Background information on animal and human communication is provided with a focus on leadership styles and skills. Selected documented Xitsonga oral prose narratives and narratives about current leaders were collected and analysed. The study is guided by the Critical Discourse Analysis, Interactional Sociolinguistics and Social Constructionist approaches. Data was classified per the selected categories of the verbal and nonverbal communication strategies. Communicative behaviours of characters in leadership positions in the oral prose narratives and those of the current societies were interpreted and analysed based on the selected approaches. Findings revealed that indeed, current leaders lack management skills and communication strategies. Examined leadership principles expected from many societal leaders were found to be non-existent. Cases of power mismanagement and dominance in the form of negative manipulation or influence were identified from their misuse of verbal and nonverbal communication strategies. Greed, anger and defective religious or ancestral beliefs were sources of such power mismanagement and dominance. Most subordinates suffered emotional, verbal and physical abuse, sexual harassment and displacement at the hands of their leaders in the society. Current leaders can learn much about management skills and communication strategies from the African languages oral prose narratives, particularly Xitsonga oral prose narratives. The study reveals that folklore is rich with ancestral wisdom, which can assist in current leadership problems. The study can be valuable to both leaders and their subordinates. Suggestions and recommendations are offered to the current leaders to help them decide on adjusting their communication strategies and ultimately changing their communicative behaviour. Current leaders should take a leaf from the wisdom embedded in oral prose narratives to address their lack of management skills and communication strategies to improve communication between them and their subordinates. / African Languages / D.

The study investigated the strategies used in teaching geometry in primary six as well as the perception of teachers on geometry vocabulary teaching, how geometry vocabularies were taught and, lastly, how the teaching of geometry vocabulary influenced primary six learners’ performance in geometry. The Van Hiele Theory of geometrical thinking and the Constructivist Theory of learning guided the study. The study conveniently sampled 250 primary 6 learners and 7 primary 6 mathematics teachers from three privately-owned primary schools in the Greater Accra Region of Ghana. It combined quantitative and qualitative approaches, using O1–X–O2 design. Data collection instruments were 5-point Likert type scale questionnaires (one for teachers, one for learners), a pre-test and post-test of basic geometry, and a semi-structured one-on-one audio-recorded interview of a selected number of learners and all seven teachers. An intervention was carried out in-between the pre-test and post-test, where the researcher taught geometry vocabulary to participants. Quantitative data were analysed using tables, charts, and simple tests while the qualitative analysis involved the transcription of interviews that were coded, categorised and themed. The study found that geometry vocabularies were not taught and that the most commonly used strategy for teaching geometry was the drawing of 2-D shapes and models of 3-D objects on the board. The pre-test and post-test scores were analysed using a paired t-test and the results indicated that the intervention had a positive effect. The qualitative and quantitative results confirmed that the teaching of geometry vocabulary improved learners’ performance in geometry. The study developed a prototype lesson plan for teaching 3-D objects, a geometry vocabulary activity sheet, a sample assessment for prisms and pyramids and recommends a curricular reform to inculcate the teaching of geometry vocabulary in the curriculum with a geometry vocabulary list for learners in each year group, as contribution to knowledge in mathematics education. The study recommends further research to investigate the effect of geometry vocabulary teaching on learners’ performance in geometry across all year groups in the primary school. / Dyondzo a yi lavisisa maendlelo lawa ya tirhisiwaka ku dyondzisa geometry ya tidyondzo ta le hansi ta ka ntsevu, mavonelo ya vadyondzisi eka madyondziselo ya marito ya geometry, tindlela leti tirhisiweke ku dyondzisa marito ya geometry xikan’we ni ndlela leyi madyondziselo ya marito ya geometry ya khumbheke matirhelo ya vadyondzi va tidyondzo ta le hansi ta ka ntsevu.
