Accreditation for off-campus engineering programmes has proven to be problematic. In Australia, off-campus programmes are compelled to contain mandatory residential sessions so that offcampus students can have an `on-campus experience'. This paper explores the nature of modern oncampus undergraduate engineering study, and finds that it now typically involves at least part-time employment and has more in common with off-campus study than the on-campus experience enjoyed by most of the current institutional (education and professional) administrators when they completed their undergraduate studies. Rather than ignore student term-time work, engineering programmes should use it to enhance the development of desirable graduate attributes.

Evidence from epidemiologic studies that central obesity precedes future metabolic change and does not occur concurrently with the appearance of the blood pressure, glucose, and lipid abnormalities that characterize the metabolic syndrome (MetS) has been lacking. Longitudinal surveys were conducted in Mauritius in 1987, 1992, and 1998, and in Australia in 2000 and 2005 (AusDiab). This analysis included men and women (aged 25 years) in three cohorts: AusDiab 2000–2005 (n = 5,039), Mauritius 1987–1992 (n = 2,849), and Mauritius 1987–1998 (n = 1,999). MetS components included waist circumference, systolic blood pressure, fasting and 2-h postload plasma glucose, high-density lipoprotein (HDL) cholesterol, triglycerides, and homeostasis model assessment of insulin sensitivity (HOMA-S) (representing insulin sensitivity). Linear regression was used to determine which baseline components predicted deterioration in other MetS components over 5 years in AusDiab and 5 and 11 years in Mauritius, adjusted for age, sex, and ethnic group. Baseline waist circumference predicted deterioration (P < 0.01) in four of the other six MetS variables tested in AusDiab, five of six in Mauritius 1987–1992, and four of six in Mauritius 1987–1998. In contrast, an increase in waist circumference between baseline and follow-up was only predicted by insulin sensitivity (HOMA-S) at baseline, and only in one of the three cohorts. These results suggest that central obesity plays a central role in the development of the MetS and appears to precede the appearance of the other MetS components.

The thesis investigates the role a calculator can play in the developing number knowledge of three girls and three boys as part of their mathematics program, during their first two years at primary school. Random sampling was used initially to select six girls and six boys from the twenty-four children entering a 1993 prep class. These twelve children were interviewed on entrance to school and based on the performance of the twelve children on the initial interview, a girl and a boy were chosen from the higher, middle and lower achievers to take part in the full study. The class teachers involved were previously participants in the ‘Calculators in Primary Mathematics’ research program and were committed to the use of calculators in their mathematics program. A case study approach using qualitative methods within the activity theory framework is used to collect relevant data and information, an analysis of five interviews with each child and observations of the children in forty-one classroom lessons provides comprehensive data on the children's developing number knowledge during the two years. The analysis questionnaires establishes each teacher's perceptions of the children's number learning at the beginning and end of each year, compares teacher expectations with children's actual performance for the year and compares curriculum expectations with children's actual performance. A teacher interview established reasons for changes in teaching style; teacher expectations; children's number learning; and was used to confirm my research findings. An activity theory framework provides an appropriate means of co-coordinating perspectives within this research to enable a description of the child's number learning within a social environment. This framework allows for highlighting the mediation offered by the calculator supporting the children's number learning in the classroom. Levels of children's developing number knowledge reached when working with a calculator and as a result of calculator use are mapped against the levels recommended in ‘Mathematics in the National Curriculum’ (National Curriculum Council, December 1988), and the Curriculum and Standards Framework: Mathematics (Board of Studies 2000). Findings from this comparison illustrate that the six children's performance in number was enhanced when using a calculator and indicate that on-going development and understanding of number concepts occurred at levels of performance at least two years in advance of curriculum recommendations for the first two years of school.

Drawing as a means of recording is a very common practice in junior primary science lessons. This is largely due to the availability of necessary materials. Also, most youg children have some degree of drawing skill and enjoy drawing activities. Since 1956 the science curriculum to be implemented in primary classrooms in Victoria has changed from one that was based largely on nature study (biological) to one that includes physical and technological aspects. Further, there have been changes in the teaching methodologies advocated for use in science lessons. A modified Interactive Teaching Approach was used for the studies. Drawing was the main means by which the children recorded information. The topic of 'shells' was used to enable collection of data about the children's enjoyment of the activity and satisfaction with their achievement. This study was replicated using the topic 'rocks'; again data were collected concerning satisfaction and enjoyment. During a series of lessons on 'snails' data were collected concerning the achievement of 'process' and 'objective' purposes that teachers might have in mind when setting a drawing activity. In addition to providing data about purposes the study stimulated some questions regarding the techniques the children had used in their drawings. Accordingly, data concerning the use of graphic techniques by the children were collected during a series of lessons on 'oils'. The data collected and analysed in the various studies highlighted the value of drawing in junior primary school science lessons. It also validated strategies developed by the author and designed to help teachers and children use drawing effectively in science activities.

My dissertation asserts that the discourses which at the present time construct the world of work for teachers in adult TESOL, are no longer adequate to represent the field in these new and rapidly changing times. For the last forty years the discourses that have constructed the field present a totalising, gender free, liberal humanist view of TESOL, rendering women's experience invisible, no longer speaking to or for women teachers who make up more than ninety percent of the teachers in Victorian adult TESOL programs (Cope & Kalantzis 1993, Brodkey 1991, Fine 1992, Peirce 1995). I begin by exploring the work of women teachers in adult TESOL, focusing on women teaching in the fast growing de-institutionalised settings of adult TESOL programs, which remain marginalised from the central programs in terms of administrative policy and practice. I report the findings of a series of projects undertaken by the teachers and the researcher by which new insights and understandings of teachers beliefs about their work and the changes which are currently reconstructing the field of adult language and literacy education in Australia, have been gained. I questions the discourses of applied linguistics which have for the past forty years constructed the field of adult TESOL in Australia and suggests that these lack a social theory (Candlin 1989). From the research findings I questions the possibility of continuing to work in the ways of the past, in the current climate of reconstruction of the field, rapid policy change and continued erosion of resources. I suggest that the previously loose system which held this field of work together, the ways of working, the understandings of practice, have in the light of these new times, been stretched to the limit and are in real danger of collapse. For the women working in TESOL this continued incursion of the systems into their work and the changes that have taken place, the denial of their ways of working, their local knowledge and gendered experiences, can be read against Habermas' concept of the colonisation of the lifeworld of language teaching (Habermas 1987).

Proponents of socially and culturally oriented mathematics education have argued that teaching approaches which value and connect with the learner's prior knowledge and everyday experience are more likely to promote active, meaningful, relevant and liberatory learning than approaches which rely on transmission and abstract presentation of mathematical content. In Malawi, proposals to reform the outdated secondary mathematics curriculum have been made with the aim of aligning mathematics instruction with the social and political changes in the current Malawian society. Using a case study approach, this study investigated the extent to which everyday experiences could be used as a vehicle for changing the learning and teaching of secondary mathematics in Malawi. The study was collaborative, taking place over a period of five months in severely overcrowded and poorly resourced classes in two schools. It involved three mathematics teachers in a cycle of planning and teaching mathematics lessons based on the use of everyday experiences, and observation of and reflection on these lessons, in order to document the effects of using everyday experiences on student learning and teachers' teaching practices. The data was collected through student questionnaires; classroom observations and fieldnotes; interviews and reflective meetings with teachers; and informal meetings with key education officials in Malawi. Mathematics examination results from students involved in this study and a corresponding group from the previous year were collected. A reflective and critical approach was adopted in the interpretation and discussion of the data. Teachers' participation in this study resulted in heightened awareness of their teaching roles and the value of linking school mathematics with everyday experience. The study also shows that students found mathematics interesting and important to learn despite their lack of success in it. In addition, the study documented a number of constraints to change in mathematics instruction such as teachers' focus on mathematics content and examination requirements, and students' resistance to inquiry learning. It also recorded possibilities and barriers to collaboration both between teachers and researchers, and teachers themselves. The findings of this study are timely since they could serve to inform the reform of the Malawian secondary mathematics curriculum currently being undertaken, which began without a critical examination of the classroom conditions necessary to accommodate a socio-politically relevant mathematics education.

This study addresses questions of gender and genre in early writing by drawing on systemic linguistic theory, It is a longitudinal case study that compares the writing development of two children, a boy and a girl/ who learned to write in classrooms that adopted an approach to writing known in Australia as 'process writing1, The children's written texts were analysed using the systemic functional grammar as developed by MAK, Hallidey and the models of genre and register as proposed by J,R, Martin. The children were followed for the first two and a half years of their schooling, from the first day of kindergarten to the middle of grade two. They were observed weekly during the daily ‘writing time’ and all texts were collected. Although the children were ostensibly 'free’ to determine both the writing topics and text types they produced, systemic analysis revealed that: 1) the majority of texts written were of one genre, the Observation genre, in which the children reconstructed their personal experience with family and friends and offered an evaluation of it. 2) a significant pattern of gender differences occurred within this genre, such that the boy reconstructed experience in terms of the male cultural stereotype of being an active participant in the world, while the girl reconstructed experience in terms of the female stereotype of being a more passive observer of experience. It is the strength of systemic linguistic analysis that it revealed how the choices the children made in language were constrained by a number of social and cultural contexts, including: a) the teacher's theoretical orientation to literacy; b) the models of spoken and written language available to the children; and c) the ideology of gender in the culture. In particular, the analysis made visible how children appropriate the meanings of their culture and socialise themselves into gender roles by constructing the ideology of gender in their writing. The study contributes to an understanding of genres by offering a revised description of the Observation genre, which derives from the Observation Comment genre originally identified by Martin and Rothery (1981). It also raises a number of implications for teacher training and classroom practice, including the need for: 1) increased teacher consciousness about gender and genre, especially an understanding that choices in language are socially constructed 2) a critical reassessment of the notion of 'free topic choice’ promoted by 'process writing' pedagogy, a practice which may limit choice and tacitly support the gender status quo.

This study provides empirical evidence on the nature and extent of risks faced by Small to Medium-Sized Knowledge Intensive Firms (SMKIFs) and the risk management approaches adopted by them. The study also assesses the effects of selected organisational factors such as industry, entity size and risk governance leadership on the commitment by SMKIFs to using an Enterprise Risk Management (ERM) approach. Data was obtained through a questionnaire survey of SMKIFs in the state of Victoria, Australia which were either in the bio-technology (bio-tech) or the accounting and legal (business services) industry sectors. Based on a total of 104 (13%) useable responses from senior managers in charge of risk management, some of the key findings include the identification of the top three risks faced by SMKIFs being (i) potential damage to firm’s reputation, (ii) inability to recruit and retain workers who have appropriate skills and expertise, and (iii) increase in costs. Interestingly, while 51% of the respondents described their firms as being willing to or keen to take risks, 38% saw their firms as being either preferring not to take risks or refuse to take risks, with the remainder of the firms (11%) viewed as neutral. The data also indicates that more than half of the respondent firms (54%) had established either a complete or a partial ERM system. Further, data analysis based on a binary logit regression model indicates bio-techs, firm size and directors’ support of risk management as key predictors of ERM implementation in SMKIFs.

The newly developed Curriculum Standards Framework lacked supporting school documentation to implement an effective program in Science and SOSE. The task was to create it, together with the knowledge and understandings that were required to apply it. The thesis demonstrates the difficulties faced in actively pursuing curriculum change in a primary school.
