Abstract: The aim of this study was to investigate the extent to which students' understanding of key words in examination questions might influence their performance as illustrated by the number of subjects in which they obtain pass grdades in the Cambridge Overseas School Certificate Examination (COSCE). The term used to refer to key words in this study is metalinguistic. It is a term that means more than what Kemp (2006, p.1) refers to words or phrases that re used to describe language as an object of study. Procedurelly, questions were designed to assess students' understanding of metalinguistic terms. The percentage scores of the metalinguistic tests were calculated and then compared with the number of 'O' level passes obtained by students to determine whether high scores in the metalanguage tests were comparable to the number of 'O' level passes obtained by the reserch subjects. It was discovered that high metalinguistic test scores were asssociated with greater 'O' level passes and low scores, with fewer 'O'level passes.

Abstract: Uptake for lead, copper, cadmium, nickel and manganese from aqueous solution using the Moringa oleifera seeds biomass (MOSB) and amine-based ligand (ABL) was investigated. Experiments on two synthetic multi-solute systems revealed that MOSB performed well in the biosorption and followed the decreasing orders Pb(II)>Cu(II)>Cd(II)>Ni(II)>Mn(II) and Zn(II)>Cu(II)>Ni(II). The general trend of the heavy metal ions uptake by the amine-based ligand followed decreased in the order Mn>Cd >Cu> Ni>Pb, which is the reverse trend for what was observed for MOSB. Comparing the single- and multi-metal solutions, there was no clear effect in the biosorption capacity of MOSB suggesting the presence of sufficient active binding sites for all metal ions studied. The MOSB performance is also not affected by pH in the range 3.5–8. URI: http://hdl.handle.net/10311/1039 Files in this item: 1

Abstract: In this paper, I intend to support Schechner's (1988:197) argument that "to be in trance is not to be out of control", and that in trance or possession the performer does exhibit elements of acting. Schechner mentions that two processes are indentifiable in performance: the performer is either "subtracted" in a performance closely resembling the art of the shaman who acts in ecstasy or what Jerzy Grotowski calls the "holy actor", or the performer is "added to" or "doubled", according to Antonin Artaud, in the process of performing. This "doubled" actor is considered to be in trance, something Schechner likens to Constantin Stanislavski's "character actor". In defining these two phenomena and other forms of acting, my intention in this paper is to prove that the whole of Africa is a gold mine of artistic performances. I intend to prove this by analyzing the acting styles and levels in Zimbabwean traditional performances. In traditional Zimbabwean performances, acting is realized in different social functions and contexts. In the contexts of this paper, acting means to feign, to simulate, to represent, to impersonate. (E.T. Kirby 1972 3) Defining acting and instances where acting is realized. Secondly, I will show how Zimbabwean societies use these define/identified qualities in different contexts. Thirdly, I will judge the levels of acting regarding their seriousness, commitment and functions. To achieve these aims, I will analyze four categories of performances, storytelling, childrens's make-believe, rituals and ceremonies. URI: http://hdl.handle.net/10311/861 Files in this item: 1

Abstract: This paper assesses the success and sustainability of Community-Based Natural Resource Management (CBNRM) in the Okavango Delta. It does so by asking the following questions: a) to what extent has CBNRM contributed to sustainable natural resource use, rural economic development, enhanced rural livelihoods and benefit sharing? b) To what extent has power been devolved to the rural communities especially in relation to resource ownership and management? c) What are the existing and potential challenges facing the successful implementation of CBNRM in the Okavango Delta? With illustrations from the three CBNRM projects of Okavango Community Trust, Okavango Kopano Mokoro Community Trust and the Khwai Development Trust, this paper notes that local communities have successfully established community trusts as institutions to provide leadership in their participation in tourism and natural resource management. They also derive socio-economic benefits from CBNRM such as the participation in decision-making, employment and income generation. However, the lack of entrepreneurships and managerial skills, understanding of the concept of CBNRM, poor benefit sharing on CBNRM participants, and enclave tourism are some of the challenges that face CBNRM in the Okavango Delta. In the event that empowerment issues especially training and capacity building are successfully addressed, CBNRM in the Okavango Delta has the potential to be a successful model of community-based tourism.

Abstract: Botswana has high HIV prevalence among pregnant women (37.4% in 2003) and provides free services for prevention of mother-to-child transmission (PMTCT) of HIV. Nearly all pregnant women (.95%) have antenatal care (ANC) and deliver in hospital. Uptake of antenatal HIV testing was low from 1999 through 2003. In 2004, Botswana’s President declared that HIV testing should be ‘‘routine but not compulsory’’ in medical settings. URI: http://hdl.handle.net/10311/330 Files in this item: 1

Abstract: Luiswishi is a Congo-type Neoproterozoic sediment-hosted stratiform Cu–Co ore deposit of the Central Africa Copperbelt, located northwest of Lubumbashi (DRC). The ores form two main Cu–Co orebodies hosted by the Mines Subgroup, one in the lower part of the Kamoto Formation and the other at the base of the Dolomitic Shales Formation. Sulphides occur essentially as early parallel layers of chalcopyrite and carrolite, and secondarily as late stockwork sulphides cross-cutting the bedding and the early sulphide generation. Both types of stratiform and stockwork chalcopyrite and carrolite were systematically analyzed for sulphur isotopes, along the lithostratigraphic succession of the Mine Series. The quite similar d34S values of stratiform sulphides and late stockwork sulphides suggest an in situ recrystallization or a slight remobilization of stockwork sulphides without attainment of isotopic equilibrium between different sulphide phases (chalcopyrite and carrolite). The distribution of d34S values ( 14.4& to +17.5&) combined with the lithology indicates a strong stratigraphic control of the sulphur isotope signature, supporting bacterial sulphate reduction during early diagenesis of the host sediments, in a shallow marine to lacustrine environment. Petrological features combined with sulphur isotopic data of sulphides at Luiswishi and previous results on nodules of anhydrite in the Mine Series indicate a dominant seawater/lacustrine origin for sulphates, precluding a possible hydrothermal participation. The high positive d34S values of sulphides in the lower orebody at Luiswishi, hosted in massive chloritic–dolomitic siltite (known as Grey R.A.T.), fine-grained stratified dolostone (D.Strat.) and silicified-stromatolitic dolomites alternating with chloritic–dolomitic silty beds (R.S.F.), suggest that they were probably deposited during a period of regression in a basin cut off from seawater. The variations of d34S values (i.e. the decrease of d34S values from the Kamoto Formation to the overlying Dolomitic Shales and then the slight increase from S.D.2d to S.D.3a and S.D.3b members) are in perfect agreement with the inferred lithological and transgressive–regressive evolution of the ore-hosting sedimentary rocks [Cailteux, J., 1994.

Abstract: Public support for source separation schemes in developing countries is still subject to continuing debate and limited work has been directed at understanding its manifestations. The purpose of this survey was to assess existing and potential levels of household participation in waste source separation as well as establishing the role they could play in future source separation schemes in Gaborone. Questionnaire based surveys were used to elicity information from households about their awareness of recycling and recycling initiatives, attitudes and willingness to participate in source separation schemes. The survey involved 17 households who participated in a pilot source separation scheme and 284 households who did not. The results showed that the majority of households are aware of recycling and recycling initiatives, but this awareness does not necessarily translate into participation in recycling activities in the absence of incentives and visible systems. It was also found that the majority of households are willing to participate in future source separation schemes, however, such willingness was primarily limited to separating materials that at the time had known available markets and were easy to separate.

Abstract: This study surveys the existing recreational facilities in Southern Botswana schools for children with disabilities. All the 14 schools for indviduals with disabilities in Southern Botswana were used for the study. The recreational facilities considered included archery, bowling and goal-ball facilities, swimming pools, badminton, basketball, handball, netball, tennis, and volleyball courts,soccer and softball pitches. Using the statistic for the test for significance of proportions, at 0.05 alpha level, it was observed that the proportion of archery, bowling and goal-ball facilitites, badminton, handball, netball and tennis courts and softball pitches in the schools were not significantly provided for by the schools' managements. However, the proportion of basketball and volleyball courts, soccer pitches, swimming pools and table tennis boards provided were not significantly different from the 0.5 (50%) chosen as the expected proportion. Hence these were accepted as having been adequately provided for. The researchers recommend assistance from individuals, non-governmental organisatios and the government of the Republic of Botswana for the provision of more recreational facilities for these children with special needs.

Abstract: The Project Management Section at the University of Botswana has been undergoing a test to transform the section from an education based faculty to a research based faculty. The test was initiated by a Fulbright Scholar (FS) from the Performance Based Studies Research Group (PBSRG), bringing a new research model, a new risk management (RM)/project management (PM) model, and a concept of a research based graduate education that had been very successful at PBSRG. They proposed increasing the level of research activity of the UB PM section by merging the graduate MPM program and the industry research effort. They proposed using a research based graduate program, treating the graduate students from industry as a resource instead of a student, and their organizations as a potential testing laboratory. The mechanism to make the effort a success is the very powerful technology of the Performance Information Procurement System (PIPS) and the deductive logic of the Information Measurement Theory (IMT). This paper captures the case study results and future potential of the concept, highlighting the operational model to sustain the research platform in an underdeveloped country in a resource starved environment.

Abstract: HIV-related fatigue is a debilitating and disabling symptom that persists for months and years. In 743 HIV/AIDS patients from Southern Africa, the authors found ratings of HIV-related fatigue to be highly prevalent. The authors conducted a secondary data analysis within the theoretical context of the University of California, San Francisco Symptom Management Model. The analysis focused on 538 patients who reported fatigue to investigate correlates and predictors of fatigue severity in relationship to demographic and HIV/AIDS illness indicators, as well as HIV-specific physical and psychological symptoms. A hierarchical regression model explored the contributions of those five blocks on fatigue severity. Of the 47% of the total variance in fatigue severity, a combination of variables within the health and illness block (6%), the physical symptoms block (7%) and the psychological symptom block (2%) contributed significantly to the increase in fatigue severity scores. Fatigue severity in Southern Africa was moderate, and the factors contributing to the perceived fatigue were most likely related to symptoms of acute HIV disease (such as fever and gastrointestinal problems). In conclusion, fatigue severity is less impacted by demographic or environmental variables but much more by co-occurring symptoms and HIV disease severity. The results of this study imply the need for more research to understand if improvements in water quality and access to food would prevent infection and diarrhea and whether sufficient access to antiretroviral treatments to manage the HIV infection would improve fatigue and co-occurring symptom profiles.

Abstract: This study describes the symptom experience of 743 men and women living with HIV/AIDS in Botswana, Lesotho, South Africa, and Swaziland. Data were obtained in 2002 by using a cross-sectional design. A survey of participants included 17 sociodemographic items and the 64-item Revised Sign and Symptom Checklist for Persons with HIV Disease. Results indicate a strong correlation between the frequency of reported symptoms and their intensity (r .84, p .00). Participants who reported having enough money for daily expenses also reported significantly fewer symptoms. There were no significant differences in symptom frequency between men and women or by location of residence. The study showed a complex picture of HIV-related symptoms in all four countries. Because of the high levels of symptoms reported, the results imply an urgent need for effective home- and community-based symptom management in countries where antiretroviral therapy is unavailable to help patients and their families manage and control AIDS symptoms and improve quality of life.

Abstract: This essay examines, through taxation, the relationship between British colonial administrators, Tswana Dikgosi (chiefs) and their subjects in the Bechuanaland Protectorate from 1899 to 1957. It argues that since Bechuanaland became a British territory through negotiations the Tswana rulers were able to protect their interests aggressively but with little risk of being deposed. Moreover, the Tswana succession system by primogeniture worked to their advantage whenever the British sought to replace them. Taxation was one arena where this was demonstrated. Although consultation between the Dikgosi, their subjects and the British was common, subordinate tribes sometimes fared badly under Tswana rule.

Abstract: This paper discusses student engagement in learning in junior secondary schools classes. Concern has been raised on the declining performance of students in junior secondary schools. The 2009 junior certificate results are a testimony to this concern. This paper investigates the response of Botswana junior secondary school teachers on three subscales, the Teacher Sense of Self Efficacy scale (TSES), efficacy in student engagement, instructional strategies and classroom management. The findings of this study suggest that teachers do not fully engage students in learning activities. Data was collected using a survey instrument administered to 1006 participants. Based on this study, decline in student performance can be linked to teachers failing to fully engage students in learning. Recommendations on how to engage students in learning are offered.

Abstract: This article focused on the training needs of serving teachers for the enhancement of school performances. It sought to achieve this by involving a selected group of teachers and head teachers in the completion of a questionnaire. The questionnaire was reinforced by interviews conducted on a few teachers and head teachers. The study concluded that for teacher development programmes to achieve their intended goal of improving the teaching and learning processes, they should of necessity be based on the actual problems teachers encounter in the classroom. Not only should in-service programmes target teachers, but head teachers also need training on an ongoing basis to strengthen their managerial skills.

Teacher trainees’ level of preparedness for inclusive education in Botswana schools: need for changeMukhopadhyay, S.; Molosiwa, S.M.; Moswela, E. (IJSRE, http://www.ijsre.com, December NaN, 2009)[more][less]
Abstract: The purpose of this study was to explore the extent to which the University of Botswana special education teacher-training programme. Inclusive education has gained significant currency nationally and internationally. Inclusive education demands that the teacher should be able to meet the needs of students with disabilities in a regular/ ordinary classroom. The success of inclusive education rests on quality teacher preparation gearing towards inclusive education. How teachers are prepared is intrinsically linked to the quality of education provided in the schools. Qualitative research method was used to explore how teachers are prepared for inclusive education in Botswana. Eighteen final year special education student teachers were involved in two focus group discussions. Findings of this study revealed that special education student-teachers were not prepared to meet the learning needs of diverse categories of learners with disabilities in inclusive settings. Based on the findings of this study, a teacher preparation model is proposed for successful implementation of inclusive basic education in Botswana.

Abstract: Attempts to improve the quality of education in Botswana have, inter alia, included an emphasis on a learner-centered pedagogy. Attempts at implementing this pedagogy have been made within the ambit of the technical rational model of curriculum development. The attempts, however, have produced inconclusive results, and these results have often been rationalized in technicist terms, e.g. as being due to lack of resources and poorly trained teachers. Overlooked in this technicist model are the teachers' perspectives on the innovation. Using the case-study approach within the rubrics of the qualitative research paradigm, this study sought to establish the perspectives of geography teachers in a senior secondary school in Botswana vis-a-vis the learnercentered pedagogy advocated in Education for Kagisano (Social Harmony), a report produced by the 1977 Commission on Education. The findings indicated that teachers' classroom practices were influenced by many factors other than technical ones: these included the teachers' assumptions about the nature of knowledge and the ways it ought to be transmitted, their perceptions of students, and the goal of schooling. It also emerged that their assumptions were incongruent with the basic tenets of the learner-centered pedagogy. The findings, then, are an indictment of the technical rational model of change implementation applied in Botswana. They indicate that disregarding what teachers know and think about their taken-for-granted classroom practices when effecting change can lead to disappointing results.

Abstract: This paper focuses on teachers’ experiences with implementing a modified International General Certificate of Secondary Education (IGCSE) physics syllabus in Botswana. The syllabus, characterised by a new organisational and pedagogic paradigm, is a significant shift from the traditional ‘‘teacher-proof’’ syllabus to one that is flexible, nonprescriptive and student-centred. Through data from discussions and interviews with teachers, it emerged that policy statements on the nature of the syllabus were contradictory and confusing to guide both the adoption and implementation of the syllabus. It also emerged that teachers accorded the core curriculum component of the syllabus a lower priority and status than the extended curriculum component. The findings also reveal that considerable overlaps in the core and extended curriculum components of the syllabus blurred the distinction between the two as well as weakening prospect of fidelity of adoption and implementation. The resulting ‘innovation gap’ invariably means that the ideals of the syllabus and the associated paradigm shifts are possibly not realised in teaching in Botswana. The findings generally underscore the importance of clear guidance and policy statements on any new syllabus, and indeed, a new curriculum. Possible directions in future research would be to investigate innovation gaps that might be manifest in teaching. URI: http://hdl.handle.net/10311/499 Files in this item: 1
