ItemA program theory of the Bushfire blitz program( 2001)Program theory has become increasingly prominent in evaluation in recent years. The thesis explores the notion of program theory by examining the writings of several evaluators and attempts to distill the key elements of a comprehensive model of program theory from a realist perspective. This model of program theory is used as a basis to develop a program theory of the Bushfire Blitz program, a community-based education and advice program intended to increase residents' preparedness to deal with the bushfire risk. The thesis reviews literature in the fields of risk perception, risk communication and the adoption of precautionary behaviours. Several evaluation studies of Bushfire Blitz are also considered. The findings from the literature review and the review of evaluation studies are synthesised to develop a program theory of Bushfire Blitz. The thesis examines how individuals and communities respond to risk, the nature of preparedness for the bushfire risk and decision making processes in response to risk. Examination of these aspects is essential in order to understand how the Bushfire Blitz program can bring about change in both individual and community response to the bushfire risk. The program theory developed in the thesis highlights the importance of several crucial aspects of realist approaches to evaluation such as the role of psychosocial mechanisms, the nature of program effects at both micro and macro levels, and the effects of contextual complexity on the program. The program theory provides guidance for program improvement and the basis for on-going evaluation of Bushfire Blitz and similar programs to address the risk from natural hazards.

ItemIntegrating formative and summative assessments: finding time-efficient ways to support student learning and teacher reporting( 2009)This study has set out to find ways in which the formative and summative goals of assessment could be achieved using the same instruments. The motivation for this integration of goals was to achieve time efficiencies, so that teachers could implement formative assessment in a way that would have minimal impact on their time. The researcher developed five short questionnaires, referred to in this thesis as recap sheets. These consisted of questions on the Measurement topic and were used by the researcher as well as another teacher at the same school with their respective Year Seven classes. A third teacher participated in the study and did not use the recap sheets. At the end of the teaching sequence, all three teachers predicted the marks that their students would achieve on a summative test. The researcher then interviewed the other two teachers to ascertain the sources of their predictions. The quantitative analysis of the teachers' predictions has shown that they were capable of predicting the performance of the majority of their students within an accuracy margin of 10%. Furthermore, when used to allocate grades, the predictions of the most experienced teacher in the study discriminated between the students more sensitively than did the marks achieved on the summative test. Another finding of the study was that all participating teachers were most accurate in predicting the performance of the students who achieved the lowest 25% of the test marks. Furthermore, the recap sheets were found to be effective in supporting student learning. In summary, the findings of this study suggest that neither continuous formative assessment instruments nor an end of unit summative test are, by themselves, sufficient to generate an accurate report of a student's performance. The use of recap sheets and teacher predictions as described above was shown to be a minimally demanding way of increasing the accuracy of summative assessments for grading purposes, while providing great benefits to student learning.
