Improving teaching in tertiary education : institutional and individual influences

Technology education, science and science education : exploring the relationship

In this paper the nature of technology education in relation to science and science education is explored. Ways forward are indicated for both technology and science in the curriculum so that the two areas can be mutually supportive. In the 1990s, when curriculum writers were attempting to provide technology a unique place in the curriculum, they tended to downplay the relationship between technology and science. One reason for this tendency derives from a perception that science is an academic and elitist discipline and technology is well served by emphasizing the distance between the two. The other reason is perhaps political, that science, by virtue of its status in the community, and the status of its special type of knowledge, would be in a position, if allowed, to subsume the new subject. There are philosophical and historical precedents that justify such a concern. In tracing the historical relationships between science and technology, in professional practice, in philosophical positioning, and in school curriculum, we inevitably need to deal with the politics of school subjects.

The position taken in this paper is that science and technology are different, both in their epistemological foundations, and in the nature of the professional communities and the concerns of individual practitioners within the two areas. In clarifying these differences the essential nature of technology and of science are illuminated. The paper also explores ways in which the two areas can benefit from each other’s existence in the curriculum, and ways of approaching teaching that both clarifies the special nature of each type of knowledge, and allows them to be mutually supportive. This may necessitate a reconstruction of the nature of school science.

Development and evaluation of a glass-box interpreter for teaching novice programmers

This study evaluates the efficacy of a low-level program visualisation tool as a learning aid for novice programmers and develops and evaluates features which might further enhance the benefit of a low-level program visualisation tool (called Bradman). Bradman is an interpreter which makes visible aspects of the programming process which are normally hidden from the user.

PTSD symptomatology in children and adolescents : treatment development and evaluation

This thesis developed, implemented and evaluated a cognitive-behavioural group treatment programme for children and adolescents experiencing symptoms of PTSD (Post-traumatic stress disorder). Results of the study indicate that symptoms of sleep disturbance and flashbacks, reduced markedly in the participants, providing a useful tool in reducing synptoms experiences by individuals exposed to trauma. The Professional portfolio presents four case studies that demonstrate the clinical application of the affect of chronic illness on the psychological adjustment of the sufferer and their families.

The design and evaluation of two types of chemical sensor

During the course of this investigation it was discovered that functionalised Ruthenium tris(bipyridyl) complexes exhibit different chemical, spectroscopic and electrochemical properties to those of the parent compound. Furthermore, it was possible to develop 1,8-naphthalimide-based compounds that furnished strong 1:1 host:guest complexes with larger anions such as hydrogen pyrophosphate. This dissertation presents in investigation into the systhesis and analytical evaluation of two types of chemical sensors: chemiluminescent and fluorescent.

Existence of externalities from investment in higher education research and development

Research undertaken for this thesis supports the underlying claim that education does generate externalities. By examining the impact of higher education R&D on Australian state production, the results suggest that both pure and applied R&D have a statistically significant impact on Australia's regional economic performance.

Design, fabrication and evaluation of universal polymerase chain reaction devices

Novel and low cost PCR devices were developed to perform rapid polymerase chain reaction based diagnostics for infectious diseases. The main advantages of using these devices are that it can perform multi sample and also multiplexing of DNA samples woth low sample volume compared to the conventional PCR devices.
