- Description: Population dynamics is a South African secondary school biology syllabus topic which deals specifically with ecology or concepts within the realm of ecology. It is currently taught in a way which largely emphasises the teaching and learning of facts and concepts, often out of any context to which students can relate. While it is important to convey scientific concepts, it is just as important to address social and political issues regarding overpopulation and the environment. This research involved the administration of a questionnaire to Std 10 biology teachers in the Department of Education and Training (DET), which sought to obtain information about various aspects of teachers' teaching of population dynamics. These included their feelings toward the teaching of the specific sections of the population dynamics syllabus, and their knowledge and views of environmental issues and human population expansion. The findings of the research suggest that population dynamics is an important topic for students to learn about. The traditional teacher-centred approach to teaching is used by the teachers in the research sample. The sections considered by the teachers to be most important for learning were also considered the most interesting and the easiest to teach. The majority of the teachers in the research sample recognised that human population growth is a global and local problem and that South Africa cannot sustain its present population growth. The teachers in the sample show a diversity of opinions about sustainable development, and have a limited understanding of the links between population, poverty and consumption. Important information gained from the research will be significant in the development of a teaching and learning module on population dynamics that reflects the aims and purpose of environmental education.

Equality, resources and primary goods: Ronald Dworkin and John Rawls on the currency of egalitarianism

- Description: In this thesis I compare the work of Ronald Dworkin and John Rawls within the context of the 'equality of what?' debate. I argue that the Rawlsian paradigm offers a much more flexible defence of a resourcist approach to egalitarianism than Dworkin's theoI)' of' equality of resources'. I argue that Dworkin's fundamental distinction between persons and circumstances is flawed because it involves commitment to a view of the person which belongs in the realm of' comprehensive moral doctrines', rather than in the realm of a political theory of justice. I also argue that an alternative distinction between choice and luck, expressed in the 'luck-neutralising aim' of egalitarianism, is inappropriate since it too involves transgressing political constraints on theories of justice. Rawls's utilisation of primary goods in his theory of justice is supported by considerations derived from the work of Thomas Scanlon. The schematic picture of relative urgency which Scanlon advances provides the rationale for the use of primary goods, and also allows us to discriminate . between compensation for handicaps and compensation for expensive tastes. Scanlon's schematic picture also frees the utilisation of primary goods from criticisms raised by Amartya Sen. Lastly, I discuss arguments advanced by Susan Hurley which enable an interpretation of Rawls's original position device which is independent of the luck-neutralising aim. Her arguments are extended as a criticism of Dworkin's hypothetical insurance market.
