- Description: The Namibian Science curriculum promotes learners’ development of self-confidence, self-knowledge and understanding of the world in which they live. The world we live in is increasingly multimodal, necessitating a multiliteracy in learners in order for them to engage meaningfully with knowledge and skills. Furthermore, scientists themselves engage in a range of inscription practices. While verbal language is the primary medium through which scientific knowledge and concepts are constructed, communicated, and learned, visuals can help learners to gain knowledge that they may not receive from verbal explanation alone. The verbal and visual semiotic modes can also function in a complementarity way, and this is significant in contexts where science lessons are for the most part in a second language - as is the case in Namibia where the language of learning and teaching (LoLT) of English is commonly not the learners’ mother tongue. However, no studies were found exploring the nature of verbal-visual intersemiotic complementarity in the practice of Namibian science teachers, or whether it was related to the number of years of science teaching experience. This study thus aimed to explore the dynamics of verbal-visual intersemiotic complementarity in the classroom practice of three Junior Secondary Physical Science teachers, with varying amounts of science teaching experience, in the Oshana region of Namibia. This qualitative case study, on the dynamics of verbal-visual intersemiotic complementarity in science teacher classroom practice follows in the path of earlier studies which employed Systemic Functional Linguistics (SFL) in the analysis of multimodal discourse. This thesis is also informed by Social Constructivism in which the various semiotic modes are recognised as components of the toolkit for mediating learning. The study adopted the interpretive paradigm. Data collection involved lesson observations and semi-structured interviews. Data analysis involved identification and coding of themes and categories inductively. The results reveal that the participant teachers employed the full range of intersemiotic sense relations which literature outlines. It was found that the ideational meanings in the verbal and visual modes of the science teachers’ practice are lexico-semantically related through these intersemiotic sense relations. While some teachers utilised some intersemiotic sense relations more often than others, there were no correspondences evident between the use of verbal-visual intersemiotic complementarity and the number of years of science teaching experience. The results also indicated that different intersemiotic sense relations served different purposes in the science classroom. The verbal-visual intersemiotic complementarity in the participant teachers’ practice tended to focus on: physical material, processes, symbolism or resemblance. This study has significant implications, providing an empirical basis for informing pre-service Physical Science teachers’ training and guiding the in-service training of Physical Science teachers in Namibia. Since its effective use may not be left up to teaching experience, Namibian Physical Science teacher training programmes need to include the use of verbal-visual intersemiotic complementarity in order to equip and empower Physical Science teachers.

- Description: Teaching has a primary focus on engagement with students, but paradoxically, it can be experienced as lonely, private work, in classrooms behind closed doors, with an accompanying sense of deep disconnection from peers. When six experienced teachers sought to counteract this isolation, they formed a group which embarked on a shared journey of reflection and conversation, with the purpose of increasing selfknowledge, clarifying a sense of self as teacher, extending understanding of the selfhood of other teachers, and exposing the deeper sources of meaning underlying the vocation of teacher. This study sought to describe the information, opinions and beliefs which were exchanged among participants within the group and to describe the dynamics within the group. Furthermore, it sought to identify and describe the self-perceived impact of the experience of such a group, on the vocational vitality of each of the participants. Within an interpretivist epistemology a qualitative phenomenological research approach was adopted for the study. Data were obtained from two sources, consisting of transcripts of conversations from the meetings of a collaborative reflective group and from semi-structured individual interviews with group participants. These were analysed using an inductive approach with the aid of qualitative data analysis software: Atlas ti®. Findings from the study show that a high level of trust and a sense of safety were created through the use of guiding principles for meetings. Content chosen for reflective conversations and the general experience of meetings was perceived as providing a rare opportunity for participants to discover their selfhood as teachers. They reported that this understanding was further broadened by exposure to the selfhood of other teachers. Furthermore, members of the talk group reported that participation had resulted in a lowering of their sense of professional isolation and a renewal of vitality in their teaching. It is hoped that the findings from the study will inform an understanding of the experience of dialogue in a reflective, peer group where teachers focus on exploring together “who they are” as teachers. It provides valuable insights of the personal and professional transformations which can take place for teachers participating in conversations which focus on their inner landscape. Furthermore, the study has the potential to inform South African teacher professional development programmes with approaches which focus on teacher vocational renewal and vitality.
