Student-generated submicro diagrams : a useful tool for teaching and learning chemical equations and stoichiometry

This paper reports on a pedagogical approach to the teaching of chemical equations introduced to first year university students with little previous chemical knowledge. During the instruction period students had to interpret and construct diagrams of reactions at the submicro level, and relate them to chemical equations at the symbolic level with the aim of improving their conceptual understanding of chemical equations and stoichiometry. Students received instruction in symbol conventions, practice through graded tutorial tasks, and feedback on their efforts over the semester. Analysis of the student responses to formative test and summative exam items over consecutive years indicates that there was a consistent improvement in the abilities of the various cohorts to answer stoichiometry questions correctly. The responses provide evidence for diagrams of the submicro level being used as tools for reasoning in solving chemical problems, to recognise misconceptions of chemical formulae and to recognise the value of using various multiple representations of chemical reactions connecting the submicro and symbolic levels of representation. The student-generated submicro diagrams serve as a visualisation tool for teaching and learning abstract concepts in solving stoichiometric problems. We argue that the use of diagrams of the submicro level provides a more complete picture of the reaction, rather than a net summary of a chemical equation, leading to a deeper conceptual understanding.

Teaching and learning about force with a representational focus : pedagogy and teacher change

A large body of research in the conceptual change tradition has shown the difficulty of learning fundamental science concepts, yet conceptual change schemes have failed to convincingly demonstrate improvements in supporting significant student learning. Recent work in cognitive science has challenged this purely conceptual view of learning, emphasising the role of language, and the importance of personal and contextual aspects of understanding science. The research described in this paper is designed around the notion that learning involves the recognition and development of students’ representational resources. In particular, we argue that conceptual difficulties with the concept of force are fundamentally representational in nature. This paper describes a classroom sequence in force that focuses on representations and their negotiation, and reports on the effectiveness of this perspective in guiding teaching, and in providing insight into student learning. Classroom sequences involving three teachers were videotaped using a combined focus on the teacher and groups of students. Video analysis software was used to capture the variety of representations used, and sequences of representational negotiation. Stimulated recall interviews were conducted with teachers and students. The paper reports on the nature of the pedagogies developed as part of this representational focus, its effectiveness in supporting student learning, and on the pedagogical and epistemological challenges negotiated by teachers in implementing this approach.

Australian higher education institutions transforming the future of teaching and learning through 3D virtual worlds

What are educators‟ motivations for using virtual worlds with their students? Are they using them to support the teaching of professions and if this is the case, do they introduce virtual worlds into the curriculum to develop and/or expand students' professional learning networks? Are they using virtual worlds to transform their teaching and learning? In  recognition of the exciting opportunities that virtual worlds present for higher education, the DEHub Virtual Worlds Working Group was formed. It is made up of Australian university academics who are investigating the role that virtual worlds will play in the future of education and actively implementing the technology within their own teaching practice and  curricula. This paper presents a typology for teaching and learning in 3D virtual worlds and applies the typology to a series of case studies based on the ways in which academics and their institutions are exploiting the power of virtual worlds for diverse purposes ranging from business scenarios and virtual excursions to role-play, experimentation and language development. The case studies offer insight into the ways in which institutions are transforming their teaching for an unknown future through innovative teaching and learning in virtual worlds. The paper demonstrates how virtual worlds enable low cost alternatives to existing pedagogies as well as creating opportunities for rich, immersive and authentic activities that would otherwise not be feasible or maybe not even be possible. Through the use of virtual worlds, teaching and learning can be transformed to cater for an unknown future.

Changing technologies / renewing pedagogies : implications for university teaching and learning

This chapter describes a project that researched the use of Web Enhanced Learning (WEL) with postgraduate students from rural and remote communities who were studying through two Australian universities. We examine, in detail, the experiences of a university teacher using WEL in an off-campus course for the first time. As with many academic teachers, she was willing to use new technologies and integrate these into her teaching but required time, technical support and professional development to achieve this. Using a design-based rnethodological approach, the experiences and frustrations in introducing WEL are described from the teacher's perspective trough her progressive reflections at stages throughout the course. The findings and their implications for university policy and leadership are detailed with conclusions about how teachers and students are best supported in their engagernent with WEL.

Complexity and learning behaviours in product innovation

Successful product innovation and the ability of companies to continuously improve their innovation processes are rapidly becoming essential requirements for competitive advantage and long-term growth in both manufacturing and service industries. It is now recognized that companies must develop innovation capabilities across all stages of the product development, manufacture, and distribution cycle. These Continuous Product Innovation (CPI) capabilities are closely associated with a company’s knowledge management systems and processes. Companies must develop mechanisms to continuously improve these capabilities over time.  Using results of an international survey on CPI practices, sets of companies are identified by similarities in specific contingencies related to their complexity of product, process, technological, and customer interface. Differences between the learning behaviors found present in the company groups and in the levers used to develop and support these behaviors are identified and discussed. This paper also discusses appropriate mechanisms for firms with similar complexities, and some approaches they can use to improve their organizational learning and product innovation.

Reflecting on contemporary accounting : teaching and learning social and critical perspectives

This paper provides a case description and analysis of an effort to enact accounting education change. The study reports on an attempt to renew the social and ethical worth of accounting education and practice in the post-Enron context of increased interest in how accounting may contribute to social responsibility and sustainability. The paper considers the organisation, aims, and content of a newly-developed unit on social and critical perspectives on accounting, and key elements of the pedagogy utilised. These include team teaching, the employment of research literature rather than a prescribed textbook, an expanded conception of accounting and accounting “knowledge”, the adoption of educational goals that encompass preparing students for economic and social life and for democratic participation, and a view that sees ethics, the environment, and society as central to accounting. It is concluded that accounting educational change must encompass the content and practice of classroom activity, but it also requires change to the self-consciousness of all actors involved. Explicit inclusion of the social, critical, environmental and ethical dimensions of accounting in our teaching and learning programs provides an avenue for academics to individually and collectively make a meaningful contribution.

Changing perspectives : teaching and learning centres’ strategic contributions to academic development in Australian higher education

This article reports on a study of Australian teaching and learning centres to identify factors that contribute to their effective strategic leadership. These centres remain in a state of flux, with seemingly endless reconfiguration. The drivers for such change appear to lie in decision makers’ search for their centres to add more strategic value to organisational teaching, learning and the student experience. Through a synthesis of findings based on interviews, a survey of directors of centres and focus groups, the article identifies paradigmatic shifts in the ways centres see themselves, relate to their organisations and respond to external environmental forces. From an understanding of paradigm shifts, strategic contributions to academic development in the sector are framed organisationally through key points of leverage. Points of leverage are manageable actions that can be taken to maximise overall institutional impact and effectiveness.

Distributed cognition and IT support for knowledge work in breakdowns : match or mismatch?

Knowledge is instrumental in organisational problem solving and is embedded in organisational processes and routines. We explore the application of IT in breakdowns (forms of interruptions from normal organisational work routines) and illustrate the application of distributed cognition theory (DCT) as a useful lens to explain the exchange of knowledge in breakdowns. DCT also allows for a rich analysis of the role that information technology (IT) can play to foster knowledge exchange in breakdown situations. We use two cases to illustrate that DCT is useful in identifying the matches and mismatches in IT support for exchanging knowledge in breakdowns.

Strategic leadership of teaching and learning centres : from reality to ideal

This paper reports on the third phase of a study of Australian Teaching and Learning Centres to identify factors that contribute to the effective strategic leadership of Centres. Focus groups at 10 Australian universities included 66 respondents, providing a diverse range of perspectives, from students to members of the university executive. Analysis of participant contributions extended findings from prior project phases and the wider literature. They also contributed to the final construction of the strategic leadership Teaching and Learning Centre maturity framework presented here. Centres remain in a state of flux, enduring regular reconfiguration. For most Centres, their level of interaction with students is low and increased engagement with students would be of benefit. Perceptions of Centres vary widely, reinforcing the importance of a strategic partnership between the University’s Senior Executive, the Centre and faculties as a prerequisite for implementing identified high-impact strategies for improvement in teaching and learning.
