ItemMicroWorlds programming, mathematical problem solving and teaching for transfer : a year long classroom study( 2000)This thesis is based on research conducted to investigate the effects of computer programming on cognitive and affective outcomes in two upper primary classes. The subjects of the research comprised two classes of eleven to twelve year old students at the same school in Melbourne, Victoria. The aims of the research were to establish whether a particular type of methodological intervention, which reinforced strategies developed in a programming context, could improve the likelihood that problem-solving strategies acquired through programming would be transferred to mathematical problem-solving. In addition, the research set out to investigate whether programming affected individuals with differing personality traits in different ways. Students worked over a twelve-month period with the programming software MicroWorlds. In the first term they learned basic semantics and syntax of the programming language and thereafter completed five tasks that were research assignments from a range of key learning areas. These tasks were called Lap-T tasks and as part of the overall curriculum were completed and presented for evaluation. Pre and post-tests in maths problem solving which sought evidence of ability to obtain correct answers, identify appropriate strategies and articulate strategies used, were administered at the beginning and end of the year. In addition, students completed a questionnaire at the beginning, middle and end of the year to establish attitude change to aspects of learning with computers and learning through programming. Other data was obtained through the Rosenberg Self Esteem Test and the Eysenck Personality Inventory. Students kept journals in which they reflected on their programming experience. A series of class lessons for highlighting strategies developed in programming, called strategy training was directed towards one group only, the Strategy Training Group or STG for a total of 18 hours. The other group, the Independent Learning Group, was not assisted to make connections beyond those automatically acquired while programming. The findings of the research were an affirmation for the value of the strategy training for improving the likelihood that strategies acquired during programming would transfer to other problem-solving contexts. In addition, there was confirmation that programming is a valuable addition to an upper primary curriculum, contributing to students' perceptions of control of their own learning and providing challenge and satisfaction while developing transferable problem-solving skills. The research indicates that strategic use of programming in the primary school curriculum can be utilised in the development of improved use of mathematical problem-solving strategies.

ItemChildbirth and childbirth education: a study of critical factors in psychological adaptation among primigravidae( 1978)Factors which facilitate or retard psychological adaptation in the stressful period of childbearing have been the focus of a continuing theoretical controversy, begun by Grantly Dick-Read (1944) and Helene Deutsch (1945). Their disagreement centred on the effectiveness of ante-natal education in reducing maternal anxiety through the provision of information about the reproductive process, as well as the advisability of attempting to reduce anxiety. For Dick-Read and subsequent childbirth educators, anxiety in pregnancy was predictive of physical and psychological maladjustment. Consequently, the elimination of anxiety and the production of self-esteem have been fundamental aims for ante-natal education programs. Deutsch argued that Dick-Read had ignored important primal anxieties which neither could nor should be removed through ante-natal education, because of the crucial role they played in preparing women for the stresses of labour. The theoretical disagreement between these two writers provided a context within which subsequent empirical research findings were evaluated, and informed the experimental hypotheses of the present study. Ninety primigravidae, of whom 45 attended ante-natal education classes and 45 did not, took part in the investigation carried out between May 1976 and May 1977. Subjects were tested late in pregnancy, during labour and early in the post partum, on a variety of questionnaire measures concerning attitudes towards various aspects of reproduction, state and trait anxiety, and attitudes towards self and significant others. Subjects were also interviewed individually about their labour experience in the early post partum. During labour, subjects were randomly assigned to a no treatment group, a group which listened to popular music, and one which listened to a tape giving information on coping with labour. Only state anxiety level was ascertained during labour. Contrary to prediction, women who had attended ante-natal education classes did not have significantly lower levels of state or trait anxiety on any of the testing occasions than did untrained women. Similarly, there was no significant difference in state anxiety depending on an interaction between group membership and treatment level during labour. There were no significant differences favouring trained women over untrained women on any of the obstetrical indices of labour. Of the significant results which were obtained, most favoured untrained women. Thus, in the post partum, untrained women perceived greater congruence between current self-concepts and those relating to 'doctors', 'pleasant and good things', 'nurses', 'childbirth' and 'the ideal mother', contrary to prediction. There were also highly significant changes in state and trait anxiety over the testing occasions regardless of group membership. It was concluded that the significant changes in state and trait anxiety supported the notion of childbearing as a crisis which ante-natal education did little to ameliorate. The possibility that anxiety played a useful role in preparing women for labour was considered. Ways of improving antenatal education, based on the findings of the current study and those from the research literature on coping with stress, were discussed.
