Design of a Flood Water Powered Water Pump
(National University of Science and Technology (NUST)., 2007-07-17) Dewa, Mncedisi; Mhlanga, Samson; Maphosa, N.; Phuthi, Nduduzo
The paper set to discuss the research to develop a machine that collects water from flooded rivers and pumps it to a reservoir so that it can be used to water crops during the interludes of dry spells that characterize the Zimbabwe rain season. This water is not necessary intended to irrigate the crop on full scale, but just to bridge the crop and sustain it during the critical weeks of the dry spells which usually stresses the crop beyond recovery even after the rains resume. The simple machine designed relies totally on the force of the flood water to pump water from the river and send it to the reservoir, thus making it possible for the machine to be used in the rural areas where there is no electricity. The cost of the model that was built is given as well as the pictorial view of the model.
E-Learning Environments in Undergraduate Design and Technology Courses
(2014) Phuthi, Nduduzo; Molwane, Olefile Bethuel
When e-learning and other information and communication technologies (ICT’s) became accepted in both distance and face-to-face modes of learning in tertiary education, expectations were high that they would, within a reasonable time frame, yield visible and perhaps irrefutable gains in course delivery strategies and revolutionise both learning content knowledge and access to it. In developing countries it was hoped that there would be benefits in tapping into a knowledge revolution currently dominated by industrialised countries, who are by far the greatest contributors and beneficiaries. The University of Botswana’s (UB) efforts, initiated in 2001, at technological transformation in teaching and learning for meaningful quality processes and outcomes have been evaluated by researchers, reviewers and participants. Comments have been made such as, ‘substantial progress, but many challenges” “very useful teaching support tool for large classes, but there is need to address key background issues” , “students share learning through educational technologies, but appropriate learning environments are required” . It has been evident that although a lot has been done at institutional management level to promote adoption and implementation of e-learning as a rule at UB, the ideal situation has not materialised. Much of the problem seems to emanate from the interaction between key players, such as top management, the teaching staff and students. This paper reports on an on-going qualitative study that was carried out in order to negotiate and establish acceptable quality and effectiveness of e-learning envisaged by both the staff and students in a course that was not online at the time, in preparation of launching the course online in the next cycle. The action learning research study aimed at constructing an environment and a disposition towards e-learning mutually negotiated between students and their lecturers. Data was collected through various student-lecturer and student-student interaction processes such as classroom lecture, internet search, group presentations, tests, assignments, classroom observations, questionnaires, and video script analyses. Preliminary findings indicate that most students are enthusiastic about adopting e-learning if they have been adequately pre-oriented into the method and are consistently guided by caring and competent staff. They also will appreciate quality and effective learning if this is negotiated with someone who can articulate standards of performance.
Indigenous Design and Production Entrepreneurship: Sector Performance Audits and Proactive Support
(Bulletin of the Centre for Academic Development, 2008-03) Phuthi, Nduduzo; Letsatsi, M.T.
There is little doubt, if at all, that one of the most urgent goals for developing Africa is genuine economic emancipation, which would, in turn, expedite solutions to the persistent problems of poverty, disease, ignorance, civil strife, and many others. This emancipation requires deliberate, proactive home-grown initiatives that gradually unshackle economically deprived nations from dependence on imported expertise, ideas, tools and products, to a culture of planned local design, production and trade in globally competitive wares and products. Such a mindset has evolved over the years in industrialised countries through steady and cumulative growth from small to medium to large-scale business enterprises. In this paper we propose a systematic audit for small and medium-scale enterprises in the design and production business which would assist to identify the necessary support needed to propel the local small and medium-scale sector into national and global competitiveness.
Needs-based knowledge processing through university- community partnerships: higher education inroads into rural community development in Zimbabwe
(The UNESCO Forum on Higher Education Research and Knowledge, 2008-11) Phuthi, Nduduzo; Gundani, M.P.D.; Sibanda, Isaiah M.
Knowledge, the ultimate competitive advantage for any modern community or organization, gives its possessor a unique and inherently protected commodity for survival and development. Today's universities are among those organizations credited for spearheading and sustaining the on-going knowledge revolution. In developing countries, universities have come to playa key role within their own societies in a wide range of developmental issues even though they often find themselves acutely outclassed in the competitive international knowledge network (Altbach, 1998). Notably, many universities need sensitization for them to prioritize the integration of local and alien knowledge that should address broader sustainable development needs as perceived by the affected communities. Comparatively, the superior military, economic, intellectual and technological accomplishments of industrialized countries give some of their universities extensive, jealously-guarded power, prompting them to assert themselves as 'central' institutions within their countries and in the global knowledge arena. The third world universities remain 'peripheral', tending to copy developments from abroad, producing little that is original, and generally not at the frontiers of knowledge. Within developing countries, the Western-sourced education, science, technology and Western human development models appear to perpetrate a socio-economic and knowledge gap among citizens, creating a conservative traditional culture alongside a neo-Western one.
Partnerships in Education, Training and Management for Sustainable Natural Resources Processing in Zimbabwe’s Rural Communities
(2014) Phuthi, Nduduzo; Sibanda, A.J.P.
In the course of their everyday academic business, universities in developing countries turn over large volumes of mainly foreign-sourced knowledge, while on the other hand typical communities in rural areas are starved of vital information for their own survival and development. Partnerships between universities and their immediate communities have a potential to turn the fortunes of both parties in economic ways. In the area of natural resources harvesting for commercial purposes, the university- community partnership plays a critical role in fulfilling mutual needs and tackling environmental stability. This paper explores the perceived roles of education, training and management practices on encouraging rural communities to recognize natural resources within their environments and to develop appropriate capacity to sustainably exploit them for economic benefit. Elaborating on the views of selected players and with reference to textile materials sourcing and processing, the paper identifies the complementary functions of education, management and rural communities in developing informed appreciation for sustainable harvesting of natural resources.
A Quasi-Linear Model Of Design Cognition
(The Clute Institute, 2010-11) Phuthi, Nduduzo; Kumar, K.L.; Molwane, Olefile Bethuel
The continuum of human learning has been the subject of research by behaviourists, cognitivists, constructivists and lately by neural scientists among others. The style and order of learning have also been identified, notably by Benjamin Bloom et al (1956) and Gagne and Briggs (1992). Skills-learning has been the subject of attention in competency-based learning strategies. Yet another milestone in the continuum of learning is to be innovative and creative, which enables a learner to conceive and design new objects and concepts. Design cognition is an under-explored faculty of humankind. Human capability to design appears to be a complex phenomenon influenced by several factors, implicitly or explicitly, such as socio-educational background, learning to think innovatively, interaction with innovators and creators, exercising initiative, experimenting with new ideas, creating designs with confidence and finally moving into seeking design patents and making commercial use of design. In this paper the authors develop first a linear model of acquiring design capability and then modify it to a quasi linear model after validation by interaction with a sample of design students and design professionals through analysis and reflection on questionnaire responses with both qualitative and quantitative data. The proposed model promises to be a useful tool for design educators in several overlapping areas of design.
The Student Factor in building an e-learning culture: Experiences at the University of Botswana
(Academic Publishing Limited, 2008-06) Phuthi, Nduduzo; Molwane, Olefile Bethuel
This paper presents findings of a small study on the prevailing characteristics and preferences of university students that can be linked to their motivation to adopt and sustain e-learning as their key learning strategy. The qualitative case study was carried out through a questionnaire survey, interviews and classroom observations of third year students enrolled in a five-year degree programme in design and technology at the University of Botswana. The university has embarked on a deliberate path of technological transformation through the University of Botswana e-learning initiative (UBel) which has been significantly supported by the institution’s management (Thurab-Nkhosi et al 2005). In this study, students were taken through a variety of learning activities incorporating internet-searches, group work and peer presentations, media-enhanced lectures, and guest lecturing. Through these activities, the students were encouraged to discover and communicate their strengths and preferred learning styles in an attempt to inform their readiness and motivation to embark on full-scale e-learning as desired by UBel. Owing to various reasons, the bottom-up approach to organizational transformation and innovation diffusion is often less explored because of, among others, problems of feasibility and expediency. The largely imported e-learning technology is often assumed transferable and appropriate for all students, regardless of background, orientation and aspirations. While e-learning is indeed suitable for the maturing and independence- seeking university learners who need more guidance than shepherding, few academics appear to understand who their students are, and which of their characteristics can be useful to bring about identified change in the learning and teaching processes. It has been suggested that university students, the most sensitive section of society, are open to ideas and have unsettled minds looking for change, while the universities they attend are centres of revolutionary ideas (Dibaj 2000). There are opportunities to derive from this. For their part, higher education students in Botswana have been, and are being, shaped in the realm and mindset of the prevailing socio-cultural environment around them. Being citizens of a fast economically developing country with a rare ‘inborn’ multi-party democracy described as ‘an oasis of tolerance and non-violence amid civil strife and political chaos’ among its neighbours (Rule 1988), Botswana university students are likely to portray situation-consistent behaviours and attitudes towards learning in general, and e-learning in particular. The findings of this study suggest that the surveyed students were largely expressive but unempowered knowledge and information recipients whose intellectual potential and multiple intelligences (Pritchard 2005) were not being fully exploited. They preferred less challenging learning tasks only because they were used to them, but would otherwise welcome active, interactive and information-rich experiences in their learning, with e-learning as a definite favourite.
Transforming Higher Education for Effective Technical and Vocational Skills Delivery in Zimbabwe
(African Higher Education Research online, 2007) Phuthi, Nduduzo; Maphosa, N.
The major thrust of technical and vocational education (TVE) worldwide is to address issues of youth unemployment, poverty and international competitiveness in skills development towards current and projected opportunities and challenges (McGrath, 2005). Such issues are crucial to Africa’s dignity and survival in the fast-changing global environment. African countries and their governments have been challenged to take cues from their industrialized counterparts to seriously consider the role of higher education and training in the quest for economic emancipation and social stability. In developed countries, higher education, for its part, is facilitating the elevation of human intellectual capital well above other forms of human endowment. The International Bank for Development and Reconstruction/World Bank (2000) has observed that: “Today, global wealth is concentrated less and less in factories, land, tools, and machinery. … Human capital in the United States is now estimated to be at least three times more important than physical capital. … The developed world is reacting quickly, with education a major political priority. High quality human capital is developed in high quality education systems, with tertiary education providing the advanced skills that command a premium in today’s workplace.” TVE has played an important role in charting the course for human civilization into modern times. Most of today’s increasingly more complex and specialized technical jobs require systematic strategies of handing down vital cumulative skills to younger generations. It has been noted that in developing countries, TVE is one of those sections of education given much less priority in policy formulation, funding and monitoring than other sections such as basic education. In this paper we analyze some pertinent developments and report on a survey of major policies and activities that promote and recognize the place and role of technical and vocational education in Zimbabwe in relation to the demands of this type of education for the economic development of the country. The challenge to transformation in our developing economies as always is whether to emphasize cultural and contextual differences and national idiosyncrasies instead of international similarities, competitiveness and comparative indicators. (Watson,1994). In order to play its part well as leading and advising, higher education must itself be seen to transform.
