- Description: This study was conducted at the school where I teach which is a semi-rural secondary school (Grade 8-12) situated in Omuthiya Town in Oshikoto region, Namibia. The new curriculum that has been implemented in Namibia, has posed challenges in how best to put the curriculum into practice at this school. It was this challenge that triggered my interest in doing a research study with the aim of improving my practice. Essentially, the study sought to gain insight into whether integrating learners’ prior everyday knowledge and experiences of acids and bases in conjunction with practical activities using easily accessible materials enabled or constrained meaning-making of this topic. This study is located within an interpretive paradigm. Within this paradigm, a qualitative case study approach was adopted with my Grade 9 class. Data were gathered using document analysis, videotaped lessons and observations by a critical friend, stimulated recall discussions while watching the videotaped lessons as well as focus group interviews with the learners. An inductive analysis to discover patterns and themes was applied during the data analysis process. The themes were further turned into analytical statements. Data sets were also analysed in relation to the research questions posed by this study. The validation process was achieved by using a variety of data gathering techniques. I watched the videotaped lessons with a teacher who observed the lessons and transcripts of the interviews and a summary of discussions were given back to the respondents to verify their responses and check for any misinterpretations, a process known as member checking. I also translated what the learners said in Oshiwambo, their home language, into English. The findings from the study revealed that the use of learners’ prior everyday knowledge and experiences of acids and bases facilitated meaningful learning during teaching and learning. Furthermore, linking learning to learners’ everyday experiences enabled them to learn scientific concepts in a relaxed and non-threatening environment. However, linking learners’ prior knowledge and experiences to conventional science (textbook science) proved to be a challenge. My recommendations are that teachers need support in their endeavors to incorporate learners’ real life experiences into their teaching and learning repertoires. Another aspect of my study that deserves further research is the role that language plays in implementing the curriculum.

- Description: This thesis aims to critique the Universal Declaration of the Rights of Mother Earth and its underlying moral justification in order to provide a stronger and improved version of both. In Chapter 1 I explore what sort of moral justification is necessary to establish the Universal Declaration on firm grounds and explore its relation to environmental ethics and rights discourse. I argue that a non-anthropocentric perspective is necessary to justify the Universal Declaration’s rights. In Chapter 2 I explore the underlying justification of the Universal Declaration as discovered in the works of Cormac Cullinan and Father Thomas Berry. I argue that their ethical framework is indeterminate, has many ambiguities and uncertainties, and, among other problems, it does not provide a clear action-guiding framework. In Chapter 3 I develop an alternative justification for the Universal Declaration. I argue against many predominant moral theories, that in light of our best scientific and moral understanding we should expand the realm of moral concern to include all living beings, a moral theory I call Life’s Imperative. In Chapter 4 I illustrate that Life’s Imperative is a much stronger, more coherent justification for the Universal Declaration, one that coheres with both our best understanding of the natural world and our relation to it, and to an environmental ethic reflective of that relationship. Unfortunately many of the weaknesses in the current implicit justification of the Universal Declaration have also led to it enshrining rights that are themselves problematic. In order to address these issues, I revise its rights to accord with the stronger justification that I established in Chapter 3. The end result of doing so is a revised version of the Universal Declaration
