrooms. It provides a framework for co-ordinating constructivist and socio-cultural perspectives in mathematics learning. In this paper, we adopt Cole and Engeström's (1991) model of activity theory to examine the mediation offered by the calculator as a tool for creating and supporting learning processes of young children in the social environment of their classroom. By adopting this framework, data on young children's learning outcomes in number, when given free access to calculators, can be examined not only in terms of the mediating role of the calculator, but also within the broader context of the classroom community, the teachers' beliefs and intentions, and the classroom norms and the division of labour. Use of this model in a post hoc situation suggests that activity theory can play a significant role in the planning of future classroom research.

Plagiarism – can preventative measures and a commitment to the value of learning by academics and students reduce plagiarism in classrooms?

Plagiarism is an interruptive act in the teaching and learning value chain. This paper analyses the impact of both plagiarism and effective assessment in the learning value chain. Effective assessment is the positive outcome. Plagiarism negates or breaks the chain. Anecdotal evidence suggests the incidences of plagiarism are increasing in faculties across the Queensland University of Technology (QUT), and where every subject/unit outline includes a statement and warning to students of the penalties of this activity, deterrence tools do not overcome the harmful impact of plagiarism on the teacher/student learning relationship. A working party established in 2000 in the Faculty of Business at QUT, examined the literature, university policies, teaching and learning practices, and examples of plagiarism and penalties in order to identify the wider learning and assessment issues surrounding plagiarism and options for action and policy. A three-semester study of acts of plagiarism and wide consultation with staff presented the working party with an opportunity to develop a set of preventative measures, and also exposed the legal, cultural and accountability issues of diverse attitudes and values.

The paper presents the findings and recommendations from the investigation, and also proposes an interpretation of marketing theory of the impact of plagiarism on the teaching and learning value chain.

Evolutionary approach to revising modernization theory : an introduction to the credible polity

The future global distribution of the political regimes of countries, just like that of their economic incomes, displays a surprising tendency for polarization into only two clubs of convergence at the extrema. This, in itself, is a persuasive reason to analyze afresh the logical validity of an endogenous theory for political and economic development inherent in modernization theory. I suggest how adopting a simple evolutionary game theoretic view on the subject allows an explanation for these parallel clubs of convergence in political regimes and economic income within the framework of existing research in democratization theory. I also suggest how instrumental action can be methodically introduced into such a setup using learning strategies adopted by political actors. These strategies, based on the first principles of political competition, are motivated by introducing the theoretical concept of a Credible Polity.
