- Description: The study sought to investigate the effect of using English as a language of learning and teaching on learner academic performance in the senior phase of Mthatha District, Eastern Cape Province. This study employed a mixed-method approach. The researcher used both qualitative and quantitative methods to collect data. The study was conducted in 3 semi-rural senior secondary schools that were conveniently selected. The quantitative part employed Likert-type scale questionnaires that were administered to 10 Mathematics (Math), 10 Natural Sciences (NS) and 10 Social Sciences (SS) teachers making a total of 30 teachers and a total of 30 learners from grades 8 and 9. For the qualitative part, nine (9) teachers and eighteen (18) learners from the selected schools were interviewed. The 18 teachers in three schools were observed as they taught Grade 8 and 9 learners in their respective classes. Qualitative data were, thus, gathered through interviews and observations. Quantitative data was collected using Likert-type scale questionnaires and was analysed using descriptive statistics and Microsoft Excel. The voice recorded qualitative data from the participant’s responses were transcribed and analysed manually through coding, forming categories and themes that were used for data presentation. These are some of the findings: The majority of learners do not understand English, therefore, it was difficult for them to understand the teaching and learning of the selected subjects in Senior Phase (SP) using English as the language of learning and teaching (LoLT); Although the majority of learners reported that they usually use English as a LoLT and their home language when learning the selected subjects, they still struggled to ask and answer questions in English in a classroom and during examinations; Learners who experience difficulties in learning the selected subjects through the use of English as a LoLT in SP, were taught in their home language (isiXhosa) by their teachers; English and isiXhosa, in the form of code-switching, were used when teaching the selected subjects; Inadequate teacher training and preparation made it more difficult for the learners to perform well in the selected subjects. The study recommends that: The Department of Education should conduct enough workshops to help HOD’s and teachers who teach the selected subjects to keep abreast of new developments in these subjects. These should be integrated with appropriate teaching strategies and learning and teaching support materials. Keywords: English as the language of learning and teaching, teaching strategies, learning, teaching support materials. , Thesis (D.Ed) -- Faculty of Education Sciences, 2021

- Description: This study assesses motivational preferences of employees in a multinational context in Sub Saharan Africa. Using the Grundfos group operating sites in Ghana, Kenya and South Africa as a case study, the study explores quantitative data on possible differences in employee motivational factors based on selected variables such as location, length of service and managerial status. Questionnaires were employed in collecting data from 131 participants from the three locations of Grundfos Sub Saharan Africa (SSA). Results of the study reveal that the factor “equal treatment of employees” is considered most important among the respondents. It is also noted that there were no significant statistical differences among the participants based on the examined variables. Policy and practical implications of the findings of this study are discussed, particularly around the development and implementation of Human resources policies that address employee perceptions of equity. This study makes a contribution to existing literature on employee motivation in multinational settings. Keywords: Employee motivation, motivational factors, multinational context, Sub-Saharan Africa

- Description: Background: Spilanthes filicaulis is a tropical herb implicated as a memory enhancer in ethnomedicine. Objective: The study investigated acetyl/butyryl cholinesterase inhibitory and antioxidant activities of different extracts of S. filicaulis whole plant and correlated them to its phytochemical constituents. Methods: The powdered whole plant was successively extracted with n-hexane, ethyl acetate and methanol. Acetyl cholinesterase (AChE) and Butyryl cholinesterase (BuChE) inhibitory activity were evaluated by Ellman colorimetry assay. Antioxidant activity was tested using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, ferric reducing power and nitric oxide scavenging assays. Total phenolic, flavonoid and tannin were estimated using standard methods. Correlation was determined using Quest Graph™ Regression Calculator. Results: Various extracts exhibited concentration-dependent AChE and BuChE inhibitory activity with ethyl acetate extract being the highest with IC50 of 0.77 μg/mL and 0.92 μg/mL for AChE and BuChE respectively. The ethyl acetate extract also showed the highest reducing power when compared with the other extracts. The methanol extract had slightly higher phenolic and flavonoid content and showed the highest DPPH radical scavenging effect. DPPH scavenging, AChE and BuChE inhibition had high correlation with the total flavonoid content with R2 values of 1.00, 0.800 and 0.992 respectively while nitric oxide scavenging had high correlation with phenolics and tannins with R2 = 0.942 and 0.806 respectively. Conclusion: These results show that the extracts of the whole plant of S. filicaulis possess significant AChE/BuChE inhibitory and antioxidant properties, mostly due to its flavonoid content, suggesting the possible use of the plant in neurodegenerative diseases such as AD.
