This thesis is a study of the patterns of female enrolment in Information Technology in a co-educational private school in the Eastern suburbs of Melbourne. What makes this school so interesting is that few girls elect to take any of the Information Technology subjects in Years 11 and 12. This study set out to explore the reasons for these striking statistics in the light of the research which has already been undertaken as well as indicating areas for future research. The first chapter provides a basic introduction to the study outlining the context in which the research took place. Chapter Two sums up the theoretical writings and research findings conducted by others in the field of females not studying Information Technology. What emerges is that the literature is categorised into seven factors and each factor is discussed in turn. Chapter Three outlines the method of evaluation of the history of the introduction of Computer Science at Wrixon Grammar. The method of evaluation was by case study. The case study which is Chapter Four reconstructs the history and development of Computer Science at Wrixon Grammar. Chapter Five analyses the case study in Chapter Four and compares it to the current literature in Chapter Two. The seven factors which became apparent in Chapter Two form the basis for the analysis. The findings suggest that rather than identifying only sociological factors in the reasons why females do not elect to study Information Technology, more research needs to be conducted on school based/ institutional factors which have an impact on Information Technology enrolments. In the final chapter, the conclusions and recommendations for further research and practice are presented.
